CAGR Calculator
A compound annual growth calculator from start value, end value, and years.
It measures the constant annual rate that grows start to end over the horizon.
Use it when you need an annualised growth rate — not a single-period ROI.

CAGR Calculator
CAGR (compound annual growth rate) — the constant annual rate that grows a start value to an end value over a set number of years. Sibling to simple ROI (which is not annualised).

Compound annual growth
CAGR, total return, and growth multiple.
Equations
- CAGR = (Final ÷ Initial)1/Years − 1
- TotalReturn = Final ÷ Initial − 1
- GrowthMultiple = Final ÷ Initial
How this is calculated
- CAGR (compound annual growth rate) — the smoothed annual rate that compounds Initial to Final over Years
- Total return — period gain as a fraction of Initial (not annualised)
- Growth multiple — Final ÷ Initial (e.g. 1.61×)
Illustrative — not financial advice. Distinct from ROI (simple period return) and from LTV:CAC payback (customer months).
