BYD vs Tesla Resale Value: Which Electric Cars Hold Value Better?

Tesla holds a slight edge on resale value in percentage terms, retaining around 57 to 58 percent after three years against roughly 50 to 55 percent for the BYD Seal, though the popular Atto 3 performs better among affordable EVs. The gap is narrower than it looks, because BYD's lower starting price often means fewer actual dollars lost. Both brands are affected by the same force: Tesla's repeated new-car price cuts, which reset used values across the whole EV market overnight.

Resale Value at a Glance

Measurement BYD Tesla
3-year retained value About 50 to 55% About 57 to 58%
Strongest model Atto 3 Model Y
Main depreciation driver New-brand perception New-car price cuts
Starting price Lower Higher
Dollars lost Often fewer Often more
Vehicle warranty 6 years / 150,000 km 4 years / 80,000 km

How EV Resale Value Is Calculated

Resale value is usually expressed as a percentage: how much of the original price the car is still worth after a set time, most commonly three years.

But percentage is only half the story. What actually leaves your bank account is the dollar figure, and a cheaper car losing a higher percentage can still cost you less than an expensive car losing a lower one.

Both matter, and they can point in different directions. This comparison looks at each.

Tesla Model 3 and Model Y Depreciation

Tesla retains value slightly better on paper, with the Model 3 holding around 57 to 58 percent after three years. The Model Y is among the strongest performers in the market.

Yet Tesla's story is complicated by its own pricing. Repeated price cuts in 2023 and 2024 instantly reset used values, and some owners have taken heavy hits.

  • The percentage: Around 57 to 58 percent retained at three years for the Model 3
  • The catch: Because buyers paid a premium, the dollar losses are often large
  • The trigger: Every new-car price cut lowers used values overnight

One widely reported case saw a buyer lose tens of thousands within months of purchase, after further price adjustments. Tesla's depreciation is driven less by the cars and more by pricing strategy.

BYD Seal and Atto 3 Depreciation

BYD sits slightly behind on percentage retention, but the picture varies by model.

  • BYD Seal: A projected three-year retained value of around 50 to 55 percent
  • BYD Atto 3: One of the better-performing affordable EVs, thanks to strong used demand
  • The advantage: A lower purchase price means fewer dollars lost overall

The Atto 3's popularity is its resale protection. High demand in the used market supports its value, and its position as one of Australia's cheapest EVs keeps buyers interested. Because it is the same car globally, our explainer on how the Atto 3 relates to the Yuan Plus shows why global demand underpins it.

Warranty Length Impact on Resale

This is a real BYD advantage that percentages alone miss. A longer warranty transfers to the second owner and makes a used car more attractive.

  • BYD: 6 years or 150,000 km vehicle warranty, so a 3-year-old car still has years of cover
  • Tesla: 4 years or 80,000 km, which may have expired by the time it is resold
  • Both: 8-year battery warranties that reassure used buyers

A used BYD sold at three years old still carries substantial remaining warranty, which supports its resale price. How the two warranties compare in full is covered in our breakdown of what each brand's warranty really covers.

Battery Health and Resale Confidence

Battery anxiety is the single biggest worry for used EV buyers, and it is where BYD has a quiet edge.

BYD's LFP Blade Battery is known for long cycle life and thermal stability, and its warranty guarantees at least 70 percent capacity retention over the term. LFP chemistry also tolerates daily charging to 100 percent, so used examples are less likely to have been stressed by poor charging habits.

Tesla's nickel-based packs are also durable and well-proven, but buyers often pay closer attention to charging history. On both, a documented healthy battery lifts resale confidence considerably.

Brand Perception and Demand

Perception moves the used market as much as data does.

  • Tesla: A globally recognised brand with strong used-market demand, so cars sell quickly
  • BYD: Still a newer name to many Australian buyers, despite becoming a top-selling brand in under three years

Tesla's established reputation means used examples find buyers faster, which supports value. BYD's brand is strengthening rapidly, and as familiarity grows, its resale should follow. The gap is narrowing as the used EV market matures.

Factors That Help EVs Hold Value

Across both brands, the same characteristics protect resale value:

  • Stable new-car pricing: Models whose new prices stay steady hold used value best
  • Modern charging architecture: Buyers avoid platforms they fear will feel dated soon
  • Accessible price segment: Mid-priced EVs have a far broader buyer pool than luxury ones
  • Strong used demand: Popular models simply sell better secondhand

Luxury EVs over $100,000 tend to lose the most, sometimes halving within five years. Affordable, popular models like the Atto 3 fare better.

Market-by-Market Differences

Resale performance is not uniform worldwide. In Australia, EVs still make up under one percent of used sales, so values are more sensitive to shifts in supply and sentiment than in more mature markets.

Australian data shows a one-year-old EV loses around 25 percent of its value on average, against roughly 11.5 percent for petrol cars. That reflects the immaturity of the local used EV market rather than any fault with the cars, and it applies to both brands.

Tips to Maximise Your BYD Resale

  • Keep the logbook stamped: A complete service history protects both warranty and value
  • Document battery health: A recent state-of-health readout reassures buyers
  • Choose a higher trim: Premium variants with bigger batteries hold value better
  • Protect the interior: Mats, seat covers, and screen protectors prevent value-sapping wear
  • Sell at the sweet spot: Often 18 to 24 months, after early issues settle but before heavy depreciation
  • Keep software current: An up-to-date car feels newer to buyers

Common Mistakes

  • Judging only on percentage: A cheaper BYD losing 50 percent can cost fewer dollars than a pricier Tesla losing 42 percent
  • Blaming BYD for Tesla's cuts: Tesla's price reductions drag down all used EV values, including its own
  • Ignoring remaining warranty: A 3-year-old BYD still has years of cover, a real selling point
  • Overlooking battery documentation: Buyers pay more for a proven healthy pack
  • Assuming EVs match petrol resale: Both brands depreciate faster than petrol cars today
  • Holding too long: Waiting past the sweet spot often costs more than it saves
