What Is Absolute Difference?

It is the accurate difference of two numbers.

Absolute Change Formula:

Our absolute change calculator uses the absolute difference formula to calculate whether the difference is positive or negative. If your goal also comes up with the manual calculations, stick to the following equation:

X = b−a


  • X = Absolute change
  • b = Initial value
  • a = Final value

How To Calculate Absolute Difference?

Suppose Reshaeel measured his height as 5.2 feet on a certain day. After a tenure of 6 months, his height increased to 5.9 feet. What is the difference in height?


Using the absolute change formula:

X = b−a

X = 5.9 – 5.2

X = 0.7 feet

Can Absolute Change Be Negative?

Definite Yes! Absolute change never means that the difference will always be a positive number. If the final recorded value gets smaller than the initial one, the resultant numeral will be a negative absolute difference.

For instance, you may insert the final number as a smaller one in our absolute change calculator and it will certainly show you the difference.
