Inputs
Read Time vs Money, then enter balances, contribution dates, horizon, and fee % from your statement. If the curve looks wrong, check compounding frequency and whether contributions are beginning or end of period.
One at a time
After each run, change only one input. The input that moves the ending balance the most is the one to verify or research further.
Deliberate tweak
Raise the annual fee by 0.2% for twenty years; if the goal is missed, fees were a larger lever than small differences in last year’s performance.
