Management Fee Calculator

Calculate the annual management fee on a portfolio and its cumulative cost over time.

About Management Fee Calculator

The headline fee is only part of the cost: every unit paid in fees also stops compounding. That is why the total cost over fifteen years is far larger than the simple sum of the annual charges. A 1% fee sounds small against a 7% return, but it takes roughly one seventh of the return every year and compounds against you.

Formula

Management Fee

Annual fee = portfolio value × fee rate; the true cost adds the compounding those fees would have earned

opportunity cost: Fees plus the growth those fees would themselves have generated
