Home Loan Calculator Philippines Based on Salary: How Much Can You Borrow?

Philippine banks determine how much home loan you can borrow by applying a debt-to-income (DTI) ratio — typically capped at 30% to 40% of your gross monthly income. This means your total monthly loan obligation (principal + interest) must not exceed that percentage of what you earn before taxes and deductions.

For example, if your gross monthly salary is 80,000, a bank applying a 30% DTI limit would allow monthly repayments of up to 24,000. They then work backwards — using the applicable interest rate and loan term — to arrive at the maximum loanable amount.

It's important to note that banks look at your total monthly debt obligations, not just your home loan. If you already have a car loan or credit card minimum payments, those are factored in and will reduce the amount you can borrow for a home.

The standard approach used by most Philippine lenders follows these steps:

1. Determine your allowable monthly amortisation: Multiply your gross monthly income by the DTI limit (commonly 30%). Example: 60,000 × 30% = 18,000 per month.
2. Choose your loan term and interest rate: Most banks offer terms of 10 to 25 years. A longer term means lower monthly payments, which lets you borrow more.
3. Use a present value formula or loan table: At a rate of 7% p.a. over 20 years, a monthly payment of 18,000 corresponds to a loanable amount of approximately 2,270,000.

As a rough rule of thumb, many borrowers use a multiplier of 100 to 130 times their monthly allowable amortisation as a quick estimate. So if your allowable monthly payment is 20,000, you could potentially borrow between 2,000,000 and 2,600,000 depending on the rate and term.

Keep in mind this is an estimate. Your actual approval depends on the bank's specific guidelines, your credit history, and the property's appraised value.

With a gross monthly salary of 50,000, here's how the numbers typically work out:

• Allowable monthly amortisation (30% DTI): 15,000
• At 7% p.a. over 20 years: You could borrow approximately 1,890,000
• At 7% p.a. over 25 years: Approximately 2,120,000
• At 5.99% p.a. over 20 years (Nook's best available rate): Approximately 2,090,000

If your bank applies a more generous 35% DTI ratio, your allowable monthly payment rises to 17,500, which increases your borrowing capacity to roughly 2,200,000 to 2,470,000 depending on the term.

At a salary of 50,000, you are well-positioned to finance a mid-range condominium unit or a modest house-and-lot in many Philippine cities. If you already have a home loan and are paying a rate above 7%, refinancing through Nook could meaningfully reduce your monthly amortisation — check how much you could save.

A gross monthly income of 30,000 is at the lower end of most bank thresholds, but home ownership is still achievable — particularly through Pag-IBIG (HDMF), which has more flexible income requirements than commercial banks.

• Allowable monthly amortisation (30% DTI): 9,000
• At 7% p.a. over 20 years: Approximately 1,134,000
• At 7% p.a. over 25 years: Approximately 1,273,000
• Via Pag-IBIG at 6.5% over 25 years: Approximately 1,350,000

Most major commercial banks (BDO, BPI, Metrobank) require a minimum gross monthly income of around 40,000 to 50,000, so at 30,000 your best options are Pag-IBIG housing loans or in-house financing from developers. A co-borrower (spouse or family member) with verifiable income can also significantly boost your combined eligibility.

Philippine banks and lenders almost universally use gross monthly income — your salary before income tax, SSS/GSIS, PhilHealth, and Pag-IBIG deductions — as the basis for computing your home loan eligibility.

This is actually advantageous for borrowers, since your gross pay is always higher than your net take-home. For a salaried employee earning a gross of 70,000 per month, the 30% DTI threshold gives an allowable amortisation of 21,000 — even if their actual net pay is only 56,000 after deductions.

For self-employed individuals and business owners, banks typically look at your net income after business expenses as declared in your Income Tax Return (ITR). They may average the last 2 years of ITR to arrive at a stable monthly income figure. Inconsistent income documentation is a common reason self-employed applicants face lower loan approvals or outright rejections.

While all banks follow the same general DTI framework, the specific parameters vary — and those differences can meaningfully affect how much you can borrow:

Note: These figures are indicative and subject to change. Interest rates also vary by bank and repricing period — you can see current rates on our Philippines bank loan interest rates guide. Because requirements differ so much between lenders, comparing multiple banks is always worth doing before you apply.

Yes — and this is one of the most effective strategies for increasing your borrowing capacity. Philippine banks allow co-borrowers (typically a spouse, parent, sibling, or child) whose income is added to yours when computing DTI eligibility.

Here's how it works in practice: if you earn 45,000 gross per month and your spouse earns 35,000, your combined gross income is 80,000. At a 30% DTI, the allowable monthly amortisation becomes 24,000 — compared to just 13,500 on your income alone. This can increase your borrowing capacity by 500,000 to 1,500,000 or more, depending on the loan term and interest rate.

Key requirements for co-borrowers:

• Must be a Filipino citizen
• Must meet the bank's minimum age and income documentation requirements
• Will appear on the loan documents and be equally liable for repayment
• For married couples, the spouse is typically required to be a co-borrower even if only one income is being used

Salary is the primary driver, but banks evaluate several other factors when determining your final loan amount:

• Credit history: A clean credit record with no defaults or late payments signals lower risk. Banks check with the Credit Information Corporation (CIC) and internal records.
• Existing debt obligations: Outstanding car loans, personal loans, or credit card balances reduce your DTI headroom.
• Property appraised value: Banks typically lend up to 70% to 80% of the property's appraised value (Loan-to-Value or LTV ratio). Even if you qualify for 3,000,000 based on salary, the bank won't lend more than 80% of what their appraiser says the property is worth.
• Employment stability: Permanent employees with at least 1–2 years of tenure are viewed more favourably than probationary or contractual workers.
• Age: Your loan term is typically limited so that the final payment falls before your 65th or 70th birthday (depending on the bank).
• Industry and employer: Some banks assign risk weights based on the sector you work in.

All of these factors combined determine your final approval — not just the salary-based computation.

When you refinance an existing home loan, the income requirements are similar to those for a new loan — banks still assess your gross monthly income and apply a DTI ratio. However, there are a few key differences:

• Lower principal balance: Since you've been paying down your loan, the outstanding amount you need to refinance is lower than your original loan. This means your required salary to qualify may actually be lower than when you first borrowed.
• Existing payment history: Demonstrating that you've made consistent repayments on your current mortgage works in your favour during refinancing assessment.
• Rate improvement = lower payments: If you refinance from 8% to 5.99% p.a. on a 3,000,000 balance over 15 years, your monthly payment drops from approximately 28,680 to 25,320 — a saving of over 3,300 per month. This lower obligation also makes it easier to meet DTI requirements.

Refinancing through Nook is 100% free to you as a borrower — Nook is compensated by the bank, not the homeowner. To understand what documentation you'll need, see our guide on home loan refinance requirements in the Philippines.

Income documentation requirements vary slightly by bank and employment type, but the standard documents are:

For salaried employees:

• Latest 1–3 months' payslips
• Certificate of Employment (COE) with salary details
• Latest ITR (BIR Form 2316) or BIR-stamped ITR Form 1700
• Company ID or employment contract (some banks)

For self-employed individuals / business owners:

• BIR-stamped ITR (Form 1701) for the last 2 years
• Audited Financial Statements for the last 2 years
• Business registration documents (DTI, SEC, Mayor's Permit)
• Bank statements for the last 6–12 months

For OFWs:

• Proof of employment abroad (contract, POEA documentation)
• Latest 3–6 months' remittance records
• Passport with valid visa
• Special Power of Attorney (if applying through a representative)

Having complete and accurate income documents ready before you apply significantly speeds up the process and improves your chances of approval at the best available rate.
