When a price tag says "โ‚น1,180 (GST inclusive)," what did the actual product cost before tax? Our GST inclusive calculator instantly reverse-calculates the base price and the exact GST amount from any GST-included total โ€” essential for invoicing, accounting, and consumer clarity in India.

What is a GST Inclusive Calculator?

A GST inclusive calculator works backwards from a tax-included price to find the original base price and the GST component separately. This is used by businesses for accurate bookkeeping (where input tax credit is claimed on the base price), by consumers verifying receipts, and by e-commerce sellers calculating their actual product revenue after GST is removed.

Formula

Base Price = GST-Inclusive Amount รท (1 + GST Rate/100)

GST Amount = GST-Inclusive Amount โˆ’ Base Price

Example Calculation

You received โ‚น1,180 for a product sold with 18% GST included in the price.

  • Base Price = โ‚น1,180 / (1 + 18/100) = โ‚น1,180 / 1.18 = โ‚น1,000
  • GST Amount = โ‚น1,180 โˆ’ โ‚น1,000 = โ‚น180
  • CGST (9%) = โ‚น90 | SGST (9%) = โ‚น90

How to Use This Calculator

  1. Enter the GST-Inclusive Amount (the final price the customer paid).
  2. Select the GST Rate applicable (5%, 12%, 18%, or 28%).
  3. Click Calculate to instantly see the base price, GST amount, and CGST/SGST split.

Real Life Use Cases

  • E-commerce Sellers: On platforms like Amazon/Flipkart, the customer pays a GST-inclusive price. This tool extracts your actual product revenue.
  • Input Tax Credit (ITC): Businesses can claim ITC only on the base price. This calculator identifies the exact claimable amount.

  • Accounting: Post separate base price and GST amounts to the correct ledger accounts.
