100 with 20% off = 80
250 with 15% off = 212.5
80 with 50% off = 40
FAQ
What is a discount percentage?
A discount percentage is the portion of the original price that is taken off. For example, a 20% discount on $100 means $20 is deducted.
How do you calculate the final price after discount?
Multiply the original price by (1 minus the discount percentage divided by 100). For example: 100 × (1 − 20/100) = 80.
What is the formula for calculating a discount?
Final Price = Original Price × (1 − Discount% ÷ 100). Amount Saved = Original Price × (Discount% ÷ 100).
How do I calculate 20% off a price?
Multiply the price by 0.80 (which is 1 − 0.20). For example, 20% off $150 = $150 × 0.80 = $120.
How do I find the original price before a discount?
Divide the sale price by (1 − Discount% ÷ 100). For example, if $80 is after a 20% discount: $80 ÷ 0.80 = $100.
