How this calculator works
Annual operating cost = annual km ÷ km/L × petrol price per litre + annual maintenance + annual insurance. Break-even years = purchase premium ÷ annual operating saving when both are positive.
Read the full methodology for definitions, conversion factors and limitations.
Worked example
A 3,000 purchase premium and a 600 annual operating saving gives a simple 5-year break-even, before resale, financing or the time value of money.
Before you act on the result
Use realistic local prices and your measured consumption where possible. Figures are scenario estimates, not forecasts. Fuel prices, electricity tariffs, driving conditions and ownership expenses can change. The selected currency labels your figures; it does not convert them.
Frequently asked questions
What if the hybrid never breaks even?
If it costs more to buy and has no annual operating saving, there is no future crossover under those assumptions. The tool also handles vehicles that start cheaper but cost more to run.
Is resale included in break-even?
No. Optional resale values are subtracted only at the selected ownership horizon. The operating-cost crossover excludes resale because future yearly resale values are unknown.
