Understanding costs

Fees reduce your money. Small annual differences can add up over many years.

In more detail

Compare ongoing fees, one-off charges and transaction costs separately. The cheapest option is not automatically suitable; services and risks must also be comparable.

Background

Costs reduce the capital that can continue to grow. A model using the same gross return isolates fee impact but does not predict two real products with different characteristics.

An example

1% of €10,000 is €100 in the first year. That missing money cannot earn future returns either.

A common misconception

The lowest fee is always the best choice.

Fees always matter. But a fee comparison is only meaningful when services and risks are similar. The calculator is not a product recommendation.
