You enter a beginning value, an ending value, and the number of years between them. The tool applies the standard CAGR formula: (Ending / Beginning)^(1/Years) − 1. It also computes total percentage growth and dollar change. CAGR assumes smooth compounding and ignores any interim deposits, withdrawals, or volatility — it is a backward-looking summary metric, not a forward prediction.
Not exactly. CAGR is a geometric mean that accounts for compounding, while a simple arithmetic average of yearly returns can be misleading. CAGR tells you the single steady rate that would produce the same end result — it is generally more useful for comparing investments.
Yes. CAGR is commonly used to express revenue, earnings, or user growth over multiple years. It is especially useful in pitch decks and annual reports because it normalizes uneven year-over-year changes into one comparable figure.
CAGR only looks at the start and end points. Two investments can have the same CAGR but very different risk profiles. If volatility matters to you (and it usually does), pair CAGR with standard deviation or max drawdown for a fuller picture.
No. CAGR is purely backward-looking. Past growth rates do not guarantee future performance. Use CAGR to compare historical performance, not to forecast.
It depends on the asset class and time period. The S&P 500 has historically returned roughly 7–10% CAGR (inflation-adjusted vs. nominal) over long periods. A "good" CAGR also depends on the risk taken — higher returns typically come with higher volatility.
