About Discount Calculator Online

This tool calculates the final price after a percentage discount and tells you how much you save. Enter the original price and the discount percent, and it instantly shows the discounted price and the savings amount.

Useful at the cash register when a sign says "30% off" but you want to confirm the actual amount, when comparing competing deals (40% off $100 vs 50% off $120 — same final price), or when planning markdowns for your own store.

The tool also supports stacked discounts — apply one discount on top of another to see the total reduction, which is not the same as adding the percentages together.

How to use this tool

How to compute the sale price after a percentage discount

  1. Enter the original price

    "Original price" is the listed price before the discount. Use the currency you'll be paying in — the tool returns numbers, not formatted prices.

  2. Enter the discount %

    "Discount %" is the percent off (e.g. 25 for a 25% sale). Values over 100 produce a negative "you pay" — a store-credit/cashback scenario the tool doesn't otherwise interpret.

  3. Press Run

    Result returns youPay (price − price × discount% ÷ 100) and savings (price × discount% ÷ 100), each rounded to 2 decimals.

  4. Stacking discounts isn't multiplicative here

    A 20% + 10% sequence is NOT 30% off; it's `price × 0.8 × 0.9 = 0.72` (28% off). Run the tool twice in sequence — feed the first youPay back as the second Original price.
