Use the Increase Ratio Calculator to find the increase ratio (total increase ÷ initial value). In the “Final Value” tab, you can enter any 2 of the values (initial value, final value, total increase, or increase ratio) and calculate the others. You can enter the increase ratio as a decimal or as a percent.

Increase Ratio Formula
The following formula is used to calculate the Increase Ratio.
IR = TI / IV
- Where IR is the Increase Ratio
- IV is the initial value
- TI is the total increase (final value − initial value)
To calculate the increase ratio, divide the total increase by the initial value. To express the result as a percent increase, multiply the ratio by 100%.
How to Calculate Increase Ratio?
The following example problems outline how to calculate the Increase Ratio.
Example Problem #1:
- First, determine the initial value.
- The initial value is given as: 5.
- Next, determine the final value.
- The final value is provided as: 15.
- Finally, calculate the total increase (TI = final − initial), then compute the Increase Ratio: IR = TI / IV (multiply by 100 to express it as a percent).
IR = (FV − IV) / IV
The values given above are inserted into the equation below and the solution is calculated:
TI = 15 − 5 = 10; IR = 10 / 5 = 2.0000 (decimal) = 200.00%
Example Problem #2:
For this problem, the variables required are provided below:
initial value = 6
final value = 8
Test your knowledge using the equation and check your answer with the calculator above.
IR = (FV − IV) / IV = (8 − 6) / 6 = ?
