Why use Discount Calculator?

This calculator finds the final sale price after applying one or two percentage discounts. When a second, stacked discount is entered, it is applied to the already-discounted price — matching how most stores apply an extra coupon on top of a sale price — so the combined savings are shown accurately rather than simply adding the two percentages together.

Frequently asked questions

How are stacked discounts calculated?

The second discount is applied to the already-discounted price, not the original price — the same way most retailers apply a coupon on top of a sale price.

Why is the total percent off less than adding the two discounts together?

Because the second discount applies to a smaller, already-reduced price, the combined effective discount is slightly less than simply adding the two percentages.

Can I use this for tax-inclusive prices?

Yes — enter whatever price you want the discount applied to.
