GST Exclusive Calculator
Add GST to a price quoted exclusive of tax to get the final amount payable.
What is the GST Exclusive Calculator?
Business quotes are usually exclusive of GST (“+ GST”). The buyer pays the price plus GST.
How does it work?
GST = price × rate ÷ 100, and the total is price + GST.
Formula
Total = Price × (1 + Rate ÷ 100)
Example
₹25,000 + 18% GST = ₹29,500.
Frequently asked questions
What are the current GST rates?
Since 22 September 2025, most goods and services fall under 5% or 18%, with 40% for luxury and sin goods. Special rates of 0.25% and 3% apply to precious stones and metals. The 12% and 28% slabs remain selectable for older invoices.
When is IGST charged instead of CGST + SGST?
IGST applies when the supplier and the place of supply are in different states (and on imports). For supplies within the same state, the rate is split equally into CGST and SGST (or UTGST in union territories).
