The Car Cost Calculator
A Japanese simulator compares the real ownership cost and estimated cumulative CO2 emissions of multiple cars.
Field notes
The model treats ownership as a time series rather than a purchase event, combining acquisition, financing, taxes, energy, insurance, parking, maintenance, repairs, and expected resale. It also separates vehicle manufacturing, driving, and battery-related emissions, and exposes assumptions such as charging losses and regional incentives for editing. The visible example compares three powertrains—a petrol Yaris, hybrid Prius, and electric Leaf—using links to government, manufacturer, and industry data.
