Monthly cost has five parts: depreciation (the value you lose), fuel, maintenance, insurance, and parking. For a B-segment car driving 1,500 km a month, total cost usually runs 8–14 million VND a month.
An EV sharply cuts the fuel part, but parking and maintenance stay about the same. Don't forget the road fee and civil insurance, which are charged yearly.
ViDrive's TCO adds up all of these based on the km and years you enter — see the real number right away.
