Discount Calculator

To calculate a discount, multiply the original price by the discount percentage, then subtract that amount from the original price.

Example:
If an item costs $100 and the discount is 20%, the discount amount is $20, so the final price is $80.

If you know the final price and the discount percentage, you can work backwards.

Example:
If the final price is $80 after a 20% discount, the original price was $100.

When multiple discounts are applied (for example, 20% off and then an additional 10% off), they are calculated sequentially - not added together.

Example:
First discount: 20% off $100 → $80
Second discount: 10% off $80 → $72
Final price: $72 (not 30% off)

The discount amount is the original price multiplied by the discount percentage, divided by 100.

Formula:
Discount amount = original price × discount percentage / 100

Subtract the discount amount from the original price. You can also multiply the original price by the percentage you still pay.

Example:
For 25% off $80, you pay 75% of $80, which is $60.

Subtract the final price from the original price, divide by the original price, then multiply by 100.

Example:
If $50 becomes $40, the discount is $10. $10 divided by $50 is 0.2, so the discount is 20%.

Yes. A 50% discount means you subtract half of the original price, so the final price is half of the original price.

In most checkout situations, tax is calculated after the discount is applied. Rules can vary by location and product type, so check the receipt or local tax rules when exact tax handling matters.
