GST formulas

Add GST: GST amount = Net price × rate ÷ 100. Total = Net price + GST amount.

Remove GST: Net price = Total ÷ (1 + rate ÷ 100). GST amount = Total − Net price.

For sales within a state, GST is split equally into CGST (centre) and SGST (state). For sales between states, the whole amount is charged as IGST.

Frequently asked questions

What are the current GST rates in India?

Since 22 September 2025 most goods and services fall under the 5% or 18% slab, with 40% on certain luxury and sin goods. A few special rates such as 0.25% and 3% remain, and some items are exempt (0%). The older 12% and 28% slabs are available under "Show old rates" for past invoices.

How do I calculate GST from a GST-inclusive price?

Choose "Remove GST", enter the total price and pick the rate. The calculator divides by (1 + rate) to give the net price and the GST included.

What is the difference between CGST, SGST and IGST?

CGST and SGST apply to sales within the same state and each is half of the GST rate. IGST applies to sales between states or from abroad and equals the full rate.

Which rate applies to my product or service?

That depends on its HSN or SAC code. Check the official GST rate schedule or ask your tax adviser, then enter that rate here.

Is this a replacement for GST filing software?

No. It is a quick calculator for estimates and simple invoices. Use proper accounting software and a registered tax professional for filing and compliance.
