What a BYD Sealion 7 costs to own over 5 years

250 km a week in NSW, mostly charged at home. Scheduled service every 12 months or 20,000 km, averaging about $309 a visit. Warranty: 6 yrs / 150,000 km.

Cost to own = price (plus about $4,000 on-road costs where the price is before on-roads) + a home wallbox for EVs (about $2,000, one-off) + charging or fuel + scheduled servicing + tyres. It leaves out insurance, registration and resale value, which vary too much by person and car to estimate fairly. Resale value is the biggest unknown, especially for newer brands.

Compare the BYD Sealion 7 with other cars

Before you buy: three things that change the cost

Where you'll charge

Charging at home is roughly half the price of public fast chargers, and overnight off-peak plans can be cheaper again. Without a garage or driveway you'll rely on public chargers, which narrows the saving over petrol. Most owners pay an electrician to fit a wallbox for faster home charging.

How far you really go on a charge

Claimed ranges come from a lab test. Expect noticeably less on the highway at 110 km/h, with the air-con running or when towing. Choose a car whose range comfortably covers your longest regular trip.

The novated lease tax break ends for some cars

Eligible EVs bought through a novated lease are currently exempt from fringe benefits tax. From 1 April 2027 the full exemption only applies to EVs valued at $75,000 or less, so most cars on this site still qualify. Leases already in place keep their current treatment.

How we work it out

Weekly cost is the car's claimed energy use (kWh per 100 km) × your distance × your electricity price. "Per week" figures on this site assume 250 km a week with 90% of charging at home. Petrol comparisons use the fuel use and price you choose. Prices are list prices at October 2026 and change often; check with the dealer.
