Total cost of ownership (TCO) is everything an asset costs to buy, run, and eventually give up, minus what it returns at resale — not just the sticker price. It bundles purchase price, running costs (maintenance, insurance, fuel or energy), the opportunity cost of capital tied up, and depreciation into a single comparable figure over a defined ownership period.

Why it matters

TCO turns a purchase decision into a comparison of totals instead of a comparison of sticker prices. A cheaper item with high running costs or fast depreciation can cost more over its life than a pricier item that holds value and runs cheap — the purchase price alone hides that. The framework combines three separate ideas — running costs, depreciation, and opportunity cost — into one number, which is why it underlies bigger comparisons like weighing whether to rent or buy housing, or choosing between a car and public transit for a commute.

The method

1. Set the ownership period. Decide how many years (or units of use) you plan to hold the asset — the calculation only makes sense for a defined period.
2. Add the purchase price, net of any immediate rebate or trade-in credit.
3. Add running costs over the whole period — maintenance, insurance, fuel or energy, required fees — summed across every year, not just one.
4. Add the opportunity cost of the capital tied up — what that money would otherwise have earned, since it sits in the asset instead of savings or investments for the ownership period.
5. Subtract the expected resale or residual value at the end of the period — the value depreciation has not consumed.
6. Sum the result to get total cost of ownership. Dividing by the ownership period (or by units of use) gives a comparable rate for lining up against a different option.

Worked example

Buying a car, five-year ownership. Purchase price €18,000. Running costs (insurance, maintenance, fuel) average €2,800 per year. Opportunity cost is calculated on the average capital tied up over the period — roughly the midpoint between purchase price and resale value, €12,500 — at an illustrative 4% annual return. Expected resale value after five years: €7,000.

Component	Amount
Purchase price	€18,000
Running costs (5 x €2,800)	€14,000
Opportunity cost (€12,500 x 4% x 5 years)	€2,500
Resale value after 5 years	−€7,000
Total cost of ownership	€27,500

€27,500 / 5 years = €5,500 per year — a figure that stays comparable against a different car, a lease, or a public-transit alternative, even though none of them share the same sticker price.

Check yourself

A small business buys a machine for €10,000. Running costs (maintenance, energy, insurance) total €500 per year over a planned 4-year ownership period. Opportunity cost on the capital tied up over that period totals €1,200. Expected resale value after 4 years is €2,000. What is the total cost of ownership, in euros?

Which of the following is NOT one of the inputs total cost of ownership sums or nets out?

Purchase priceRunning costs over the ownership periodBrand reputation or prestigeResale value at the end of the period

Holding the purchase price and ownership period fixed, which of these changes lower total cost of ownership? (Select all that apply.)

A higher expected resale value at the end of the periodLower running costs (maintenance, insurance, energy)A higher opportunity-cost rate on the tied-up capitalA longer ownership period, with everything else unchanged

Item A and Item B cost the same to buy. Item A has lower running costs; Item B holds its resale value better. Which one has the lower total cost of ownership?

Item A, because running costs are the biggest factorItem B, because resale value is the biggest factorCannot tell without doing the full calculationThey have equal total cost of ownership since the purchase price is the same
