How to Calculate CAGR? A Simple Guide for Smart Growth Analysis
What Is CAGR — and Why It Matters
As a Marketer, one of the most valuable metrics for analyzing growth—be it in revenue, prescriptions, or market expansion—is the Compound Annual Growth Rate (CAGR). It translates volatile performance data into a smooth, comparable annual growth rate, giving you clarity and credibility in strategy discussions.
How to Calculate CAGR (with Formula)
Here’s the standard formula:
-
EV = Ending Value
-
BV = Beginning Value
-
n = Number of years
— as defined by Investopedia and Wikipedia InvestopediaWikipedia
Example:
If your total sales grew from $5M to $10M over 3 years:
This means your sales grew at an annualized rate of ~26%, smoothing out year-to-year fluctuations.
Tips for Using CAGR
-
Best for tracking multi-year growth metrics and setting realistic targets.
-
It doesn't reflect short-term volatility or risks—pair with other metrics where needed Investopedia.
-
Use formula tools in Excel:
=(EV/BV)^(1/n)-1or=RRI(n, BV, EV)for convenience WikipediaMicrosoft Support.
Applying CAGR in the Pharmaceutical Industry
CAGR is especially insightful in pharma, where launches, patent cliffs, or market trends impact long-term growth.
