Discount Calculator
Calculate sale price, discount amount, and final price after a percentage discount.
How this calculator works
How to use this calculator
Enter the original price and discount percentage. Optionally enter a tax rate to estimate the final price after tax.
Formula used
Discount Amount = Original Price × Discount %. Price After Discount = Original Price − Discount Amount. Final Price = Price After Discount × (1 + Tax Rate).
Example calculation
If the original price is $120 and the discount is 25%, the discount amount is $30 and the price before tax is $90.
What the result means
The final price shows what you pay after applying the discount and optional tax.
Frequently asked questions
Does tax apply before or after the discount?
This calculator applies tax after the discount.
Can I enter 0% tax?
Yes. Leave the tax field blank or enter 0.
Can discount be more than 100%?
The calculator accepts the value, but a discount above 100% creates a negative pre-tax price and usually does not represent a normal sale.
