How to work out 20% off $40
- Turn the discount into a decimal: 20 ÷ 100 = 0.2.
- Multiply by the price: 0.2 × $40 = $8 — that is the amount you save.
- Subtract the saving from the price: $40 − $8 = $32.
Mental-math shortcut: Divide the price by five, or pay 80% of it (price × 0.8). (1% of $40 is $0.40, so 20% is $0.40 × 20 = $8.)

Method & sources
Saving = price × discount ÷ 100, and sale price = price − saving. Amounts are rounded to the cent only for display. Stacked discounts multiply rather than add — 20% off and then another 20% off is 36% off in total, not 40% — and sales tax, where it applies, is charged on the discounted price.
