What Percentage is a Specific Number

Determine what percentage a specific number represents out of a total.

Example: 80 is 80% of 100

LEARN HOW TO USE THE CALCULATOR

Formula for "What Percentage is a Specific Number":

(Part / Whole) * 100%

For example, if you want to find out what percentage 80 is of 100, you would divide 80 by 100, then multiply the result by 100 to convert it to a percentage. So (80 / 100) * 100% = 80%

Translate a Percentage to a Value

Translate a percentage into a specific value within a whole.

Example: 20% of 100 is 20

LEARN HOW TO USE THE CALCULATOR

Formula for "Translate a Percentage to a Value":

(Percentage / 100) * Whole

For example, if you want to find out what 20% of 100 is, you would divide 20 by 100, then multiply the result by 100. So (20 / 100) * 100 = 20

Determine Percentage Change Between Two Numbers

Calculate the percentage change between two numbers.

Example: The percentage change from 10 to 20 is 100%

LEARN HOW TO USE THE CALCULATOR

The formula for "Determine Percentage Change Between Two Numbers":

((New Value - Old Value) / Old Value) * 100%

For example, if you want to calculate the percentage change from 10 to 20, you would subtract 10 from 20, divide the result by 10, then multiply by 100 to convert it to a percentage. So ((20 - 10) / 10) * 100% = 100%

Calculate Value Increase or Decrease Based on Percentage

Find out how much a value increases or decreases when a specific percentage is applied.

Example: 10% increase on 100 is 10

LEARN HOW TO USE THE CALCULATOR

The formula for "Calculate Value Increase or Decrease Based on Percentage":

(Percentage / 100) * Old Value

For example, if you want to find out how much a value increases by 10% from 100, you would divide 10 by 100, then multiply the result by 100. So (10 / 100) * 100 = 10
