Ask someone what their pension or investment fund charges and most will shrug: "about one percent, I think." One percent sounds like a rounding error — the kind of number too small to bother with. It is, in fact, one of the largest single decisions you will ever make about your money. Fees are quiet, automatic, and utterly relentless, and they compound against you exactly the way returns compound for you.
The maths nobody shows you
Take a simple, illustrative example. Suppose you invest a lump sum and it grows at 6% a year for 30 years before any charges. Now run it twice: once paying a 0.2% fee (a cheap global tracker) and once paying 1.2% (a typical actively-managed fund once all costs are counted).
The difference in annual return is just one percentage point. But over 30 years, the low-cost pot ends up dramatically larger — the high-fee version can surrender roughly a quarter to a third of its final value to charges. On a pot meant to fund your retirement, that is not a rounding error. That is years of your life.
"You would never accept losing a third of your pension to a bad market. Losing it to fees feels different only because it happens silently."
Why the damage is so large
Because a fee isn't a one-off. Every year, the charge is taken not just on your original money but on all the growth it had earned — and, crucially, on the growth that money would have gone on to earn. You don't just lose the fee; you lose everything that fee would have compounded into. Small percentage, long time, enormous effect.
The fees to hunt down
- Fund charge (OCF). The headline cost of the fund itself. Trackers are often 0.1–0.25%; active funds frequently 0.75%+.
- Platform fee. What your ISA or SIPP provider charges to hold the investments — a percentage or, better for larger pots, a flat fee.
- Adviser or "advice" fees. Sometimes worth it, but check what you're paying and whether it recurs every year.

Log in and find the actual percentage you're paying — fund charge and platform fee combined. If it's north of 1%, ask what you're getting for it. Moving from an expensive active fund to a cheap global tracker, and from a percentage-based platform to a flat-fee one for a larger pot, is often the single highest-value afternoon of admin in your financial life.
