What is 70% off $20?

How it's calculated

1. Find the discount: 70% of $20 = $20 × 0.7 = $14.00
2. Subtract it from the price: $20 − $14.00 = $6.00

Shortcut: with 70% off you pay 30% of the price, so multiply $20 × 0.3 = $6.00 in one step.

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