If you are thinking of buying a car in Singapore this year, it’s more important than ever to understand the full cost of car ownership, not just the showroom price. In 2025, owning a vehicle in Singapore remains one of the more significant financial commitments you will make, due to high taxes, premiums and running costs.
At Key Motor, we are committed to helping you make smart, informed decisions. Here’s a breakdown of what you will really pay, and how you can plan your car purchase with confidence.
1. Certificate of Entitlement (COE): The Big Upfront Cost
The COE is the right to own and register a vehicle for 10 years in Singapore. It is often the single largest cost in buying a car. According to recent data, many mid-sized cars now require a COE of around S$90,000 to S$115,000 depending on category.
What this means: even a “modest” car becomes significantly more expensive once COE is included.
Tip from Key Motor: With COE prices dropping now, it’s a great time to consider your purchase, you could save tens of thousands by locking in your car while premiums are lower.
2. Taxes & Fees: ARF, OMV, GST
Beyond the vehicle price and COE, you will incur taxes and fees:
- OMV (Open Market Value) of the vehicle determines tax base.
- ARF (Additional Registration Fee) is tiered: e.g., first S$20k at 100%, next S$30k at 140%, etc.
- Excise duty (~20% of OMV) and GST (currently 9%) further add cost.
3. Recurring Costs: Road Tax, Insurance, Maintenance, Fuel
Owning a car isn’t just about the purchase. On an ongoing basis you will pay:
- Road Tax (based on engine size / EV power)
- Insurance premiums (higher for younger / new drivers)
- Servicing, repairs, tyres, car wash, maintenance
- Fuel (or charging cost for EVs)
- Parking, ERP (Electronic Road Pricing) and other urban‐usage charges
For example, average annual fuel cost for a petrol car in Singapore is estimated at S$2,000–S$4,000.
These add up, often thousands per year.
4. Depreciation & Hidden Value Loss
Depreciation is often the most underestimated cost. Because of the 10-year COE system, vehicle value drops steeply, especially halfway through its COE life.
When you add loss of value + chance of renewing/ending COE, the “true cost of ownership” becomes much higher.
5. 10-Year Ownership Snapshot
Here’s a rough estimate of what it might look like for a mid-range car over 10 years:
- COE + Taxes + Upfront Fees: S$120,000 – 150,000
- Road Tax + Insurance (10 yrs): S$20,000 – 30,000
- Maintenance: S$10,000 – 15,000
- Fuel/Charging: S$30,000 – 40,000
- Parking + ERP: S$25,000 – 35,000
Total Ownership Cost: ~S$200,000 – 250,000 (≈ S$20,000-S$25,000/yr or ~S$1,700-S$2,100/month)
These numbers are approximate, actual cost depends heavily on vehicle type, usage, condition, driving habits.
Use this as a ballpark to decide whether owning a car is the right financial move for you.
6. Smart Ways to Manage & Reduce Cost
- Opt for fuel-efficient models or EVs/Hybrids, lower running and maintenance costs.
- Work with Key Motor to compare total cost of ownership (TCO) across models, not just price.
- Plan resale/deregistration timing carefully (e.g., before major COE expiry years).
- Structure ownership around your actual usage (commute, family needs) so you pick the vehicle size/type that fits rather than “just because”.
