Period fee is the amount deducted during that row; total drag also includes the growth lost on earlier fees.
Calculation method
The calculator runs two portfolios side by side every month: one without fees and one with the selected annual fee.
Monthly fee = opening balance × annual fee ÷ 12Contributions are added at the end of each month. Total fee drag equals direct fees deducted plus the compounding growth those fees would have earned.
Your scenario
$100,000 + $5,000 / Monthly · 8.00% · 1.00% · 25 yrs → $4,622,900; Lost to fees $866,249.
