Costs matter. Whether you’re buying a car or selecting an investment strategy, the costs you expect to pay are likely to be
an important factor in making any major financial decision.
People rely on a lot of different information about costs to help inform these decisions. When you buy a car, for example, the sticker price indicates approximately how much you can expect to pay for the car itself. But the costs of car ownership do not end there. Taxes, insurance, fuel, routine maintenance, and unexpected repairs are also important considerations in the overall cost of a car. Some of these costs are easily observed, while others are more difficult to assess. Similarly, when investing in mutual funds, different variables need to be considered to evaluate how cost‐effective a strategy may be for a particular investor.
