Track Time, Event, Cash Flow, and Multiplier.
Reinvested returns compound — so 10% + 10% becomes 21%, not 20%.
Outflows use brackets like <$100>.
| Time | Event | Cash Flow | Multiplier | Balance |
|---|
START = money out of pocket (outflow). EOY = end of year return applied. BOY = begin of next year when the new balance is reinvested.
Tip: Snowball answers are overall % on the starting $100 path with reinvestment.
