same mileage 5 year，EV versus fuel car, who saves more？enter mileage、energy consumption and car price，by total cost of ownership(TCO) at a glance。free、no registration required。
TCO = purchase price − residual value + energy cost + insurance and maintenance cost。energy cost = annual mileage × energy consumption ÷ 100 × unit price；depreciation at (purchase price × (1 − residual value rate)) amortized over the project life。EV maintenance is lower、cheaper energy，but the purchase price is usually higher、residual value rate is low，5 the year is the key window where the two break even。
the higher the annual mileage、the more expensive fuel、the cheaper home charging，the more the EV dominates；if annual mileage is very low or mainly public fast charging is used，the fuel car may be more cost-effective。this tool is a general-purpose estimator，excluding purchase tax、license plate、depreciation fluctuation and battery replacement risk，results are for reference only。
