This discount calculator turns any advertised "percent off" into the real numbers that matter: how much you actually save and what you'll pay at the register. Enter an original price and a discount percentage to see the sale price instantly, or switch to reverse mode to work out the discount percentage from a price you were charged. It's built for shoppers comparing deals, resellers pricing markdowns, and anyone tired of doing sale-day math in their head.
A discount is simply a percentage taken off an original price. The tool multiplies the original price by the discount rate to find your savings, then subtracts that from the original to give the sale price. The formula is Savings = Original Price × (Discount % ÷ 100), and Sale Price = Original Price − Savings.
Reverse mode answers the opposite question. If you know the original and final prices, it finds the discount percentage using Discount % = (Original − Sale) ÷ Original × 100. That's handy for checking whether a "50% off" tag was applied correctly, or for figuring out the effective discount after a coupon stacks on a clearance price.
Multiply the original price by the discount rate expressed as a decimal (for example, 25% becomes 0.25) to get the amount you save. Subtract that saving from the original price to find the final sale price. This calculator does both steps automatically as you type.
Divide the amount you saved by the original price, then multiply by 100. If a $200 item cost you $150, you saved $50, and $50 ÷ $200 × 100 = 25% off. Use reverse mode to do this without any manual arithmetic.
Stacked discounts apply one after the other, not added together, so 20% then 10% is not 30% off. Take 20% off first, then 10% off the reduced price. On a $100 item that's $80, then $72, an effective discount of 28%.
No. This calculator shows the discounted price before tax, since tax rates vary by location. Add your local sales tax to the sale price to estimate the final checkout total, or use a dedicated sales tax calculator for the exact amount.
