Every car on a Singapore road is a COE car. The Certificate of Entitlement is the licence to keep a vehicle here for 10 years, and on the second-hand market it is the single number that decides whether a used car is a bargain or a trap. When you buy a secondhand COE car, you are really buying two things: the metal, and the months left on its certificate. Get the COE balance right and you pay a fair price. Miss it and you overpay by tens of thousands, or inherit a renewal bill you never planned for. With Cat A premiums sitting near $124,000 in June 2026 and the PARF rebate cut in February 2026, the maths matters more than ever.
A Certificate of Entitlement is a permit, won at a government auction, that lets you register and use one vehicle in Singapore for 10 years. There is no way to own a car here without one, so the cost of the certificate is baked into every price tag. New or used, you are always buying a COE car.
The certificate is tied to the vehicle, not to you. When you buy a secondhand car, the remaining COE comes with it. A car registered in March 2019 has a COE that runs out in March 2029, and whoever owns it in 2029 has to either renew the certificate or scrap the car. That deadline is the most important fact about any used car you look at.
COEs are auctioned in five categories. Cars sit in Category A (smaller, less powerful, including electric cars up to 110kW) or Category B (larger and more powerful). Category C is goods vehicles and buses, Category D is motorcycles, and Category E is an open category that can be used for any vehicle except motorcycles. If you want the full breakdown of who pays what, our COE glossary entry sets out each category.
Two identical cars can be worth wildly different money purely because of how much COE is left. A car with eight years of certificate remaining lets you drive for years before any big decision. A car with two years left is on a countdown to a renewal premium that can run past $100,000.
Dealers quote a headline price, but the number you should care about is the cost per year of usable COE. Take the asking price, subtract the rebates you would get back if you scrapped the car at COE expiry, then divide by the years of certificate left. That gives you the true annual cost of running that specific COE car, and it lets you compare a cheap old car against a pricier newer one on equal terms.
If you deregister a car before its COE runs out, the Land Transport Authority refunds the unused part of the certificate. The COE rebate is worked out as the quota premium paid, multiplied by the unused months left, divided by 120. A car with 36 months of COE left and a $90,000 premium paid would return roughly $27,000 in COE rebate. This is money the next owner effectively inherits, so it belongs in your valuation of any COE car.
On top of that, cars deregistered before they turn 10 may earn a Preferential Additional Registration Fee rebate, which returns part of the Additional Registration Fee paid at first registration. The ARF itself is a tax pegged to the car's Open Market Value, explained in our ARF glossary entry, and the higher the OMV, the more was paid in the first place.
February 2026 changed this picture sharply. For cars registered with COEs from the second bidding exercise in February 2026 onward, the PARF rebate schedule was cut and the cap was halved from $60,000 to $30,000. A buyer of a newer car now gets back far less at scrap time than the same car would have returned under the old rules, which quietly raises the true cost of owning it.
| Vehicle age at deregistration | Old PARF rebate | Revised PARF rebate |
|---|---|---|
| Up to 5 years | 75% | 30% |
| Over 5 to 6 years | 70% | 25% |
| Over 6 to 7 years | 65% | 20% |
| Over 7 to 8 years | 60% | 15% |
| Over 8 to 9 years | 55% | 10% |
| Over 9 to 10 years | 50% | 5% |
| Over 10 years | Nil | Nil |
| Rebate cap | $60,000 | $30,000 |
COE is auctioned twice a month, with bidding opening at noon on the first and third Monday and running for three working days. The closing premium for each category is whatever it takes to fill the quota, so prices move every fortnight with supply and demand.
At the 17 June 2026 exercise, Category A closed at $123,847, Category B at $123,502, Category C at $93,001 and the open Category E at $129,002. These are the premiums baked into any new car bought today, and they set the benchmark for what a used COE car saves you by carrying an older, cheaper certificate. Our COE price guide tracks how the bidding system sets these figures.
Numbers like these are why the second-hand route appeals. A car registered when premiums were lower locked in a cheaper certificate, and you ride out the rest of that cheaper COE instead of paying today's premium.
| Category | Covers | Premium (17 Jun 2026) |
|---|---|---|
| Category A | Smaller cars, EVs up to 110kW | $123,847 |
| Category B | Larger and more powerful cars | $123,502 |
| Category C | Goods vehicles and buses | $93,001 |
| Category E | Open category | $129,002 |
Loan limits are set by the Monetary Authority of Singapore and cannot be negotiated. For a car with an OMV of $20,000 or below you can borrow up to 70%, leaving a 30% downpayment. Above $20,000 OMV, the limit drops to 60%, so you fund 40% yourself. The maximum loan tenure is seven years for any car, new or used.
For older used cars the bank applies an adjusted OMV that falls with the car's age, which can push a vehicle into the 70% bracket and lighten the downpayment. Your total monthly debt across all loans still has to stay within the 55% Total Debt Servicing Ratio, so a car loan competes with any home loan you carry. Run the numbers in our car cost calculator before you commit, and check how the repayment sits against the rest of your budget using the budget calculator.
Used-car loans often quote slightly lower advertised rates than COE renewal loans, but watch the flat-rate versus effective-rate gap and confirm the tenure does not stretch past the car's remaining COE. Borrowing seven years against a car with five years of certificate left is a quick way to owe money on a car you no longer have.
Once a car's COE expires, the owner can renew it by paying the Prevailing Quota Premium, the three-month moving average of COE prices for that category. A 10-year renewal can be repeated; a 5-year renewal is cheaper but final, after which the car must be scrapped. Renewing also forfeits any PARF rebate, since that only pays out on cars deregistered before 10 years.
For a buyer, the choice is really between a slightly older car with a healthy COE balance and an even older car you would have to renew. A worked comparison: a 2016 model renewed at a roughly $95,000 PQP, plus the PARF rebate lost by renewing, can cost more over five years than buying a 2021 example and selling it on later, despite the higher sticker price. The renewal path makes sense mainly when the car is in excellent condition, low mileage, or a model whose replacement would cost far more. Our COE renewal guide walks through the full sums.
Treat every listing as a short maths exercise. Confirm the COE expiry date, estimate the rebates the car would return at that date under the current rules, and reduce the asking price by that future refund to see what you are really paying to use the car. Then divide by the years of COE left to get a clean cost-per-year you can compare across cars.
Layer on the ownership running costs that never stop: insurance, road tax, servicing, parking and a maintenance reserve for any car nearing the high-wear 100,000km to 120,000km band. A pre-purchase inspection at an independent workshop is the cheapest insurance you can buy against a car that looks fine and hides a gearbox bill.
Every car in Singapore needs a Certificate of Entitlement to be on the road, so a COE car simply means any registered car. When you buy a secondhand one, the remaining years on its 10-year COE transfer with the vehicle and set its real value.
The COE rebate equals the quota premium paid multiplied by the unused COE months, divided by 120. A car with 36 months left and a $90,000 premium paid returns about $27,000, which the next owner effectively inherits and should price into the deal.
For cars registered with COEs from the second February 2026 bidding exercise, the PARF rebate schedule was cut and the cap halved from $60,000 to $30,000. Newer cars now return far less at scrap time, which raises the true lifetime cost of owning them.
Yes. You can borrow up to 70% of the price if the car's OMV is $20,000 or below, or 60% above that, over a maximum seven-year tenure. Make sure the loan does not run longer than the car's remaining COE balance.
