If you have ever browsed used-car listings here, you will have noticed something odd to newcomers: every advert leads with a “depreciation” figure, often in bigger type than the price. That is not marketing fluff. Car depreciation in Singapore is the single most important number when you buy, because it tells you what the car actually costs you to own each year. Two cars with very different sticker prices can cost you roughly the same per year, and two cars with similar prices can be worlds apart. Once you learn to read depreciation, the whole market suddenly makes sense.
This guide explains what depreciation means in the local context, how it is generally worked out, and how to keep it as low as possible. For the actual rebate and COE figures behind the maths, always check the current values on One Motoring and with the Land Transport Authority (LTA), because they change constantly.
What Depreciation Actually Means Here
In most countries, depreciation is a vague idea about a car losing value over time. In Singapore it is a specific, calculable number, because a big chunk of what you pay for a car is not the car at all. It is the Certificate of Entitlement (COE), the tax-based Additional Registration Fee, and other duties that are baked into the price.
The key insight is that some of that money comes back to you. When a car is deregistered at the end of its life, or exported or scrapped early, the owner can be entitled to rebates: a PARF rebate (from the Preferential Additional Registration Fee scheme) and any remaining COE rebate for the unused portion of the COE. So the true cost of owning the car is not the full price you paid. It is the price you paid minus the money you get back at the end.
That difference, spread over the years you keep the car, is your depreciation. It is the closest thing to the real cost of putting the car on the road.
How Annual Depreciation Is Generally Calculated
The rough formula that dealers and buyers use is simple in shape:
Annual depreciation = (purchase price minus the rebates you would get at deregistration) divided by the number of years left before the COE expires.
So if you buy a car and there are a certain number of years left on its COE, you take what you paid, subtract the PARF and COE rebate you would eventually receive, and divide by those remaining years. The result is a per-year cost that lets you compare very different cars on the same footing.
A few things to keep in mind:
- The rebate portion depends on the car’s original registration value and its age, and the rules and rates are set by LTA. Do not assume a figure. Use the value shown on the listing or work it out from the current rules on One Motoring.
- Most cars in Singapore are assumed to run to the end of a ten-year COE, so “years left” is usually counted to that point. A car can run beyond ten years if the owner renews the COE, but that changes the sums entirely.
- Depreciation is a projection, not a guarantee. It assumes you keep the car to COE expiry and that rebate rules stay broadly the same.
Why Buyers Compare Depreciation, Not Sticker Price
Sticker price tells you how much cash or loan you need up front. Depreciation tells you how much the car quietly costs you every year you own it. For most buyers, the second number matters far more.
A newer car with a high price but a large future rebate can depreciate slowly. An older, cheaper car near the end of its COE can depreciate faster per year, because there are fewer years left to spread the loss over and the rebate is smaller. The cheap car can genuinely be the more expensive one to own.
This is why local buyers instinctively ask “how much depreciation?” before “how much is it?” It is the honest apples-to-apples measure. Sticker price flatters short-COE cars, while depreciation strips that away and shows the real annual bite.
PARF Cars Versus COE Cars
You will constantly see cars described as “PARF” or “COE” (sometimes “OPC” for older schemes, but PARF and COE are the main two). The distinction matters for depreciation.
- A PARF car is under ten years old and still qualifies for the PARF rebate when deregistered. Because it carries that future rebate, more of your money comes back at the end, which usually means lower, steadier depreciation.
- A COE car has passed the ten-year mark and its owner renewed the COE for another term. It no longer qualifies for the PARF rebate, so at deregistration you generally only get back the unused COE portion, if any. These cars are cheaper to buy but can depreciate differently, and you are running an older vehicle.
Neither is automatically better. A PARF car suits buyers who want predictability and a newer car. A renewed-COE car can suit someone who wants low up-front cost and plans to run it hard for a few years. Just make sure you are comparing the depreciation, not the price.
| Depreciation concept | What it means for you |
|---|---|
| Annual depreciation | The real yearly cost of the car once rebates are counted; your main comparison number |
| PARF rebate | Money returned at deregistration for a car under ten years old; a big reason PARF cars depreciate slowly |
| COE rebate | Refund for the unused months of the COE if you deregister early; part of what you get back |
| Years left on COE | Fewer years left means the loss is spread thinner, usually raising annual depreciation |
| PARF car vs COE (renewed) car | PARF cars keep a future rebate and often depreciate steadily; renewed-COE cars are cheaper up front but lose the PARF rebate |
How COE Swings Affect Depreciation
Because the COE is such a large part of a car’s price, movements in COE premiums ripple straight through to depreciation. When COE prices are high, new and recent cars cost more, which tends to push depreciation up. When COE prices ease, the opposite can happen.
There is a second, subtler effect on the used market. If COE premiums climb after you bought, demand for used cars with COE already paid can rise, which can support resale values and, in some cases, actually reduce your effective depreciation. If premiums fall sharply, used values can soften. This is why depreciation is a projection: the rebate side is rule-based and fairly predictable, but the market side moves with COE, fuel prices, model demand and the wider economy.
Never quote yourself a COE number from memory or from an old article. COE premiums change every bidding exercise. Check the latest results on One Motoring before you rely on any figure.
Minimising Your Depreciation
You cannot escape depreciation, but you can shape it:
- Compare on depreciation, always. Line up your shortlist by annual depreciation, not price, so you are seeing true cost.
- Match the COE runway to your plans. If you want to keep a car five years, a car with roughly that much COE left can make sense; buying lots of COE you will not use is money spread thin.
- Favour models that hold value. Popular, reliable models with strong demand tend to depreciate more gently. Niche or thirsty cars can lose value faster.
- Buy well and keep it well. A fair purchase price, a full service history and good condition all protect your resale value, which protects your depreciation.
- Do the rebate maths yourself. Confirm the PARF and COE rebate for any specific car against the current rules, rather than trusting a round number in an advert.
Get depreciation right and everything else about car ownership becomes easier to judge, because you finally know what the car really costs you.
