About the Percent Off Calculator

Enter the original price and the discount to get the sale price and the amount saved. The calculator also works backwards, deriving the discount percentage from an original and a sale price, which is how you check whether an advertised claim is accurate.

Stacked discounts are where the arithmetic surprises people. Thirty percent off followed by a further twenty percent is not fifty percent off: the second discount applies to the already reduced price, so the combined effect is forty-four percent. The calculator applies successive discounts in order and reports the true combined percentage, along with the final price after tax if you add a rate, which is what you will actually pay at the register.

Key features of the Percent Off Calculator

Stacked discounts done properly

Each discount applies to the already-reduced price, so successive offers never simply add together.

Reverse mode

Enter two prices to get the actual discount percentage, which is how you check an advertised claim.

Percentage or fixed amount

Handles both ways a discount is advertised, including combinations of the two.

Tax added after

Optionally add a sales tax rate for the price you actually pay at the register.

Amount saved shown

The cash saving as well as the percentage, since one of those is easier to judge than the other.

    Read the final price

    The sale price and the amount saved, plus the total after tax if you add a rate.

Frequently asked questions

Multiply the price by the discount as a decimal to get the saving, then subtract it. Thirty percent off eighty is eighty times 0.3, which is twenty-four, leaving fifty-six.
