Discount Calculator

What Does This Calculator Do?

The discount calculator applies a percentage discount to an original price and shows both the final price you'll pay and the exact amount saved — useful for comparing sale prices or verifying a discount at checkout.

Worked examples

An original price of 2,000 with 25% off saves 500, leaving a final price of 1,500.

For successive discounts of 20% and 10% on 100, calculate 20% off first to get 80, then enter 80 with 10% off to get 72. The combined saving is 28%, not 30%.

A 100% discount on 45 gives a final price of 0 and a saving of 45.

Formula / Calculation Method

Savings = Original Price × (Discount % ÷ 100); Final Price = Original Price − Savings.

Common Use Cases

Check a sale price before checkout

Apply successive percentage coupons in the stated order

Compare final prices from shops with different original prices

Compare the amount you actually pay

Enter the price before the discount and a percentage from 0 to 100. A coupon worth 20 currency units is different from a 20% coupon. For a fixed-amount coupon, subtract that amount separately and check the retailer’s order of operations.

Tax, shipping, and stacked offers

The result covers one item and one percentage reduction. It does not add shipping, tax, minimum-spend rules, caps, or membership charges. Sequential discounts multiply the remaining price, so adding the percentages gives the wrong saving. Reuse the final price as the input for the next discount.

The final price is rounded to two decimal places. The currency selector only changes the symbol. A lower percentage discount can still be the better deal if its starting price is lower.

Frequently Asked Questions

Can I calculate stacked discounts?

Yes, one at a time. Use the first final price as the original price for the next percentage. Check whether the retailer permits combining those offers.

Why is a 20% increase not undone by a 20% discount?

The percentages use different starting amounts. Increasing 100 by 20% gives 120; taking 20% off 120 leaves 96.
