How to Calculate Percentages

Calculating percentages is about figuring out proportions out of 100. In mathematical terms, a percentage is a number or ratio expressed as a fraction of 100. Below are some common formulas you might use:

  • To calculate a percentage of a whole number, divide the number you want to find a percentage for by the total number, then multiply by 100.
  • To increase or decrease a number by a percentage, convert the percentage to a decimal and multiply. Add this to the original number to increase, or subtract to decrease.
  • To find the percentage difference between two numbers, subtract the smaller number from the larger one, divide by the smaller number, then multiply by 100.

Examples of Percentage Calculations

Let's assume that you've scored 45 out of 50 in a test. To find out the percentage:

45 (your score) / 50 (total score) * 100 = 90%

This means you've scored 90% on your test.

If you want to increase a $20 amount by 15%, here's how you'd calculate:

20 (original amount) * 0.15 (15% converted to a decimal) = $3

So, you'd have $20 + $3 = $23 after a 15% increase.
