In this lesson
- Compute the total cost of ownership of a car over a holding period
- Compare buying new and used, and explain depreciation
- Compare cash, a loan, a financial lease and an operating lease, and test a 0% offer against a cash discount
- Use the waiting rule and hours-of-work pricing to avoid impulse buys
Andrej needs a car for a new job. A dealer offers a new one for “only €250 a month” and a “0% financing” deal. A neighbour sells a three-year-old car for less. How should he compare them?
Count the whole cost
The is everything a purchase costs over the time you own it. For a car it includes:
- : the value the car loses;
- financing costs (loan interest);
- insurance;
- fuel or electricity;
- maintenance and tyres;
- taxes, registration, parking and tolls.
Depreciation is usually the largest cost of a new car, because a new car typically loses value fastest in its first years.
Cash, loan or lease
- Cash is cheapest if it does not empty your emergency fund.
- A loan means you own the car and pay interest.
- A financial lease is paid off over time, and you normally own the car at the end.
- An operating lease is as renting: kilometre limits, damage charges and early-exit penalties apply, and you own nothing at the end.
A “0% for 48 months” offer is not free. Compare the present value of the payments with the cash price.
Slow down before big wants
Two habits help. A waiting rule for big non-essential purchases: write it down and wait 24 hours (30 days for big ones) before deciding. And hours of work: a €900 TV at €9 an hour net costs 100 hours of your life. These are behavioural tools, not laws.
For older drivers, keeping a paid-off car is often cheaper than replacing it, while safety features and repair frequency matter. At low mileage, car-sharing or taxis can beat ownership.
