Enter up to 5 different ratios into the Average Ratio Calculator. The calculator will evaluate and display the Average Ratio. Enter the ratios in the form ( 2:3 = 2/3).

Average Ratio Formula

The following formula is used to calculate the Average Ratio. 

AR = R1+R2+RX / X
  • Where AR is the Average Ratio
  • R1…RX is up to 5 different ratios 
  • X is the number of ratios entered

How to Calculate Average Ratio?

The following example problems outline how to calculate Average Ratio.

Example Problem #1:

  1. First, determine the up to 5 different ratios.
    • The up to 5 different ratios is given as: 1/4, 5/2, 6/10, 7/3.
  2. Finally, calculate the Average Ratio using the equation above: 

AR = R1+R2+RX / #X

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

AR = (1/4+5/2+6/10+7/3) /4 = 1.42:1


Example Problem #2: 

For this problem, the variables required are provided below:

up to 5 different ratios = 2/1,3/1,5/2

Test your knowledge using the equation and check your answer with the calculator above.AR = R1+R2+RX / #X = ?
