## How to Find Percent Increase

Percent increase is the growth in a value expressed as a percentage. It is the percent of change from the initial value to the final value.

To calculate the percentage increase of a value, use the following formula.

### Percent Increase Formula

The percentage of increase is defined as the difference between the initial value and final value divided by the initial value. The percent increase formula is:

p = final – initial / |initial| × 100

Thus, the increase in value expressed as a percentage is equal to the final value minus the initial value, divided by the absolute value of the initial, times 100.

**For example,** let’s calculate the percentage increase from 50 to 80.

p = 80 – 50 / |50| × 100

p = 30 / 50 × 100

p = 0.6 × 100

p = 60% increase

## How to Calculate the Growth by a Percentage

If the percent increase is known, you can calculate the growth of a value to the final value by multiplying the initial value by the percentage and adding that to the initial value.

final = (initial × p / 100) + initial

Thus, the final value is equal to the initial value times the percentage divided by 100, plus the initial value.

**For example,** let’s calculate the growth of the initial value 80 by 50%

final = (80 × 50 / 100) + 80

final = (80 × .5) + 80

final = 40 + 80

final = 120
