Add or remove GST on any amount using the 2026 slabs, split it into CGST/SGST or IGST, and check what a marketplace order actually pays you after commission and TCS. Free, no sign-up, and nothing leaves your browser.
Enter an amount, pick the rate, and choose whether GST still has to be added or is already inside the price.
Amazon, Flipkart and Meesho don't hand you the full order value. This strips out commission (and the 18% GST charged on that commission) and the 0.5% TCS they deposit against your GSTIN.
An estimate, not a settlement statement. Every platform has its own fee names — closing fee, fixed fee, weight-handling, ad spend — and rate cards differ by category. Use your own settlement report for the exact figure.
Upload your Amazon, Flipkart or Meesho report and get a portal-ready GSTR-1 JSON in about two minutes. The sales summary is free.
Try the GSTR-1 tool →There are only two formulas, and which one you need depends on whether the price you are looking at already contains the tax.
Adding GST to a taxable value: GST = value × rate ÷ 100. A ₹1,000 item at 5% carries ₹50 of GST, so the invoice total is ₹1,050.
Removing GST from an inclusive price: taxable value = price × 100 ÷ (100 + rate). This is the one online sellers need most, because a marketplace listing price of ₹1,050 is inclusive — the taxable value hiding inside it is ₹1,000 and the GST is ₹50. Getting this backwards is the single most common reason a GSTR-1 doesn't match the settlement report.
The 56th GST Council meeting on 3 September 2025 replaced the old four-slab system. From 22 September 2025 the structure is simpler: most goods sit at 5% or 18%, and a new 40% rate covers luxury and sin goods.
| Rate | Typically covers |
|---|---|
| 0% | Essentials — unbranded food grains, fresh produce, and other exempt or nil-rated supplies |
| 5% | Everyday and priority goods, including a large share of what was previously taxed at 12% |
| 18% | The standard rate for most goods and services, including much of the old 28% slab |
| 40% | Luxury and sin goods — pan masala, tobacco, aerated and caffeinated drinks, high-end vehicles |
The 12% and 28% slabs were largely withdrawn, but they remain in the calculator above because you will still meet them in older invoices, credit notes and amendments for periods before September 2025.
Rates are item-specific and change with Council notifications. Always confirm the rate for your exact HSN code on the CBIC rate finder before you file. This page explains the arithmetic, not the classification.
The total tax never changes; only the labels do. If the place of supply is inside your own state, the tax is split down the middle into CGST (central) and SGST (state) — 5% becomes 2.5% + 2.5%. If the buyer is in another state, the entire 5% is charged as IGST.
For marketplace sellers this is decided by the customer's delivery pin code, which is why a single day's orders will contain both kinds. Your GSTR-1 has to report them separately, and B2C inter-state sales above the threshold need a state-wise break-up.
Under section 52 of the CGST Act, every e-commerce operator collects tax at source on the sales you make through it. The rate was cut from 1% to 0.5% with effect from 10 July 2024, and it is charged on the net value of taxable supplies — your sales minus returns, excluding GST itself.
On an intra-state order it appears as 0.25% CGST plus 0.25% SGST; on an inter-state order, as 0.5% IGST. The money is not lost. The operator files GSTR-8 and the amount lands in your electronic cash ledger, where you can use it against your own liability or claim it as a refund. What you do have to do is check it — the TCS credit auto-populating in your return should reconcile with what the platform actually deducted.
To add GST, multiply by the rate: value × rate ÷ 100. To pull GST out of a price that already includes it, divide: price × 100 ÷ (100 + rate). The calculator at the top does both — just switch the toggle.
0%, 5%, 18% and 40%, in force since 22 September 2025. The old 12% and 28% slabs were largely folded into 5% and 18%.
Same state as the buyer means CGST + SGST, split equally. Different state means IGST at the full rate. The total tax is identical either way.
0.5% of the net taxable value of your sales, after returns and excluding GST. You get it back as credit in your electronic cash ledger once the platform files its GSTR-8.
Yes, and there is no sign-up. The maths runs entirely in your browser — nothing you type is sent anywhere.
