Purchase price alone does not show whether a used car is good value. A more useful comparison is the amount of value the car may lose during the period you plan to own it. Understanding used-car depreciation in Singapore helps buyers compare vehicles with different COE balances, ages and end-of-ownership values.
A simple depreciation formula
A practical planning formula is:
Estimated annual depreciation = (purchase price – expected value when you sell or deregister) / intended years of ownership
The expected end value may include an estimated resale value, eligible PARF/COE rebate or body value, depending on when and how you intend to exit. It should be treated as an estimate until verified.
Example for comparison
Assume a buyer pays S$30,000 for a car and expects it to be worth S$10,000 after four years. The estimated depreciation is S$5,000 per year: (S$30,000 – S$10,000) / 4.
A second car may cost less today but have little remaining value at the end. Its annual depreciation can therefore be similar or even higher. Always compare the same ownership period.
Why COE changes the calculation
Singapore vehicles can have very different COE expiry dates. A car with more remaining COE usually provides a longer legal-use period before renewal or deregistration. For a renewed-COE vehicle, buyers should also confirm whether it has a five-year or ten-year renewal and what happens at the end of that term.
Do not add an assumed future COE rebate without checking the official vehicle record and the intended deregistration date.
Costs depreciation does not include
- Loan interest and financing charges
- Road tax and age surcharge
- Motor insurance
- Inspection and servicing
- Parking, ERP and fuel
- Repairs, tyres, battery and wear items
Depreciation is only one part of ownership cost. A reliable lower-depreciation vehicle may still cost more each month if it has high road tax, insurance or maintenance requirements.
Use three planning scenarios
Create conservative, expected and optimistic end-value estimates. The conservative figure is particularly useful for older or uncommon models because resale demand and repair condition can change. Stress-test the calculation with a shorter ownership period as well.
Information to request before buying
- Original registration and COE expiry dates
- Current COE category and renewal history
- Official PARF/COE rebate enquiry, where relevant
- Vehicle condition and expected rectification work
- Written quotation showing included and excluded charges
Use the registration record and current market evidence rather than model year alone. Final rebate eligibility and statutory values should be confirmed through LTA OneMotoring.
