How this model works

Annual grid energy = distance ÷ 100 × battery energy ÷ charging efficiency. Blended electricity rate = home share × home rate + public share × public rate. Annual petrol = distance ÷ 100 × litres per 100 km × price per litre.

Period ownership cost = purchase price − resale value + years × (annual energy or fuel + annual other costs). The EV scenario also adds the one-off charger cost.

Include insurance, servicing, registration and other recurring expenses in the annual non-energy inputs. Finance interest, tax, incentives, inflation and discounting are excluded unless you incorporate their effects into your assumptions. Currency selection changes the label only; it does not convert amounts. Resale value is an assumption, not a forecast.
