What the discount calculator does

Enter an original price and a discount percentage and it shows two things instantly: how much you save, and the final price after the discount. Useful for sales, coupons, and checking a deal before you buy.

How it works

Both numbers update as you type, computed entirely in your browser — nothing is uploaded. It handles any price and any percentage, so it works for a small coupon or a big clearance discount alike.

The formula

Discount amount = price × (percent ÷ 100). Final price = price − discount amount. Example: 25% off a 80.00 item = 20.00 saved, final price 60.00. To go the other way (percent off from two prices): percent = (price − sale) ÷ price × 100.

Stacked and extra discounts

Discounts usually apply one after another, not added together: an extra 10% off an already 20%-off price is 0.9 × 0.8 = 72% of the original (28% off), not 30% off. Apply each discount to the running price rather than summing the percentages.
