GST Calculator

Goods and Services Tax (GST) is applied to most goods and services sold in India, at rates set by the government for each category. This calculator helps you move quickly between a base amount and a GST-inclusive amount, without doing the maths by hand.

How this calculator works

Choose whether you're adding GST to a base amount or extracting it from a total that already includes tax, enter the applicable GST rate, and the calculator shows the tax amount, the resulting total, and the CGST/SGST split for an intra-state supply.

A few things worth knowing

The applicable GST rate depends on the specific goods or service — always confirm the correct rate for your transaction with your accountant or the relevant GST notification, especially for anything filed with the tax department. This tool is a quick reckoner, not a substitute for professional tax advice.
