Measure total return and annualized growth rate (CAGR) between two portfolio values.
Enter values above and click Calculate — results will appear here with the formula explained.
Total return tells you how much an investment grew overall, but it hides timing. A 100% gain in eight years is very different from 100% in two. The compound annual growth rate converts any multi-year outcome into the single steady rate that would produce the same result — the great equalizer that lets a 3-year trade, a 10-year fund holding and a 30-year retirement account speak the same language.
CAGR smooths over volatility — a fund that swings up and down still gets one clean number. It also ignores contributions and withdrawals, so it best describes buy-and-hold positions without cash flowing in or out. Two investments with identical 8% CAGR can feel utterly different if one glided and the other crashed 40% mid-way; CAGR measures destination, never the ride. For the ride, look at maximum drawdown and standard deviation alongside.
Benchmarking is where CAGR earns its keep. Compare against a relevant index (S&P 500 for US large-cap exposure, aggregate bond indices for fixed income), against inflation for real growth, and against fees: a fund showing 9% gross with 1.5% expenses delivers 7.5% to you, while an index fund at 0.05% keeps nearly all of it. Over 30 years, that 1.45-point fee gap compounds into roughly a one-third smaller ending balance — fees are negative CAGR applied relentlessly.
The recovery asymmetry deserves emphasis because it governs risk decisions: losses need larger gains to recover, and the math steepens fast. A 10% loss needs ~11% to recover, 25% needs ~33%, and 50% needs 100%. This is why capital preservation dominates compounding strategy — avoiding a single 30% drawdown matters more than capturing an extra 2% in good years, and why position sizing and diversification are return tools, not just safety tools.
Time-period sensitivity can mislead: CAGR over cherry-picked endpoints tells whatever story the picker wants. A fund measured from a 2009 bottom prints a heroic CAGR; from a 2007 peak, a pedestrian one. Always ask what endpoints frame any quoted CAGR, prefer 10+ year windows spanning full cycles, and distrust any performance claim that won't show rolling-period figures.
Nominal versus real is the final adjustment: subtract inflation to see purchasing-power growth. A 10% nominal CAGR during 4% inflation is ~6% real — still strong, but a different retirement plan than 10% spendable. Run this calculator's result against your era's inflation to keep expectations denominated in groceries, not headlines. Past performance never guarantees future results — this is an educational estimate, not financial advice; consult a qualified professional before investing.
Measure total return and annualized growth rate (CAGR) between two portfolio values. Formula: CAGR = (End ÷ Start)^(1/years) − 1. Example: An account growing from $10,000 to $16,000 over 4 years has a total return of 60%, but a CAGR of (1.6)^(1/4) − 1 ≈ 12.47% per year.

An account growing from $10,000 to $16,000 over 4 years has a total return of 60%, but a CAGR of (1.6)^(1/4) − 1 ≈ 12.47% per year. A fee comparison: the same $10,000 at 9% gross for 30 years reaches ~$132,700, but 1.5% annual fees (7.5% net) reach only ~$87,500 — the fee claims a third of the outcome, which is why expense ratios deserve the same scrutiny as returns.
