What does percent off mean?
A percent off tells you what share of the price comes off. At 25% off, a quarter of the price comes off and you pay the other 75%. The bigger the original price, the more dollars the same percent saves.
How to calculate percent off
Here it is with your numbers:
- Turn the discount into a decimal: 25 ÷ 100 = 0.25.
- Take it away from 1: 1 − 0.25 = 0.75, so you pay 75% of the price.
- Multiply the original price by it: $113.00 × 0.75 = $84.75.
It means you pay $84.75 and keep $28.25 of the $113.00.

Why 20% off plus an extra 10% isn't 30%
Stores often take "an extra 10% off" the sale price. The second discount comes off the already reduced price, so the two together are less than they add up to. A $100 item at 20% off is $80. An extra 10% off $80 is $8, so you pay $72: that's 28% off in total, not 30%.
Order doesn't matter: 10% then 20% gives the same $72. Open "Extra discount and sales tax" above to try it with your own prices.

How do you calculate percent off a price?
Multiply the price by 1 minus the discount as a decimal. $113 at 25% off is 113 × 0.75 = $84.75, a saving of $28.25.
How do you calculate 20 percent off?
Multiply the price by 0.8, because at 20% off you pay 80%. A $50 item at 20% off is 50 × 0.8 = $40, a saving of $10.
