Percentage Increase Calculator
Answer:
= 30% increase
Solution:
Calculate percentage change
from Starting Value = 1.5
to Final Value = 1.95 \[ \dfrac{(\text{Final}-\text{Start})}{|\text{Start}|} \times 100 \] \[ = \dfrac{(1.95 - 1.5)}{|1.5|} \times 100 \] \[ = \dfrac{0.45}{1.5} \times 100 \] \[ = 0.3 \times 100 \] \[ = 30\% \; \text{change} \] \[ = 30\% \; \text{increase} \]
A positive change is an increase.
A negative change is a decrease.

Enter starting value and final value to find percentage increase.

Input whole numbers or decimal numbers in the calculator. You can also use time values to find percentage increase in amount of time. Enter time values in these formats where hh = hours, mm = minutes and ss = seconds:

  • hh:mm
  • mm:ss
  • hh:mm:ss

How to Calculate Percentage Increase

  • Subtract final value minus starting value
  • Divide that amount by the absolute value of the starting value
  • Multiply by 100 to get percent increase
  • If the percentage is negative, it means there was a decrease and not an increase.

Percentage Increase Formula

You can use the percentage increase formula for any percent increase calculation:

\( \text{Percentage Increase} = \)
\( \dfrac{\text{Final Value} - \text{Starting Value}}{\left|\text{Starting Value}\right|} \times 100 \)

Watch the CalculatorSoup® YouTube video How to Calculate Percentage Increase for some example calculations. We'll show you how to find percent increase between two numbers, and also demonstrate how to use the CalculatorSoup Percentage Increase Calculator above.

Example Problem: Percentage Increase

Last year your favorite jeans cost $36 per pair. This year they cost $45 per pair. What is the percentage increase in the price of these jeans from last year to this year?

First, recall the percentage change formula. Percentage Increase = [ (Final Value - Starting Value) / |Starting Value| ] × 100

Plug your numbers into the formula. V2 is 45 and V1 is 36.

45 - 36 = 9
9 / 36 = 0.25
0.25 × 100 = 25%

So the price of your favorite jeans increased by 25% from last year to this year.
