Enter the initial value and the final value into the Increase Ratio Calculator. The calculator will evaluate and display the Increase Ratio. 

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

To calculate the increase ratio, divide the total increase by the initial value.

How to Calculate Increase Ratio?

The following example problems outline how to calculate the Increase Ratio.

Example Problem #1:

  1. First, determine the initial value.
    • The initial value is given as: 5.
  2. Next, determine the final value.
    • The final value is provided as: 15.
  3. Finally, calculate the Increase Ratio using the equation above: 

IR = (V1-V2)/V1 * 100

The values given above are inserted into the equation below and the solution is calculated:

IR = (10)5 * 100 = 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 = (V1-V2)/V1 * 100 = ?
