- Depreciation is usually the single biggest cost of owning a new vehicle. Larger than fuel, insurance or servicing.
- The curve is steepest early and flattens later, which is why buying lightly used shifts the worst of it to someone else.
- Configuration desirability, mileage, condition, records and title history influence resale more than diligent maintenance alone.
- It is a cost you only see once, at trade-in or sale, which is why it is so easily left out of a budget.
- For any specific vehicle, real transaction history for the same year, configuration, mileage and region is the only meaningful evidence.
Fuel and insurance are visible monthly. Depreciation is invisible until the day you sell, which is why buyers who carefully compare fuel economy often ignore a far larger number.
Depreciation is simply the difference between what you paid and what the vehicle is worth when you dispose of it. Nothing about it is mysterious, but almost everything about it is specific. To the model, the configuration, the mileage, the condition and the market at that moment.
The shape of the curve
Value does not decline in a straight line. Loss is proportionally steepest early and then flattens, which has direct consequences for when to buy and how long to keep.
The early drop
A new vehicle becomes a used vehicle the moment it is registered, and the market prices it accordingly. The first period of ownership carries the largest proportional loss.
This is the entire argument for buying lightly used: a vehicle a year or two old has had its steepest decline absorbed by the first owner while retaining most of its service life and often some factory warranty.
The long flat middle
After the early drop, annual percentage loss typically moderates. A vehicle kept through this period spreads a smaller loss over more years, which is why long ownership reduces depreciation cost per year.
The tail
Eventually value is governed less by age than by condition, mechanical health and remaining service life. At that stage a well-documented, sound example can be worth meaningfully more than a neglected one of the same age.
What actually moves resale value
Some drivers are inside the owner's control and some are not. Both are worth knowing before purchase, not after.
Configuration is decided once
Drivetrain, colour, powertrain and equipment are chosen at purchase and cannot be changed later. Configurations with broad appeal in your region generally sell faster and closer to asking price than unusual ones.
Records are cheap and they compound
Documented, on-schedule service is one of the few levers that costs almost nothing and reliably supports value. Keep receipts that name the work and the mileage.
Title history is permanent
A salvage, flood or rebuilt brand follows the vehicle for life and materially reduces value, insurability and financing options. This is a purchase-time decision, not a maintenance one.
Modifications rarely return their cost
Personalisation narrows the buyer pool. Some modifications also raise questions about how the vehicle was used. Keep original parts if you modify, so the vehicle can be returned to standard.
| Driver | Effect | Owner control |
|---|---|---|
| Configuration desirability | Large: broadly wanted drivetrains and colours resell more easily | At purchase only |
| Mileage | Large and continuous | Partial |
| Condition and cosmetics | Moderate to large | High |
| Documented service history | Moderate | High |
| Title brands (salvage, flood, rebuilt) | Very large and permanent | At purchase only |
| Accident history | Moderate to large | Partial |
| Segment and market shifts | Large, and outside anyone's control | None |
| Modifications | Usually negative for resale | High |
What counts as evidence for a specific vehicle
Published depreciation percentages describe markets and averages. They do not price the vehicle you are buying or selling.
The closest thing to evidence is what comparable vehicles actually transacted for. Same model year, same configuration, similar mileage and condition, in your region, recently.
- Compare like configurations, not like nameplates. Drivetrain and trim change value materially.
- Use recent transactions, not asking prices, which reflect hope more than market.
- Keep the comparison regional; demand for a given configuration varies by climate and geography.
- Adjust for mileage and condition explicitly instead of assuming they cancel out.
- Treat any title brand as a separate, large adjustment.
A published retention percentage is useful for choosing between segments. It is not evidence about what one specific car is worth.
Putting it in the budget
The way to make depreciation visible is to include it in total cost of ownership alongside the costs you already track.
Estimate the vehicle's likely value at the point you expect to sell, subtract it from what you paid, and divide across the years you intend to keep it. That per-year figure sits alongside fuel, insurance, servicing and tires, and for many new vehicles it is the largest line.
- Estimate a realistic resale value for your configuration at your expected sale point.
- Subtract it from the out-the-door purchase price to get total depreciation.
- Divide by the years you plan to keep the vehicle for an annual figure.
- Add energy, insurance, registration, scheduled service, tires and expected repairs.
- Compare shortlisted vehicles on that total, not on purchase price or fuel economy alone.
Buying and holding to reduce the loss
The levers are mostly pulled at purchase, and the rest is documentation.
- If resale matters, choose configurations with broad regional appeal, not unusual ones.
- Consider a lightly used example to let the first owner absorb the steepest part of the curve.
- Plan the ownership period deliberately: longer ownership spreads a smaller annual loss.
- Keep mileage, condition and documented service in good order throughout.
- Avoid branded titles unless the discount genuinely compensates for permanently reduced value and insurability.
- Compare shortlisted vehicles on total ownership cost, with depreciation included as a line item.
Almost every durable resale advantage is decided on the day of purchase. Maintenance protects value; configuration determines how much value there is to protect.
Common questions
How much do new cars depreciate?
It varies widely by segment, configuration and market conditions, but the loss is proportionally steepest in the first period of ownership and moderates afterwards. For a specific vehicle, recent transactions for the same year, configuration and mileage are the only reliable evidence.
Is buying a used car better for depreciation?
Generally yes. A lightly used vehicle has had its steepest decline absorbed by the first owner while retaining most of its service life and sometimes remaining factory warranty.
Does regular maintenance reduce depreciation?
Documented maintenance supports value and helps a vehicle sell, but it does not outweigh configuration desirability, mileage, condition or title history. Keep receipts that name the work and the mileage.
Do modifications hurt resale value?
Usually. Personalisation narrows the buyer pool and can raise questions about how the vehicle was used. If you modify, keep the original parts so the vehicle can be returned to standard before sale.
How much does a salvage title reduce value?
Substantially and permanently. A brand follows the vehicle for life and also affects insurability and financing. It is a purchase-time consideration instead of something that can be improved later.
Which loses value faster, an EV or a gasoline car?
It depends on segment, model, battery health, incentives and the state of the market at the time, not on propulsion type alone. For an EV specifically, remaining battery warranty and measured state of health are additional value drivers.
How do I include depreciation in my budget?
Estimate a realistic resale value at your expected sale point, subtract it from the out-the-door price, and divide by the years you plan to keep the vehicle. Add that annual figure to energy, insurance, servicing and tires.
