CAGR — compound annual growth rate — is the smoothed, constant annual rate at which a value would have grown to get from its starting point to its ending point. It strips out the year-to-year volatility and gives you a single, clean growth rate that is easy to compare across companies, investments, or time periods.
CAGR is the metric investors and founders reach for when describing growth, because raw multi-year growth can be misleading. Going from $100k to $250k is 150% total growth — but spread over four years that is a much more modest 25.7% per year. CAGR answers the question "how fast did this really grow, per year?" which is exactly what matters in a pitch deck, a board update, or an investment comparison.
CAGR = ( (Ending Value ÷ Beginning Value) ^ (1 ÷ Years) ) − 1
Multiply by 100 to express it as a percentage. The exponent of 1 ÷ Years is what converts total growth into a per-year compounded rate.
Revenue grows from $100,000 to $250,000 over 4 years:
So despite 150% total growth, the honest annual growth rate to put in front of investors is about 25.7%.
CAGR shows up everywhere in startup finance: revenue growth in your pitch deck, user growth in board updates, market-size projections, and investor return expectations. Using it correctly signals financial literacy; using it loosely (or confusing it with total growth) is a credibility risk in front of sophisticated investors.
