Discount Calculator
Find the markdown amount, sale price, final total after tax, and your total savings. You can also compare stacked discounts to a single larger discount.
Double discount mode
Apply a second markdown after the first one, like 20% off plus an extra 10% off.
How to Use
- Enter the original price of the item before any sale or coupon is applied.
- Choose a discount percentage with the quick buttons or type your own custom markdown.
- Add an optional sales tax rate to see your estimated final checkout total.
- Turn on double discount mode if the deal includes a second markdown, then compare it to a single combined discount.
Frequently Asked Questions
How do I calculate a discount amount?
Multiply the original price by the discount percentage. For example, a 20% discount on a $50 item saves you $10, so the sale price becomes $40.
How do I find the sale price after a discount?
Subtract the discount amount from the original price. If an item costs $80 and the discount is 25%, the discount amount is $20 and the sale price is $60.
Is sales tax calculated before or after the discount?
In most places, sales tax is applied to the discounted selling price, not the original list price. That means the lower sale price usually reduces the tax you pay too.
Why is 20% off plus 10% off not the same as 30% off?
The second discount applies to the already discounted price, not the original price. A 20% discount followed by 10% off is effectively a 28% discount overall, not 30%.
What does total savings include?
Total savings shows how much lower the discounted price is than the original price. It measures the markdown savings before any sales tax is added back in.
