How to Calculate Ratio of 3 Numbers in Excel (3 Quick Methods)

The calculating ratio of numbers can be very helpful in analyzing data by comparison. Excel doesn’t have any built-in feature or function that can be used to calculate the ratio of 3 numbers. However, we can use formulas to fill that void. In this article, I will discuss 3 formulas that you can use to calculate the ratio of 3 numbers in Excel with ease.

3 Useful Methods to Calculate Ratio of 3 Numbers in Excel

I’m going to use the following dataset having four columns in total. I’ve used 3 columns named Number 1, Number 2, and Number 3. In these three columns, I’ve inserted some random numbers. In the fourth column called Ratio, I will use formulas to calculate the ratio of 3 numbers from Number 1, Number 2, and Number 3 columns.

1. Using Basic Division to Calculate Ratio of 3 Numbers

We can calculate the ratio of 3 numbers using the basic division formula quite easily.

All you need to do is,

❶ Insert the following formula in cell E5.

="1:"&C5/B5&":"&D5/B5

❷ After that press ENTER.

Formula Breakdown

If we divide all 3 numbers by the first number, then we get the ratio of the 3 numbers with respect to the first number. The above formula is written based on this concept.

  • B5, C5, D5 represent the Number 1, Number 2, and Number 3
  • Dividing B5 with B5 always produces 1. Thus, I kept 1 as the default ratio of the Number 1.
  • C5/B5 calculates the ratio of Number 2.
  • D5/B5 calculates the ratio of Number 3.
  • Finally, each ratio is separated by colons (:) from one another.

This formula displays up to 15 decimal places for the fraction ratios. Which you may not need at all.

In the next method, I have shown how to round off fraction ratio numbers.

2. Calculating Ratio of 3 Numbers with TEXT Function

In this method, I will show you to calculate the ratio of 3 numbers with the TEXT function. The TEXT function allows us to add formats to the numbers.

In the previous method, the fraction ratio numbers were having long trails of decimal places. To trim those trailing decimal places I’m using the TEXT function here. I will round off the fraction ratio number to 2 decimal places.

❶  At first, insert the following formula in cell E5.

="1:"&TEXT(C5/B5,"0.00")&":"&TEXT(D5/B5,"0.00")

❷ After that press ENTER.

Formula Breakdown

  • B5, C5, D5 represent the Number 1, Number 2, and Number 3
  • Dividing B5 with B5 always produces 1. Thus, I kept 1 as the default ratio of the Number 1.
  • C5/B5 calculates the ratio of Number 2.
  • D5/B5 calculates the ratio of Number 3.
  • Each ratio is separated by colons (:) from one another.
  • The TEXT function rounds off the fraction numbers up to 2 decimal places. This is specified by “0.00”.

3. Using GCD Function to Calculate Ratio of 3 Numbers

If you want to calculate the ratio of 3 numbers in terms of integer numbers, you can use the GCD function.

In the previous two methods, I have shown you calculate the ratio of 3 numbers by dividing each number by the first number.

But here I will calculate the ratio of 3 numbers by dividing each number by the Greatest Common Divisor (GCD) of the other two numbers.

For that,

❶ Insert the following formula in cell E5.

=B5/GCD(B5,C5)&":"&C5/GCD(B5,C5)&":"&D5/GCD(C5,D5)

❷ After that press ENTER.

Formula Breakdown

  • B5, C5, D5 represent the Number 1, Number 2, and Number 3
  • The GCD function returns the Greatest Common Divisor of two numbers.
  • B5/GCD(B5,C5) returns the proportion of Number 1.
  • C5/GCD(B5,C5) returns the proportion of Number 2.
  • D5/GCD(C5,D5) returns the proportion of Number 3.
  • Finally, each ratio is separated by colons (:) from one another.
