Discount Calculator
Enter the original price and the discount percentage to see how much you save and what you'll pay. Useful at checkout, when comparing promotions, or when negotiating trade discounts. A discount and a percentage decrease are mathematically the same thing — the difference is context: a discount is applied to a price, while a percentage decrease describes any falling value. If you're a seller setting prices, the markup calculator shows the opposite direction — from cost to selling price.
When to use this calculator
Use this at the point of purchase to verify savings, when comparing two promotions (e.g. 20% off vs $30 off), or when calculating a trade or bulk discount before placing an order.

Compare Two Deals — Which Discount Is Actually Better?
A single discount is easy. Real shopping decisions rarely are: one store offers 25% off, another offers $20 off plus a members-only extra 10%, and the "bigger" number doesn't always win. Enter both offers below — including stacked discounts and dollar coupons — and see the true out-the-door price of each. Use the copy-link button to send the comparison to whoever you're deciding with.
Stacked discounts apply one after the other (30% + an extra 10% = 37% off total, not 40%). A dollar coupon comes off last, after all percentage discounts.
Deal A — You Pay

FAQ
What is 20% off $80?
20% off $80 saves you $16 — the final price is $64. Calculation: $80 × 0.20 = $16 saved.
What is 30% off $150?
30% off $150 saves you $45 — the final price is $105.
How do you calculate a discount?
Multiply the original price by the discount percentage divided by 100. For example, 25% off $200: $200 × 0.25 = $50 off, final price = $150.
What is the difference between discount and sale price?
The discount is the amount you save — the reduction from the original price. The sale price is what you actually pay. Final price = original − discount.
What is 50% off $120?
50% off $120 is $60 off — the final price is $60. A 50% discount always halves the price.
Is 30% off plus an extra 10% off the same as 40% off?
No. Stacked discounts apply one after the other, each on the already-reduced price. 30% off $100 leaves $70, then 10% off $70 leaves $63 — a 37% total discount, not 40%. Stores advertise "extra" discounts precisely because they sound bigger than they are.
Which is better: $15 off or 20% off?
It depends on the price. 20% off beats a $15 coupon whenever the price is above $75, because 20% of $75 is exactly $15. Below $75, take the flat $15. The deal comparison tool on this page works this out for any pair of offers.
How do I find the original price from a discounted price?
Use the reverse percentage calculator. Enter the remaining percentage (100 minus the discount) and the sale price to get the original. For example, $80 after 20% off means 80% remains — enter 80% and $80 to get $100.
