Cost of Owning a Car in Singapore Per Month (2026 Breakdown)

Most people budget for the loan instalment and forget everything else. That instalment is roughly 60% of what you actually pay each month. The remaining 40% — insurance, road tax, parking, fuel, ERP, and maintenance — quietly adds up to several hundred dollars before you have driven a single kilometre.

Here is a realistic breakdown for 2026, covering both new and second-hand cars.

The True Monthly Cost: What Actually Goes Out Each Month

Use this as your baseline. The figures below assume a mass-market Cat A car (1.6L or an EV equivalent), a 7-year loan, and parking in an HDB estate.

New Car (Category A, approx. S$155,000–S$165,000 OTR)

Loan component: Singapore's Monetary Authority (MAS) rules cap the loan-to-value ratio at 70% for cars with OMV ≤ S$20,000, and 60% for cars with OMV above S$20,000. Most current Cat A cars exceed the S$20,000 OMV threshold, so you are looking at a 60% loan maximum.

On a S$160,000 car with 60% financing over 7 years at a flat rate of approximately 2.78% (which works out to around 5.2% effective annual rate), the monthly instalment runs roughly S$1,500–S$1,650.

Running costs on top of the loan:

That is a wide range, but even the lower end represents a significant monthly commitment before the car sits idle on a weekend.

Second-Hand Car Ownership Costs

Buying a used car with remaining COE changes the equation in ways many buyers underestimate.

Lower purchase price, but check the PARF scheme. A 2025-registered car commands a premium over a 2026-registered car because it still carries the old PARF rebate structure — where scrapping at year 9 recovers up to 50% of the Additional Registration Fee (ARF). A 2026-registered car scraps at roughly 5% of ARF. That difference in "paper value" is real money.

Second-hand loan limits are the same. MAS rules apply regardless of whether you are buying new or used. If the car's OMV exceeds S$20,000, you are capped at 60% financing.

Depreciation on a second-hand car:

The standard depreciation formula is: (Purchase Price − Scrap Value) ÷ Remaining Months of COE.

Example: You buy a 2021-registered Toyota Corolla Altis for S$95,000 with 5 years of COE remaining.

• Estimated scrap value (old PARF scheme): S$12,000–S$18,000
• Depreciation: (S$95,000 − S$15,000) ÷ 60 months = ~S$1,333/month

Compare this to a new car at roughly S$1,300–S$1,450/month depreciation (post-Budget 2026, when scrap values dropped to near zero for new cars). The gap has narrowed considerably.

Maintenance costs rise with age. A COE car — one that has already been renewed past its original 10-year mark — will typically need: - Hybrid battery replacement (Toyota/Honda): S$2,000–S$3,000 - Aircon compressor: S$700–S$900 - Timing belt or chain service: S$500–S$800 - Suspension components: S$600–S$1,200

Budget at least S$150–S$250/month into a maintenance reserve for any car older than 8 years. For European brands with DSG gearboxes (Volkswagen, Audi), that buffer should be S$300–S$400/month to cover potential mechatronics repair, which runs S$2,000–S$6,000 depending on whether the unit is repaired or replaced.

Insurance premiums for older cars. Premiums drop with age as the agreed value of the car falls, but this also means any total-loss payout covers less of your outstanding loan. Verify that your loan balance does not exceed the insured value at any point in the loan tenure.

The EV Premium

EVs under the new 2026 incentive structure carry a smaller upfront discount than before — the combined VES Band A rebate of S$22,500 and the EEAI cap of S$7,500 totals S$30,000, down from ~S$40,000 in 2025.

The bigger monthly shock for many buyers is road tax. A BYD Atto 3 (110kW, qualifying for Cat A) pays approximately S$1,502/year in road tax versus S$742/year for a 1.6L Toyota Corolla. That is an extra S$63/month in road tax alone.

The fuel savings partially offset this. At S$0.30/kWh for home charging and 15 kWh/100km consumption, fuel costs roughly S$67/month at 1,500 km/month — versus roughly S$200/month on petrol. You save around S$133/month on energy, but pay S$63/month extra in road tax, for a net saving of approximately S$70/month. That break-even math changes significantly if you cannot charge at home and rely on public chargers at S$0.60–S$0.70/kWh.

What the Loan Instalment Hides

Singapore car loan "flat rates" are quoted at 2.78%, but the effective interest rate (EIR) on a diminishing balance basis is closer to 5.2%–5.4% for a 7-year loan. On a S$96,000 loan (60% of S$160,000), the total interest paid over 7 years is approximately S$18,700 — more than double what a 2.78% headline rate suggests to most borrowers.

This is why the total interest cost is almost never highlighted by dealerships. They show you a monthly instalment figure and the "flat rate." The EIR is rarely mentioned unless you ask.

Putting It Together: Monthly Cost Comparison

The "cheapest" option on a monthly basis is often a renewed COE car bought without a loan — but it carries the highest maintenance risk and zero residual value at the end of the renewal period.

The Singapore COE Navigator

If you are comparing a new buy, a second-hand car, and a COE renewal side-by-side, the decision turns on your specific numbers: your car's current PARF rebate, the PQP, your loan eligibility, and your expected annual mileage.

The Singapore COE Navigator includes a Total Cost of Ownership calculator, a COE renewal vs. new buy comparison worksheet, and a repair cost database for the most common high-mileage cars. It gives you the exact formula to plug in your situation — not a generic estimate.
