Percentage Increase Calculator

How do you calculate Percentage Increase manually?

You can calculate percentage increase by finding the difference between the new value and original value, dividing that increase by the original value, and multiplying the result by 100.

Formula:

Step by step guide:

1. Subtract the original value from the new value to find the absolute increase.
2. Divide the absolute increase by the original value.
3. Multiply the result by $100$ to convert the decimal into a percentage.

Practical Example:

Suppose a product's price rises from 80$to 100$.

$\text{Absolute Increase} = 100 - 80 = 20$

Now divide the increase by the original price:

$\frac{20}{80} = 0.25$

Multiply by $100$:

$0.25 \times 100 = 25$

The price increased by 25%. Always use the original value as the denominator because percentage increase measures growth relative to the starting amount.

How do I calculate percentage increase in Excel?

In Excel, enter the original value in cell A2 and the new value in B2. Then use =(B2-A2)/A2 and format the result as Percentage. For example, if A2 contains $80$ and B2 contains $100$, Excel returns 25%. This formula measures the relative increase from the starting value to the final value.
