A 60% total return looks great until you find out it took 12 years to earn. Annualizing the number puts every investment on the same footing.
Step 1: Total Return
Total return = (Ending value − Starting value) / Starting value × 100
Example: $10,000 grows to $16,000. Total return = 60%.
Step 2: Time
Note how many years you held it. Partial years are fine — use the fraction.
Step 3: Plug Into the CAGR Formula
CAGR = (Ending / Starting)^(1 / years) − 1
For $10,000 → $16,000 over 5 years:
(16,000 / 10,000)^(1/5) − 1 = 1.6^0.2 − 1 ≈ 0.0986 → 9.86% per year
Step 4: Compare
Now you can compare against benchmarks:
- S&P 500 long-term: ~10% nominal, ~7% real
- Investment-grade bonds long-term: ~4–5%
- Cash savings (high-yield): ~4–5% today, lower historically
Step 5: Sanity Check
If your "annualized" return is much higher than the broad market, ask why — is it skill, leverage, lucky timing, or unmeasured risk? High annualized returns rarely persist forever.
The Easy Version
Skip the math: plug your numbers into the CAGR Calculator or the ROI Calculator. Both compute total and annualized in one step.
When Annualized Doesn't Apply
If you made multiple deposits and withdrawals, simple CAGR understates or overstates the truth. For irregular cash flows, time-weighted return or internal rate of return (IRR) are the right tools — most brokerages report these on your statements.
Bottom Line
Total return tells you what you earned. Annualized return tells you how fast — and is the only fair way to compare investments held for different periods.
Frequently Asked Questions
How do you convert a total return into an annualized return?
First calculate total return as (ending value − starting value) ÷ starting value, then apply the CAGR formula: (ending value ÷ starting value) raised to the power of (1/years), minus 1. For example, $10,000 growing to $16,000 over 5 years is a 60% total return, but annualizes to roughly 9.86% per year. Annualizing lets you fairly compare investments held for different lengths of time.
Why is annualized return a better comparison tool than total return?
A 60% total return earned over 2 years reflects a much stronger performance than the same 60% earned over 12 years, and total return alone doesn't reveal that difference. Annualizing puts every investment on the same per-year footing, which is essential when comparing results across different holding periods. It's a standard way to evaluate whether a return is actually attractive relative to typical benchmarks.
What should I do if my investment had multiple deposits and withdrawals, not just one purchase?
In that case, simple CAGR can understate or overstate your actual results, so time-weighted return or internal rate of return (IRR) are generally the more appropriate tools, since they account for cash flows occurring at different times. Most brokerage statements already calculate and report these figures for accounts with irregular activity. For accounts with only a single purchase and sale, straightforward CAGR remains the simplest and most accurate approach.
