Discount Calculator

About the Discount Calculator

Whether you're shopping a sale, negotiating a business deal, or applying a coupon code, knowing exactly how much you save at any discount percentage is instantly useful. Our discount calculator works in three ways: find the sale price from a percentage off, find what percentage discount was applied, and find the original price when you know the sale price and discount rate.

How It Works

Sale Price = Original Price × (1 − Discount%/100). Discount Amount = Original Price − Sale Price. Discount Percentage = (Discount Amount ÷ Original Price) × 100. Original Price = Sale Price ÷ (1 − Discount%/100). For a $150 item at 30% off: Sale Price = $150 × 0.70 = $105. Savings = $45.

Tips & Best Practices

• ✓Stack discounts carefully: 20% off + an additional 10% off = 28% off total, not 30%.
• ✓Black Friday/Cyber Monday discounts average 20–30% — pre-pandemic levels have largely returned.
• ✓Cashback credit cards effectively add 1–5% discount on top of any sale price.
• ✓Price comparison across retailers often beats any single store's discount.
• ✓Bulk discounts: understand your true unit price across different package sizes.
