What does this mean?
This calculator turns a percentage off into the actual price you pay and the money you save. It also handles a stacked “extra % off” coupon and optional sales tax, so the final number matches what you will really see at the register.
How it works
The first discount is applied to the original price. Any extra percent off is then applied to that reduced price (coupons stack multiplicatively, not by adding the percentages). Sales tax, if any, is added at the end. The effective discount shows your total saving as a single percentage.
A quick example
A $120 item at 25% off costs $90, saving you $30. Add a stacked 10% coupon and you pay $81 — an effective 32.5% off, not 35%, because the second discount applies to the already-reduced price.
Tip: two stacked discounts are always worth less than adding the percentages together. “25% then 10%” is 32.5% off, never 35%.
Frequently asked questions
How do I calculate a discounted price?+
Multiply the original price by (1 minus the discount as a decimal). For 25% off, multiply by 0.75. This calculator does it instantly and also shows the amount saved.
Do stacked coupons add up?+
No. A 25% discount followed by an extra 10% off is applied to the already-reduced price, giving 32.5% off in total — less than simply adding 25% and 10%.
Should I add tax before or after the discount?+
Discounts almost always apply to the pre-tax price, and tax is added to the discounted amount. This calculator follows that order when you enter a tax rate.
Can I use any currency?+
Yes. Pick your currency symbol and number format at the top and every amount updates to match.
