I scored 43 out of 60 on a test. How do I enter this?

Enter Part = 43 and Whole = 60. The calculator returns approximately 71.67%.

Can the result exceed 100%?

Yes. If the part is larger than the whole (e.g. actual sales exceeded the target), the percentage will be above 100%.

What is the difference between this and percent change?

This calculator finds what fraction one number is of another as a percentage. Percent change measures how much a value grew or shrank relative to a starting point.

Formula

Percentage = (Part / Whole) x 100

How it works

Divide the part by the whole, then multiply by 100 to express the result as a percentage.

Worked example

30 is what percent of 200?

Divide: 30 / 200 = 0.15
Multiply by 100: 0.15 x 100 = 15%

Common mistakes to avoid

Dividing the whole by the part instead of the part by the whole, producing the inverse of the intended percentage.
Forgetting to multiply by 100, reporting the raw decimal ratio (e.g. 0.75) instead of 75%.
Confusing this with the percent-of-number tool; this finds the rate, the other applies it.
