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

Philippine banks determine your maximum home loan amount using a debt-to-income (DTI) ratio — specifically, they look at what monthly amortisation you can comfortably afford relative to your gross monthly income. The standard benchmark across most major banks (BDO, BPI, Metrobank, Security Bank, RCBC, and others) is that your total monthly loan obligations should not exceed 30% to 35% of your gross monthly income.

From that maximum allowable monthly payment, the bank works backwards using the loan's interest rate and term to arrive at the principal amount you can borrow. The formula looks like this:

• Step 1: Multiply your gross monthly income by 30% (or 35% for some banks) to get your maximum monthly amortisation.
• Step 2: Subtract any existing monthly loan obligations (car loans, personal loans, credit card minimums) from that figure.
• Step 3: Use a loan amortisation formula — or a home loan calculator Philippines based on salary — to convert the remaining payment capacity into a principal loan amount, given the bank's interest rate and your chosen term.

For example, if your gross monthly income is 80,000 pesos, your maximum allowable amortisation is around 24,000 to 28,000 pesos per month. At an interest rate of 6.5% over 20 years, that translates to a loanable amount of roughly 3,200,000 to 3,700,000 pesos.

The 30% rule is the most widely applied guideline among Philippine banks when assessing home loan affordability. It states that your monthly home loan amortisation — and all other recurring debt obligations combined — should not exceed 30% of your gross monthly income.

Here is a quick reference table based on this rule:

*Approximate loanable amounts assume a 6.5% interest rate, 20-year term, and no existing debt obligations. Actual offers vary by bank.

Some banks like Security Bank and BPI may allow up to 35% DTI for borrowers with strong credit profiles or large down payments. Pag-IBIG (HDMF) applies a slightly different table-based approach (see the Pag-IBIG question below).

Keep in mind that the 30% rule applies to your total debt load — if you already have a car loan costing 8,000 per month, your available amortisation budget for a home loan is reduced to just 22,000 per month (at a 30,000 cap on a 100,000 salary).

On a gross monthly salary of 50,000 pesos, most Philippine banks will allow a maximum monthly amortisation of around 15,000 pesos (30% DTI), assuming you have no other existing loans.

Here's how that translates into a loanable amount depending on the interest rate and loan term:

As you can see, the interest rate significantly affects your borrowing power. At 5.99% over 20 years, you can borrow around 2,100,000 pesos — but at 9%, that drops to 1,680,000 pesos for the same monthly payment and term. This is why understanding current home loan interest rates in the Philippines is so important before you commit to a lender.

If you already have a 5,000 peso monthly car loan obligation, your net amortisation capacity drops to 10,000 per month, reducing your loanable amount by roughly 25 to 30%.

A gross monthly income of 30,000 pesos gives you a maximum monthly amortisation budget of roughly 9,000 pesos under the standard 30% rule. This is on the lower end for bank home loans, which is why many Filipinos at this income level turn to Pag-IBIG (HDMF) as their primary option.

Here is what 9,000 pesos per month can buy you in terms of loan principal:

Practical considerations for this income level:

• Most bank home loans have a minimum loanable amount of 1,000,000 to 1,500,000 pesos — you may be at or near this floor.
• Pag-IBIG offers rates as low as 6.5% for qualified low-to-moderate income members and allows terms up to 30 years, which can stretch your capacity.
• A co-borrower (spouse or parent) can significantly increase your combined qualifying income.
• A larger down payment (20% or more) reduces the principal needed and can put more properties within reach.

Yes — Pag-IBIG (HDMF) uses a slightly different approach compared to commercial banks. Instead of a pure DTI percentage, Pag-IBIG uses a net disposable income (NDI) method combined with a fixed multiplier table.

Here is how Pag-IBIG computes your maximum loanable amount:

1. Gross monthly income minus mandatory deductions (SSS/GSIS, PhilHealth, Pag-IBIG contributions, income tax) = Net Monthly Income
2. Net Monthly Income minus estimated living expenses (typically 30–40% of net income for a standard household) = Net Disposable Income (NDI)
3. The allowable monthly amortisation is set at a maximum of 35% of gross monthly income OR the full NDI, whichever is lower
4. Pag-IBIG then applies its published amortisation factor table to convert the monthly payment into a principal amount based on the applicable interest rate tier and term

Pag-IBIG interest rate tiers (2026):

• Loans up to 450,000: 5.375% to 6.5% (depending on term)
• Loans 450,001 to 1,500,000: 6.5% to 7.0%
• Loans 1,500,001 to 3,000,000: 7.5% to 8.0%
• Loans above 3,000,000 (maximum 6,000,000): market-based rates

The key advantage of Pag-IBIG is the lower rate for smaller loan amounts and the availability of 30-year terms, which reduces monthly amortisations and makes homeownership accessible for lower-income earners.

Philippine banks primarily use your gross monthly income — your salary before deductions for income tax, SSS, PhilHealth, and Pag-IBIG contributions — as the base for computing your home loan eligibility. This is the standard across BDO, BPI, Metrobank, Security Bank, RCBC, UnionBank, Chinabank, PSBank, EastWest Bank, and most other lenders.

However, there are important nuances:

• Employed borrowers: Banks use gross monthly salary as declared on your Certificate of Employment (COE) and confirmed by your latest ITR (Income Tax Return) and payslips.
• Self-employed borrowers: Banks look at your net income after business expenses as declared in your ITR — typically averaged over the last 2 years. Some banks apply a further discount of 10–20% to account for income variability.
• OFWs (Overseas Filipino Workers): Banks accept remittance records and employment contracts. Gross income is typically used, but some banks apply a currency conversion buffer for foreign-currency earners.
• Freelancers and mixed-income earners: Banks are more conservative here, often requiring 2 years of consistent income documentation and sometimes using only 70–80% of declared income in their computation.

For the most accurate calculation, always input your gross monthly income when using a home loan calculator Philippines based on salary — but keep in mind that your actual offer may be slightly lower if your income source is deemed irregular by the bank's underwriter.

Yes — and this is one of the most effective ways to increase your maximum loanable amount. Philippine banks allow co-borrowers (typically a spouse, parent, sibling, or child) whose income can be combined with yours to raise the total qualifying income.

How combined income works:

• Both borrowers' gross monthly incomes are added together to form the combined qualifying income.
• The 30–35% DTI rule is then applied to the combined figure.
• Both borrowers are equally liable for the loan and will both appear on the title (in most bank policies).

Example: You earn 50,000 per month and your spouse earns 40,000 per month. Your combined gross income is 90,000 pesos. At 30% DTI, your maximum monthly amortisation rises to 27,000 pesos — compared to just 15,000 on your salary alone. At 6.5% over 20 years, that increases your loanable amount from approximately 2,020,000 to approximately 3,630,000 pesos.

Things to note about co-borrowers:

• The co-borrower's existing debts are also factored into the DTI calculation, which could offset the income gain.
• Not all banks require the co-borrower to be an immediate family member — some accept non-related co-borrowers for investment properties.
• Pag-IBIG similarly allows joint borrowers, with both members' contribution histories taken into account.

While your monthly income is the primary driver of your maximum loanable amount, Philippine banks consider several additional factors that can increase or decrease the final approved amount:

• Credit history: A strong credit record with no defaults, late payments, or overleveraged credit cards signals lower risk to lenders and can result in higher loan offers or better rates. Banks check the Credit Information Corporation (CIC) database.
• Appraised property value: Banks typically lend up to 80% of the property's appraised value (Loan-to-Value or LTV ratio). Even if your income supports a 5,000,000 loan, the bank won't lend more than 80% of what their appraiser says the property is worth.
• Employment tenure: Most banks require at least 2 years of continuous employment (or 2 years in business for self-employed applicants). Probationary employees are generally not eligible.
• Age at loan maturity: Your loan term cannot extend beyond age 65 (for most banks) or age 70 (for some). A 55-year-old applicant can therefore only take a maximum 10–15 year term, which raises monthly payments and reduces borrowing power.
• Down payment amount: A larger down payment reduces the principal you need to borrow, making it easier to stay within your DTI limit and potentially unlocking lower interest rates.
• Nature of property: Condominiums and raw lots may attract slightly tighter LTV ratios (60–70%) compared to house-and-lot properties.
• Bank relationship: Existing depositors or payroll account holders at a particular bank may receive preferential treatment in underwriting.

Choosing a longer loan term directly increases the amount you can borrow for the same monthly payment — because the principal is spread over more years, each monthly instalment is smaller. This is a legitimate strategy to qualify for a larger loan when your income is the binding constraint.

Impact of term length on loanable amount (at 30,000/month max amortisation, 6.5% rate):

The trade-off is significant: a 25-year term lets you borrow 1,900,000 more than a 10-year term — but you pay roughly 3,500,000 more in total interest. The right answer depends on your priorities:

• If your goal is to maximise the property you can afford now, a longer term gives you more borrowing power.
• If your goal is to minimise total cost of ownership, a shorter term wins decisively.
• A middle-ground strategy: take a 20–25 year term to qualify for the loan, then make prepayments whenever cash flow allows. Use our home loan prepayment calculator to see how even small extra payments can dramatically cut your total interest bill.

If the salary-based calculator shows you can't quite borrow enough for the property you want, here are the most effective strategies Filipino borrowers use to increase their loanable amount:

1. Add a co-borrower: Combining incomes with a spouse, parent, or sibling is the single fastest way to increase your qualifying amount. Even a part-time co-borrower earning 20,000 a month can add 500,000 to 800,000 in borrowing capacity.
2. Pay down existing debts before applying: Every peso you eliminate from monthly debt obligations frees up amortisation capacity. Clearing a 5,000/month car loan effectively adds 5,000 to your available housing budget.
3. Increase your down payment: If you can put down 30% instead of 20%, the principal required is smaller — you can hit the property price you want with a lower loan amount that fits your income.
4. Choose the right bank: Different banks apply different DTI ceilings. Some use 30%, others 35%. Applying through a broker like Nook lets you compare multiple banks simultaneously and find the lender most likely to approve your target amount.
5. Document all income sources: Rental income, freelance earnings, dividends, and allowances can sometimes be included if properly documented. Ask your bank or broker what supplementary income they accept.
6. Refinance your existing home loan for a lower rate: If you already own property, refinancing to a lower rate can free up monthly cash flow — and if you need to borrow more, a lower rate means a higher principal for the same monthly payment. If you're currently paying 7% or more, check whether you qualify for rates as low as 5.99% through Nook — the refinance break-even calculator can show you how quickly the savings add up.
