What is Relative Rate of Change?

Relative rate of change expresses the magnitude of change relative to a starting value. It is particularly useful when comparing changes in different contexts or when the initial values are significantly different. Unlike absolute change, which only shows the raw difference, relative rate of change provides a proportional perspective.

Formula for Relative Rate of Change

The formula is as follows:

Relative Rate of Change = ((Final Value - Initial Value) / |Initial Value|) * 100

Where:

  • Final Value: The value at the end of the period.
  • Initial Value: The value at the beginning of the period.
  • |Initial Value|: The absolute value of the initial value.

The absolute value ensures that the denominator is always positive, providing a consistent way to interpret the change, regardless of the sign of the initial value.

How to Use the Relative Rate of Change Formula

Let's walk through an example:

  1. Identify the Initial Value: Suppose a company's revenue was $100,000 last year.
  2. Identify the Final Value: This year, the revenue is $120,000.
  3. Apply the Formula:

    ((120,000 - 100,000) / |100,000|) * 100 = 20%

  4. Interpret the Result: The company experienced a 20% relative increase in revenue.
