What is 50% off $100?

How it's calculated

1. Find the discount: 50% of $100 = $100 × 0.5 = $50.00
2. Subtract it from the price: $100 − $50.00 = $50.00

Shortcut: with 50% off you pay 50% of the price, so multiply $100 × 0.5 = $50.00 in one step.

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