Does the calculator really open with these two cars selected?

Yes. Use Open prefilled calculator — the home page applies this EV, the Corolla Hybrid, and the default region from the link. You can change anything before you run TCO, or use View 5-year result now to skip straight to results at 12,000 km/year.

Does CarCostIQ pick an automatic winner between Atto 3 and Corolla?

No. The live calculator depends on your km, region, overrides, and charging mix. This page explains typical trade-offs; run the tool for your scenario.

Why the Corolla Hybrid?

Toyota Australia now sells the Corolla as a hybrid only — the petrol-only grades have been discontinued — so the Corolla Hybrid is what you can actually buy new and the fair efficient-ICE baseline against a small EV. You can select other Toyota or competitor models in the calculator if they appear in the vehicle list.

Can I share my numbers with someone else?

Yes. After you calculate, use Share link on the result page — the URL encodes your inputs.

Is stamp duty included?

Not by default. Add optional on-road extras in advanced fields if you want to approximate drive-away costs.

Is this financial advice?

No. CarCostIQ is an educational comparison tool. Confirm taxes, incentives, and finance with qualified professionals.

How often do prices update?

Vehicle MSRP and defaults follow my regular data refresh schedule; check the data panel on the home or result page for the latest refresh note.

BYD Atto 3 vs Toyota Corolla Hybrid — 5-Year Cost Comparison (Australia)

This comparison pairs a popular small SUV-style EV (BYD Atto 3) with Australia's best-selling small car, the Toyota Corolla — now sold here exclusively as a hybrid (Corolla Hybrid). Both sit in the mass-market band, but they differ in purchase price, energy cost per kilometre, and how resale is modelled over five years. The Corolla Hybrid is the efficient petrol-electric benchmark a small-EV buyer most realistically cross-shops, since the old petrol-only Corolla is no longer sold new. When you open the prefilled calculator, a green confirmation shows both names and the default state so you can see the hand-off worked before you change km or tariffs.

Best for buyers who want a fair cash-cost view before visiting dealers — especially if you commute daily, share one car in the household, or are weighing your first EV against a familiar Toyota hybrid nameplate.

Quick trade-off summary

No fixed winner here — outcomes depend on your km, tariffs, and any assumptions you change. Typical tensions:

The Corolla Hybrid usually starts with a lower MSRP in my reference data and already sips fuel; the EV side can still claw back cost through cheaper per-km electricity if you drive enough km and charge at reasonable effective rates.
Running costs (insurance, maintenance in the model) are flat annual estimates — your real quotes can shift the gap either way.
Resale assumptions are uncertain for any vehicle; EV used markets are still evolving, so treat residual as a sensitivity lever, not a guarantee.

Who this comparison is for

Daily commuter: ~12–16k km/year, mostly weekdays; energy and parking patterns matter.
Family buyer: One primary car; cares about total 5-year cash and predictable servicing lines in the model.
Urban driver: Lower annual km can reduce the EV energy advantage; check whether purchase-price gap dominates.
High-km driver: 20k+ km/year magnifies fuel vs electricity; revisit charging mix if you rely on DC fast charging.
Mixed city / highway: Efficiency figures are averages; your real L/100 km or kWh/100 km may differ.

Key assumptions behind the comparison

Region scope: all 8 Australian states and territories in CarCostIQ — switch region in the calculator to match yours.
Horizon: five-year TCO unless you change the period in product settings tied to methodology.
Annual km: defaults are a starting point; small changes compound across energy lines.
Charging mix: optional home vs public blend adjusts effective c/kWh; heavy public use usually raises EV energy cost in the model.
Insurance & maintenance: flat annual inputs for both sides so the comparison stays apples-to-apples until you override.
Residual: fraction of MSRP credited at period end — simplified market view.

When the EV is more likely to come out ahead

You drive enough annual km that lower per-km electricity cost offsets a higher purchase price in the scenario you enter.
Your effective electricity rate (after charging mix) stays favourable versus pump prices you expect.
You keep insurance/maintenance assumptions realistic and the EV residual you choose is not overly pessimistic.

When the petrol / hybrid side may still win on cash cost

Annual distance is low, so the EV's per-km energy savings never catch the upfront price difference you see in the tool — and the hybrid already keeps fuel use low.
Petrol stays relatively cheap in your overrides, or your EV side assumes a lot of high-cost public charging.
The Corolla Hybrid is usually cheaper to purchase upfront than the EV on MSRP, and residuals favour the hybrid side in your inputs.

Cost drivers to watch

Annual km — scales energy linearly in the model.
Electricity tariff and charging mix — move effective c/kWh for the EV.
Petrol price (c/L) — directly scales fuel cost.
Residual fractions — change the end-of-period credit.
Optional on-road extras — shift purchase baseline for either vehicle.
