This GST calculator helps you quickly compute tax amounts for goods or services in India. You can calculate GST in both Exclusive and Inclusive modes with automatic breakdown into CGST, SGST, or IGST.

The calculator updates results instantly as you type, making it useful for billing, invoicing, price planning, and tax estimation.

GST Calculation Examples

Example 1 (Exclusive):
Amount ₹1,000 with 18% GST → GST ₹180 → Total ₹1,180

Example 2 (Inclusive):
Total ₹1,180 including 18% GST → Base ₹1,000 → GST ₹180

Example 3 (Interstate):
IGST is applied instead of CGST + SGST for interstate transactions.

How Is This Different from Other GST Calculators?

Most basic GST calculators only add or subtract a percentage. This calculator is built specifically for the Indian GST ecosystem.

Situations & Live Examples

Scenario A: Freelancer’s Quote (Exclusive GST)

A designer charges ₹5,000 for a logo and applies 18% GST.
Result: Base ₹5,000 | GST ₹900 | Total ₹5,900

Scenario B: Shopkeeper’s MRP (Inclusive GST)

A jacket is sold at MRP ₹5,000 including 18% GST.
Result: Base ₹4,237.29 | GST ₹762.71

This prevents businesses from overpaying GST by calculating tax incorrectly on inclusive prices.
