Improvement Percentage Calculator with Formula

This tool calculates the percentage improvement using the

  • Final Value
  • Initial Value


Improvement Percentage = ((Final Value – Initial Value)​/Initial Value) × 100

How to calculate Improvement Percentage

Calculating the improvement percentage helps you understand how much progress you’ve made from an initial value to a final value. Here’s a step-by-step guide on how to calculate the improvement percentage:

Identify the Initial and Final Values:

Determine the starting value (initial value) and the ending value (final value) for the parameter you are measuring.

Calculate the Difference

Subtract the initial value from the final value to find the change (difference). Difference = Final Value − Initial Value

Divide the Difference by the Initial Value

To find the relative change, divide the difference by the initial value.
Relative Change = Difference/Initial Value

Multiply by 100 to Get the Percentage

Convert the relative change to a percentage by multiplying by 100. Improvement Percentage = (Difference/Initial Value​) × 100

Example Calculation

Assume you want to calculate the improvement percentage of your monthly savings, which increased from $200 to $300.

  1. Initial Value: $200
  2. Final Value: $300
  3. Calculate the Difference:
    300 – 200 = 100
  4. Divide the Difference by the Initial Value:
    100/200 = 0.5
  5. Multiply by 100 to Get the Percentage:
    0.5 x 100 = 50%

Therefore, the improvement percentage is 50%.


A percentage improvement calculator simplifies the process of determining how much you have improved over a specific period.

By inputting your initial and final values, the calculator computes the percentage change, providing a clear and concise measure of your progress.

This calculation is particularly useful in various fields such as education, finance, health, and project management, where tracking improvement is crucial for motivation and strategy adjustment.
