Discount Calculator

A discount calculator works out what you'll actually pay when an item is on sale, and how much you save. It's handy in shops and online sales, where offers are often stacked: a sale price, then a coupon, then a bank or card discount, sometimes with tax added at the end.

Enter the original price, the main discount, an optional extra discount and an optional tax rate. The calculator shows the final price, the money saved, the true combined discount percentage and the price after the first discount alone. It works in rupees or any currency.

A second discount applies to the already-reduced price, not the original. 30% off and then 10% off leaves 0.70 × 0.90 = 0.63 of the price, a total discount of 37%, not 40%.

Where tax is charged after the discount, as with GST on a discounted invoice, the tax is worked out on the reduced amount. Prices in Indian shops are usually shown including GST, in which case leave tax at zero.
