Overview of the Discount Calculator

The Discount Calculator handles both percentage and fixed-amount discounts and lets you add tax on the discounted price. It shows the discount in rupees, the price after discount, the tax and the final amount you pay.

Tax is normally charged on the discounted price, so a bigger discount also reduces the tax. To stack two percentage discounts use the Percent Off Calculator; to add or remove GST on any price use the Sales Tax Calculator.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Work out the discount: price × percent ÷ 100, or the fixed amount.
  2. Subtract it from the price to get the discounted price.
  3. Tax = discounted price × tax rate ÷ 100.
  4. Final price = discounted price + tax.
discount = price × % ÷ 100   net = price − discount
final = net × (1 + tax ÷ 100)
