FAQ

Each discount applies to the price after the previous one, so 20% then 10% is not 30% — it is an effective 28%.

Switch to the original price mode and enter the discounted price with the percentage that was taken off.

After, which matches how most retailers calculate the total.

The saving is divided by the original price and multiplied by 100.

Results are shown to two decimal places, so a shop's own rounding may differ by a cent.

About this tool: Discount Calculator

Know the real price after every discount

The Discount Calculator computes the final price after any discount — single percentage, fixed amount, or stacked promotions like “20% off, then an extra 10%”. Enter the original price and the discount terms; get the exact amount you will pay and exactly how much you save.

Retail maths is designed to be confusing: percentages off percentages, “buy two get one free”, plus-tax-versus-with-tax. Stacked discounts rarely add up the way shoppers guess — 20% then 10% is 28% off, not 30% — and the tool shows the true arithmetic so you can compare offers fairly.

Calculations run locally and instantly. Use it at sales, when comparing coupon codes, when budgeting bulk purchases, or when setting your own promotional prices as a seller — the same math that protects a buyer guides a fair discount.
