Home Loan Calculator Philippines Based on Salary

Philippine banks use your Gross Monthly Income (GMI) as the primary basis for determining your maximum home loan amount. The standard formula works like this:

1. Step 1 — Find your allowable monthly amortization: Most banks cap your monthly home loan payment at 30% of your GMI (some banks go up to 35% or 40% for higher-income borrowers).
2. Step 2 — Work backward from that amortization: Using the bank's prevailing interest rate and your chosen loan term (e.g., 20 years), the bank calculates the maximum loan principal that produces a monthly payment equal to or below that allowable amount.
3. Step 3 — Apply property and collateral limits: Most banks will also lend no more than 70%–80% of the appraised value of the property (the Loan-to-Value ratio or LTV), so your qualifying loan amount is the lower of the salary-based figure and the LTV-based figure.

For example, if your GMI is 80,000 per month, your allowable monthly amortization is about 24,000 (30% × 80,000). At an interest rate of 7% p.a. over 20 years, a monthly payment of 24,000 supports a loan of roughly 3,100,000.

The 30% gross income rule is the most widely used guideline in Philippine mortgage lending. It states that your monthly home loan amortization should not exceed 30% of your verified gross monthly income. This threshold exists to ensure borrowers can comfortably meet their mortgage obligations alongside other living expenses and financial commitments.

However, not all banks apply exactly 30%:

• BDO: Uses 30% GMI as the standard cap.
• BPI: Also uses 30% GMI, but may consider net disposable income (NDI) for borderline cases.
• Security Bank: Uses 30% for standard applications; may flex to 35% for high-income borrowers with clean credit histories.
• Metrobank: Typically 30%, with loan officers having some discretion.
• Pag-IBIG (HDMF): Uses a slightly different formula — the Net Take-Home Pay (NTP) after amortization must not fall below the minimum wage in the region where the borrower resides.

It's worth noting that some banks look at your net disposable income after deducting existing loan obligations (car loans, personal loans, credit card minimums). If you already carry debt, your effective borrowing capacity for a home loan will be reduced even if your gross salary is high.

On a gross monthly salary of 50,000, here's how your borrowing capacity looks across different scenarios:

Allowable monthly amortization: 30% × 50,000 = 15,000 per month

Notice that a lower interest rate directly increases how much you can borrow on the same salary — one reason refinancing can matter even before you buy a second property. If you already have a home loan and are paying 7% or more, switching to 5.99% p.a. could significantly change your monthly cash flow.

On a gross monthly salary of 100,000, your borrowing capacity roughly doubles compared to the 50,000 scenario:

Allowable monthly amortization: 30% × 100,000 = 30,000 per month

For households earning 100,000 per month, a 20-year loan at 5.99% p.a. can unlock close to 4,200,000 in borrowing power — versus roughly 3,880,000 at 7%. That 320,000 difference could be the gap between a condo and a townhouse, or between a smaller and larger unit.

Yes — and this is one of the most effective ways to increase your home loan eligibility in the Philippines. Most major banks allow co-borrowers (also called co-applicants) whose income is combined with the primary borrower's for qualification purposes. Common co-borrower arrangements include:

• Spouses: Accepted by all banks. Combined GMI is used as the basis for the 30% amortization rule.
• Parents or children: Accepted by most banks subject to age restrictions (the co-borrower's age plus the loan term usually cannot exceed 65–70 years).
• Siblings: Accepted by some banks (e.g., BPI, Security Bank) but not universally.

Example: If you earn 60,000/month and your spouse earns 50,000/month, your combined GMI is 110,000. Your allowable monthly amortization becomes 33,000 (30% × 110,000), which can support a loan of approximately 4,300,000–4,600,000 over 20 years depending on the rate — compared to just 2,300,000–2,600,000 on your income alone.

One important caveat: both borrowers' existing debts (credit card minimums, car loans, personal loans) will also be factored in, potentially reducing the net disposable income available for the mortgage.

Absolutely — and this is one of the most underappreciated aspects of mortgage math. Because your maximum allowable monthly payment is fixed by your salary (e.g., 30% of GMI), a lower interest rate means more of each payment goes to principal, which means the bank can lend you a larger amount for the same monthly cost.

Here's a concrete illustration for a borrower with a GMI of 80,000 per month (allowable amortization: 24,000/month) on a 20-year term:

• At 9.00% p.a. → maximum loan ≈ 2,660,000
• At 7.00% p.a. → maximum loan ≈ 3,100,000
• At 5.99% p.a. → maximum loan ≈ 3,360,000

That's a difference of 700,000 in borrowing power between a 9% loan and a 5.99% loan — on the exact same salary. This dynamic applies equally to refinancing: if you refinance your existing loan to a lower rate, your monthly payment drops, freeing up cash flow or shortening your repayment timeline.

While salary is the primary driver, Philippine banks assess several other factors that can raise or lower your effective borrowing limit:

• Employment type and tenure: Employed borrowers typically need at least 2 years with the same employer (or in the same industry for job changers). Self-employed borrowers need 2–3 years of documented business income, and banks may use a more conservative income figure.
• Credit history: A clean credit score (no defaults, no dishonored checks, no unresolved negative records with the Credit Information Corporation) can unlock higher LTV ratios and better rates. Negative records can result in outright rejection or lower loan amounts.
• Existing debt obligations: Banks subtract your current monthly debt payments (car loans, personal loans, credit card minimums) from your disposable income before applying the 30% rule. A borrower with a 50,000 salary and 10,000 in existing monthly debt commitments effectively has the borrowing power of a 17,000/month maximum amortization, not 15,000.
• Property appraisal value: The loan cannot exceed 70%–80% of the bank's appraised value of the property, regardless of your salary. If the bank appraises your target property at 4,000,000, the maximum loan is typically 2,800,000–3,200,000.
• Age: Most banks require that the loan be fully repaid before the borrower turns 65 or 70. A 50-year-old borrower may only qualify for a 15-year term, which raises monthly payments and reduces the qualifying loan amount.
• Down payment size: A larger down payment reduces the required loan amount and can sometimes improve approval chances or unlock better rates.

OFW (Overseas Filipino Worker) borrowers are a major segment of Philippine mortgage applicants, and most banks have specific processes for evaluating their income. Here's how it generally works:

• Documentation required: OEC (Overseas Employment Certificate), employment contract, last 3–6 months' proof of remittances (bank statements or remittance receipts), and a valid passport.
• Income conversion: Foreign currency income is converted to Philippine Peso using the bank's prevailing forex rate, often with a small conservative haircut.
• Sea-based vs. land-based: Sea-based OFWs (seafarers) may face slightly different treatment since their contracts are project-based. Banks typically require at least 2 continuous years of sea-based employment history.
• Pag-IBIG Fund: Pag-IBIG is often the most accessible lender for OFWs — voluntary Pag-IBIG members who have made at least 24 monthly contributions can apply for an HDMF housing loan of up to 6,000,000. The income documentation requirements are more flexible than commercial banks.
• Representative/Attorney-in-Fact: Since OFWs may be abroad during processing, most banks and Pag-IBIG allow a designated representative in the Philippines to process the application via a Special Power of Attorney (SPA).

The same 30% of GMI rule applies to OFWs, but with the converted peso equivalent of their foreign salary as the base figure.

Yes — refinancing can benefit existing homeowners in two key ways related to salary-based capacity:

1. Lower your monthly payment (same loan, more breathing room): If you're currently paying 8% or 9% and you refinance to 5.99% p.a., your monthly amortization drops significantly. For a 3,000,000 outstanding balance over 15 remaining years, moving from 8% to 5.99% saves roughly 3,500–4,000 per month. That freed-up cash flow can fund investments, education, or even an additional property.

2. Cash-out refinancing (borrow against your equity): Some banks offer cash-out refinancing, where you refinance for an amount higher than your outstanding balance and receive the difference in cash — useful for home improvements or other large purchases. Your salary still needs to support the new, higher monthly payment.

Refinancing does involve closing costs (appraisal fees, legal fees, documentary stamps, and sometimes a prepayment penalty on your old loan), so it's important to calculate your break-even point. Use Nook's refinance break-even calculator to find out exactly how many months it takes to recover your refinancing costs and start netting pure savings.

If your current salary-based borrowing capacity falls short of the property you want, here are practical, bank-approved strategies to improve your position:

1. Add a co-borrower: Including a spouse, parent, or sibling with a stable income directly increases your combined GMI and allowable amortization — often the single most impactful step.
2. Pay down existing debts first: Clearing credit card balances, personal loans, or a car loan before applying increases your net disposable income and raises your effective borrowing capacity.
3. Choose a longer loan term: Stretching from 15 to 25 years lowers the required monthly payment for the same loan amount, allowing a larger principal. Be aware this increases total interest paid over the loan life.
4. Target a lower interest rate: As shown above, the difference between 7% and 5.99% on a 20-year loan translates to significantly more borrowing power. Nook shops your application across multiple banks to find the lowest available rate — currently as low as 5.99% p.a.
5. Increase your down payment: A larger down payment reduces the loan amount needed, which makes approval easier even if it doesn't technically change your GMI-based cap.
6. Document all income sources: Part-time consulting income, rental income from another property, or business dividends can be included if properly documented (ITR, leases, etc.). Many borrowers leave income on the table by failing to document secondary earnings.
7. Build your credit profile: A strong credit record may qualify you for premium rate tiers at banks like Security Bank or BPI, which directly improves borrowing capacity as described above.
