Percent Off (Discount) Calculator

The everyday “sale price” question — given a listed price and a discount percentage, what do you actually pay?

How it works

Multiplying the original price by the discount percentage gives the amount saved; subtracting that from the original price gives the final price.

What this does not include

This does not include stacked discounts (like “25% off, then an additional 10% off”) — applying discounts sequentially rather than adding the percentages together produces a different, smaller total discount than combining them would suggest.

How to use this calculator

  1. Enter the original price and the discount percentage.

A worked example

An $80 item with a 25% discount: amount saved = 80 × 0.25 = $20, final price = $60.

What the variables mean

Variable Meaning
Price Original price before discount
Discount percent Percentage being taken off

Edge cases worth knowing

A discount over 100% has no valid meaning — the item can’t cost less than nothing, so the calculator declines to show a result for a discount percentage that high.

Stacked discounts don’t simply add together — applying a 25% discount and then another 25% off the reduced price saves less than a flat 50%, since the second discount applies to a smaller starting amount.

Frequently asked questions

Why don’t stacked discounts just add together?

Each discount applies to the price *after* the previous discount, not the original price — “25% off, then 10% off” saves less than a flat 35% off would.

Does this include sales tax?

No — this calculates the discounted price before any tax; sales tax is typically applied to the discounted price, not the original.

What if the discount is a dollar amount instead of a percentage?

This calculator specifically handles percentage discounts — a flat dollar-amount discount is a simpler direct subtraction that doesn’t need a calculator.

The focus is on showing exactly which number goes into a formula and which assumptions a result depends on, so readers can tell when a figure applies to their situation and when it does not. Every finance page states what it does not account for as plainly as what it does.

Financial results are easy to state with false precision, so review focuses on whether the page makes its assumptions visible to a reader who is not looking for them.
