Free Pag-IBIG Housing Loan Calculator

Understanding the Pag-IBIG Housing Loan Calculator

The Pag-IBIG Housing Loan Calculator is a versatile online tool designed to help Filipino borrowers estimate their borrowing capacity and plan their monthly repayments when applying for a home loan through the Home Development Mutual Fund (HDMF), commonly known as Pag-IBIG. Whether you need a Philippines housing loan calculator to evaluate property affordability or a Pag-IBIG monthly amortization calculator to break down your future payments, this tool provides quick, reliable estimates to guide your decisions before you visit a Pag-IBIG branch, meet a real estate agent, or talk to a property developer.

In addition to computing the maximum loanable amount based on property value, the calculator can also determine how much you can borrow based on your gross income – and it works in reverse, showing the required income needed for a given loan. This makes it an excellent HDMF housing loan calculator for pre‑qualification and budgeting.

The information presented here is for educational planning purposes. Actual loan approvals and terms depend on Pag-IBIG’s official evaluation, and additional fees may apply.

How to Use the Calculator

The tool serves three main functions. Each is accessed by entering the relevant values into the inputs provided.

1. Loanable Amount Based on Property Value

Enter the estimated market value of the property you intend to buy. The calculator immediately applies the appropriate loan‑to‑value (LTV) ratio (explained below) and displays the maximum amount Pag-IBIG can lend you.

2. Monthly Amortization for a Given Loan

Once you have a target loan amount (which cannot exceed the loanable amount computed above), follow these steps:

• Input the loan amount you wish to borrow.
• Choose the repayment period – from as short as 1 year up to 30 years.
• Select a fixed pricing period. This is a set number of years during which the interest rate remains constant, regardless of market changes. For example, choosing a 5‑year fixed period locks in a rate of 6.500% for those first 5 years. Afterward, Pag-IBIG will assign a new rate (possibly higher or lower). If you expect rates to rise above 9.750% later, you may opt for the 30‑year fixed period when your repayment term is also 30 years.

After these selections, the tool shows your monthly amortization (principal and interest) for the chosen term. It also calculates required gross annual and monthly income to qualify for that loan. If you want to see additional details – such as the estimated equity, monthly interest, and insurance premium – answer “Yes” to the “Show other calculated variables” prompt.

3. Loanable Amount Based on Income

Clear the loan amount field, then enter your gross monthly income (or annual income). The calculator will estimate the maximum loan you can obtain under the same fixed‑pricing period and term. This works as a reverse‑calculation feature, helping you determine the loan size your salary can support.

Note: Pag-IBIG sets a hard cap of ₱6,000,000 on any housing loan. The tool will alert you if the entered or calculated amount exceeds this limit.

Loan‑to‑Value (LTV) Ratio Based on Property Value

Pag-IBIG applies different LTV ratios depending on the property’s appraised value. The economic housing limit is set at ₱2,499,999.99. The table below summarises the rules:

Appraised Value of Property	LTV Ratio (Maximum Loanable %)
Up to the economic housing limit	95%
Over the economic housing limit (up to ₱6,000,000)	90%

For example, a property valued at ₱1.5 million qualifies for a loan of up to 95% of that amount (₱1,425,000). A property at ₱3,000,000 would allow only 90% (₱2,700,000).

Calculating the Loanable Amount Based on Income

The general formula used by the calculator derives from the standard monthly amortisation equation combined with Pag-IBIG’s rule that the monthly amortisation (excluding insurance) must not exceed 35% of the borrower’s gross monthly income.

Let:

• $P$ = loanable amount (principal),
• $M$ = gross monthly income,
• $i$ = annual interest rate (as a decimal),
• $n$ = loan term in months.

First, the monthly amortisation $A$ (principal and interest only) from the general formula is:

$$A = P \cdot \dfrac{i/12 \cdot (1 + i/12)^{n}}{(1 + i/12)^{n} - 1}$$

Pag-IBIG’s capacity condition states:

$$A \leq 0.35 \cdot M$$

By combining these two equations and solving for $P$, we obtain the maximum loanable amount based on income:

$$P = \dfrac{0.35 \cdot M}{\dfrac{i/12 \cdot (1 + i/12)^{n}}{(1 + i/12)^{n} - 1}}$$

Similarly, the required monthly income for a given loan amount can be found by rearranging the same relationship:

$$M = \dfrac{A}{0.35}$$

Other Key Formulas Used in the Calculator

Monthly Principal and Interest (A)

As shown above, the tool uses the standard amortisation formula for $A$. This represents the portion of your monthly payment that goes toward paying down the principal and covering the interest. It does not include the insurance premium.

Monthly Insurance Premium (Q)

For Pag-IBIG housing loans, the monthly insurance premium is computed as:

$$Q = \dfrac{\text{Loan Amount} \times \text{Insurance Rate}}{12}$$

Where the Insurance Rate is a fixed percentage set by Pag-IBIG (the tool incorporates the current rate). The total monthly amortisation displayed is $A + Q$.

Estimated Equity

When you choose to “Show other calculated values”, the calculator displays the estimated equity required:

$$\text{Equity} = \text{Property Value} – \text{Loanable Amount}$$

This is the amount you must pay out of pocket (or from other sources) as a down payment.

Monthly Interest Allocation

The interest portion of each monthly payment is:

$$\text{Monthly Interest} = P \cdot \dfrac{i}{12}$$

Subtracting this from the total monthly principal‑and‑interest $A$ gives the monthly principal payment – the part that actually reduces the loan balance.

Example: Manual Calculation

Suppose you take a loan of ₱2,000,000 for 30 years ($n = 360$ months) at an annual rate of 9.75% ($i = 0.0975$).

1. Monthly amortisation (A):

   $$A = \dfrac{2000000 \times (0.0975/12) \times (1 + 0.0975/12)^{360}}{(1 + 0.0975/12)^{360} - 1} \approx ₱17,183.09$$

2. Monthly interest:

   $$\text{Monthly Interest} = 2000000 \times 0.0975 / 12 = ₱16,250.00$$

3. Monthly principal:

   $$\text{Monthly Principal} = ₱17,183.09 – ₱16,250.00 = ₱933.09$$

This illustrates that early in the loan term, only a small portion of the payment goes toward the principal.
