Triple Discount Calculator

Sale price, coupon, and loyalty discount all at once? Enter the original price and all three percentages — the calculator compounds them step by step.

Final price after 3 stacked discounts

$115.20

You save $84.80 — that's 42.4% off in a single discount.

How it compounds:

  1. After 20% off: $160.00
  2. After 20% off: $128.00
  3. After 10% off: $115.20

Stacked discounts multiply — each percentage applies to the already-reduced price, so a 20% + 20% stack is 36% off, not 40%.

Triple stacking example

Take a $200 jacket at 30% off, with a 15% coupon on top and a 10% member discount:

  1. 30% off $200 → $140
  2. 15% off $140 → $119
  3. 10% off $119 → $107.10

The listed numbers add up to 55%, but the real discount is 1 − (0.7 × 0.85 × 0.9) = 46.45%. Each percentage shrinks because it acts on an already-discounted price.

Only stacking two? Use the double discount calculator, or check single-discount price tables.
