NZ-friendly range fit + running cost comparison
This calculator helps you quickly test whether an EV fits your normal week and compare likely running costs against your current petrol or diesel car. It is only a few short steps and usually takes 2–4 minutes.
Think of this like telling a mechanic how many town runs and motorway trips you do — it helps size the “tank”. EVs actually love predictable, repeatable weeks like this.
This is like picking engine size and fuel tank in an ICE — except with EVs you care more about battery size and efficiency than cylinders and litres.
Complete the wizard and we will summarise whether this EV setup looks comfortable for your week and how the running costs compare with your current car.

Imagine telling a fuel company how often you fill up and what you drive — this lets us estimate how much you currently burn in fuel each year.
This is the EV version of fuel price and fill‑ups — except most “fills” happen quietly at home while you sleep.

Range maths is a planning estimate (real range varies with speed, hills, wind, tyres, heating, and battery condition). Defaults: Public DC fast charging ~$0.82/kWh · EV RUC $76/1,000km.
