Definition
The dependence of an outcome on the order of returns when money is flowing in or out.
How to read it
Two portfolios with identical average returns end far apart if one suffers its losses while withdrawals are largest.
Measured on real funds
2VTI's real monthly returns, run forwards and then backwards. Same returns, same average, same compounded growth, different ending balance: withdrawals turn the order into a variable.
| Order | Ending balance | Assumption |
|---|---|---|
| As it happened | 4,468,429 | $1,000,000 start, $40,000 a year withdrawn |
| Reversed | 7,407,753 | identical returns, opposite order |
303 months of VTI, 2001-07 to 2026-09. Withdrawn monthly, no inflation adjustment. Computed from Yahoo Finance monthly total return, recomputed with every update of the site. How these figures are produced. Run it on your own numbers — free, no account.
What it does not tell you
It only bites in the presence of cash flows. For a portfolio with no contributions or withdrawals the order of returns is irrelevant to the ending value — a point routinely lost in retirement commentary.
