# Discount Calculator — Percent Off & Final Price

Work out the sale price and how much you save from a price and a discount percentage. 100% in your browser — free, no sign-up.

## 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.

## How to

1. Enter the original price.
2. Enter the discount percentage.
3. Read the amount saved and the final price instantly.

## FAQ

**How do I calculate a percentage discount?**

Multiply the price by the percent ÷ 100 to get the amount off, then subtract it. E.g. 25% off 80 = 20 off, final 60.

**How do two discounts stack?**

They apply one after another, not added: an extra 10% off a 20%-off price is 0.9 × 0.8 = 72% of original (28% off), not 30% off.

**How do I find the percent off from two prices?**

Percent off = (original − sale) ÷ original × 100. E.g. from 80 to 60 is (20 ÷ 80) × 100 = 25% off.
