GST Calculator India — The Complete Guide for Small Business Owners, Freelancers & Accountants

Look, I'll be honest with you. Most of the "GST calculators" you'll find online are either loaded with ads, ask for your email before showing the result, or spit out wrong numbers because they were coded by someone who never actually filed a GSTR-3B in their life. We built this one because our own team was tired of opening a spreadsheet every time we needed to work out ₹18,500 plus 12% GST. It should take three seconds. So we made it take three seconds.

But a calculator alone doesn't solve the problem. Ninety percent of the questions our support inbox gets aren't "how do I use the tool" — they're "should I charge CGST+SGST or IGST for a customer in Bihar", "my client in Mumbai says my Delhi invoice is wrong", "reverse GST kya hota hai". So this guide is the answer to every one of those questions. Bookmark it. Send it to your junior. Whatever helps.

Everything below is written from the perspective of someone who has actually filed monthly returns, dealt with a mismatched GSTR-2A, watched a client's ITC get blocked because the vendor didn't file on time. If you're brand new to GST, start from the top. If you already know your CGST from your SGST, jump straight to the formulas or the 15 real industry examples.

1. What GST actually is (and why it replaced 17 other taxes)

Before July 1st, 2017, Indian businesses were juggling excise duty, service tax, VAT, central sales tax, entertainment tax, octroi, luxury tax, entry tax, purchase tax, and about eight other cesses. Every state had its own VAT rate. Every product had a different classification. Small manufacturers spent more time doing paperwork than making things.

Goods and Services Tax — GST — collapsed all of that into a single national indirect tax with a common structure across states. It was voted into law under the 101st Constitutional Amendment Act, 2016, and rolled out on 1 July 2017. The idea, borrowed loosely from Canada's dual GST model, was simple: one tax, uniform rates, digital compliance, and — the big promise — no tax on tax.

That last bit is where Input Tax Credit (ITC) comes in, and it's the whole reason large corporates were willing to accept a compliance-heavy tax like GST. We'll get to ITC later. First let's understand the shape of the tax itself.

GST is a destination-based consumption tax. Meaning: the state where the goods or services are consumed gets to keep the tax revenue, not the state where they're produced. This one design choice is why every GST question eventually becomes a "place of supply" question.

2. The four types of GST — CGST, SGST, IGST, UTGST

India runs a "dual GST" system. When you sell something, there's always tax going to the Centre and tax going to the State — but the way it splits depends on where the buyer is.

2.1 CGST — Central GST

Charged by the Central Government on every intra-state supply. Half of the total GST rate. If you're selling a laptop at 18% GST inside Maharashtra, 9% goes to the Centre as CGST.

2.2 SGST — State GST

The other half of every intra-state supply, collected by the State Government. Continuing the laptop example: 9% goes to Maharashtra as SGST. CGST and SGST are always equal — never one higher than the other.

2.3 IGST — Integrated GST

Charged when the supply is inter-state. Your business in Delhi ships that same laptop to a buyer in Kerala — you charge 18% IGST. All of it goes to the Centre first, which then transfers the state portion to Kerala (the "destination" state). From the invoice-writing perspective, you just charge one line: IGST 18%.

2.4 UTGST — Union Territory GST

Same as SGST, but for Union Territories that don't have a legislature — Andaman & Nicobar, Chandigarh, Dadra & Nagar Haveli, Daman & Diu, Lakshadweep, and Ladakh. So a supply within Chandigarh is CGST + UTGST. Delhi, Puducherry and J&K have legislatures, so they use CGST + SGST like states.

3. Every GST slab in 2026 (with real examples)

India's GST Council meets every few months and tweaks rates. As of the latest revision, the effective slab structure looks like this:

Real quick — a common confusion. "0%" and "exempt" are not the same. A 0% supply (like exports) still lets you claim ITC on your inputs. An exempt supply (like fresh milk) does not. The result on the customer invoice looks identical, but the ITC treatment on your side is completely different.

Where our GST calculator fits in

The tool above supports all five main slabs (5%, 12%, 18%, 28%) with a custom rate field for edge cases (3%, 0.25%, 12.5%, cess add-ons). Pick your slab, drop in the amount, and it computes CGST+SGST or IGST depending on the supply type toggle.

4. GST formulas — add GST, remove GST, reverse calculation

Three formulas cover ninety-nine percent of what you'll ever need.

4.1 Adding GST to a base amount

You know the pre-tax price. You want the final invoice value.

4.2 Removing GST from a GST-inclusive amount (reverse GST)

The customer paid you a lump-sum that already includes GST. You need to split it into base + tax for your books.

4.3 GST on a discount

Discounts that are known before or at the time of supply — and are shown on the invoice — reduce the taxable value. Discounts announced after supply (e.g. a year-end volume rebate) can also reduce taxable value only if there's a pre-existing agreement and both parties reverse the corresponding ITC.

4.4 GST when the tax is embedded (B2C retail)

Most retailers quote MRP-inclusive prices. If your kirana bill totals ₹500 and everything's at 12%, the base is 500 ÷ 1.12 = ₹446.43 and GST is ₹53.57. This is where the reverse formula becomes daily bread.

5. GST inclusive vs exclusive pricing — which one to quote?

Big decision. If you're B2B (invoicing another business), always quote exclusive of GST. Your client can claim the tax back as ITC, so making it a separate line is transparent and expected. If you quote inclusive of GST to a B2B client, they'll assume the sticker price is your rate and complain when you split it later.

If you're B2C (selling to end consumers), inclusive pricing usually wins. Customers hate seeing a "final total" go up by 18% at checkout. Amazon, Flipkart, Zomato — they all show inclusive-of-tax prices on the listing.

Here's the compromise most agencies use in India: quote both. On your proposal, write "Fees: ₹50,000 (excluding applicable GST at 18% — ₹9,000, payable extra)". No ambiguity, no surprise, no email back-and-forth two weeks later.

Our free quotation generator lets you choose "GST-inclusive" or "GST-exclusive" per quotation, and prints both the taxable and total value clearly on the PDF. Zero confusion for the buyer.

6. Intra-state vs inter-state — the "place of supply" trap

The single most common mistake we see, especially with service businesses, is charging the wrong type of GST because they got confused between "billing address" and "place of supply". These are not the same thing.

For goods:

Place of supply is where the goods are delivered. Simple. You're in Delhi, shipping to a warehouse in Gurgaon (Haryana) — that's inter-state. Bill IGST.

For services:

Default rule: place of supply is the location of the recipient if the recipient is a registered business (uses their GSTIN address). If the recipient is unregistered, it's their address on record; and if that's not available, then the supplier's location.

There are exceptions — services related to immovable property (place of supply = location of the property), transport of passengers (place where the passenger boards), telecom services (billing address), and a bunch of others under Section 12/13 of the IGST Act.

7. HSN & SAC codes — the classification maze

Every invoice line item needs a code that tells the tax authorities what kind of goods or service you're selling. Goods use HSN (Harmonized System of Nomenclature) — a 6-to-8-digit international code. Services use SAC (Services Accounting Code) — 6 digits, prefixed with 99.

HSN digit requirements:

• Aggregate turnover up to ₹5 crore: 4-digit HSN mandatory (for B2B), optional for B2C
• Aggregate turnover above ₹5 crore: 6-digit HSN mandatory
• Exports/imports: always 8-digit HSN

Common HSN codes small businesses look up:

Common SAC codes:

The full CBIC HSN/SAC finder is at cbic-gst.gov.in — bookmark it. If you're unsure, don't guess; check with your accountant. Using the wrong code can trigger a Section 65 audit notice.

8. Regular vs composition scheme

Composition scheme is designed for small businesses that don't want the compliance load of monthly returns and full ITC tracking. If your annual turnover is under ₹1.5 crore (₹75 lakh in special-category states), you can opt in.

What you pay under composition:

• Manufacturers: 1% (0.5% CGST + 0.5% SGST) of turnover
• Traders: 1% (0.5% CGST + 0.5% SGST) of turnover
• Restaurants (non-alcoholic): 5% (2.5% CGST + 2.5% SGST) of turnover
• Services (up to ₹50 lakh): 6% (3% CGST + 3% SGST) of turnover

What you give up:

• Cannot claim Input Tax Credit
• Cannot charge GST on invoices (must issue "Bill of Supply" instead)
• Cannot make inter-state outward supplies
• Cannot sell through e-commerce operators (like Amazon, Flipkart)

Verdict: composition works great for a neighbourhood kirana, a small restaurant that mainly serves walk-ins, a manufacturer selling to unregistered end-users. It's terrible for a B2B service business, because your corporate clients need the GST invoice for their own ITC and you can't provide one.

9. Input Tax Credit — the reason GST exists

Say you buy raw materials for ₹1,00,000 + 18% GST = ₹18,000 tax paid to your supplier. You then process those materials into finished goods and sell them for ₹1,50,000 + 18% = ₹27,000 GST collected from your customer.

Under pre-GST tax law (VAT), you'd owe the government ₹27,000. Under GST, you owe the government only the difference — ₹27,000 minus the ₹18,000 you already paid — that's ₹9,000. The ₹18,000 you paid to your supplier is Input Tax Credit; you claim it as an offset.

This is why every business chases GST invoices from vendors. Every ₹100 of unclaimed ITC is ₹100 of extra tax cost.

Conditions for claiming ITC:

1. You must hold a valid tax invoice
2. You must have actually received the goods/services
3. The supplier must have paid the GST to the government (this is what makes GSTR-2A/2B matching critical)
4. You must have filed your GSTR-3B for the tax period
5. The purchase must be for business use (personal use = no ITC)

10. Fifteen real industry examples with numbers

Numbers make everything click. Here are fifteen scenarios we've built real invoices for. Amounts are illustrative but the calculation logic is exactly how it works.

Example 1 — Freelance UI designer, Bengaluru → Delhi client

Project fee ₹80,000. Both parties registered under GST. Since it's inter-state (Karnataka → Delhi), charge IGST at 18% on the design service.

Invoice: Base ₹80,000 + IGST 18% ₹14,400 = ₹94,400. The Delhi client claims ₹14,400 as ITC on their books.

Example 2 — Restaurant in Pune, dine-in bill

Food ₹1,200. Non-AC standalone restaurant, GST 5% (no ITC available to restaurant on this side).

Bill: Base ₹1,200 + CGST 2.5% ₹30 + SGST 2.5% ₹30 = ₹1,260.

Example 3 — SaaS subscription, Chennai company → Mumbai customer

Monthly subscription ₹5,000. SAC 998314 (software services), 18%. Inter-state.

Invoice: ₹5,000 + IGST ₹900 = ₹5,900.

Example 4 — Manufacturer selling AC units to a retailer in the same state (Haryana)

Wholesale price per AC ₹35,000, qty 10 = ₹3,50,000. GST rate 28%. Intra-state.

Invoice: ₹3,50,000 + CGST 14% ₹49,000 + SGST 14% ₹49,000 = ₹4,48,000.

Example 5 — Rent from a commercial office (Kolkata landlord → Kolkata tenant)

Monthly rent ₹40,000. Rent of commercial property, SAC 997212, GST 18%. Intra-state (both in West Bengal).

Invoice: ₹40,000 + CGST 9% ₹3,600 + SGST 9% ₹3,600 = ₹47,200.

Example 6 — Export of IT services to a US client

Export of services is a zero-rated supply — GST rate is 0%, but you can still claim full ITC on your inputs. You issue an invoice in foreign currency, mention "Supply meant for export under LUT — no IGST payable".

Invoice: USD 5,000 (no GST). File LUT once a year to keep this option open.

Example 7 — E-commerce seller on Amazon, Delhi → Bengaluru buyer

Product sale ₹2,000 (before GST), GST 18%, inter-state.

Invoice: ₹2,000 + IGST ₹360 = ₹2,360. Amazon collects TCS 1% on the taxable value (₹20). Seller can claim that TCS back as ITC.

Example 8 — Photographer in Ahmedabad shooting a wedding in Udaipur (Rajasthan)

Wedding photography services, SAC 998387, 18%. This is service related to an event; place of supply is where the event happens — Udaipur, Rajasthan. So inter-state, IGST 18%.

Invoice: ₹80,000 + IGST ₹14,400 = ₹94,400.

Example 9 — Composition scheme kirana in Jaipur

Monthly turnover ₹3,00,000. Composition trader rate 1%. GST liability = ₹3,000 (₹1,500 CGST + ₹1,500 SGST). Kirana does not collect this from customers — pays it out of pocket. Bills to customers are "Bill of Supply", no GST charged.

Example 10 — Chartered Accountant firm, Hyderabad → local client

Audit fees ₹1,25,000. SAC 998222, 18%. Intra-state.

Invoice: ₹1,25,000 + CGST 9% ₹11,250 + SGST 9% ₹11,250 = ₹1,47,500.

Example 11 — Gym membership, Noida branch → local resident

Annual membership ₹18,000. SAC 999723, 18%. Intra-state (both UP).

Bill: ₹18,000 + CGST ₹1,620 + SGST ₹1,620 = ₹21,240. Individual paying can't claim ITC (personal use).

Example 12 — Freight/transporter charging on a full truckload

Base freight ₹25,000, road transport by GTA under forward charge, GST 5% (with ITC) or 12% (without ITC). If GTA opts for 12% forward charge:

Invoice: ₹25,000 + IGST 12% ₹3,000 = ₹28,000. If reverse charge applies (5%), the recipient pays GST directly to the government.

Example 13 — Small hotel in Goa, room tariff ₹4,500/night

Declared tariff ₹4,500 (below ₹7,500). GST 12%. Intra-state.

Bill: ₹4,500 + CGST 6% ₹270 + SGST 6% ₹270 = ₹5,040.

Example 14 — Digital marketing agency, Bengaluru → Bengaluru client

Monthly retainer ₹75,000. SAC 998361, 18%, intra-state.

Invoice: ₹75,000 + CGST ₹6,750 + SGST ₹6,750 = ₹88,500.

Example 15 — Cross-charge between branches (Chennai HQ → Mumbai branch, same PAN)

Support services allocated ₹5,00,000/month. Even though same company, they have separate GSTINs in different states. So this is an inter-branch supply, IGST at 18% applies as a "distinct persons" transaction under Section 25(4).

Cross-charge invoice: ₹5,00,000 + IGST ₹90,000 = ₹5,90,000. The receiving branch takes the ₹90,000 as ITC.

11. Nine common GST calculation mistakes we see every month

1. Rounding at the item level, then summing. GST invoices should show the total taxable value first, then compute GST on the sum, then round. Rounding each line and summing can create ₹1-2 mismatches with your customer's ERP.
2. Using MRP as taxable value on B2B invoices. MRP is the maximum retail price meant for end consumers; between businesses, you invoice at the negotiated wholesale/discounted price.
3. Charging CGST+SGST on inter-state supplies (or IGST on intra-state). Costs the recipient their ITC until you reissue. Costly for both sides.
4. Ignoring the reverse charge mechanism (RCM). Certain services — legal, GTA, security services from unregistered suppliers, sponsorship — trigger RCM. You self-invoice and pay GST yourself. Missing this is a Section 74 issue.
5. Missing e-invoicing threshold. B2B businesses with turnover above ₹5 crore must generate e-invoices with IRN before issuing physical invoices. This threshold has been dropping year-on-year. Check the latest.
6. Charging GST on exempt or nil-rated supplies. If your service is exempt (like educational services by a school), you cannot charge GST. Charging it and depositing to the government is fine, but the customer can't claim ITC.
7. Assuming all supplies to SEZ are zero-rated automatically. Supplies to SEZ are zero-rated only if covered by LUT or paid IGST that's later refunded. Regular tax invoice with IGST is not the correct treatment.
8. Not adding cess where applicable. Compensation cess is over and above the 28% GST slab on certain sin/luxury goods (tobacco, aerated drinks, motor vehicles, coal). If you're selling any of these, add the cess line separately.
9. Confusing "taxable value" with "gross value". Taxable value = value after subtracting discounts shown on invoice, but including packing, freight, insurance charged to buyer. Getting this wrong is the top reason for GSTR-1 vs GSTR-3B mismatches.

12. GST for exporters, importers & SEZ suppliers

Cross-border transactions have their own quirks that trip up a lot of Indian SMBs the first time they try it. Let me walk through the three main scenarios.

12.1 Export of goods or services (zero-rated supply)

Under Section 16 of the IGST Act, exports are zero-rated. Two options for the exporter:

1. Option A — Export under LUT (Letter of Undertaking): Furnish a one-time LUT at the start of the financial year, and export without paying IGST. Claim ITC refund on inputs. This is the option 95% of IT exporters and consulting firms pick.
2. Option B — Pay IGST at the time of export and claim refund later: Cash-flow negative because you park capital with the government for 60-90 days. Rarely used unless the exporter can't obtain LUT (which basically doesn't happen for compliant taxpayers).

For an IT services export, the invoice mentions "Supply meant for export under LUT — no IGST payable" and the amount is in the client's foreign currency. FIRC/FIRA from the bank is the proof of realisation you'll need at filing.

12.2 Import of goods

Imports attract IGST + basic customs duty + Social Welfare Surcharge. The IGST portion is available as ITC, so it flows through your books. Basic customs duty and SWS are pure cost.

12.3 Import of services

Under reverse charge, the recipient in India pays GST on imports of services. Example: You subscribe to a US SaaS tool for $500/month. You must self-invoice at 18% IGST on the INR equivalent and pay it in your next GSTR-3B. You can claim it back as ITC in the same return (self-neutralising, but the paperwork must exist).

13. E-invoicing — do you need it?

E-invoicing is mandatory for B2B invoices if your aggregate annual turnover crossed a certain threshold in any preceding financial year. As of the latest notification, that threshold sits at ₹5 crore. It has come down steadily: ₹500 crore → ₹100 crore → ₹50 crore → ₹20 crore → ₹10 crore → ₹5 crore. Expect it to drop further.

Under e-invoicing, you submit invoice details to the government's Invoice Registration Portal (IRP) before issuing the invoice to your customer. The IRP validates the payload and returns an Invoice Reference Number (IRN) + a signed QR code. Both must appear on the invoice you actually send.

What e-invoicing does not mean:

• It doesn't file GSTR-1 automatically for you (auto-populates, but you still verify and submit)
• It doesn't apply to B2C invoices below ₹5 crore turnover threshold
• It doesn't cover exports below the threshold either

14. GST on services vs goods — five key differences

1. Place of supply rules differ. Goods = location of delivery. Services = default location of recipient (with several exceptions).
2. Time of supply differs. Goods = date of invoice or removal, whichever earlier. Services = date of invoice or receipt of payment, whichever earlier.
3. Reverse charge scope differs. Many services (legal from advocates, GTA, sponsorship, insurance agents) attract RCM. Very few goods do.
4. Composition threshold differs. Services under composition have a ₹50 lakh cap at 6%. Goods composition allows ₹1.5 crore at 1%.
5. HSN vs SAC. Goods have 4-8 digit HSN codes. Services have 6-digit SAC codes prefixed with 99. Getting this wrong on your GSTR-1 leads to reconciliation issues.

15. Deep dive — GST for the Indian freelancer

We get a lot of "should I register for GST?" questions from freelancers. Here's the full decision tree we walk them through.

Step 1 — What's your annual gross receipts likely to be?

Under ₹20 lakh (₹10 lakh in Manipur, Mizoram, Nagaland, Tripura and some north-eastern states)? Registration is optional. Above? Mandatory.

Step 2 — Do you have Indian corporate clients?

If yes, they'll usually ask for your GSTIN. Reason: without a GST invoice from you, they can't claim ITC on your fees. Not having a GSTIN means they may still work with you but at a lower rate (because effectively you cost them 18% more than a GST-registered peer). If your Indian client base is significant, register even if turnover is under the threshold.

Step 3 — Are you exporting?

Export receipts count toward the ₹20 lakh threshold. Even if your entire revenue is from foreign clients, once you cross ₹20 lakh, register. Once registered, you file LUT once a year and export without paying GST — plus you get ITC refunds on your business expenses (co-working, laptop, software subscriptions, etc.).

Step 4 — Are you supplying via e-commerce platforms?

Selling design services on Fiverr / Upwork / Toptal that have Indian entities? Selling products via Amazon, Flipkart? Registration is mandatory from ₹1 (no threshold benefit) — because e-commerce operators need to collect TCS on your supplies.

Step 5 — Composition or regular?

For a service freelancer earning up to ₹50 lakh a year, composition at 6% flat sounds attractive. But — you can't claim ITC, can't do inter-state, can't do e-commerce. For most freelancers, regular scheme + LUT for exports + monthly QRMP for domestic is the sweet spot.

Freelancer GST checklist (once registered)

• Add your GSTIN to every invoice + on your website's footer
• File LUT in Form GST RFD-11 at the start of every financial year (if exporting)
• Opt into the QRMP scheme (quarterly filing, monthly payment) if turnover under ₹5 crore
• File GSTR-1 (outward supplies) and GSTR-3B (summary + payment) — QRMP simplifies both
• Reconcile GSTR-2B (auto-populated ITC) against your purchase invoices every month
• Keep books of accounts for at least 72 months from the due date of the annual return

13. Who uses this calculator (and how)

Six user profiles show up in our analytics again and again:

Freelancers & consultants

Quick check before sending a WhatsApp quote: "₹35,000 kis rate pe kitna hoga?". They copy the total and paste it into the conversation. Time saved per day: ten to fifteen minutes.

Small business owners

Verifying supplier invoices. Vendor sends a bill; owner cross-checks the GST split against our calculator before approving payment. Catches vendor calculation errors before money moves.

Accountants & CAs

Reverse GST calculations during reconciliation. Client shares bank statement entries with lump-sum credits; CA extracts the taxable value and GST portion for GSTR-1 reporting.

Retailers & kirana owners

Working backwards from MRP to figure out margin. If MRP is ₹500 including 12% GST, base is ₹446.43 — margin comes off the base, not the MRP.

Students studying commerce, CA/CS/CMA

Practice numerical problems, verify textbook answers, cross-check exam solutions.

E-commerce sellers

Setting listing prices. Amazon takes MRP-inclusive prices; sellers use reverse GST to know their actual margin after platform commission and tax.

14. Frequently asked questions

Is this GST calculator accurate for 2026?

Yes. It uses the GST rates and CGST/SGST split logic notified by the GST Council up to the current date. If the Council revises a slab, we update within 24 hours.

Can I calculate GST on multiple items at once?

This calculator handles one line at a time — perfect for quick lookups. For multi-line invoices with different GST rates per item, use our invoice generator instead; it handles mixed rates automatically.

Does the tool work offline?

Once the page has loaded, yes — everything runs in your browser. You can bookmark the page and use it even when your internet drops.

What about GST on freight or packing charges?

Freight and packing charged to the buyer are part of the taxable value and attract the same GST rate as the underlying goods. So if the goods are 18%, freight on the same invoice is also 18%. If freight is paid separately to a Goods Transport Agency (GTA), a different rate (usually 5% under RCM or 12% under forward charge) applies.

How do I calculate GST on a discounted price?

Take the discounted price as the taxable value. Example: MRP ₹1,000, 20% discount = ₹800 taxable. GST 18% on ₹800 = ₹144. Total invoice ₹944.

Do I charge GST on advance payment?

For goods, no — GST on advance was withdrawn for goods in November 2017. For services, yes — GST is payable at the time of advance receipt. You need to issue a receipt voucher and adjust when the final invoice is issued.

Can our calculator handle the cess on cars, tobacco?

Cess isn't a preset slab in our tool. Calculate GST at 28% first, then add cess manually (e.g. 15%–22% on cars, 12%–36% on tobacco depending on category). We may add a dedicated cess field in a future update.

Is my data safe? Do you store what I calculate?

Nothing is stored on our servers. Everything happens in your browser. You can open DevTools and confirm — no outbound network requests are made when you type numbers into the tool.

How is this different from Zoho's or ClearTax's GST calculator?

Three things: (1) no sign-up wall, (2) supports both add-GST and remove-GST in one interface, (3) shows the CGST + SGST split by default so you can copy the exact split into your accounting software. Also — no ads.

Can I use this for filing GSTR-1 or GSTR-3B?

Directly, no — filing needs invoice-level upload. But the numbers this tool gives you are exactly the values you'll enter in the invoice-level rows of GSTR-1. Use it as a spot-check tool during return preparation.

If you spot an error in the guide, or a scenario we didn't cover, drop us a line via the contact page. We update this page whenever the GST Council changes a rate or clarifies a rule.
