Understanding changes in contributions—whether for retirement plans, savings, or employee benefits—is essential for tracking financial progress. The Contribution Increase Calculator helps you calculate the percentage increase from an original contribution amount to a new one. This tool is valuable for both individuals and organizations seeking to monitor their financial improvements.
Formula
The formula used for calculating contribution increase is:
CI = ((NC − OC) / OC) × 100
Where:
NC = New Contribution
OC = Original Contribution
How to Use
- Enter the original contribution amount in the “Original Contribution” input field.
- Enter the new contribution amount in the “New Contribution” input field.
- Click on the “Calculate” button.
- The percentage increase will be shown below the button.
Example
Suppose your original contribution was $200 and your new contribution is $250.
Using the formula:
((250 − 200) / 200) × 100 = 25%
So, the contribution increase is 25%.
