How It Works
Enter a starting value, ending value, and number of years held. The calculator finds the compound annual growth rate that connects those two points. It also shows cumulative multiplier and total return percentage so you see annualized and absolute performance together. Example: ten thousand dollars growing to twenty thousand over five years implies about fourteen point eight seven percent CAGR. Use CAGR to compare funds, stocks, or business metrics on equal footing regardless of calendar path. Update inputs after each year end review to track whether personal savings rate and market returns keep you on plan toward FIRE or college funding targets.
CAGR smooths volatile year by year returns into one constant rate. A portfolio that gained forty percent then lost twenty percent still reports a single CAGR over the full window. Compare that figure against benchmark indices quoted on total return basis. Pair CAGR with total return percentage when explaining results to partners who focus on dollar growth rather than annualized rates. Short windows under three years can produce extreme CAGR from one lucky year; label those results as preliminary. Export multiplier and total return when building slide decks for investment policy reviews.
CAGR Finder recalculates instantly as you adjust any input. Test optimistic scenarios by increasing the end value and conservative cases by lowering it. The multiplier and total return percentage update alongside CAGR, giving you three lenses on the same growth story. For presentations, export the numbers into a spreadsheet and add your own commentary on assumptions and market context.
Use CAGR Finder whenever inputs change: after market moves, new contributions, or revised personal assumptions. Bookmark the page for quick reruns without installing software.

The Formula
CAGR = (endValue / startValue) ^ (1 / years) - 1
multiplier = endValue / startValue
totalReturnPct = (multiplier - 1) × 100
CAGR assumes constant compounding once per year. Real paths fluctuate. Zero start value is invalid. For flows during period use money weighted or time weighted return tools instead. Multiplier and total return display alongside annualized rate for complete picture. Educational estimates only. Consult a qualified professional before major financial decisions.

FAQ
What is CAGR?
CAGR is compound annual growth rate: the steady yearly rate that would grow start value to end value with annual compounding. It answers how fast something grew per year on average. Mutual fund factsheets and index providers headline CAGR over standard periods. Business analysts use the same math for revenue or user growth. CAGR is backward looking unless you supply projected end values in a spreadsheet copy. Always state the calendar start and end dates alongside CAGR when presenting to advisors.
How is CAGR calculated?
Formula: CAGR equals end value divided by start value, raised to one divided by years, minus one. Multiplier equals end divided by start. Total return percent equals multiplier minus one, times one hundred. Example: twenty thousand divided by ten thousand over five years uses fifth root of two minus one. Fractional years are supported when holding period includes partial years between dates. Zero or negative start or end values break the formula because roots of negative ratios are undefined in real planning contexts. Verify year count matches calendar days divided by three hundred sixty five when converting date based holding periods instead of typing whole years only. Leap years and partial months affect fractional year precision when comparing brokerage statement CAGR to this calculator output.
What are the limitations of CAGR?
CAGR hides path risk. Two investments with identical CAGR can have wildly different drawdown profiles. A smooth eight percent every year feels different from plus thirty minus ten alternating years even if CAGR matches. Use Maximum Drawdown and Sharpe Sortino tools alongside CAGR for risk context. Long horizon CAGR on broad indices understates sequence risk for retirees taking withdrawals. CAGR also assumes reinvestment at the same rate, which may not match dividend spending behavior in income portfolios.
Does CAGR account for risk?
CAGR does not embed risk, taxes, fees, or inflation. A ten percent nominal CAGR with three percent inflation is roughly seven percent real using approximate Fisher math. Subtract advisory fees and fund expense ratios mentally when comparing personal CAGR to index benchmarks quoted gross of frictions. Leveraged products can show attractive CAGR over short windows while long run CAGR collapses due to volatility drag. Always read fund CAGR net of fees on official factsheets.
Can CAGR be used for non-investment metrics?
Yes. CAGR applies to revenue, subscribers, GDP, or any positive metric over time. The math is identical. When start value is zero, CAGR is undefined because division by zero breaks the formula. Use absolute growth or year one base instead for startup metrics. Per share metrics should use split adjusted prices when computing stock CAGR manually before entering this tool.
How do I use this CAGR calculator on phone or tablet?
CAGR Finder runs entirely in your mobile browser with the same formulas as desktop. Just open the page on your phone or tablet, enter your values, and results appear instantly. Optional localStorage may remember inputs on your device when enabled in browser settings.
Where is my data stored when I use CAGR Finder?
Nowhere on our servers. Calculations execute locally in your browser. Optional localStorage saves form fields on your device only and never transmits portfolio numbers over the network.
Should I rely on CAGR Finder for tax or legal decisions?
No. CAGR Finder provides educational math only. Tax law, account rules, and personal circumstances vary. Consult a qualified tax or legal professional before transactions with material consequences.
