How fast do electric cars depreciate?
Three-year depreciation data paints a mixed picture, and the variation in reported figures reflects genuine differences in methodology and dataset.
| Measure | EV 3-year depreciation | Petrol 3-year depreciation |
|---|---|---|
| Broader market sample | ~61% | ~47% |
| Cap HPI / Cox Automotive | 38–42% | 35–40% |
| Year one, typical EV | 25–35% | 20–28% |
All figures vary by model and data source. Figures vary; verify current data before making purchasing decisions.
Used electric car prices fell by approximately 10% year-on-year in 2026, reflecting continued pressure from new-car discounting. However, EVs under 12 months old showed signs of stabilisation, rising from 52% to 56% of their original cost new between January and October 2025, according to analysis from OneEV Group.
Why do EVs depreciate faster?
The ZEV mandate and manufacturer discounting
The UK's Zero Emission Vehicle mandate requires manufacturers to ensure a rising proportion of their annual new car sales are zero-emission. To hit these targets, manufacturers discount new EVs aggressively — particularly towards year-end — to move volume. Every time a new EV is discounted in the showroom, the equivalent used EV on a forecourt nearby loses value. This is the single most significant structural driver of EV depreciation pressure in 2026.
Battery technology obsolescence
Early-generation electric cars — particularly those with smaller, older battery packs — have depreciated sharply as newer models offering 300-plus miles of range have arrived. Buyer concerns about battery replacement costs, which can run from £5,000 to over £20,000 depending on pack size, also suppress appetite for older used EVs.
Uncertainty in the used market
The used EV buyer pool is smaller than for petrol, which means sellers face more price-sensitive buyers and more limited demand. Insurance and repair costs for older EVs are less predictable than for established petrol models, adding a risk premium that buyers factor into their offers.
Battery State of Health — the new valuation factor
In 2026, Battery State of Health has become the dominant pricing factor in used EV transactions. SOH measures the battery's remaining capacity as a percentage of its original specification. A battery at 95% SOH delivers 95% of its original range. A battery at 75% SOH might cause real-world range to fall meaningfully below what the car offered when new.
What this means practically:
- For sellers: Getting a SOH report before listing your EV will help justify your asking price and speed up the sale. Daily charging to 80% rather than 100% is consistently recommended to preserve long-term cell health.
- For buyers: Always request a Battery Health Certificate or SOH report before committing to a purchase. Anything above approximately 85% is generally considered healthy. New Battery Health Certificates are being introduced in 2026 to formalise this process — figures vary; verify current data.
Which electric cars hold their value best?
Brand matters more than almost any other variable. Premium and established brands consistently outperform the market average:
- Tesla and Porsche have significantly stronger residual values than most other EV brands, driven by brand desirability, software update longevity, and robust charging infrastructure
- Hyundai IONIQ 5 and 6, Kia EV6, and BMW iX series show depreciation rates broadly comparable to equivalent petrol cars
- Volkswagen ID range models have faced used price pressure, partly due to frequent model updates making slightly older versions appear dated
- Early-generation Nissan Leaf and Renault Zoe models have depreciated heavily, particularly older versions with smaller battery packs
- Niche or budget-brand EVs from newer market entrants tend to depreciate fastest

Should depreciation affect your decision to buy or lease?
Depreciation only affects you if you own the vehicle and then sell it. Leasing transfers that risk to the leasing company — you hand the car back at the end of the agreement and the residual value is their problem, not yours.
For EV buyers planning to hold for fewer than three years, the current depreciation environment makes leasing a financially sensible alternative. For longer-term ownership — five years or more at higher mileages — buying outright may be better value overall.
Depreciation affects your total cost of ownership. For what electric cars actually cost to run week to week, including charging, servicing, and tax, see our full guide.
Key takeaways
- Electric cars currently depreciate faster than petrol equivalents on average, though the gap is narrowing for newer models and premium brands.
- The ZEV mandate drives aggressive new-car discounting by manufacturers, which directly suppresses used EV prices.
- Battery State of Health (SOH) has overtaken mileage as the primary factor in used EV valuation in 2026.
- Tesla, Porsche, and established Korean and German EV brands show better residual values than budget or niche entrants.
- Leasing removes depreciation risk entirely, which is worth considering if you plan to change cars within three years.
Frequently asked questions
Do electric cars depreciate faster than petrol cars?
On average, yes, though the gap varies significantly by brand and model. Older or budget EVs depreciate fastest. Premium and established brands — including Tesla, Kia, and BMW — now depreciate at rates broadly comparable to petrol equivalents. The ZEV mandate is the main structural pressure on used EV values. Figures vary; verify current data.
How much does an electric car depreciate in 3 years?
Estimates range from 35% to 61% depending on model and data source. Budget EVs and first-generation models sit at the higher end; newer premium models lose 35 to 42% over three years, broadly comparable to equivalent petrol cars. Cap HPI and Cox Automotive data suggests a narrower gap than some broader market measures. Figures vary; verify current data.
What affects electric car resale value?
Battery State of Health is the biggest single factor in 2026, now more influential than mileage or age in many transactions. Brand, model, mileage, age, and whether the car supports rapid DC charging also matter. ZEV mandate discounting on new cars creates broad downward pressure on used values across all brands.
How do I check battery health on a used electric car?
Request a Battery Health Certificate or SOH report before agreeing to purchase. Many EV dealers now provide these as standard. A reading above approximately 85% is generally considered healthy for a car of typical age. Independent third-party services can also produce a report if the seller cannot provide one.
Is it better to lease or buy an electric car because of depreciation?
Leasing removes depreciation risk entirely — you return the car at end of contract and the residual value is the leasing company's concern. Buying gives you ownership of an asset that has depreciated, but builds equity you can extract at resale. For ownership periods under three years, leasing tends to make more financial sense given current EV depreciation rates. For longer ownership at higher mileage, buying outright may be better overall.
