What the numbers say
The BYD Atto 3 costs about $61,253 to own over 5 years in New Zealand — $1,021/month, $0.88/km at 14,000 km/yr — and depreciation is the biggest line: $30,734, 50% of the total (as of July 9, 2026).
- The Toyota Corolla Cross Hybrid wins decisively here — $14,196 cheaper over 5 years; at typical assumptions this isn't a close call.
- No realistic annual distance flips this verdict — the Toyota Corolla Cross Hybrid stays the cheaper car at every distance we model.
- On cost per month the BYD Atto 3 ranks #7 of 12 compact SUV models we track in NZ.
- Where the BYD Atto 3's $61,253 actually goes: depreciation $30,734 (50%), financing interest $9,402 (15%), insurance $7,000 (11%), registration & fees $6,245 (10%), charging $5,625 (9%), maintenance $2,247 (4%).
- Per km, that is $0.44 of depreciation and $0.08 of charging, with $0.36 for everything else — $0.88/km all-in.

What we assume for maintenance
Assumed $449/yr for an EV at 14,000 km/yr — about $2,247 of the 5-year total above. On this market's assumptions an EV runs about $451/yr less in maintenance than a petrol car ($449 vs $900). See the methodology for sources; adjustable in the calculator.
Cost to charge the BYD Atto 3 at home
The BYD Atto 3 runs about $6.18 per 100 km at home — versus about $20.79 for a typical 7 L/100km petrol car. Home charging only (the ~12% AC charging loss is included); public DC fast-charging is billed per session by each network — often 2–3× the home rate — and isn't in these figures.
- Per 100 km at home
- $6.1816 kWh/100km + 12% charging loss × $0.34/kWh
- A typical 7 L/100km petrol car
