Discount Calculator
Calculate the final price and total savings after one discount, or stack two discounts to see the real final price.
Optional, applied after the first
Final price
$68.00
What Your Result Means
The final price is what you'll actually pay after the discount (or discounts) are applied. The effective discount percentage shows your true total savings, which is especially useful when stacking two discounts, since they don't simply add together.
How It Is Calculated
Final Price = Original Price × (1 - Discount% / 100), applied once per discount
Worked Example
What is 20% off $85? $85 × (1 - 0.20) = $68.00, so you save $17.00. Stack a second 10% discount and the final price becomes $61.20 - an effective discount of about 28%, not 30%, because the second discount applies to the already-reduced price.
Important Assumptions
- The second discount is applied to the price after the first discount, not the original price.
- Does not include sales tax.
Frequently Asked Questions
- Why don't two discounts just add together?
- Because the second discount is calculated on the already-reduced price, not the original price - so two 10% discounts stacked together save less than a flat 20% discount.
