What CAGR actually tells you
Real investments almost never grow at the same rate two years running — they surge, stall, and dip. CAGR answers a simpler question: if the growth from your beginning value to your ending value had happened at one constant rate every year, what would that rate be? By collapsing a messy, multi-year journey into a single annualized figure, it lets you line up a 3-year holding against a 10-year one and compare them honestly — something a raw total return can’t do.
The CAGR formula
CAGR = (Ending ÷ Beginning)(1 / years) − 1
Worked example: an investment grows from$10,000 to $16,000 over5 years. That’s (16,000 ÷ 10,000)1/5 − 1 = 1.60.2 − 1 ≈ 0.0986, or a CAGR of about9.86% per year — even though the total growth was 60%.
What makes this calculator different
- More than just the rate. We don’t stop at the CAGR percentage — we also surface the total growth over the whole period, so you see both how fast and how much in one place.
- The growth multiple, spelled out. We show how many times your money multiplied (e.g. a 1.6× growth multiple), which is often more intuitive than a percentage when sizing up a long horizon.
- Three inputs, nothing to fuss over. Beginning value, ending value, and years — no rate guessing or compounding-frequency settings. CAGR is annualized by definition.
- Shareable. Every input is saved in the link, so you can send a scenario to anyone.
Frequently asked questions
What is CAGR and how do I calculate it?+
CAGR — compound annual growth rate — is the single steady yearly rate that would take a starting value to an ending value over a given number of years. You calculate it with CAGR = (Ending ÷ Beginning)^(1 ÷ years) − 1. For example, if an investment grows from $10,000 to $16,000 over 5 years, that’s (16,000 ÷ 10,000)^(1/5) − 1 ≈ 0.0986, or about 9.86% per year. It answers the question, “If this had grown at one constant rate every year, what would that rate be?”
Why use CAGR instead of the average annual return?+
A simple average ignores compounding and overstates the return of anything volatile. Imagine a fund that gains 50% one year and loses 50% the next: the simple average is 0%, but you’ve actually lost money — $100 becomes $150, then $75. CAGR captures this correctly because it works off the beginning and ending values, baking compounding in. The more a return bounces around, the more a simple average flatters it, which is exactly why CAGR is the fairer single number for comparing investments.
What is a good CAGR?+
It depends entirely on the asset class and the risk taken — a safe bond and a small-cap growth stock should not be held to the same bar. As a rough reference, the long-run total return of the U.S. stock market (the S&P 500) is often cited at roughly 10% per year before inflation. Treat that as a commonly quoted historical benchmark, not a guarantee or a target you should expect: it’s an average across decades that includes deep crashes and long booms. A “good” CAGR is one that beats a comparable, similarly risky alternative.
What’s the difference between CAGR and total return?+
Total return is the overall percentage change from start to finish — the whole gain stacked into one number, regardless of how long it took. CAGR spreads that same growth evenly across each year as an annual rate. For example, a 60% total return over 5 years is a 60% total return, but only about a 9.86% CAGR. Total return tells you how much you made; CAGR tells you how fast, which is what lets you compare investments held for different lengths of time.
What are CAGR’s limitations?+
CAGR only looks at the first and last values, so it completely ignores everything that happened in between. It says nothing about volatility — a smooth climb and a terrifying rollercoaster can share the exact same CAGR. It also assumes a single lump sum left untouched, so it doesn’t account for interim cash flows like additional deposits, withdrawals, or reinvested dividends paid out along the way. Use CAGR to summarize and compare growth, but pair it with a look at the path and the risk before drawing conclusions.
Disclaimer: CAGR ignores volatility and the path your investment actually took to get from start to finish, and past growth doesn’t guarantee future results. This calculator is for educational purposes only and is not financial advice.
