GST, VAT and sales tax are taxes added to the price of goods and services. To add tax you multiply the price by the rate. To remove tax from a total, you divide the total by one plus the rate. This calculator does both and shows the tax amount clearly.
How to use it
- Enter the amount.
- Choose whether it is without tax (add tax) or with tax included (remove tax).
- Enter your tax rate or tap a common rate.
- For Indian GST, choose CGST + SGST for sales within the same state, or IGST for sales to another state.
- Read the result and press Copy result.
Tips
Tax rates differ by country and by item, and they can change. Always check the rate that applies to your goods or services with your tax authority or accountant. The calculator uses only the rate you type.
Frequently asked questions
How do I calculate GST from a tax-inclusive price?
Divide the total by (1 + rate ÷ 100) to get the price before tax. The difference is the tax. For 18%, divide by 1.18.
What are CGST, SGST and IGST?
In India, a sale within one state charges CGST and SGST, each half of the GST rate. A sale to another state charges IGST at the full rate.
Which GST rate should I use?
This tool does not decide that. Use the rate your goods or services fall under, as published by the tax authority.
Does this work for VAT in other countries?
Yes. Rename the tax to VAT and enter your local rate. The maths is the same.
