The shape at 30,000 km for BEV

Energy catches depreciation and maintenance starts to matter. Structures with a mileage cap begin to punish: excess-kilometre charges on a lease or PCP are priced to deter, and a high-mileage car’s guaranteed value is set pessimistically. Ownership — cash or loan — starts to win on total cost. [1]

Cost-line weights for BEV at 30,000 km a year A bar chart combining the powertrain’s cost-line profile with the mileage band’s, on an ordinal scale, for a battery-electric car driven 30,000 km a year. Depreciation5Energy / fuel3Insurance3Maintenance3Tax & fees2Financing cost2
Powertrain and distance together. A line that is heavy for both BEV and this mileage is the one this driver should decide on. Ordinal combination consistent with the total-cost-of-ownership literature cited on this page.

How well each financing structure fits 30,000 km a year A bar chart grading each financing structure from 1 (poorly suited) to 4 (well suited) for a driver covering 30,000 km a year.

Fit at 30,000 km a year. Structures with a mileage cap — lease, PCP, subscription — fall away as distance rises; outright ownership climbs. This is the comparison the monthly figure hides. Grading: our reading of how each structure’s terms behave with distance, not a formal assessment.

The BEV specifics at this distance

Splits into two lines — off-peak home charging and public rapid charging — at very different unit costs. With a driveway, by far the cheapest per kilometre; without one, much of the advantage can go. Winter raises consumption, mostly through cabin heating.

Wins on total cost most clearly for a driver with home charging doing typical-to-high mileage in a market whose tax system rewards low emissions. Loses most clearly for a low-mileage driver without off-street parking.

Energy is now the line that decides it, and it splits sharply: home and workplace charging keep the EV well ahead; a driver dependent on motorway rapid charging can lose most of the advantage. Where you charge on the long days is the largest lever left.

The energy line of any total-cost estimate is the one you control after purchase. Home charging on an off-peak tariff and motorway rapid charging can differ several-fold per kilowatt-hour, so where you charge on long journeys moves the annual number more than the badge does. Drive Charge Eat plans stops around cheaper, reliable chargers that also have somewhere to eat.

Is a battery-electric car worth it at 30,000 km a year?
Wins on total cost most clearly for a driver with home charging doing typical-to-high mileage in a market whose tax system rewards low emissions. Loses most clearly for a low-mileage driver without off-street parking. Energy catches depreciation and maintenance starts to matter.
Should I lease a battery-electric car at 30,000 km a year?
A poor fit at this distance. Warranty mileage limits arrive years earlier than the calendar limit — check which one binds first for the brand you are considering.
