Car loan refinancing replaces your current loan with a new one on better terms, usually a lower monthly instalment, less total interest, or both. Whether a refinance delivers those savings comes down to various factors:
- Your current loan settlement amount, including any applicable early settlement charges.
- The refinancing terms offered, including the interest rate, tenure and fees.
From eligibility and paperwork to a worked savings example and the step-by-step process, learn the crucial details for your car loan refinancing.

What Is Car Loan Refinancing in Singapore?
Definition of Car Loan Refinancing
Car loan refinancing replaces your existing loan structure with a new one on terms you prefer: a lower interest rate, a restructured tenure, or both. The new lender typically settles your outstanding balance directly with your existing financier, and from that point you repay the new lender on the terms you agreed to before signing.
Refinancing
Refinancing restructures the debt. The rate, tenure, or both may change. While the car stays with you, the obligation shifts to a new lender on terms you have negotiated in advance.

Singapore’s Environment in 2026
Two factors define car loan refinancing in Singapore:
- Car loans depend on the lender, your existing loan terms and the refinancing structure offered. If your current loan carries a higher rate than the refinancing options available to you, switching may reduce your borrowing costs after fees and settlement charges are taken into account.
- COE premiums, especially elevated rates, can affect used car valuations, which may form part of a lender's assessment of the vehicle and refinancing application.
Land Transport Authority (LTA) Records
Once refinancing is complete, the outgoing financier’s interest is discharged and the relevant vehicle financing records are updated to reflect the new financing arrangement, where applicable.
When Does Refinancing Make Sense?
Credit Profile
Credit Bureau Singapore (CBS) records credit and repayment information reported by participating banks and financial institutions. A record of on-time payments can support a stronger credit profile, which may improve your eligibility or the terms offered when you refinance.
The rate you can access today may be better than the one you signed for if:
- Your credit profile was thin or imperfect when you took out the original loan
- You have since maintained clean repayment
Loan Tenure Timing
The Rule of 78 is used in many traditional hire-purchase agreements and allocates more interest to the earlier repayment periods. This means the interest rebate available when you settle early may differ from a simple pro-rata calculation.
By mid-tenure, more of the loan has been repaid, but whether refinancing produces meaningful savings still depends on the actual settlement amount, applicable fees, new rate, and remaining tenure.
Current Interest Rates
For illustration, a 0.72 percentage-point difference between a 3.50% and 2.78% flat rate equates to S$432 a year on every S$60,000. Actual refinancing savings, however, should be calculated using your lender's full settlement quotation and the terms of the new loan.
Break-Even Analysis
One comparison drives the decision: projected interest savings versus total switching costs.
Switching costs typically include:
- Early settlement penalty charges vary by lender and loan agreement.
- Vehicle valuation fee may be required by the new lender to determine the current market value.
- Administrative fees charged by the new lender for processing the refinanced facility.
Compare your projected savings against all applicable switching costs before deciding whether refinancing makes financial sense.

MAS Rules: Total Debt Servicing Ratio (TDSR) Explained
TDSR measures the proportion of your gross monthly income used to service all your monthly debt repayments. For property loans, your total monthly debt commitments, including mortgage, car loan and credit card payments, generally cannot exceed 55% of your gross monthly income under the TDSR framework.
For car loans, TDSR is not a universal requirement. That said, many lenders still assess your ability to service a refinanced loan using their own credit policies, and some may consider a debt servicing ratio as part of that assessment.
Monthly obligations counted towards the ratio include:
- Car loan instalments
- Mortgage repayments (HDB or private property)
- Credit card obligations
- Personal loans, student loans, and any other secured or unsecured facilities
The strategic implication runs in both directions. A successful refinance that reduces your monthly car instalment directly lowers your total debt obligations, freeing up TDSR headroom for future property-backed loans or other financing opportunities.
Taking on additional debt before applying may increase your monthly obligations and affect the lender’s affordability assessment. Lenders run a fresh debt assessment at the point of application.
While tenure determines the size of your monthly instalment, it's the lender's overall debt assessment that determines whether your application is approved.
How Much Could You Save? An Example Scenario
Your actual refinancing savings depend on your current loan settlement amount, the refinancing rate and tenure, and any applicable fees. The simplified example below shows how a difference in flat interest rates affects borrowing costs when the financing amount and tenure are held constant.
*This is a simplified illustration of the rate difference and does not represent the actual savings on an existing car loan.
At these illustrative rates, the difference in interest is S$1,152 over four years, while the monthly instalment differs by S$24.
For an actual refinancing comparison, use your lender's full settlement quotation and compare it with the total cost of the new loan, including any early-settlement, valuation, administrative and other applicable fees. This gives you a more accurate view of whether refinancing leaves you better off overall.

Eligibility and Document Checklist
Who Can Refinance
Exact criteria differ across lenders, but in general, they include:
- Age: Some lenders require applicants to be at least 21 years old. Upper age limits vary by lender.
- Residency status: Horizon Financial Services currently offers car loan refinancing to Singapore Citizens and Permanent Residents only. Some bank lenders extend eligibility to foreigners holding valid Employment Passes.
- Minimum income: Income and documentation requirements vary by lender. Some lenders may request two years of IRAS Notices of Assessment from self-employed applicants.
- Vehicle condition: Lenders may consider factors such as the vehicle's age, condition, market value and remaining COE when assessing a refinancing application. Eligibility and the amount available depend on the lender's assessment and refinancing criteria.
- Loan tenure position: Available refinancing tenure varies by lender and may depend on factors such as the vehicle's age, remaining COE and the lender's financing criteria. Through Horizon Financial Services, the tenure available will depend on the financial institution and refinancing option you are matched with.
Documents You'll Need
Prepare the following before submitting an application:
- NRIC (front and back) for Singapore Citizens and PRs. Passport and Employment Pass for foreigners
- Latest computerised payslips or IRAS Notice of Assessment for salaried applicants
- CPF Contribution History Statement (12 months) as an alternative or supplementary income document
- Two years of IRAS Notices of Assessment for self-employed applicants
- Vehicle log card, which is retrievable from the LTA OneMotoring portal and confirms registration details and whether the COE is due for renewal
- Current loan settlement statement showing outstanding principal, settlement date, and full settlement amount
- Singpass/MyInfo: Some lenders accept a MyInfo pull in place of physical income documents, which may reduce the need to submit documents manually.
The Step-by-Step Process for Car Loan Refinancing
Step 1: Request a Full Settlement Statement from Your Current Lender
Contact your existing bank or financier and ask for a formal settlement quotation. This gives you the exact figure required to pay off your loan, including any applicable interest rebate and early-settlement fees. Without this number, any savings projection may be unreliable.
Step 2: Get a Vehicle Valuation
The new lender may require or obtain an updated vehicle valuation of your car. This is one factor they consider when determining how much they will advance against it. The lender or valuer will determine the vehicle’s valuation according to its assessment criteria. A broker like Horizon Financial Services can arrange this through their dealer network, cutting out the groundwork of sourcing an independent valuer.
Step 3: Compare Lenders and Rates
Look beyond the headline flat rate. The comparison points are effective interest rate, car loan tenure, processing fees, repayment flexibility, and early settlement terms on the new loan. Horizon Financial Services compares refinancing rates across major Singapore banks in one place, which saves the back-and-forth of approaching each lender individually.
Step 4: Submit Your Application
Where supported, Singpass/MyInfo may reduce the amount of information or documentation you need to submit manually. The new lender then runs eligibility checks.
Step 5: Approval and Signing
Once approved, you will complete and sign the financing documents with the lender. Depending on the refinancing arrangement, the new financier may settle the existing facility directly.
Step 6: Transition Period
Once the existing loan has been settled, the relevant vehicle financing records are updated to reflect the new financier, where applicable. Your new instalments will begin according to the terms of the refinanced loan. Follow your existing lender’s instructions on when to stop your current repayment arrangements.
Update your motor insurance. Your refinancing lender may require you to update the existing policy to reflect the new financing arrangement. Check with the lender and your insurer on any endorsement requirements before the refinancing is completed.
4 Common Mistakes to Avoid When Refinancing Your Car Loan
Mistake 1: Not Requesting a Settlement Statement First
A formal settlement statement gives you the lender’s exact settlement figure required to pay off the loan, including any early exit penalties or Rule of 78 adjustments. Without it, any savings calculation you run is based on an estimate of your outstanding balance. Projections built on estimates can overstate or understate the benefit of switching.
Mistake 2: Ignoring the Rule of 78
Some hire purchase agreements use the Rule of 78, which allocates a larger share of the total interest to the earlier repayment periods. As a result, the interest rebate available when you settle early may differ from a simple pro-rata calculation.
Your lender may also apply an early settlement charge or deduct part of the interest rebate, depending on the terms of your loan agreement. Use the formal settlement figure from your lender before deciding whether the potential refinancing savings justify the switch.
Mistake 3: Extending the Loan Tenure Unnecessarily
A longer tenure reduces your monthly instalment, but increases the total interest paid over the life of the loan. Extend tenure only when monthly cash flow is a constraint, not simply because the lower monthly number is more comfortable to look at.
Mistake 4: Refinancing on Negative Equity
Negative equity means the outstanding loan amount is higher than the car's current market value. This can also be a situation that accelerates with rapid depreciation or on vehicles approaching end-of-life.
Most lenders will not refinance a loan that exceeds the vehicle's value, because there is insufficient collateral to support the new facility. Before starting an application, check your outstanding balance against a current market valuation to confirm that equity exists to refinance against.

Frequently Asked Questions
Can I refinance my car loan if I have a low credit score in Singapore?
Refinancing your car loan may still be possible with a less-than-perfect credit history, although your credit profile is one factor lenders may consider when assessing eligibility and the terms offered. Different lenders use different credit criteria, and a broker can help you compare available options across multiple financiers. Improving your repayment record before applying and checking your CBS report for errors beforehand both strengthen your position.
What is the Rule of 78 and how does it affect my settlement?
The Rule of 78 is a method of allocating interest charges across a loan's payment periods, with more interest assigned to earlier payments than later ones. Because of this front-loading, settling early results in a borrower paying more interest than a simple pro-rata calculation would suggest, and the rebate calculation will depend on your loan agreement.
Is there a minimum holding period before I can refinance my car?
There is no universal statutory minimum holding period before refinancing a car loan. However, lenders may apply their own eligibility criteria or early-settlement terms, and some may impose early repayment charges that reduce or eliminate the savings from switching. Check your existing loan agreement and the refinancing lender’s requirements before applying.
What are the typical fees for car loan refinancing in Singapore?
The main cost categories may include processing fees from the new lender, early settlement penalty from your current bank, and vehicle valuation fees where a valuation is required. The size of each depends on your outstanding loan balance, your existing loan agreement's settlement terms, and the lender you are switching to. For a clear picture of what applies to your situation, consult with Horizon Financial Services before committing to any application.
Will refinancing my car loan affect my mortgage application (TDSR)?
Refinancing can positively or negatively affect a mortgage application depending on how it changes your monthly debt obligations. If the refinanced car loan reduces your monthly instalment, it frees up TDSR headroom for a home loan. If you extend the tenure without a meaningful rate reduction, your monthly obligations may not shift enough to make a material difference.
Timing also matters. Applying for both a refinanced car loan and a new mortgage close together may result in separate credit assessments for each application.
What happens to my motor insurance when I switch lenders?
You generally do not need to buy a new motor insurance policy when refinancing. However, your lender may require you to update the existing policy to reflect the new financing arrangement. Check with the refinancing lender and your insurer on any endorsement requirements before the new loan is completed.
Do I need to be the original registered owner of the car to refinance?
In hire purchase arrangements, the car is registered in the name of the hirer, meaning you appear as the owner on LTA records while the financier retains legal interest in the vehicle until the car loan is repaid. As a general rule, the refinancing applicant should be the registered owner on LTA records, since the new lender is taking over the legal interest in the same vehicle. If ownership has changed or there is a discrepancy in the records, confirm with your broker before proceeding, as this will need to be resolved before an application can go through.
