Calculate GST for any amount — exclusive or inclusive — with CGST & SGST breakdown.
Goods and Services Tax (GST) is an indirect tax used in India. It replaced multiple cascading taxes and is applied at rates of 0%, 5%, 12%, 18%, or 28%.
Exclusive: GST is added on top of the price (e.g., price ₹1000 + 18% GST = ₹1180). Inclusive: GST is already included in the stated price.
For intra-state transactions, GST is split equally into CGST (Central) and SGST (State). For inter-state, it's charged as IGST (Integrated).
This GST calculator helps you work out tax-inclusive and tax-exclusive prices without opening a spreadsheet or doing reverse calculations by hand. Enter the amount, choose the GST slab, and switch between exclusive and inclusive pricing to see the base amount, GST amount, and final total instantly. The breakdown is useful when preparing invoices, checking vendor quotes, reviewing online selling prices, or confirming how much tax is included in a final bill.
It works well for freelancers, agencies, accountants, small businesses, and shoppers who want a quick answer before creating a quotation or invoice. If you also need to compare discounts or total repayment costs, the Percentage Calculator, Loan Calculator, and Currency Converter are good next steps.
Add 18% GST to a service invoice, extract 12% GST from a tax-inclusive product price, or compare base value versus total selling price before sending a customer quote.
You do not need to remember separate formulas for exclusive and inclusive tax calculations. The page handles the math and displays the result clearly for faster checks.
The calculator supports the common GST slabs used in India, including 0%, 5%, 12%, 18%, and 28%, which covers many everyday goods and service scenarios.

Multiply the amount by the GST rate and add that tax value to the original price.
How do I remove GST from an inclusive amount?
Select the inclusive option and the tool separates the original base amount from the GST portion automatically.
What is the difference between CGST, SGST, and IGST?
CGST and SGST are typically used for intra-state transactions, while IGST applies to inter-state transactions.
