🎯 Triple Discount Calculator
See what happens when three discounts are applied one after another, such as a sale price plus a coupon plus a loyalty discount.
Why stacked discounts don’t just add up
When a store applies several discounts to the same item, they are usually applied one after another to the already-reduced price, not added together. Three 10% discounts do not equal 30% off; each discount is smaller in dollar terms because it applies to a shrinking price.
The formula
Each discount multiplies the running price by (1 − Discount% ÷ 100), in sequence: Final Price = Price × (1 − d1) × (1 − d2) × (1 − d3). The calculator also shows the effective combined discount percentage compared to the original price.
Enter the original price and up to three discount percentages, in the order they would be applied, to see the true final price. This tool is for general shopping and budgeting use and does not include tax.
