How to Use This Calculator
Getting an accurate comparison between petrol and electric in 2026 requires more than just a guess. Follow these four steps to see your true potential savings:
Set Your Annual Mileage
The NZ average is roughly 12,000km, but many commuters do 20,000km+. 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 in New Zealand are currently volatile, ranging from $3.15 to over $4.00 in some regions.
- Check your local station: Move the slider to match what you’re seeing at the pump today.
- Test a “Crisis” Scenario: Use the $4.00 button to see how much an EV shields you from future fuel price spikes.
Review Your Power Plan
While the national average is 39.3c per kWh, your specific plan might be much cheaper.
Factor in the “New Reality” (RUCs)
Select your vehicle type to automatically apply the latest March 2026 Road User Charges:
- BEV (Full Electric): Includes the $76.00 per 1,000km rate.
- PHEV (Plug-in Hybrid): Includes the reduced $38.00 per 1,000km rate.
- Admin Fees: Our logic automatically adds the $12.44 NZTA online fee to ensure the numbers are grounded in reality.
