Tool 01
This free tool uses your own electricity prices, fuel price, charging mix, and yearly distance. The estimate focuses on energy spend only so it stays fast, simple, and easy to compare.
Treat every money field as your own currency. This tool compares energy spend only.
Polestar 3 stays cheaper to run on energy than a 7.4 L/100 km ICE under these inputs.
Charging cost range: Home only $527/yr ↔ Public only $1,383/yr
I’d save $874 per year with Polestar 3 Long Range Dual Motor under these inputs.

Best for buyers who want a premium electric SUV with real long-distance charging capability and a more design-forward identity than the conventional German default.
How to read this tool
The calculator uses your electricity price, charging mix, yearly distance, and vehicle selection to produce an annual energy-cost figure. It compares that against the fuel cost of a comparable petrol or diesel car using the consumption and fuel price you enter. The gap between those two numbers is the annual energy saving.
This is an energy-spend comparison only. It does not include purchase price, finance, insurance, registration, tyres, depreciation, or servicing. Maintenance savings appear as a separate line to keep them visible but distinct from the energy figure. Use this as a directional check, then validate the full ownership case with the charging-fit and shortlist tools.
Questions buyers ask
The estimate is directionally accurate when your inputs are realistic. A 12% efficiency overhead is applied above the theoretical kWh-per-km figure to account for charging losses and real-world variance. Treat the result as a planning range — it is calibrated to be conservative rather than optimistic.
The calculator covers energy spend only: electricity for the EV and fuel for the comparison ICE vehicle. It does not model purchase price, loan interest, insurance, registration, tyres, or major service costs. Estimated maintenance savings are shown separately as a rough annual proxy based on typical EV versus ICE servicing differences.
Enter the price you actually pay per kWh on your home tariff for the home rate, and the typical price at chargers you use regularly for the public rate. If you are on a time-of-use tariff and charge overnight, use your off-peak rate as the home figure. Blending those two rates by your home-share percentage is how the tool produces its blended electricity cost.
The home share percentage directly sets how much of your annual energy demand is priced at the cheaper home rate versus the more expensive public rate. A high home share (70% or above) typically produces a larger saving over petrol. A low home share (below 40%) can significantly narrow or even eliminate the cost advantage, especially where public charging is expensive.
Yes. Enter your diesel price as the fuel price and the diesel consumption figure in litres per 100 km as the ICE consumption field. The comparison logic is identical. Use your realistic consumption for city or mixed driving rather than a manufacturer claimed figure.
