The true cost: cost per use and total cost of ownership

The price tag is only the beginning. What something costs across its whole life is the real number.

The idea

The price tag is only the start of what something costs. Cost per use divides what you paid by how often you use it: a coat worn every day for years may cost less per use than a cheap one worn twice. It is a simple way to compare purchases that look very different on the shelf.

Total cost of ownership adds everything a thing costs over its life: the price, plus running costs, maintenance, insurance, fuel or energy, accessories, subscriptions it requires, and eventual replacement — minus anything you get back when you sell it. A cheap printer with expensive ink, a car with high fuel and repair costs, or a phone that requires a pricey plan can all cost far more than their price suggests.

Why it matters

Comparing true costs instead of prices leads to better purchases, especially for large items where running costs dwarf the price.

A real example

The situation

Aisha is choosing between two washing machines. One is much cheaper; the other costs more but uses less water and electricity and has a longer warranty.

What happened

She estimates the running costs over eight years and finds the dearer machine is cheaper overall. She buys it and saves on every bill after.

The takeaway

Adding up the whole life of the purchase reversed which option was cheaper.

How people actually behave

People focus on the price paid today because it is visible and immediate, while running costs arrive later in small pieces and feel less real.

Common mistakes

• Comparing only price tags for items with significant running costs.
• Forgetting maintenance, insurance and accessories when budgeting for a purchase.
• Buying cheap items that need replacing often, which can cost more over time.

Questions to think about

• Which thing you own has the lowest cost per use? Which has the highest?
• What large purchase are you considering, and what will it cost over its whole life?

Try it: Cost of a lifetime

1. Choose a purchase you are considering.
2. List every cost over its expected life, not just the price.
3. Compare the total with an alternative before deciding.

Words in this lesson

• Cost per use — The price of something divided by the number of times you use it.
• Total cost of ownership — Everything something costs over its life — price, running costs, maintenance, insurance — minus anything you get back when you sell it.
