You're paying 75% of the original price

How to use it

  1. 1Enter the original price and choose your currency.
  2. 2Enter the discount percentage, and an extra discount too if it stacks with the first.
  3. 3Read the final price, total savings, effective discount rate, and the bar showing what share of the price remains.

Example

An $80 item with a 25% discount: the savings are $80 × 25% = $20, so the final price is $80 − $20 = $60. Stack an extra 10% off on top and the final price drops to $54 — a 32.5% effective discount, not the 35% you'd get by just adding the two percentages together.

How it works

The savings amount is the original price multiplied by the discount percentage: price × (discount ÷ 100). The final price is simply the original price minus that savings amount. If you add an extra discount, it's applied to the already-discounted price rather than the original — that's why stacked discounts multiply instead of adding, and the “effective discount” figure shows the true combined rate against your original price.
