Fees Compound Too

What does one percent actually cost?

The idea

An annual percentage fee is charged on the whole balance every year, so its effect grows with the pot.

In the real world

A 1% difference in ongoing charges compounds into a large gap over decades.

Going deeper

An annual percentage fee is charged on the entire balance every year, including on accumulated growth, so it reduces the base that compounds. Its effect therefore grows exactly as the pot does.

Over decades a one percentage point difference in ongoing charges compounds into a substantial share of the final amount. What makes it worth attention is certainty: returns are unknowable in advance, and the fee is published, known and controllable. It is one of very few variables in investing where the better choice can be identified with confidence beforehand.

Where it stops applying

Higher fees are occasionally justified by genuinely different exposure or service, and the cheapest option is not automatically correct. The failure is not comparing at all.

Why it matters

Fees are one of the few variables in investing you can actually control.

Test yourself

Two identical funds charge 0.2% and 1.2%. Someone dismisses the difference as one percent. Over thirty years, why is that not a small number?

Show the answer

The fee is taken every year from the whole balance, including the growth, so it reduces the base that compounds. Over decades the gap grows to a substantial share of the final pot, and unlike returns it is certain and known in advance.
