Choose the measure that matches the entered evidence. Endpoint CAGR needs actual beginning/ending values and elapsed time, with no external flows. Money-weighted return also needs every deposit and withdrawal with its timing. Neither reconstructs missing account history.

Measurement

CAGR is the constant annual rate connecting the entered endpoints. The dashed path is illustrative; no intermediate history, arithmetic average or risk grade is inferred.

Money-weighted return uses the actual initial value, signed investor cash flows and actual terminal receipt. Deposits are negative; withdrawals are positive. Cash-flow markers are not an account-value history.

Cash-flow schedule

Actual/365 divides actual elapsed UTC calendar days by365, including leap days. It is different from the equal monthly periods used by regular contributions.

Dated flows use Actual/365 and a bounded numerical root search. Multiple, absent or unstable candidates do not establish a unique return; no mathematical completeness outside the displayed bounds is claimed.

Tax and simulation assumptions

The optional tax illustration realizes positive capital gains and dividends annually at one entered tax rate, gives no loss credit and compounds the initial balance only. It excludes contributions and tax deferral. The separate seeded simulation uses an entered arithmetic mean and volatility; no score or market risk is inferred from endpoints.

Constant inflation and tax assumptions are illustrations. Figures use finite-precision arithmetic; this is not a quote, forecast or investment recommendation.
