The True Cost of Owning a Car

Short answer

A car's true cost in Singapore is dominated by depreciation — the upfront price spread over the COE's 10 years — plus running costs like road tax, insurance and fuel. In an illustrative Cat A example (OMV S$25,000), ARF, excise, GST, the S$350 fee and a S$132,004 COE push the on-road price near S$192,000 — about S$19,000 a year in depreciation alone.

People focus on petrol prices, but in Singapore the real cost of a car is set long before you reach the pump. It is depreciation — the money you will never get back — plus the running costs. Here is a worked, illustrative example to show how the numbers stack up. The tax rates are from LTA; the OMV, dealer margin and running-cost figures are illustrative and will differ by car.

Step 1: how the on-road price is built

Take a Category A car with an illustrative OMV of S$25,000. The regulated build-up (see OMV, ARF and PARF explained):

On-road price build-up (illustrative Cat A, OMV S$25,000)

The COE is the largest single component. Illustrative OMV; tax rates and COE from LTA.

Component How it’s worked out Amount
OMV Assessed by Customs (illustrative) S$25,000
ARF 100% of first S$20k + 140% of next S$5k S$27,000
Excise duty 20% of OMV S$5,000
GST 9% of (OMV + excise) S$2,700
Registration Fee Flat S$350
COE (Cat A) 21 Oct 2026 premium S$132,004
Regulated subtotal S$192,054

A dealer’s margin sits on top of this. The single biggest line is the COE, not the car itself — which is what makes Singapore car ownership unusual.

Step 2: annual running costs

Running cost Illustrative annual figure
Road tax (1,600cc petrol) ~S$743 (verified formula)
Insurance ~S$1,200–2,500 (varies)
Fuel depends on mileage and pump prices
Parking (season + ERP) varies by location and use
Maintenance & servicing rises as the car ages

Only the road tax here is a fixed, official figure: for a 1,600cc petrol car it works out to about S$743 a year using LTA’s formula. The rest depend on how and where you drive.

Step 3: depreciation — the number that matters

This is the cost most buyers underestimate. At the end of a 10-year COE, the PARF rebate is nil (it only applies if you deregister within 10 years), and the COE itself is fully used up. So over a full 10-year hold, essentially the entire purchase price depreciates.

On the S$192,054 regulated price, that is roughly S$19,200 a year in depreciation alone — before a single dollar of fuel, insurance or parking. Add running costs and the real monthly cost of the car becomes clear.

If you sell or scrap earlier

Depreciation per year is usually lower if you sell before 10 years, because you recover value: a rebate for the unused COE and, if within 10 years, a PARF rebate (part of the ARF paid). That is why many owners track depreciation per year rather than the sticker price when comparing cars — see COE renewal and PQP explained for the end-of-life choices.

This worked example is illustrative; OMV, dealer margin and running costs vary by car and over time. Tax rates and the COE premium are from LTA as of the dates stated. Not financial advice.
