Frequently asked questions

How do I find a percentage of a number?
Convert the percentage to a decimal by dividing by 100, then multiply that decimal by your number. For example, 15% of 240 is 0.15 × 240 = 36.
What is the difference between a percentage and a percentage point?
A percentage expresses a share of a total, while a percentage point is an absolute difference between two percentages. If a rate rises from 4% to 6%, that is a 2 percentage-point increase but a 50% relative increase in the rate itself.
Can I enter a percentage greater than 100?
Yes. Values above 100 are valid — for example, 150% of 80 is 120, which is 1.5 times the original number.
How is rounding handled?
The result is rounded to two decimal places. For most everyday calculations this is sufficient, but if you need more decimal places for a scientific or financial calculation, use the full precision from your own multiplication before rounding.

Walkthrough

Visual walkthrough

See how the percent becomes a multiplier and then scales the base value.

  1. 01

    Translate the percent

    15% ÷ 100 = 0.15

    A percentage is easier to use in multiplication once it is written as a decimal multiplier.

    Decimal multiplier 0.15

  2. 02

    Scale the base value

    240 × 0.15 = 36

    Multiply the base value by the decimal multiplier to isolate the requested share.

    Portion found 36

  3. 03

    Read the result
