How this is calculated
- Monthly payment uses a reducing-balance EMI on the loan (price − down payment).
- Total cost = vehicle price + total interest paid over the loan.
- Total ownership cost (over the term) = down payment + total loan repayments + insurance × years + charging × months.
- EV monthly outgoing = loan EMI + insurance ÷ 12 + monthly charging cost.
- The EV-vs-petrol comparison looks at running cost only (charging vs fuel) and excludes the loan instalment.
