What is 75% off $20?

How it's calculated

1. Find the discount: 75% of $20 = $20 × 0.75 = $15.00
2. Subtract it from the price: $20 − $15.00 = $5.00

Shortcut: with 75% off you pay 25% of the price, so multiply $20 × 0.25 = $5.00 in one step.

Sales tax, if any, is usually added after the discount and isn't included here.
