CAGRCompound Annual Growth Rate (CAGR)The steady yearly growth rate that would take an investment from its starting value to its ending value, with gains compounding. Example: $1,000 growing to $2,000 over 10 years is a CAGR of about 7.2%. It hides the ups and downs along the way, which matters for a volatile asset like Bitcoin.

Historical, not a forecast. This replays past data. It does not predict what happens next.

Bitcoin's historical returns are extraordinary and are not expected to continue at the same rate. This tool shows historical data only. No investment strategy is guaranteed.

What this tool assumes
  • BTC uses month-end closes generated at every build from the site's CoinMetrics snapshot (data/btc.json): semiannual points before 2017, quarterly after. Data through 2026-09-19.
  • The SPY total-return series (dividends reinvested) is hand-maintained and may end several months before the BTC series; past its last point the tool holds it flat, which slightly understates the S&P side for the most recent months.
  • Dividends for S&P 500 are reinvested; Bitcoin has no dividends.
  • CAGR is computed on total contributed dollars, which is approximate when a monthly DCA is added (not a money-weighted return).
