How to work out 30% off $100

Turn the discount into a decimal: 30 ÷ 100 = 0.3.
Multiply by the price: 0.3 × $100 = $30 — that is the amount you save.
Subtract the saving from the price: $100 − $30 = $70.

Mental-math shortcut: Take 10% and multiply by three. (1% of $100 is $1, so 30% is $1 × 30 = $30.)

30% off $100 is a straight $30 discount for a $70 price — the tidiest example of this rate. Thirty per cent off is a common Black Friday and mid-season figure. Any percentage of 100 equals the number itself, so the discount is simply "30".

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.
