About the GST Calculator
GST (Goods and Services Tax) is added to the price of most goods and services in India. This calculator adds GST to a base price, or removes it from a GST-inclusive price.
Choose the mode, enter the amount and the GST rate.
Formula used
Add GST: total = amount × (1 + rate/100). Remove GST: net = amount ÷ (1 + rate/100).
Frequently asked questions
How do I find the GST rate?
It depends on the product or service. Check the invoice or the official GST rate list, as rates are revised from time to time.
What are CGST and SGST?
For sales within a state, the GST is split equally into CGST and SGST. For interstate sales, IGST applies.
How do I calculate GST from an inclusive price?
Use "Remove GST" mode. It divides the price by (1 + rate/100).
