About Investment Fee & Expense Ratio Calculator

The Investment Fee Calculator exposes the hidden cost of management expense ratios and financial advisor AUM fees, calculating total dollar wealth lost to fees over 10 to 40 years.

Formula & Mathematical Calculation

Fee Drag ($) = Portfolio Value (Low-Fee Fund) - Portfolio Value (High-Fee Fund)

Calculation Example

$100,000 Portfolio + $500/mo over 30 Years @ 8% Return: Low-Fee Index Fund (0.05% fee) = $1,273,000. High-Fee Fund (1.50% fee) = $873,000. You lose $400,000 (over 31% of your total wealth!) to fees!
