BYD vs Tesla Total Cost of Ownership: 5-Year Cost Comparison

Over five years, a BYD generally costs less to own than a comparable Tesla, driven mostly by a lower purchase price and slightly cheaper insurance. A BYD Atto 3 lands around $52,000 to $58,000 all-in over five years, against roughly $70,000 to $78,000 for a Tesla Model 3. The gap narrows on running costs, where charging is nearly identical and Tesla's scheduled servicing is actually cheaper. Purchase price and depreciation dollars are what decide it, and both favour BYD.

Indicative 5-yr total	About $52,000 to $58,000	About $70,000 to $78,000

What Is Total Cost of Ownership?

Total cost of ownership, or TCO, is the real cost of a car over the time you own it, not just the sticker price. It bundles every expense into one figure.

The main components are purchase price, charging, insurance, servicing, tyres, and depreciation. Depreciation is usually the single largest cost, yet buyers often ignore it because they do not write a cheque for it.

Comparing TCO rather than purchase price is the only fair way to judge which car is truly cheaper to live with.

Purchase Price: BYD vs Tesla by Model

This is the largest single difference, and it favours BYD across the board.

• BYD Atto 3: From about $44,000 before on-road costs
• Tesla Model 3: From about $60,000 driveaway
• BYD Sealion 7: From about $58,700 driveaway
• Tesla Model Y: From about $64,400 driveaway

A BYD typically undercuts its closest Tesla rival by several thousand dollars, and that head start flows through the entire ownership period.

Government Incentives and Tax Benefits

Both brands benefit equally from Australia's main EV incentive, the Fringe Benefits Tax exemption, which applies to eligible EVs bought through a novated lease.

• FBT exemption: Applies to both brands for eligible models under the luxury car tax threshold of $91,387
• The saving: Commonly $5,000 to $15,000 a year in tax through a novated lease, depending on income
• Coming changes: From 1 April 2027 the full exemption applies only to EVs under $75,000, with a 25 percent discount above that; from 1 April 2029 all eligible EVs move to the 25 percent discount

Because most mainstream BYD and Tesla models sit under $75,000, both keep the full benefit through the current phase. This incentive is broadly brand-neutral, so it does not tip the balance either way.

Charging Costs Over 5 Years

Charging is where many buyers expect a big difference, but there is almost none.

Both cars use similar energy, and the cost depends far more on where you charge than on the badge. At typical home off-peak rates, either car costs roughly $3 per 100 km.

• Home charging: Around $2,700 over five years at average annual mileage, for both
• Public fast charging: More expensive for both, and Tesla's Supercharger network is well priced
• The verdict: Effectively a tie

Tesla's slightly better efficiency saves only tens of dollars a year. Our full breakdown of what it costs to charge a BYD against a Tesla covers the detail.

Insurance Premiums Comparison

Insurance usually favours BYD, and it can be a meaningful annual saving.

Tesla premiums tend to run higher because of repair costs, parts pricing, and structural castings that can make even moderate damage expensive to fix. BYD's lower purchase price also reduces the sum insured.

• BYD: Roughly $6,000 to $8,000 over five years, depending on driver and postcode
• Tesla: Roughly $7,500 to $10,000 over the same period

Premiums vary enormously by individual circumstances, so always get quotes on the exact models you are considering.

Maintenance and Service Bills

Here Tesla actually wins, which surprises many buyers.

Tesla publishes no scheduled servicing at all, recommending only occasional items. BYD sets a fixed schedule of every 12 months or 20,000 km, verified in its warranty book.

• BYD Atto 3: Around $299 a year, roughly $1,500 over five years
• Tesla Model 3: Around $500 to $1,000 over five years on recommended items alone

The trade-off is that BYD's servicing keeps its longer six-year warranty valid. Our detailed comparison of BYD and Tesla maintenance costs explains exactly what each brand asks for.

Tyre Replacement Costs

Tyres are a major EV consumable for both brands, since electric cars are heavy and torquey.

• BYD Atto 3: Roughly $200 to $280 per tyre, around $1,200 over five years with rotation
• Tesla Model 3: Roughly $250 to $350 per tyre, around $1,400 over five years
• Both: Expect a set to last 40,000 to 60,000 km

The difference is modest and depends heavily on driving style and wheel size.

Depreciation and Resale Value

Depreciation is the biggest cost of all, and it is more nuanced than the headline percentages suggest.

Tesla retains a slightly higher percentage, around 57 to 58 percent after three years against roughly 50 to 55 percent for BYD. But because a Tesla costs more to buy, the actual dollars lost are often larger.

• Tesla: Higher retained percentage, but more dollars lost from a higher base
• BYD: Slightly lower percentage, but fewer dollars lost, and a longer warranty that supports used value

For total cost, dollars are what matter, and here BYD's lower purchase price works twice in its favour. Our full analysis of how BYD and Tesla resale values compare covers the trends.

Full 5-Year TCO Summary

Bringing it together for the two most compared models:

• BYD Atto 3: Lower purchase price, similar charging, cheaper insurance, higher scheduled servicing, similar tyres, fewer depreciation dollars. Indicative total around $52,000 to $58,000
• Tesla Model 3: Higher purchase price, similar charging, pricier insurance, cheaper servicing, similar tyres, more depreciation dollars. Indicative total around $70,000 to $78,000

The purchase price and depreciation columns are decisive, and both favour BYD. The running-cost columns are close to a wash, with servicing the one clear Tesla win.

Which Brand Costs Less to Own?

For most buyers, BYD. Its lower purchase price and smaller dollar depreciation outweigh Tesla's cheaper servicing and marginally better efficiency.

Tesla closes the gap on running costs and can make sense if you value the Supercharger network, the brand, or the resale liquidity of a car that sells quickly secondhand. But on pure five-year cost, an affordable BYD is usually the cheaper car to own.

Common Mistakes

• Comparing sticker prices only: Depreciation dwarfs the purchase-price gap over five years
• Assuming Tesla is cheaper to run: Charging is a tie and insurance usually favours BYD
• Thinking BYD servicing is dearer for no reason: It keeps the longer six-year warranty valid
• Judging depreciation on percentage: Fewer dollars lost matters more than a higher percentage
• Ignoring the FBT changes: The exemption tightens from April 2027, so timing matters for lease buyers
• Forgetting insurance quotes: Premiums vary so much that averages can mislead
