Discount Calculator formula

Original price → first discount → additional discount → tax. Two discounts are sequential, not added together.

Worked example

A $100 item with 20% then 10% off costs $72 before tax, not $70.

How to use this calculator

  1. Enter the original price and first discount.
  2. Optionally add a second discount and tax.
  3. Review savings and final price.

Important assumptions and limitations

Tax is applied after both discounts. Enter the rate that applies to your purchase.
