One of the most common questions Filipino homeowners ask when exploring refinancing is whether their existing car loan will get in the way. The short answer is: it depends — but having a car loan does not automatically disqualify you. Philippine banks evaluate refinancing applications holistically, looking at your total debt obligations relative to your income. Understanding how lenders calculate this, and how to position your application, can make the difference between an approval and a rejection.
At Nook, we work with multiple Philippine banks simultaneously, which means we can match you with the lender whose debt-to-income thresholds and credit policies best fit your situation. With refinance rates starting as low as 5.99% p.a., even borrowers with active car loans are unlocking significant monthly savings. This guide answers every key question about refinancing your home loan when you have an outstanding car loan.
Yes, you can — and many Filipinos successfully do it every month. Having an active car loan does not automatically disqualify you from refinancing your home loan in the Philippines. What matters to banks is your overall financial picture: your gross monthly income, your total monthly debt obligations (including the car loan), and whether the combined figure stays within their acceptable debt-to-income (DTI) ratio, typically 40% to 50% of gross monthly income.
For example, if you earn 150,000 per month, a bank allowing a 40% DTI would permit up to 60,000 in total monthly debt payments. If your car loan costs 15,000 per month, you would still have room for a home loan monthly amortization of up to 45,000 — enough to service a sizeable refinanced mortgage. The key is knowing which lender's policy fits your numbers, which is exactly what Nook helps you figure out at no cost.
The debt-to-income ratio is the single most important calculation a Philippine bank performs when assessing your refinancing application. It compares your total monthly debt payments — including your proposed new home loan amortization, car loan, credit card minimum payments, and any other loans — against your gross monthly income before tax.
The formula is straightforward: DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100. Most Philippine banks set their maximum allowable DTI at between 40% and 50%. If your DTI after including all debts exceeds this threshold, the bank will either reduce the loan amount they are willing to offer or decline the application. Keeping your DTI in check — even with a car loan in the picture — is the single most effective thing you can do to improve your refinancing chances.
Every peso you pay monthly on your car loan reduces the amortization capacity available for your home loan. Here is a practical example using common figures:
Assume you earn 200,000 per month gross and the bank applies a 40% DTI ceiling, giving you 80,000 in total allowable monthly debt. If your car loan costs 20,000 per month, your effective home loan capacity drops to 60,000 per month. At a refinance rate of 5.99% p.a. over 20 years, a monthly amortization of 60,000 supports a loan of roughly 8,400,000 — compared to roughly 11,200,000 if you had no car loan. That is a reduction in borrowing capacity of approximately 2,800,000. The impact scales with your car loan repayment amount, so a smaller or nearly-paid-off car loan has far less effect on your refinancing power than a large, newer one.
Flexibility varies significantly across lenders, and policies change regularly. In general, larger universal banks such as BDO, BPI, Metrobank, and Security Bank tend to have more structured DTI caps but also more sophisticated income assessment tools, which can work in your favour if you have additional income streams like rental income, freelance earnings, or business income. Some banks allow these supplementary income sources to be included at 50% to 70% of their value, effectively boosting your qualifying income.
Thrift banks and smaller commercial banks sometimes apply slightly looser guidelines for well-secured refinancing applications — particularly when the loan-to-value ratio is low (meaning you have substantial equity in your home). Pag-IBIG (HDMF) has its own set of criteria and can be a strong option for some borrowers, though private banks often offer more competitive rates. Because Nook works across the full spectrum of Philippine lenders, we can identify which institution is most likely to approve your specific profile without you having to approach each bank individually.
Yes. All Philippine banks pull a credit report from the Credit Information Corporation (CIC) as part of the refinancing process. This report will show your car loan balance, monthly payment, payment history, and remaining term. Banks use this data to calculate your DTI and to assess your reliability as a borrower.
This is actually good news if you have been paying your car loan consistently and on time — it demonstrates responsible debt management, which strengthens your refinancing application. Conversely, if you have missed car loan payments or have been persistently late, this will raise red flags for the home loan underwriter. If you have concerns about your credit history more broadly, our guide on how to refinance your home loan with bad credit in the Philippines covers practical steps to improve your standing before applying.
It depends on how close you are to the end of your car loan term and how much it is affecting your DTI. As a general rule: if you have 12 months or fewer remaining on your car loan, many banks will exclude it from the DTI calculation entirely — because the remaining obligation is short enough not to be considered a long-term liability. In this case, waiting until the car loan is settled (or nearly settled) before applying can meaningfully improve your qualifying income picture.
However, if you still have 3 to 5 years on your car loan, paying it off early may not make financial sense — especially if your car financing rate is lower than your home loan rate. In that scenario, it is often better to apply for refinancing now, letting the interest savings from the lower home loan rate work in your favour immediately, rather than waiting years and continuing to pay your current (likely higher) mortgage rate. Nook's advisors can model both scenarios using your actual numbers to help you decide which path saves you more money overall.
Most Philippine banks set a maximum DTI of 40% to 50% of gross monthly income for home loan refinancing applications. Here is how the threshold typically breaks down by lender type:
Universal and commercial banks (BDO, BPI, Metrobank, Security Bank, RCBC, UnionBank, Chinabank): Generally 40% to 45% DTI ceiling. Some will stretch to 50% for borrowers with strong credit histories, substantial home equity, or stable salaried employment with a reputable company.
Government and specialised lenders (Pag-IBIG/HDMF, Landbank): Pag-IBIG uses a slightly different formula but broadly aligns with a 35% to 40% income-based repayment guideline. Landbank applies similar conservative ratios for its home loan products.
Thrift banks (PSBank, EastWest Bank, Robinsons Bank): May offer slightly more flexibility on a case-by-case basis, particularly for borrowers with low LTV ratios (high home equity). Because these thresholds shift based on your full profile, Nook assesses your DTI across all potential lender partners before recommending which to apply to.
When you apply to refinance your home loan, the bank will require documentation of all existing liabilities, including your car loan. Typically you will need to provide:
- Latest Statement of Account (SOA) from your car loan bank or financing company showing the outstanding balance and monthly amortization
- Latest 3 to 6 months of bank statements showing car loan debit transactions (to verify payment consistency)
- Loan payment history or amortization schedule if available
These documents allow the underwriter to calculate your DTI accurately and verify that you are current on your car loan payments. Nook helps you organise and prepare all required documentation upfront, reducing the chance of delays or requests for additional information from the bank — one of the most common causes of application friction in the Philippines.
Potentially a significant amount. Most Filipino homeowners are currently paying between 7% and 10% p.a. on their existing home loans. Refinancing to 5.99% p.a. through Nook can produce substantial monthly and lifetime savings — and your car loan does not change those numbers as long as you qualify.
Consider this example: a homeowner with a 5,000,000 outstanding home loan balance at 8.5% p.a. over 20 years pays approximately 43,600 per month in amortization. Refinancing the same balance to 5.99% p.a. over 20 years reduces the monthly payment to approximately 35,700 — a saving of around 7,900 per month, or 94,800 per year. Over the remaining loan term, total interest savings can exceed 1,800,000. A car loan does not eliminate these savings; it simply needs to be factored into the DTI calculation to confirm eligibility. Nook can run your specific numbers in minutes, for free, so you know exactly what you stand to save.
Nook is the Philippines' first digital mortgage broker, and our entire model is built around finding the right lender for your specific financial profile — including borrowers who carry car loans or other active credit obligations. Here is how we help:
Multi-lender comparison: We assess your DTI and financial profile against the criteria of multiple Philippine banks simultaneously, identifying which lenders are most likely to approve your application at the best available rate.
Income optimisation: If you have supplementary income (rental, freelance, business), we know which banks allow this to be included and at what percentage — potentially pushing your DTI into an approvable range even with a car loan.
Application preparation: We help you compile and present your documents — including car loan statements — in the format each bank prefers, reducing back-and-forth and speeding up approval timelines.
Zero cost to you: Nook's service is 100% free to the borrower. We are compensated by the bank only if your loan is successfully approved and disbursed, so our incentive is entirely aligned with getting you the best outcome. Whether you are refinancing a house loan in the provinces or exploring options like moving from Pag-IBIG to a private bank for a lower rate, Nook can map the right path for your situation.
