Week 10 Day 7: Fees Are the One Thing You Can Control

In investing, most things are uncertain: will the market go up or down? Will this sector outperform? Will inflation spike? Fees are the one thing that is absolutely certain: they will be charged every year, they will reduce your returns, and they compound against you. Minimizing fees is the one free lunch in investing.

Here is the framework for fee-conscious investing: (1) Core equity holdings: S&P 500 or Total Stock Market index fund at 0.03% (e.g., VTI, FXAIX, SWPPX). (2) International equity: Total International index at 0.05-0.11% (e.g., VXUS, FZILX). (3) Bonds: Total Bond Market index at 0.03-0.05% (e.g., BND, FXNAX). (4) Total all-in annual fees should be under 0.10% for a DIY portfolio. If you use a robo-advisor (Betterment, Wealthfront), add 0.25% for their management fee, bringing total to roughly 0.30%. If you use a human advisor, add 0.5-1.5%, bringing total to 0.55-1.60%. For reference, every 0.25% in annual fees reduces a 30-year portfolio value by approximately 6-7%. A 1.5% all-in fee (common with advisors using active funds) costs roughly 30-35% of terminal wealth versus the DIY index approach. Know your number. Decide if the service is worth the cost.

The concept of 'fee drag' and its compounding impact has led to what Burton Malkiel calls 'the relentless rules of humble arithmetic.' In a zero-sum game (which investing is before costs), costs determine the distribution of winners and losers. Charles Ellis extended this argument in 'The Loser's Game,' comparing investing to amateur tennis: the winner is not the player who hits the most winners but the one who makes the fewest unforced errors. Excess fees are the largest unforced error in personal finance. The total societal cost is staggering: Jack Bogle estimated that the U.S. fund industry charges approximately $600 billion annually in fees across all products. If average fees dropped from the current ~0.40% (asset-weighted) to 0.10%, American investors would collectively retain an additional $200+ billion per year in retirement savings. This is why the shift from active to passive management -- now representing over 50% of U.S. equity fund assets as of 2024 -- is arguably the most important trend in personal finance of the past 50 years.
