How the calculation works

For a pre-GST amount, the GST component equals base amount × entered rate. For an inclusive bill, the pre-GST amount equals inclusive total ÷ (1 + GST rate), and the GST component is the difference.

How to use the result

Use the tool to check bill arithmetic or to extract the tax component from an inclusive menu or package price. Always enter the rate that has been verified for the restaurant's actual supply and tax position.

Assumptions and limitations

Restaurant GST treatment can depend on the type of establishment, location, supply and current tax rules. Service charges, discounts and other bill components may have separate treatment. This tool does not determine eligibility, input-tax-credit treatment or filing obligations.

Example

At a 5% entered rate, a ₹2,000 pre-GST amount produces ₹100 GST and a ₹2,100 inclusive total.

Frequently asked questions

Does this tool decide whether 5% or another rate applies?

No. The rate is editable because the correct treatment must be verified for the actual supply.

Can it extract GST from an inclusive menu price?

Yes. Choose GST included and enter the verified GST rate.

Does it include service charge?

Only if the amount you enter already contains the bill components you want to calculate on.

Is this a GST compliance tool?

No. It provides arithmetic only and does not replace tax verification or filing software.
