A discount calculator works out the final price of a discounted item. Enter the original price and the discount percentage, and it returns your sale price, the amount you save, and the final price including sales tax — so you know exactly what you’ll pay at the register.
It’s perfect for sales, clearance racks, coupons and Black Friday deals, where stacking percentages and tax can make the real price hard to work out in your head.
To calculate a discount, multiply the price by the discount percentage, then subtract it from the original price:
Savings = Price × (Discount % ÷ 100) · Sale price = Price − Savings
For example, a $80 item at 25% off: $80 × 0.25 = $20 saved, leaving a $60 sale price. Add 7% sales tax and the final price is $64.20.
Final sale price for common discounts (before tax):
| Original | 10% off | 25% off | 50% off |
|---|---|---|---|
| $20 | $18.00 | $15.00 | $10.00 |
| $50 | $45.00 | $37.50 | $25.00 |
| $100 | $90.00 | $75.00 | $50.00 |
| $200 | $180.00 | $150.00 | $100.00 |
Two discounts don’t simply add up. An extra 20% off an item already 50% off is not 70% off — it’s 20% off the already-reduced price. A $100 item at 50% off becomes $50, and 20% off that is $40, an effective discount of 60%, not 70%.
| Term | What it means |
|---|---|
| Original price | The full price before any discount. |
| Sale price | The price after the discount is applied. |
| Savings | The dollar amount the discount removes from the price. |
| Stacked discount | A second discount applied to an already-reduced price. |
Multiply the original price by the discount percentage as a decimal to find your savings, then subtract that from the price. A $80 item at 25% off saves $20, for a $60 sale price.
Divide the amount you save by the original price, then multiply by 100. If a $50 item is on sale for $35, you save $15, which is $15 ÷ $50 × 100 = 30% off.
No. A second discount applies to the already-reduced price. An extra 20% off an item that's 50% off gives a 60% effective discount, not 70%, because the 20% comes off the lower price.
Sales tax is calculated on the discounted sale price, not the original price. This calculator applies your tax rate after the discount to show the true final price.
They mean essentially the same thing to a shopper — a reduction from the original price. "Markdown" is the retail term for permanently lowering a price, while "discount" often refers to a temporary sale or coupon.
