How Much Home Loan Can You Actually Afford on Your Salary?

Before you fall in love with a property, you need to answer one critical question: how much will the bank actually lend you? In the Philippines, home loan eligibility is heavily tied to your gross monthly income — and understanding the formula banks use can save you from wasted applications, disappointment, and months of delay.

This guide breaks down exactly how salary-based home loan calculations work, what Philippine banks look at, and how you can maximize your borrowing capacity — whether you're buying your first home or refinancing an existing loan.

The Golden Rule: The 30-35% Debt-to-Income Ratio

Almost every Philippine bank — BDO, BPI, Metrobank, Security Bank, PNB, RCBC, and others — follows the same core principle: your total monthly debt obligations should not exceed 30% to 35% of your gross monthly income. This is called your Debt-to-Income (DTI) ratio.

Here's what that means in practice:

Important: this cap includes all existing debt obligations — car loans, personal loans, credit card minimum payments, and any other active credit lines. If you're already paying 8,000 a month on a car loan, that amount is deducted from your available repayment capacity before your home loan is even assessed.

Salary-to-Loan Amount Reference Table

The table below estimates maximum loanable amounts based on gross monthly salary, assuming a 20-year loan term, an interest rate of 7% per annum, and no existing debt obligations. These are approximations — actual offers vary by bank and individual profile.

As you can see, the interest rate on your loan dramatically affects how much you can borrow. At a lower rate of 5.99% p.a. — the best rate currently available through Nook — your borrowing capacity increases meaningfully for the same monthly repayment.

How Interest Rate Affects Your Borrowing Capacity

Most Filipinos don't realize that refinancing to a lower rate doesn't just reduce your monthly payment — it can also increase how much you're effectively able to borrow for the same income level. Here's a concrete example:

Suppose you earn 80,000 per month with no existing debt. Your maximum repayment capacity is 24,000 per month. Here's how different interest rates translate into loanable amounts on a 20-year term:

That's a difference of nearly 690,000 in borrowing power simply by securing a better interest rate. For existing homeowners, this is exactly why refinancing matters — you can use our home loan refinance calculator to estimate how much you could save or how much additional borrowing capacity a lower rate would unlock.

Step-by-Step: How to Calculate Your Own Borrowing Capacity

Step 1: Determine Your Gross Monthly Income

Banks use your gross income (before tax and deductions), not your take-home pay. For employed borrowers, this is the amount on your Certificate of Employment and Compensation (COEC) or payslip. For self-employed individuals, banks typically look at the average of your last two years of net income after business expenses, as reflected in your ITR.

Step 2: Subtract Existing Monthly Debt Obligations

List all current monthly debt payments: car loans, personal loans, credit card minimums, salary loans. Subtract this total from your income-based maximum repayment capacity. The remainder is your available repayment budget for a home loan.

Step 3: Apply the Bank's Repayment Cap

Multiply your gross monthly income by 30% (conservative banks like Pag-IBIG) or 35% (many commercial banks). Then subtract your existing obligations from Step 2.

Step 4: Use a Loan Amortization Formula

With your available monthly repayment amount and the applicable interest rate, you can back-calculate the principal loan amount. The formula is: Loan Amount = Monthly Payment × [(1 - (1 + r)^-n) / r], where r is the monthly interest rate and n is the number of monthly payments. Most online calculators handle this automatically.

Step 5: Cross-Check Against the Property Value

Philippine banks typically lend up to 70% to 80% of the appraised property value (Loan-to-Value or LTV ratio). So even if your income supports a 4,000,000 loan, if the property appraises at 4,500,000, the bank will lend a maximum of 3,150,000 to 3,600,000. Always verify both constraints.

OFW and Dual-Income Borrowers: Special Considerations

For Overseas Filipino Workers (OFWs), banks generally accept remittance records and overseas employment contracts as proof of income. Many banks — including BDO, BPI, and Landbank — have dedicated OFW home loan programs. The same 30-35% DTI principle applies, but documentation requirements differ.

If you're applying as a couple or with a co-borrower, banks typically combine both incomes for the purpose of qualifying, which can significantly increase your maximum loanable amount. For example, if one spouse earns 60,000 and the other earns 40,000, the combined gross income of 100,000 is used — potentially qualifying you for a loan up to approximately 3,820,000 on a 20-year term at 7% p.a.

Pag-IBIG vs. Bank Loans: Key Differences

Pag-IBIG (HDMF) home loans use the same income-based qualifying logic but with some distinct features. The maximum loanable amount under Pag-IBIG is currently 6,500,000. Their repayment capacity limit is typically 35% of gross monthly income. Pag-IBIG also factors in your monthly contribution history and membership duration.

Commercial bank loans, by contrast, offer higher maximum loan amounts, faster processing in some cases, and more flexibility — but interest rates can vary widely. Shopping across banks is essential, and this is exactly where Nook adds value: by submitting your profile to multiple lenders simultaneously, you get competing offers without the legwork.

What Reduces Your Borrowable Amount?

Even if your salary looks strong on paper, several factors can reduce what banks are willing to lend:

Practical Example: Maria's Home Loan Calculation

Maria is a 34-year-old marketing manager in Makati earning 85,000 gross per month. She has a car loan with monthly payments of 9,500 and a credit card with a minimum payment of 2,000. She wants to know how much she can borrow for a condo in Pasig.

Step 1: Maximum repayment capacity at 35% DTI = 85,000 × 35% = 29,750

Step 2: Existing obligations = 9,500 + 2,000 = 11,500

Step 3: Available for home loan = 29,750 − 11,500 = 18,250 per month

Step 4: At 7% p.a. over 20 years, a monthly payment of 18,250 supports a loan of approximately 2,320,000

Step 5: The condo is priced at 3,200,000. At 80% LTV, the maximum bank loan is 2,560,000. Maria's income-based capacity of 2,320,000 is the binding constraint.

If Maria could refinance her car loan to a lower rate and reduce that payment by 2,000 per month, her available home loan repayment budget rises to 20,250 — and her maximum home loan jumps to approximately 2,580,000, bringing the condo within reach.

Already Have a Home Loan? Check If You're Overpaying

If you already own a home and are currently paying a rate above 7%, there's a good chance you qualify for significant savings through refinancing. The best rate available through Nook right now is 5.99% p.a. — a difference that can mean tens of thousands of pesos in savings every year.
