FAQ
How much does a car cost to run per month?
On average, 200–350 € per month depending on car class. A small economy car from ~150 €/month; an SUV or premium car 400–550 €/month.
Is diesel cheaper than petrol?
On fuel alone — yes, about 30% less per litre. But diesel servicing is typically more expensive, and if you cover fewer than 15,000 km/year the saving is minimal. Diesel also faces increasing restrictions in city centres across Europe.
How much does an electric car cost to run?
Approximately 158 €/month for a mid-size EV. Electricity costs roughly 3× less than petrol; servicing costs are minimal (no oil changes, fewer brake jobs due to regenerative braking). The purchase price is higher, but running savings accumulate quickly.
Conclusions
Owning a car costs more than just fuel. For a mid-size car, realistic total annual running costs are 2,500–4,000 € (200–350 €/month).
Key rules:
- Smaller car = lower running costs
- EV/hybrid = cheapest to run
- Regular maintenance = fewer expensive repairs
- Compare insurance prices every year at renewal
When budgeting, always add a 10–20% buffer for unexpected costs.
