Small fees have a long memory
A fee can reduce today’s balance and the money left to grow tomorrow.
Read the whole fee list
Investment charges can include a percentage of assets, fixed account fees, transaction costs, and charges for advice or withdrawal. Look at all relevant layers instead of choosing a product from one advertised percentage. Ask what is charged, when it is taken, and what service it pays for.
Compare the effect over your timeframe
Money removed in fees no longer earns future returns. This is why a small recurring difference can matter over a long period. A fee expressed as a percentage also changes in money terms as the account balance changes.
Compare products with similar risks, services, and access before treating a lower fee as a complete answer. The cheapest product can still be unsuitable, and a higher fee does not guarantee better performance. Projections that simply subtract an annual fee from a gross return are approximations; actual results depend on how and when both are applied. Always distinguish a percentage-point fee from a percentage reduction in a return.
A transparent one-year calculation
Start with 10,000. Assume a 5% gross gain first: 10,500. If a 1% fee is then charged on that balance, the fee is 105 and 10,395 remains. The net gain is 3.95%, not exactly 4%. Other charging conventions produce different results.
Illustrative numbers, in consistent units.One thing to try
Choose a sample product disclosure, without buying. Find its recurring, transaction, and exit charges and identify the charging basis.
A 1% fee is charged after a 5% gain on 10,000. Under that stated convention, what remains?
