One of the first questions every Filipino homebuyer asks is: "How much can I borrow based on my salary?" Philippine banks and Pag-IBIG use your monthly gross income to determine your maximum loanable amount — and getting this number right before you apply can save you from rejection, delays, and disappointment. Use this guide alongside Nook's free home loan calculator to get a clear picture of your borrowing power, whether you're buying your first home or refinancing an existing loan.
The general rule across BDO, BPI, Metrobank, RCBC, Security Bank, and most other Philippine lenders is that your monthly amortization should not exceed 30% to 40% of your gross monthly income. That single figure drives almost everything else — the loan amount you qualify for, the term you can choose, and the interest rate tiers available to you. Below, we answer the most common questions Filipino borrowers have about salary-based home loan calculations, with real numbers you can use right now.
Philippine banks determine your maximum loanable amount by working backwards from what you can afford to pay each month. Most lenders cap your monthly amortization at 30% to 40% of your gross monthly income. At 30%, a borrower earning 50,000 a month can afford a monthly payment of up to 15,000. At a 6% annual interest rate over 20 years, that 15,000 monthly payment supports a loan of roughly 2,090,000. At 40% of income, the same borrower could qualify for up to 2,785,000.
The exact percentage depends on the bank. BDO and BPI typically use 30–35%, while Security Bank and RCBC may go up to 40% for well-qualified borrowers. The safest approach is to use 30% as your base estimate, then check with multiple lenders — which is exactly what Nook does for you, for free.
The 30% rule is the lending industry's standard guideline that your total monthly housing cost — principal, interest, and in some cases insurance — should not exceed 30% of your gross monthly income. This rule protects both the borrower and the bank: it ensures you have enough income left over for living expenses, savings, and other obligations, reducing the risk of default.
Here's how the rule works in practice:
- Monthly gross income of 30,000 → maximum monthly amortization of 9,000
- Monthly gross income of 50,000 → maximum monthly amortization of 15,000
- Monthly gross income of 80,000 → maximum monthly amortization of 24,000
- Monthly gross income of 150,000 → maximum monthly amortization of 45,000
If you already have existing loan obligations (car loans, personal loans, credit card minimum payments), banks will subtract those from your available 30–40% before calculating your home loan capacity. Always declare all existing debts when applying.
Absolutely. The table below estimates the maximum home loan amount a borrower could qualify for at various salary levels, using a 6% annual interest rate and a 20-year term — figures that reflect competitive bank rates currently available through Nook. The monthly amortization cap is set at 30% of gross monthly income.
| Monthly Gross Salary | Max Monthly Payment (30%) | Estimated Max Loan (6%, 20 yrs) |
|---|---|---|
| 25,000 | 7,500 | 1,045,000 |
| 35,000 | 10,500 | 1,463,000 |
| 50,000 | 15,000 | 2,090,000 |
| 75,000 | 22,500 | 3,135,000 |
| 100,000 | 30,000 | 4,180,000 |
| 150,000 | 45,000 | 6,270,000 |
| 200,000 | 60,000 | 8,360,000 |
Note: These are estimates. Actual loanable amounts depend on the bank's assessment, your credit score, the appraised value of the property, and your total debt obligations.

Philippine banks almost universally use your gross monthly income — your salary before tax, SSS/PhilHealth/Pag-IBIG deductions — as the basis for computing your maximum loanable amount. This is the figure that appears on your Certificate of Employment (COE) and your Income Tax Return (ITR), which are the primary income documents banks require.
However, some banks will also look at your net take-home pay as a reasonableness check. If your mandatory deductions plus existing loan payments already consume a large portion of your gross income, the bank's credit analyst may apply a more conservative multiplier. Self-employed borrowers and freelancers are typically assessed based on their average monthly net income over the past two years, as computed from their ITR and audited financial statements.
For OFWs, banks accept employment contracts and remittance records, and generally use gross remittance income as the qualifying figure.
Yes — and this is one of the most effective ways to increase your borrowing power. Most Philippine banks allow spouses and immediate family members to be listed as co-borrowers, and their income is added to yours when computing the maximum monthly amortization you can collectively afford.
For example, if you earn 50,000 per month and your spouse earns 40,000 per month, your combined gross monthly income is 90,000. At 30%, your combined maximum monthly amortization would be 27,000 — which at 6% over 20 years supports a loan of approximately 3,760,000, compared to just 2,090,000 on your income alone.
Important notes for co-borrowing:
- Both borrowers' credit histories will be checked. A co-borrower with a poor credit record can hurt rather than help.
- Both borrowers are jointly and severally liable for the full loan amount.
- The property title will typically include both names.
- Some banks limit co-borrowers to spouses, parents, siblings, or children.
Pag-IBIG Fund uses a slightly different methodology from commercial banks. Your maximum loanable amount under the Pag-IBIG Housing Loan program is determined by three limits, and you receive whichever is lowest:
- The statutory maximum: Currently up to 6,500,000 for qualified borrowers.
- The appraised value of the property (typically 80–90% of appraised value).
- Your capacity to pay: Pag-IBIG uses the same 30–35% of gross monthly income guideline, applied to the loan term and the prevailing Pag-IBIG interest rate (which varies by loan amount).
Pag-IBIG interest rates are tiered based on loan amount. Loans up to 450,000 currently carry rates as low as 3% p.a., while larger loans are priced at market-competitive rates. Because Pag-IBIG rates on mid-to-large loan amounts can sometimes be higher than what commercial banks offer — especially after repricing — some borrowers refinance out of Pag-IBIG into a bank loan once their balance drops. Nook can help you compare both options.
Your monthly income is the starting point, but banks conduct a comprehensive credit assessment that includes several other factors:
- Credit score and credit history: Late payments on credit cards, personal loans, or previous home loans will reduce your qualifying amount or result in outright rejection. The Philippine credit bureau (TransUnion Philippines) maintains your credit record.
- Employment type and tenure: Regular employees with at least 2 years of tenure at the same company are viewed more favourably than probationary or contractual workers. Self-employed borrowers typically need 2–3 years of business history.
- Age: Banks cap the loan term so the loan is fully paid before you reach 65–70 years old. A 55-year-old borrower may only qualify for a 10–15 year term, which raises monthly payments and reduces the loanable amount compared to a 35-year-old.
- Existing debt obligations: Car loans, personal loans, and credit card minimum payments all reduce the portion of your income available for a home loan payment.
- Property appraisal: Banks lend up to 80–90% of the property's appraised value (loan-to-value ratio). Even if your income qualifies you for 5,000,000, the bank won't lend more than 80–90% of what their appraiser says the property is worth.
- Down payment: A larger down payment reduces the loan amount needed, which can make approval easier and may qualify you for better interest rates.
Your monthly amortization is calculated using the standard amortization formula, which accounts for your loan principal, the monthly interest rate, and the number of monthly payments. You don't need to do the math manually — Nook's home loan refinance calculator can compute this for you instantly.
For reference, here are estimated monthly amortizations for a 3,000,000 loan at various interest rates and terms:
| Interest Rate | 15-Year Term | 20-Year Term | 25-Year Term |
|---|---|---|---|
| 5.99% p.a. | 25,310 | 21,480 | 19,300 |
| 7.00% p.a. | 26,960 | 23,260 | 21,210 |
| 8.00% p.a. | 28,670 | 25,090 | 23,150 |
| 9.00% p.a. | 30,430 | 26,990 | 25,190 |
| 10.00% p.a. | 32,240 | 28,950 | 27,270 |
Notice how dramatically the interest rate affects your monthly payment. The difference between a 5.99% loan and a 10% loan on a 3,000,000 balance over 20 years is roughly 7,470 per month — or 89,640 per year. Over the life of the loan, that's nearly 1,790,000 in extra interest payments. This is why refinancing to a lower rate can be so powerful.
Using the 30% income rule and current competitive rates of around 6% p.a., here's what monthly gross income you'd need to comfortably qualify for common loan amounts:
| Target Loan Amount | Term | Est. Monthly Payment (6%) | Minimum Monthly Gross Salary (30% rule) |
|---|---|---|---|
| 1,500,000 | 20 years | 10,740 | 35,800 |
| 2,000,000 | 20 years | 14,320 | 47,735 |
| 3,000,000 | 20 years | 21,480 | 71,600 |
| 3,000,000 | 25 years | 19,300 | 64,335 |
| 5,000,000 | 20 years | 35,800 | 119,335 |
| 5,000,000 | 25 years | 32,170 | 107,235 |
| 8,000,000 | 20 years | 57,280 | 190,935 |
If your salary falls short, remember: extending the loan term reduces the monthly payment (and the required income), and adding a co-borrower's income can bridge the gap. Also, if you can make a larger down payment, the loan amount you need decreases accordingly.
Refinancing doesn't directly increase the amount you've already borrowed, but it can significantly improve your financial position in two important ways:
1. Lower monthly payments free up income. If you're currently paying 28,000 per month at 9% and you refinance to 5.99%, your payment on the same remaining balance might drop to 22,000 or less. That frees up 6,000 or more per month in cash flow — which improves your debt-to-income ratio and could qualify you for an additional loan if needed.
2. Cash-out refinancing. Some banks allow you to refinance for an amount higher than your current outstanding balance — up to the lender's loan-to-value limit on your property's current appraised value. If your home has appreciated significantly, you may be able to access equity as cash while still reducing your interest rate.
Most Filipino homeowners paying rates between 7% and 10% are strong candidates for refinancing. The best refinance rate currently available through Nook is 5.99% p.a. — and Nook's service is completely free to the borrower.
