Discount Calculator
Calculate sale savings and final price after a percentage discount.
Quick answer
How do you calculate a discount?
Multiply the price by the discount percent, then subtract it. For 25% off $80: 80 × 0.25 = $20 off, so the sale price is $60. Or multiply by (1 − discount): 80 × 0.75 = $60.
Final price = original × (1 − discount%/100) • Savings = original × discount%/100
