# Calculate Ratio in Excel

In this article, we have explained how to calculate the RATIO between two number in Excel. We have used the Excel formula as well as the User defined function in VBA to calculate the RATIO in Excel

RATIO is used to compare two values with each other. In the Excel we don’t have the single function to calculate the ratio.

We have used GCD function of excel to get the Ratio between two numbers. GCD returns the greatest common divisor between two or more numbers.

### Below is the formula which we have used to calculate the Ratio in Excel:

`=B2/GCD(B2:C2) & " : " & C2/GCD(B2:C2)`

We have also created a User defined function in VBA to calculate the Ratio in Excel. Below is the code-

```Function RATIO(first_number As Long, second_number As Long) As String

Application.Volatile

Dim gcd As Long

gcd = Application.WorksheetFunction.gcd(first_number, second_number)

RATIO = first_number / gcd & " : " & second_number / gcd

End Function```

After putting this UDF in the module of Visual Basic Editor, you can put the RATIO function in Excel-

=Ratio(B2,C2)
