A COE premium can dominate the headlines, but it does not show what a household will spend over the period it owns a vehicle. Before deciding, account for the full package:
- Purchase price and depreciation: compare the all-in vehicle price and the value it may retain over your ownership period.
- Financing: estimate loan interest and check that repayments fit comfortably within your monthly budget.
- Recurring charges: include road tax, insurance, fuel or charging, servicing, tyres and repairs.
- Parking and road charges: estimate home and workplace parking, ERP and other costs from your actual routes.
- How you use the car: a vehicle used every day for family needs has a different value from one mainly used for occasional weekend trips.
Watch for double-counting. When comparing dealer quotes, confirm whether the stated vehicle price already includes the COE. Do not add the COE premium a second time if it is already included in the quoted price.
3. When can a car be worth paying more for?
The cheapest transport option is not necessarily the best choice for every household. A car may be worth its additional cost if it regularly helps you:
- transport young children or family members who need assistance;
- make several stops across the island in one day;
- travel at unusual hours or to places with inconvenient public transport connections; or
- carry equipment, groceries or other bulky items frequently.
On the other hand, MRT and buses may be sufficient for residents with a convenient commute, while a mix of public transport and Grab can cover occasional late-night trips or family outings without the fixed costs of owning a vehicle.
4. Compare the same journeys, not just the monthly instalment
A common mistake is to compare a car loan instalment with the cost of an MRT trip. Those numbers do not measure the same thing. For a fair comparison, estimate three scenarios for your household:
- Own a car: account for depreciation or ownership cost, financing interest where relevant, insurance, road tax, fuel, parking, ERP and maintenance.
- Public transport: estimate the MRT and bus fares for your regular weekday and weekend journeys.
- MRT plus Grab: add the Grab rides you actually expect to take, such as late-night journeys, trips with children or routes where public transport is less practical.
Compare annual costs as well as monthly cash flow. If you are considering a longer ownership period, test different assumptions rather than relying on a single forecast. A change in parking costs, trip frequency or resale value can affect the result.
Make your transport decision with your own numbers
SGEventsHub's resident transport guides can help you compare the practical trade-offs between MRT, buses, Grab and car ownership. Start with the transport section, then estimate costs using your actual journeys and household needs.

5. Should you wait for the proposed COE changes?
There is a policy question for car buyers to watch, too. On 8 October 2026, LTA opened a public consultation on a preliminary proposal to combine Categories A and B into a single passenger-car category and introduce a fee-and-rebate system linked to the vehicle's value. LTA is also seeking views on how Category E should be adjusted if the categories are merged.
This is a proposal, not a confirmed change to the rules. The consultation runs until 11.59pm on 2 November 2026. LTA expects to share its findings and recommendations in the first half of 2027. Buyers should not assume that waiting will automatically make a particular car cheaper, because both the final policy and future COE premiums remain uncertain.
If your purchase can wait, follow the official consultation and ask dealers for a written breakdown of the quoted price, COE assumptions, financing terms and conditions. If you need a car now, make the decision based on affordability and your real transport needs rather than trying to predict the next bidding result.
Before you commit: five questions to ask
- What is the realistic total monthly and annual cost of owning this car?
- What would my equivalent MRT, bus and Grab use cost?
- How much time or inconvenience would the car save on trips I actually make?
- Would the money be more useful for housing, savings or another household priority?
- Could I still comfortably afford the car if COE premiums stayed elevated?
The bottom line
The 21 October COE exercise kept Category A premiums above S$132,000 and Category B above S$131,000, while other categories moved in different directions. LTA has also warned buyers to be prudent ahead of the weekend Car Expo.
For residents, neither a single bidding result nor speculation about future policy can settle the car-versus-public-transport decision. Compare the full cost of ownership with the cost of the journeys you need to make, weigh convenience against your budget, and choose the option that works for your household over time.
