WORKING EV PLANNER
Your driving.
Your assumptions.
Compare annual energy costs, a simple purchase-premium payback and approximate charging time. All dollar inputs use one currency of your choice; no exchange conversion is performed.
See exactly how it works.
Battery energy = kilometres × consumption ÷ 100. Grid energy = battery energy ÷ charging efficiency. Blended tariff = home tariff × home share + public tariff × remaining share. Annual EV cost = grid energy × blended tariff. Petrol cost = kilometres × L/100 km ÷ 100 × price/litre.
Charging time = usable battery × (target − start) ÷ 100 ÷ (average input power × efficiency). Premium payback = purchase premium ÷ positive annual energy saving.
This is an energy comparison, not a full ownership-cost quote. It excludes finance, depreciation, insurance, servicing, taxes, tyres, installation, charging-session fees and time-of-use variation. Negative differences are shown as extra EV energy cost. Constant charging power and fixed consumption are simplifying assumptions; real conditions vary.
