About the Sales Tax Calculator

This calculator computes GST or sales tax on any transaction amount and shows the total payable. You enter a price and a tax rate, and it returns the tax value, the net amount, and the gross total. It works for both tax-exclusive and tax-inclusive prices.

The tool applies the standard percentage method used on Indian invoices. For a tax-exclusive price, it calculates tax as the amount multiplied by the rate divided by 100, then adds that tax to the base. For a tax-inclusive price, it reverses the calculation and extracts the tax using rate divided by 100 plus rate. Pick the mode that matches how your invoice states the price, and consider a tax professional for significant filing decisions.

  • Enter the transaction amount in rupees.
  • Select the tax rate and choose exclusive or inclusive mode.
  • Read the tax amount, net value, and total from the results.
