How Much to Save for Retirement at Every Age
Benchmarks by age, what they assume, and the arithmetic of catching up. Starting at 25 needs $351 a month for a target that costs $1,252 a month if you start at 45.
How Investment Fees Quietly Take a Sixth of Your Pension
A 1% annual charge sounds negligible next to a 7% return. Over thirty years, in our worked example, it costs $96,000 — about a sixth of the final balance — for no additional benefit.
The short version
- Fees compound in exactly the way returns do, in the opposite direction.
- 0.9 percentage points of extra annual charges cost about $96,000 on $180,000 of contributions over 30 years.
- Total cost is the platform fee plus the fund charge plus trading costs — the headline number is rarely the whole number.
- Fees are the only part of your future return you can control with certainty.
Investment charges are quoted as small percentages against returns quoted as larger percentages, and the framing makes them feel trivial. One per cent, against seven. What is one seventh of the growth?
That framing is wrong in a specific and expensive way. The fee is not charged on the growth. It is charged on the whole balance, every year, including the part that came from previous growth — so the money it removes would itself have compounded for the rest of your investing life.
The worked example
Someone invests $500 a month for thirty years. The underlying market returns 7% a year. The only variable is the total annual charge.
| Total annual cost | Net return | Final balance | Lost to fees |
|---|---|---|---|
| 0.0% (impossible, for reference) | 7.0% | $610,000 | — |
| 0.1% (broad index tracker) | 6.9% | $598,000 | $12,000 |
| 0.5% | 6.5% | $553,000 | $57,000 |
| 1.0% (typical active fund) | 6.0% | $502,000 | $108,000 |
| 1.5% (fund plus adviser plus platform) | 5.5% | $457,000 | $153,000 |
Total contributions across all rows: $180,000.
The difference between the 0.1% row and the 1.0% row is $96,000. That is more than half of everything the investor contributed over three decades, removed by a difference of nine tenths of one percentage point a year.
Why the damage is so disproportionate
Each year's fee is taken from the balance, so the fee also removes all the future growth that money would have generated. A $200 charge in year three is not a $200 loss — at 7% for the remaining 27 years, it is roughly $1,250 of final balance. Fees compound. This is the entire explanation.
Finding what you are actually paying
The single quoted number is usually not the total. There are typically three layers, and they stack:
1. Fund charges
Called the ongoing charges figure (OCF), total expense ratio (TER) or expense ratio depending on where you are. Deducted inside the fund, so it never appears as a line on a statement — the fund's published performance is simply lower than it would otherwise be. It is disclosed in the fund's factsheet or key information document.
2. Platform or account fees
Charged by the broker, pension provider or platform holding the investments. Either a percentage of assets (commonly 0.15–0.45%) or a flat annual fee. Which structure is cheaper depends entirely on your balance: percentage fees are better for small pots, flat fees for large ones, and the crossover point is worth calculating once.
3. Transaction and hidden costs
- Trading commissions on each purchase or sale.
- Bid-ask spreads, particularly on smaller ETFs.
- Portfolio turnover costs — the fund's own trading, paid from fund assets and reported separately from the headline charge, if at all.
- Foreign exchange charges on overseas holdings, often 0.5–1.5% per conversion.
- Exit or transfer fees, sometimes per holding.
4. Advice fees
An ongoing adviser charge — commonly around 0.5–1% a year — is often layered on top of everything above. Good advice can be worth it, particularly around complex tax, estate or retirement decisions. What is not worth it is paying an ongoing percentage for an annual review of a portfolio that never changes.
Cutting the total
- Add up what you pay now. Fund OCF + platform fee + adviser fee. Most people have never seen the total in one place, and the total is frequently higher than any individual component suggested.
- Use broad index funds for core holdings. The evidence that most active funds fail to beat their benchmark after costs over long periods is extensive and consistent across markets. You are usually paying more for a lower expected outcome.
- Match the platform to your balance. On $200,000, a 0.35% percentage fee is $700 a year while a flat $100–$200 fee is a fraction of that. On $5,000 the reverse holds.
- Trade less. Every transaction has a cost, and frequent trading also tends to reduce returns independently of the fees.
- Consolidate old pensions — carefully. Legacy workplace pensions often carry high charges, and combining them can cut costs substantially. But some older policies include guaranteed annuity rates or protected benefits worth far more than the fee saving, so check before transferring, and take advice where the sums are large.
Cheapest is not automatically right
Cost is one input, not the only one. A slightly more expensive fund that tracks the index you actually want beats a cheaper one that does not. A platform with a marginally higher fee but reliable service and the accounts you need is a reasonable choice. The point is to know the number and to be getting something for it — not to minimise it at any cost.
Why this is the one thing you control
You cannot control what markets return. You have limited control over how much you can contribute. You have complete control over what you pay in charges, and it is knowable in advance rather than estimated.
An hour spent reading the fee disclosures on your pension and brokerage accounts is, on the numbers above, potentially the highest-paid hour of your financial life.
Common questions
Is a 1% adviser fee ever worth paying?
Sometimes. Complex situations — retirement income sequencing, estate planning, business sale proceeds, cross-border tax — can generate value well above the fee. Behavioural coaching that stops someone selling in a crash has real value too. What rarely justifies an ongoing percentage is a static portfolio and an annual review. Consider whether a fixed-fee or hourly adviser gives you the same advice without a charge that grows with your balance.
My fund returned 9% last year. Do fees still matter?
Yes, because the fee applies every year regardless of performance, including the years when returns are negative. And last year's return tells you very little about next year's — performance is not persistent in the way costs are. Costs are the only variable you know in advance.
Where do I find my pension's charges?
Start with the annual statement, which in many countries must disclose costs in a standard format, then check the key information document for each fund you hold. If it is not clear, ask the provider in writing for the total ongoing cost including fund charges, platform charges and transaction costs. They are generally obliged to tell you.
