Frequently Asked Questions
How do I calculate a discount percentage from the original and sale price?▾
Enter the original price and sale price into the calculator. The discount percentage is calculated as (original price minus sale price) divided by original price, times 100. This tool does the math instantly.
How do stacked discounts work?▾
Stacked discounts are applied sequentially, not added together. For example, 20% off then 10% off a $100 item gives $72, not $70. The second discount applies to the already-reduced price.
Can I add sales tax to the discounted price?▾
Yes. Enter your local sales tax rate and the calculator adds tax to the final discounted price, showing you the true out-of-pocket cost.
What is the difference between a percentage discount and a dollar discount?▾
A percentage discount reduces the price by a proportion (e.g., 20% off), while a dollar discount reduces it by a fixed amount (e.g., $10 off). This calculator supports both types.
