How it works
- Savings = price × discount % ÷ 100.
- Sale price = price − savings.
- Final price = sale price + (sale price × tax % ÷ 100).
Frequently asked questions
Is tax applied before or after the discount?
In most places sales tax is charged on the discounted price, which is how this calculator works.
How do I combine two discounts?
Apply them one after another: run the first discount, then use the sale price as the new original price for the second. 20% + 10% off is 28% off, not 30%.
