Have you ever wondered how to calculate the percentage increase from one number to another? Whether you’re tracking the growth rate of your business or keeping an eye on stock price changes, understanding how to compute percentage increase is an essential skill. This guide will walk you through everything you need to know about calculating percentage increases, accompanied by practical examples and a handy calculator.

Directions for Use
Input and Compute
To get started with calculating percentage increase, you’ll need two key pieces of information: the Starting Value and the Final Value. Simply enter these numbers into their respective fields and press “Calculate.” The calculator will instantly provide you with the percentage increase. You can also press “Enter” on your keyboard to trigger the calculation.
Accepted Input Types
The calculator accepts both whole and decimal numbers. These numbers can be either positive or negative. However, if you need to calculate the percentage increase for fractions, you must first convert these fractions into decimal numbers. Note that if you enter a fraction, the calculator will only consider the portion before the fraction-bar.
Calculating Percentage Increase
General Formula
The percentage increase can be calculated using a straightforward formula:
[ \text = \left( \frac{\text – \text}{|\text|} \right) \times 100 ]
Step-by-Step Breakdown
- Calculate the Increase:
Subtract the Starting Value from the Final Value.
[ \text = \text – \text ]
- Convert to Decimal:
Divide the increase by the absolute value of the Starting Value to get the decimal form of the increase.
[ \text = \frac{\text}{|\text|} ]
- Convert to Percentage:
Finally, multiply the decimal increase by 100 to get the percentage increase.
[ \text = \text \times 100 ]
Important Note
In step 1 of the algorithm and in the numerator of the percentage increase formula, you use the numbers as they are, including their signs. In step 2, as well as in the denominator of the percentage increase formula, you use the absolute value of the starting number. Thus, there is a possibility that the final Percentage Increase value might be negative. This occurs if the starting value is greater than the final value, indicating a percentage decrease instead.
Practical Examples
Example 1: Calculating Percentage Increase from -10 to 68
Let’s calculate the percentage increase from -10 to 68:
- Starting Value: -10
- Final Value: 68
[ \text{|Starting value|} = |-10| = 10 ]
Following the steps above:
[ \text = 68 – (-10) = 78 ]
[ \text = \frac = 7.8 ]
[ \text = 7.8 \times 100 = 780% ]
Alternatively, using the formula:
[ \text = \left( \frac \right) \times 100 = 780% ]
Example 2: Calculating Growth Rate in Terms of Company’s Revenue
Imagine you’re starting a small company and need to produce a financial report to gauge how quickly your company is growing. Your company generated $1265.70 in revenue in its first month and $1879.30 in August. You set a goal to achieve a 30% revenue growth rate within six months of operation.
- Starting Value: $1265.70
- Final Value: $1879.30
[ \text = 1879.30 – 1265.70 = 613.60 ]
[ \text = \frac \approx 0.48 ]
[ \text = 0.48 \times 100 = 48% ]
So, within the first six months, your company achieved a 48% revenue growth rate, significantly exceeding your initial goal of 30%.
Example 3: Calculating Price Increase of Stock Shares
Suppose your friend John bought stock shares priced at $15.65 per share on June 1st. By July 1st, the price increased to $16.70 per share.
- Starting Value: $15.65
- Final Value: $16.70
[ \text = 16.70 – 15.65 = 1.05 ]
[ \text = \frac \approx 0.07 ]
[ \text = 0.07 \times 100 = 7% ]
Therefore, the share value percentage increase amounts to 7%.
