How to calculate a discount
Enter the original price and the discount percentage. The final price is the original price minus the discount amount. For example, 25% off $80 saves $20, so you pay $60.
Tip: a “20% off” deal means you pay 80% of the price. Multiply the price by 0.8 to get the final price directly.
Frequently asked questions
How do I calculate the price after a discount?
Subtract the discount from the original price: final = original × (1 − discount ÷ 100). For 30% off $50, you pay 50 × 0.7 = $35.
What does “20% off” mean?
It means the price is reduced by 20%, so you pay 80% of the original. A $100 item becomes $80.
How much do I save?
Savings = original price × discount ÷ 100. The calculator shows this automatically.
Can I stack two discounts?
For two successive discounts, apply them one after another — e.g. 20% then 10% is not 30%, but 1 − (0.8 × 0.9) = 28%.
