Discount Calculator
Know exactly what you will pay at the till. Add an optional second discount to see why “50% off then 20% off” is not 70% off. The sale price, amount saved and effective percentage off all update instantly as you type.
Applied after the first discount
Plain English
How it works
- Multiply the price by the discount rate to get the saving.
- Subtract the saving from the original price.
- If a second offer applies, run it against the already-reduced price, not the original.

Answers
Frequently asked questions
How do I calculate a discount quickly in my head?
Take 10% by moving the decimal one place left, then scale. 30% of $80 is three lots of $8 = $24.
Do two discounts add together?
No, they multiply. 20% plus 20% is 36% off in total, not 40%.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount ÷ 100). $67.49 after 25% off was $89.99.
Is the discount applied before or after tax?
It varies by retailer and region. Use the tax calculator alongside this one to check both orders.
