BYD Dolphin Price and Running Costs: The Honest Numbers
The BYD Dolphin starts from about $29,990 before on-road costs, making it one of the most affordable EVs on sale. Running it is where it shines: using the manual's consumption figures, home off-peak charging works out around $3.20 to $3.60 per 100 km, roughly $10 a week for typical driving, about a quarter of a petrol hatch's fuel bill. Add modest capped-price servicing and a 6-year warranty, and the numbers stack up honestly.

The Purchase Price
The Dolphin's headline appeal is its entry price. The Essential opens from about $29,990 before on-road costs, with the Premium sitting in the mid-to-high $30,000s for its bigger battery and stronger motor.
Pricing and offers change through the year and vary by state once on-roads are added, so treat these as a guide and confirm current BYD pricing before you buy. For what each variant gives you, our Essential versus Premium comparison breaks down the differences figure by figure.
What It Costs Per 100 km
Here is where the honest maths begins, anchored to the owner's manual. BYD publishes NEDC consumption of 12.6 kWh per 100 km for the Standard Range and 14.2 kWh for the Extended Range.
Those are laboratory baselines, and real-world driving typically sits a little higher, around 15 to 16 kWh per 100 km depending on conditions and driving style. The tables below use the manual's baseline, so allow a margin on top for real-world use.
Cost by Where You Charge
| Measurement | Standard Range | Extended Range |
|---|---|---|
| Home off-peak (about 25c/kWh) | $3.15 per 100 km | $3.55 per 100 km |
| Home standard rate (about 32c/kWh) | $4.03 per 100 km | $4.54 per 100 km |
| Public DC fast charging (about 60c/kWh) | $7.56 per 100 km | $8.52 per 100 km |
| Petrol hatch comparison (7 L/100 km at $1.90/L) | $13.30 per 100 km | |
The pattern is clear: charge at home, ideally off-peak, and the Dolphin costs a quarter of a petrol car to run. Lean on public fast charging and the gap narrows, though it never closes. Electricity and fuel prices vary by state and plan, so run the same sums with your own rates.
Your Cost Per Week
For a typical 300 km week, here is what the energy bill looks like.
- Home off-peak: About $9.45 to $10.65, call it around $10 a week
- Home standard rate: Roughly $12 to $14 a week
- Petrol hatch equivalent: Close to $40 a week
Over a 15,000 km year, off-peak home charging totals roughly $470 to $530, against about $2,000 in petrol for a comparable hatch. That is close to $1,500 a year staying in your pocket on fuel alone, which is the core of the Dolphin's value case.
Charging Setup Costs
One honest upfront consideration: how you charge at home. The Dolphin can trickle-charge from a standard outlet using its portable charger, which costs nothing extra to set up, or charge faster from a dedicated wallbox, which involves an installation cost that pays back in convenience.
Our guide to the Dolphin's charger types and ports explains exactly what plugs in where, so you can plan the setup that suits your driving.
Servicing and Warranty
The ongoing costs beyond energy are refreshingly modest.
- Servicing: BYD uses a published schedule with capped-price servicing, typically costing a few hundred dollars a year, and EVs skip oil changes, spark plugs, and much of the wear petrol cars accumulate
- Vehicle warranty: 6 years or 150,000 km, per the BYD warranty book
- Battery warranty: 8 years or 160,000 km with at least 70 percent health retained
- Brakes last longer: Regenerative braking does much of the slowing, stretching brake life

The Other Costs, Honestly
- Insurance: Varies with your profile and location, so quote before buying
- Registration: Varies by state, with some offering EV discounts
- Tyres: Sensible 16 or 17 inch sizes keep replacement costs reasonable
- Novated leases: As an EV under the luxury car threshold, the Dolphin can qualify for fringe benefits tax exemption on a novated lease, a significant saving for eligible employees, so check your eligibility with a specialist
- Depreciation: Resale values for EVs are still settling as the market matures, so buy for the ownership savings rather than a guaranteed resale figure
So, Is the Dolphin Worth It?
On the numbers, yes, for the right driver. The Dolphin pairs one of the lowest EV entry prices with genuinely tiny running costs: around $10 a week in energy for typical driving, modest servicing, and a 6-year warranty backed by the 8-year Blade battery cover.
The value case is strongest for home-charging commuters, where the roughly $1,500 annual fuel saving accumulates quietly year after year. If you cannot charge at home and would rely on public fast charging, the savings shrink, and it is worth running your own numbers first. That is the honest picture.
Protecting the Investment
A final piece of cost sense: small protections preserve the car's condition and value. Fitted floor mats, a boot liner, and a screen protector cost little against what they protect.
