Discount Calculator

When retailers offer multiple discounts, they're typically applied sequentially, not added together.

For example, 20% off + 10% off doesn't equal 30% off.

The second discount applies to the already-reduced price.

Our calculator shows you the true final price when stacking discounts.

In most cases, sales tax is calculated on the price AFTER discounts are applied.

However, some jurisdictions calculate tax on the original price.

Use the toggle to see both scenarios and understand your actual final cost.

If you know the final sale price and want to find the original price, divide the sale price by (1 - discount%).

For example, if something costs $80 after a 20% discount: $80 ÷ 0.8 = $100 original price.
