Calculation Overview
Calculate how mutual fund fees and investment advisor expenses eat into your long-term portfolio growth.
Mathematical Model & Formula
Future Value = PMT * [((1 + (r-f)/12)^(12t) - 1) / ((r-f)/12)]
Subtracts the annual fee percentage directly from the compound growth rate to calculate real-world compounding drag.
Variables Defined:
- r: Expected market return rate
- f: Annual advisory fee / expense ratio
Worked Example Scenario
Scenario: Investing $50,000 + $500/month at 8% return with 1.5% fees over 20 years.
- Calculates growth at 8% compounding return.
- Calculates secondary growth at 6.5% return (8% - 1.5% fee).
Result: The difference reveals the total dollars lost to fee friction.
