Percent Off Calculator
See the final price after 15%, 30%, or 70% off — plus the amount you save. Stack multiple discounts and compare deals in seconds, right in your browser.
"30% off" sounds great until you are standing in the aisle doing mental math on a $79.99 jacket. A percent-off calculation multiplies the original price by (1 − discount), and the savings are simply the difference — but stacked discounts are where shoppers lose money: 20% off, then an extra 25% off, is not 45% off.
Enter the original price and the discount to get the sale price and savings instantly. Stack a second discount to see the true combined rate, and compare two competing offers side by side before you checkout.

Frequently asked questions
How do I calculate 20% off a price?
Multiply the price by 0.80 (that is 100% minus the 20% discount). A $45 item at 20% off costs $45 × 0.80 = $36, saving $9. The calculator shows both the final price and the exact amount saved.
Is 20% off plus 25% off the same as 45% off?
No. The second discount applies to the already-reduced price: $100 → 20% off → $80 → 25% off → $60. That is a combined 40% discount, not 45%. Stacking the two in this calculator reveals the true effective rate so you can compare offers honestly.
