Storewide discount or initial markdown percentage
Stacked promo code or loyalty discount applied after primary markdown
Total amount due at checkout before sales tax
How to Use This Calculator
- Enter the original sticker price of the product.

- If you have an extra promo code or VIP coupon, enter it in Additional Discount.
- Review the final checkout price and your exact total dollar savings.
Formula & Calculation Methodology
Consecutive or stacked discounts compound multiplicatively rather than additively (a 30% discount followed by a 10% coupon equals 37% total off, not 40%).
Worked Example
$120.00 jacket with 30% store discount plus an extra 10% coupon code
Frequently Asked Questions
Why do stacked discounts not add together directly?↓
When an extra 10% discount is applied, retailers take 10% off the already discounted sale price, not off the full original retail price. Therefore, 30% off + 10% off yields a 37% net discount rather than 40%.
Does this calculator include retail sales tax?↓
This calculation reflects pre-tax checkout prices. In most jurisdictions, sales tax is assessed on the final discounted price rather than the original sticker price.
How does cashback compare to an instant percentage discount?↓
An instant discount reduces cash leaving your wallet immediately at the register, whereas cashback requires waiting for monthly statement credits or third-party rebate payouts.
What is the fastest way to calculate a 20% discount in your head?↓
Move the decimal point one place to the left to find 10%, then double that number. For example, 10% of $60 is $6, so 20% is $12, making the sale price $48.
