Car Loan Singapore Interest Rate: DBS, OCBC, Maybank Compared

The advertised car loan rate in Singapore — typically quoted as a "flat rate" of around 2.78% per annum — sounds reasonable against a S$150,000 car. What dealers and comparison sites rarely volunteer is that the flat rate and the effective interest rate (EIR) are completely different numbers. A flat rate of 2.78% over 7 years translates to an EIR closer to 5.2% to 5.4%. For a S$90,000 loan, the total interest paid is not S$2,502 per year — it is a figure substantially higher once the EIR mechanics are applied.

Here is what you need to know before signing any loan documents.

MAS Rules: LTV Limits and Maximum Tenure

Before comparing lenders, the regulatory framework is fixed. MAS (Monetary Authority of Singapore) caps both the loan-to-value ratio and the maximum loan tenure for car purchases.

Loan-to-value (LTV) limits: - OMV ≤ S$20,000: maximum loan is 70% of the car's purchase price - OMV > S$20,000: maximum loan is 60% of the car's purchase price

Most new cars — including virtually all EVs and most Cat B vehicles — have OMVs above S$20,000. This means 60% LTV is the operative rule for a large share of buyers. On a S$160,000 car, the maximum loan is S$96,000, requiring a minimum S$64,000 cash or trade-in contribution.

Maximum loan tenure: 7 years. Banks will offer shorter tenures and the monthly instalment rises accordingly. There is no regulatory reason to go shorter unless you prefer to clear the loan faster.

DBS Car Loan

DBS offers car financing under their "DBS Car Loan" product, available for new and used vehicles purchased from authorised dealers. Their current indicative flat rate is approximately 2.78% per annum for new cars, with used car financing typically higher (depending on the car's age and the remaining COE term).

DBS processes applications through their branches and the SGCarMart/Motorist dealer ecosystem. Pre-approval before visiting a dealer is available online. Their approval process is generally straightforward for salaried applicants with documented income.

One DBS-specific consideration: for COE renewal financing (not purchase), DBS does offer renewal loans, though at higher rates than purchase loans and subject to tighter conditions.

OCBC Car Loan

OCBC's car financing rates are comparable to DBS — in the 2.78%–2.98% flat rate range for new cars at the time of writing. OCBC is often competitive on used car loans, including "COE cars" (vehicles older than 10 years with renewed COE), where their willingness to extend financing can differ from DBS depending on current credit policies.

OCBC also offers a hire purchase structure where the bank technically owns the car until the loan is fully paid — standard in Singapore. This is functionally similar to any other car loan for the buyer, but it means OCBC holds the vehicle registration documents (log card) until the loan is discharged.

Maybank Car Loan

Maybank is worth considering specifically for buyers with an existing Maybank banking relationship, as loyalty customers sometimes access preferential rates. Maybank's advertised flat rates are in a similar band to DBS and OCBC, though promotional rates are periodically offered on selected makes and models.

Maybank Singapore also tends to be competitive on Islamic financing structures (diminishing musharakah), which some buyers prefer. The functional cost comparison still comes down to calculating the EIR against total repayment.

Flat Rate vs. Effective Interest Rate: The Gap You Must Understand

This is the single most important piece of information in any car loan discussion.

Flat rate is calculated on the original loan principal for every year of the tenure. On a S$90,000 loan at 2.78% over 7 years: interest = S$90,000 × 2.78% × 7 = S$17,514 total interest.

Effective interest rate accounts for the fact that you are repaying principal continuously — so the outstanding balance falls each month, but the interest charged in a flat-rate structure is based on the original amount. This makes the actual cost of money higher than the headline number.

At a 2.78% flat rate over 7 years, the EIR is approximately 5.2%–5.4%. The total repayment remains the same, but the EIR is the number that allows apples-to-apples comparison with other financial products.

The Singapore COE Navigator includes a worked interest rate calculator that converts flat rate to EIR for any loan amount and tenure — so you can see exactly what your car loan is costing you in real terms before committing.

Car Loan Calculator: What to Input

To calculate your monthly instalment accurately: 1. Loan amount: Car price × LTV ratio (60% or 70% depending on OMV) 2. Monthly instalment (flat rate method): (Loan amount + total interest) ÷ total months 3. Total interest: Loan amount × flat rate × tenure in years

For a S$96,000 loan at 2.78% over 84 months (7 years): - Total interest = S$96,000 × 2.78% × 7 = S$18,666 - Total repayment = S$114,666 - Monthly instalment = S$114,666 ÷ 84 = approximately S$1,365

Add to this: monthly road tax (~S$60–$130), insurance (~S$150–$300), parking (~S$110–$190 season parking), and petrol or charging costs (~S$150–$250). The total monthly cost of car ownership in Singapore routinely exceeds S$2,000 for a mass-market vehicle — well above the loan instalment alone.

Should You Take the Longest Tenure?

The 7-year maximum tenure minimises monthly outflow, which is why it is popular. The trade-off is higher total interest paid and a longer period where the outstanding loan balance may exceed the car's market value (especially given the depleted PARF values under Budget 2026 rules).

If the instalment amount at a shorter tenure is manageable, a 5-year loan reduces total interest by a meaningful amount. The rough calculation: at 2.78% flat, moving from 7 to 5 years on a S$96,000 loan saves approximately S$5,300 in total interest, but increases monthly payments by around S$380.

The Bottom Line

DBS, OCBC, and Maybank all cluster around 2.78%–2.98% flat rate for new car loans in Singapore. The key variables are whether your car falls in the 60% or 70% LTV band (determined by OMV), how the flat rate converts to an EIR (typically doubling the headline percentage), and whether the monthly total cost — loan plus running costs — fits your household budget. MAS caps tenure at 7 years and LTV at 60%–70%. The instalment is the visible cost; the EIR and total repayment figure are what actually matter.
