How to Use This Calculator

Follow these steps to get an accurate comparison based on current 2026 data:

Set Your Annual Mileage

The NZ average is roughly 12,000km. Use the slider to match your actual driving habits. The more you drive, the faster an EV pays for itself.

Match Your Local Pump Prices

Petrol prices vary across NZ. Adjust the slider to match your local station, or use the Auckland ($4.00) button to see the impact of higher costs.

Review Your Power Plan

Pro Tip: If you have an “EV Plan” for cheap overnight charging (e.g., 15-20c), drop the slider to see your savings double.

Factor in the RUCs

Select your vehicle type to apply the March 2026 Road User Charges ($76 for BEVs or $38 for PHEVs) and the online NZTA admin fees.

Frequently Asked Questions

Do I really have to pay RUCs if I buy an EV? +

Yes. As of early 2026, all light Battery Electric Vehicles (BEVs) pay $76.00 per 1,000km, and Plug-in Hybrids (PHEVs) pay $38.00. These are usually bought in “units” via the NZTA website.

What about the admin fee? +

Every time you buy RUC units, there is a transaction fee. We have factored the $12.44 online fee into our “Weekly Savings” calculation, assuming you buy 1,000km at a time to keep your costs transparent.

Is it better to get a Hybrid or a full EV? +

Full EVs (BEVs) offer the highest energy savings, especially with petrol over $3.30. However, if you frequently do long-haul trips where charging is inconvenient, a PHEV ($38 RUC) can be a great middle ground for flexibility.
