Understanding and Calculating Yearly Growth Rate

The yearly growth rate, often referred to as the Compound Annual Growth Rate (CAGR), is a crucial metric used to assess the performance of an investment, business, or any other quantity that changes over time. It represents the average annual rate at which a value has grown over a specified period, assuming that the growth has been compounded each year. CAGR smooths out volatility and provides a more stable indicator of growth compared to year-over-year fluctuations.

Why is Yearly Growth Rate Important?

CAGR is vital for several reasons:

  • Investment Analysis: It helps investors compare the historical performance of different assets on an apples-to-apples basis.
  • Business Performance: Companies use CAGR to track revenue growth, customer acquisition, or market share expansion over several years.
  • Forecasting: While it's a backward-looking metric, CAGR can inform future projections when past trends are expected to continue.
  • Simplification: It provides a single, easily understandable figure representing average annual growth, simplifying complex data over multiple periods.

How to Calculate Yearly Growth Rate (CAGR)

The formula for calculating the Compound Annual Growth Rate is as follows:
CAGR = (Ending Value / Starting Value)^(1 / Number of Years) – 1

Let's break down the components:

  • Starting Value: The initial value of the investment or metric at the beginning of the period.
  • Ending Value: The final value of the investment or metric at the end of the period.
  • Number of Years: The total duration of the period in years.
The result is typically expressed as a percentage.

Example Calculation

Suppose you invested $1,000 in a stock at the beginning of 2019, and by the end of 2023, its value had grown to $1,500. The total period is 5 years (2019, 2020, 2021, 2022, 2023).

  • Starting Value = $1,000
  • Ending Value = $1,500
  • Number of Years = 5

Using the formula:
CAGR = ($1,500 / $1,000)^(1 / 5) – 1
CAGR = (1.5)^(0.2) – 1
CAGR = 1.08447 – 1
CAGR = 0.08447

To express this as a percentage, multiply by 100:
Yearly Growth Rate = 0.08447 * 100 = 8.45%

This means your investment grew at an average compounded rate of 8.45% per year over the 5-year period. The calculator above automates this process for you.
