Growth Rate

Growth rate measures percentage change over time in revenue, earnings, cash flow, assets, or investment value.

Growth rate is a fundamental metric in economics and finance that measures the amount of change over a specified period in certain financial characteristics of an entity, such as sales revenue or profits. Typically expressed as a percentage, growth rate is instrumental in assessing the real performance of a company, especially when adjusted for inflation or other economic indicators like the Retail Price Index (RPI).

Compound Annual Growth Rate (CAGR)

CAGR is the mean annual growth rate of an investment over a specified period longer than one year. The formula is:

$$ \text{CAGR} = \left( \frac{V_f}{V_i} \right)^{\frac{1}{n}} - 1 $$
where \( V_f \) is the final value, \( V_i \) is the initial value, and \( n \) is the number of years.

Revenue Growth Rate

This measures the annual increase in sales revenue, a critical indicator of business performance. The formula is:

$$ \text{Revenue Growth Rate} = \left( \frac{\text{Revenue}_{\text{current}} - \text{Revenue}_{\text{previous}}}{\text{Revenue}_{\text{previous}}} \right) \times 100 \% $$

Profit Growth Rate

This assesses the annual increase in net profit. Calculated as:

$$ \text{Profit Growth Rate} = \left( \frac{\text{Profit}_{\text{current}} - \text{Profit}_{\text{previous}}}{\text{Profit}_{\text{previous}}} \right) \times 100 \% $$

Importance

Understanding growth rates is crucial for multiple stakeholders:

  • Investors: Evaluate potential returns and risks.
  • Managers: Make informed strategic decisions.
  • Economists: Gauge economic health and predict future trends.

Review Question

When reviewing Growth Rate, ask where it enters the analysis: source data, adjustment, scenario, discount rate, multiple, terminal value, or sensitivity. If it changes enterprise value, equity value, return, leverage, margin, or comparability, show the bridge instead of burying the effect in a single estimate.
