Discount Calculator
Sale price and how much you save
Spot the real deal. Enter the original price and the percent off to see the sale price and how much you save.
Working out a sale price
Multiply the price by the discount percent to get your savings, then subtract. A 30% discount on $80 saves $24, for a $56 sale price. Stacking coupons? Apply them one at a time.
Stacked and "extra % off" deals
Discounts don't simply add up. "30% off, then an extra 20% off" isn't 50% off — the second cut applies to the already-reduced price, so $100 → $70 → $56, a 44% total saving. Always apply percentages one after another, never by summing them.
Spotting a real bargain
A bigger percentage off a higher "original" price isn't always the better deal — compare the actual final prices. And remember sales tax applies to the discounted price, so the amount at the register is the sale price plus your local tax (use the sales tax calculator to add it).
Discount Calculator: frequently asked questions
How do I calculate a discount?
Multiply the original price by the discount percentage, then subtract that from the price to get the sale price.
What does 30% off mean?
You pay 70% of the original price — so $100 becomes $70.
How do I calculate two discounts stacked together?
Apply them in sequence, not by adding. For 25% off plus an extra 10%, take 25% off first ($100 → $75), then 10% off that ($75 → $67.50) — a 32.5% total discount, not 35%.
