How to Calculate a Discount
Final price = original price − (original price × discount %).
A quick mental-math mistake is treating "25% discount" as if it means you pay 25% of the price. It's the opposite — a 25% discount means you pay the remaining 75%, so multiplying the price by 0.75 gets you straight to the final price in one step.
Worked example
An $80 item at 25% off.
Discount: 80 × 0.25 = $20
Final price: 80 − 20 = $60
A second example: a $120 jacket at 15% off.
Discount: 120 × 0.15 = $18
Final price: 120 − 18 = $102

Frequently Asked Questions
How do you calculate a discount?
Multiply the original price by the discount percentage (as a decimal) to get the discount amount, then subtract that from the original price to get the final price.
How do you find the original price from a sale price?
Divide the sale price by (1 − discount percentage as a decimal). For example, a $60 price after a 25% discount means the original was 60 ÷ 0.75 = $80.
Does discount stacking add percentages together?
No. Two stacked discounts of 20% and 10% don't equal 30% off — each discount applies to the already-reduced price, so the combined effect is smaller than the sum.
Can you show discount stacking with real numbers?
Take a $100 item with 20% off, then an additional 10% off. The first discount brings it to $80 (100 − 20). The second discount is 10% of $80, which is $8, bringing the final price to $72. The combined discount is 28% off the original $100, not the 30% you'd get by just adding the two percentages.
