How it works
Subtract the discount from the original price, then apply the optional tax to the discounted subtotal. The savings figure compares prices before tax. Local checkout rules can differ, so confirm how a retailer applies tax and coupons.
Standard formula
price × (1 − discount / 100) × (1 + tax / 100)Worked example
A 200 item with a 15% discount costs 170 before tax and saves 30. Adding 10% tax gives a final price of 187.
Frequently Asked Questions
Is tax applied before or after the discount?
This tool applies tax after discount. Set tax to zero for a price without tax.
Can I combine two discounts?
Apply them sequentially. A 20% discount followed by 10% equals a 28% total discount, not 30%.
What does savings mean?
It is the original price minus the discounted subtotal, excluding tax.
Can the discount be 100%?
Yes. The discounted subtotal and tax are both zero in this model.
