What is 21% off $100?
How is 21% off $100 determined?
The long formula for determining percentage off is (100 - percent) / 100 * amount. In this case, it would be (100 - 21) / 100 * 100, for an answer of $79.00.
However, if you can do some quick math in your head, you can also subtract the percentage from 100, add a decimal point before that number, and multiply that number by the amount. So, using the same example, you would multiply 0.79 (100 - 21 with the decimal added before the 79) by 100 for the same answer of $79.00. Unless you're really good, you'll probably need a calculator for anything other than very common percentages and amounts.
