Annualized rate of return
Definition
Annualized rate of return
The annualized rate of return turns total investment gains into one yearly figure, so you can compare holdings of very different lengths on a single scale. It answers one question: what steady yearly rate would have produced the same ending balance?
Also called the compound annual growth rate (CAGR), it assumes the gain repeats at one constant pace every year. The formula is (Ending value / Beginning value)^(1/N) − 1, where N is the number of years held.
That single number is the whole point. Without it, a 61% gain booked over five years and a 14% gain booked over one year sit on incompatible scales, and the eye picks the bigger headline every time.
The U.S. Securities and Exchange Commission requires standardized annualized figures in its guidance on mutual fund performance. The CFA Institute’s Global Investment Performance Standards (GIPS) ask the same of managers publishing composite results.
Key takeaways
- Annualized rate of return standardizes multi-year gains into one yearly figure, so different holding periods compare fairly.
- The formula uses geometric compounding: (Ending value / Beginning value)^(1/N) − 1.
- Regulators and the GIPS standards require it for mutual fund and investment manager reporting.
- It flattens volatility, so one strong year cannot distort a comparison that spans decades.
- Time-weighted and money-weighted variants both exist, each suited to a different cash-flow pattern.
How it works
Annualized rate of return uses the geometric mean, not the arithmetic mean. It takes the total growth factor across the whole holding, then asks what constant yearly rate, compounded N times, lands on exactly the same ending value.
Compounding is the whole story. A $10,000 investment that grows to $16,105 over five years shows a 61% total gain, yet its annualized figure is 10% — the yearly rate that, compounded five times, produces that ending balance.
The gap widens with volatility. A holding that falls 50% then rises 100% has an arithmetic average of +25% a year, yet its annualized return is 0%: you end exactly where you started. Geometric math refuses to flatter a bumpy path.
| Metric | What it measures | Best used for |
|---|---|---|
| Annualized rate of return | geometric yearly gain across the full holding | comparing periods of different lengths |
| Average rate of return | simple arithmetic mean of the yearly results | quick estimates and single-year reporting |
| Total rate of return | cumulative gain from the first day to the last | raw performance reporting |
| Time-weighted return | growth per dollar, with cash flows stripped out | judging a manager’s skill |
| Money-weighted return, or internal rate of return (IRR) | return including the timing of deposits and withdrawals | judging an investor’s own outcome |
N does not have to be a whole number. A 14-month holding runs on N = 1.167 and a 90-day holding on N = 0.247 — the formula handles either one without complaint.
Whether you should annualize is a separate question. Scaling a three-month gain across a full year assumes the next nine months repeat it, which is why fund disclosures publish sub-year periods as raw returns instead.
Analysts adjust the result before drawing conclusions. A 10% annualized return means far less when the prevailing interest rate on cash sits near 5%, and inflation takes another bite from what survives.
Examples
Fund managers, index providers and private funds all publish annualized figures because holding periods never match. The cases here show how far a single year can drift from a full decade, and why the annualized number is usually the one worth reading.
Berkshire Hathaway Class A stock has compounded near 20% annualized since 1965. That gives shorter track records something to stand against — six decades of results reduced to one comparable figure.
The S&P 500 returned roughly 26% in 2023, but its trailing 10-year annualized figure sat closer to 12% — a reminder that one strong year does not make a strong decade.
Investment-grade bonds have delivered 4–6% annualized over recent decades, well below US equity indices but with far smaller drawdowns. That gap is why diversified portfolios hold both.
Real estate, private equity and venture funds report annualized net returns too. Holding periods often stretch 7–10 years, and IRR math answers a different question than a public-market figure does.
Managers reporting under GIPS must publish figures net of fees, which stops a gross number from flattering a record that investors never actually earned.
The Corporate Finance Institute works a clean case in its annualized total return resource: $50,000 invested in 2020, exited at $75,000 in 2023, earns roughly 14.5% annualized on a 50% cumulative gain.
Try the comparison the metric was built for. A three-month holding up 6% and a ten-year holding up 180% look nothing alike, until you annualize them: the first runs at about 26% a year, the second at about 10.8%.

FAQ
Most questions about the annualized rate of return come down to three things: how it differs from a simple average, when you can fairly use it, and what it includes. Here are the short answers.
What is the difference between annualized return and average return?
Annualized return uses geometric compounding, while average return takes a simple arithmetic mean of the yearly results. Over volatile periods the arithmetic average overstates performance, because it ignores the drag a loss puts on the base the next gain works from.
Is annualized return the same as CAGR?
Yes, for a single investment with no money moving in or out. Compound annual growth rate is the common name for the same geometric formula, though fund reporting usually prints it as annualized return.
Can annualized return be negative?
It can. If the ending value sits below the starting value, the annualized figure turns negative and shows the yearly rate of decline across the holding period.
How many years do you need to annualize?
Any period longer than a year annualizes cleanly, and N can be fractional above that. Shorter windows are normally published as raw returns, because stretching a few weeks across twelve months assumes a pace that rarely holds.
Does annualized return include dividends?
Only when the figure is published as a total return, which folds in reinvested dividends and interest, while price-only annualized returns leave them out.
