Add as many line items as you need, price them inclusive or exclusive of tax, and get the exact CGST/SGST or IGST split, cess, round-off and rate-wise summary. Free, instant, no sign-up.
Intra-state supplies split into CGST and SGST; inter-state supplies carry a single IGST at the same total rate. Your rate depends on the classification of what you sell, look it up in the HSN / SAC finder. Indicative only, confirm with an Expert before you file.
Most calculators handle one amount at one rate. This one handles a whole invoice: several items on different slabs, discounts, compensation cess, reverse charge and the deductions that decide what actually lands in your bank.
This calculator gives you the right numbers for a single transaction. But staying compliant means doing it for every invoice, reconciling input credit, and filing GSTR-1 and GSTR-3B on time, month after month.
Our GST Return Filing service does exactly that, your dedicated Expert prepares, reconciles and files your returns so you never miss a deadline or a credit.
Done-for-you monthly filing by a real Expert, from a fixed monthly fee.
For a sale within the same state, GST is split equally into CGST (central) and SGST (state). For inter-state sales, a single IGST is charged at the full rate instead. Switch “Place of supply” to see either split, the total tax is identical.
The rate depends on the HSN (goods) or SAC (services) classification of what you sell, commonly 5%, 12%, 18% or 28%. The calculator also carries the special rates: 0.1% for merchant exports, 0.25% for rough diamonds, 1% and 5% for real estate, 3% for gold. Use our HSN/SAC finder to look yours up.
MRP is already inclusive of GST. Set “Amount you enter is” to Incl. GST and the calculator backs out the taxable value and the tax component hidden inside it.
Cess is an extra levy on top of GST on demerit and luxury goods: cars, tobacco, pan masala and aerated drinks. Rates run from 1% to 22% and higher on tobacco. Enter it per line and it is calculated on the taxable value, not on the GST.
A discount shown on the face of the invoice reduces the taxable value, so tax is charged on the net amount. Post-sale discounts only reduce it if they were agreed before the supply and are linked to the invoice. Enter yours as a percentage, or switch to flat rupees in advanced options.
On certain supplies, including goods transport, legal services and purchases from unregistered dealers, the recipient pays the GST instead of the supplier. Turn on RCM and the invoice bills the taxable value only, with the tax shown separately as the recipient’s liability.
Section 170 of the CGST Act rounds the tax and the total to the nearest rupee. The calculator shows the round-off as its own line so your invoice ties out exactly. Turn it off in advanced options if you need the paise.
Government departments and PSUs deduct 2% TDS under section 51 on contracts above ₹2.5 lakh. E-commerce operators collect 0.5% TCS under section 52 on your net taxable sales — halved from 1% by Notification 15/2024-Central Tax with effect from 10 July 2024. Both are computed on the taxable value, not on the tax, and both land in your electronic cash ledger to offset later liability.
