What a car really costs per month: the calculation beyond the sticker price

Comparing two vehicles only on their purchase price, or even just their financing payment, ignores a large part of the real bill. A vehicle's full monthly cost adds up at least five line items, and the gap between two models can flip entirely once they're all accounted for.

Financing: the most visible line item, not the only one

Whether it's a lease payment or a classic loan repayment, this item is already well understood by most buyers — which is exactly why it isn't enough on its own to compare two vehicles fairly: a cheaper vehicle to finance can consume far more fuel, or cost more to insure.

Insurance: a gap that can exceed 50% between two comparable models

Power, replacement value, the model's theft rate, and even where you park all significantly affect the insurance premium. Two vehicles at an identical purchase price can show an insurance gap of several hundred euros a year — getting an insurance quote before buying, not after, avoids the bad surprise.

Energy: the most structural gap over the long run

Between a tank of petrol, home electric charging, and fast public charging, the cost-per-kilometer gap can range from 1x to 4x. Over 15,000km a year, that gap weighs far more than the payment difference between two similar models — which is why total cost, not purchase price, is the right frame.

Maintenance and depreciation: the items discovered too late

Maintenance varies significantly by powertrain (an electric car mechanically has fewer wear parts than a petrol one) and by brand. Depreciation is only calculated at resale — but it should be anticipated at purchase: two vehicles at an identical new price can have very different resale values three years later.

This is exactly why every vehicle listed on Compar'Car shows an indicative monthly payment right next to the price — a first benchmark for comparing several vehicles on a basis closer to real cost than the sticker price alone.
