Sale price from a percent off

Retail math is usually the same: original × (1 − discount%). This page opens in Discount mode so you see both the final price and the dollar amount saved, without switching modes first.

Adding sales tax after a discount? Use the Sales Tax Calculator. For percent change and “what is P% of N,” open the Percentage Calculator.

FAQ

How do I calculate a percent-off price?

Enter the original price and the discount percent. You get the sale price and how much you save.

Does this handle stacked coupons?

No. Apply one percent at a time, or use the Percentage Calculator’s other modes if you need different math.

Can I use this for tips or tax?

For adding a percent onto a bill, use the Sales Tax Calculator (Add tax). This page is for markdowns — price after a percent off.

Are my numbers uploaded?

No. All math runs in your browser. Nothing is sent to a server.

What if the discount is a fixed dollar amount?

This page is percent-off only. Subtract a fixed amount yourself, or use the Percentage Calculator when you need other percent modes.
