Formula
Divide the percent off by 100 to convert it to a decimal, subtract from 1, then multiply by the original price. For 25% off $80: 1 − 0.25 = 0.75, then $80 × 0.75 = $60.

How do I calculate percent off in my head?
For 10% off, move the decimal one place left (10% of $80 = $8). For 20% off, double that ($16). For 25% off, divide the price by 4. For 15% off, find 10% then add half of that. These shortcuts work for any round number.
Does the percent off apply before or after tax?
Discounts are applied to the pre-tax price in most countries. Tax is then calculated on the reduced price. So 20% off a $100 item gives you $80, and tax is charged on $80 — not on the original $100. Use the sales tax calculator to find the final total after tax.
