Your Pag-IBIG housing loan’s monthly amortization comes down to three numbers you know before you even apply — the loan amount, the interest rate bracket it falls into, and the repayment term — and you can estimate it yourself, within a few pesos, using the same reducing-balance formula Pag-IBIG applies. Pag-IBIG Fund does not publish a public online amortization calculator; the only official figure comes from a loan officer’s computation once you apply through a branch or Virtual Pag-IBIG. This guide gives you the actual formula, a ready-made factor table for every current rate bracket and term, and a worked example, so you can size up a loan before committing to a reservation fee or contract to sell. For eligibility, documentary requirements, and the full application process, see our companion Pag-IBIG Housing Loan guide.
Decision Snapshot
- What it is: Monthly amortization is the fixed peso amount you pay Pag-IBIG each month toward principal and interest on a housing loan, computed using a standard reducing-balance formula over your chosen term.
- Where to get the official number: Only Pag-IBIG’s own computation at application — through a branch or the Virtual Pag-IBIG portal — is authoritative; there is no official public calculator, so treat any self-computed figure, including the ones in this guide, as an estimate.
- The key qualifying detail: Your rate depends on which bracket your loan amount falls into — socialized housing tops out at ₱950,000 for house-and-lot or ₱1.8 million for a condominium unit; anything above that moves into the low-cost or regular bracket at a higher rate.
- Current 2026 promo rates: 3% per year for qualified socialized housing borrowers, 4.5% for the low-cost bracket, and 5.75% for the regular bracket up to the ₱10 million ceiling — each fixed only for an initial period (Inquirer Business; Philippine Information Agency).
- An important caveat: These promotional rates apply only to applications filed by December 31, 2026, and every bracket reprices after its fixed period under Pag-IBIG’s Full Risk-Based Pricing Framework — your amortization can change even if you never miss a payment.
- Next step: Use the factor table below to get a working estimate for your own loan amount, term, and bracket, then have Pag-IBIG confirm the exact figure — including Mortgage Redemption Insurance and fire insurance add-ons — before you sign anything.
What Actually Determines Your Monthly Amortization
Three inputs decide your Pag-IBIG monthly amortization, and all three are things you choose or already know before you file an application:
- Loan amount — the principal you actually borrow, which is the lowest of what you asked for, the property’s appraised value under Pag-IBIG’s loan-to-value limits, and your income-based qualifying capacity.
- Interest rate bracket — set by where your loan amount lands relative to the socialized, low-cost, and regular housing thresholds (see the table below), not by your credit history the way a bank loan would be priced.
- Repayment term — up to 30 years, but capped so the loan matures before you turn 70 (Pag-IBIG Fund Affordable Housing Program guidelines, Circular No. 403, Supreme Court E-Library). A longer term lowers your monthly amortization but increases total interest paid over the life of the loan.
Pag-IBIG also caps how much you can borrow relative to your income. Under the Affordable Housing Program guidelines, the loanable amount is limited so that monthly amortization does not exceed 35% of the borrower’s gross monthly income (Section 4.2.2, Circular No. 403, Supreme Court E-Library); some lender-facing references instead describe a 40%-of-net-disposable-income limit for the Regular Housing Loan. The two figures come from different guidelines and can both be in circulation depending on which program you apply under, so treat either percentage as approximate and ask your handling branch which affordability cap applies to your specific loan before you assume a maximum loan amount.
Current Pag-IBIG Housing Loan Rate Brackets (2026)
Pag-IBIG prices a housing loan by bracket, not by individual credit risk. As of this writing, the promotional structure introduced under the Fund’s expanded affordable housing push is:
| Bracket | Loan amount covered | Promo rate | Fixed for |
|---|---|---|---|
| Socialized housing (4PH) | Up to ₱950,000 (house-and-lot) / ₱1.8 million (condo), income-qualified | 3.0% per year (as low as 1% with additional government subsidy for qualified borrowers) | First 5 years; Early Bird promo gives the first 30,000 qualified borrowers 3% for 10 years |
| Low-cost housing | Above the socialized ceiling up to ₱2.5 million | 4.5% per year | 3 years |
| Regular housing | Above ₱2.5 million up to ₱10 million (loan ceiling) | 5.75% per year | 3 years |
Sources: Philippine Information Agency and Inquirer Business, reporting Pag-IBIG’s 2026 promotional rate cuts. These promo rates apply to applications filed through December 31, 2026; after that, or after each bracket’s fixed period ends, pricing reverts to Pag-IBIG’s standard Full Risk-Based Pricing Framework, which can be higher. Confirm the rate in effect on your application date directly with Pag-IBIG, since promotional programs are periodically extended, revised, or allowed to lapse.
How Amortization Is Actually Calculated
Pag-IBIG, like virtually every Philippine housing lender, computes monthly amortization using the standard reducing-balance (amortizing) loan formula. Each payment is split between interest on the remaining balance and a reduction of principal, with the split shifting toward principal as the loan matures. The formula is:
M = P × [ i × (1 + i)n ] ÷ [ (1 + i)n − 1 ]
- M = your monthly amortization (principal and interest only)
- P = the loan principal (amount borrowed)
- i = the monthly interest rate (your annual rate ÷ 12)
- n = the total number of monthly payments (your term in years × 12)
This is the general amortizing-loan formula used across mortgage lending worldwide (see, for reference, the mechanics described in Wikipedia’s overview of amortization calculation) and it is what produces the government-published example figures Pag-IBIG and news outlets cite for its 2026 promo rates. You rarely need to run this formula by hand, though — the factor table below already does the math for every current rate and common term.
Amortization Factor Table: Estimate Your Payment Per ₱100,000 Borrowed
The table below shows the monthly amortization for every ₱100,000 you borrow, at each current Pag-IBIG promo rate, across common terms. To estimate your own payment, divide your loan amount by 100,000, then multiply by the matching factor.
| Rate | 10 years | 15 years | 20 years | 25 years | 30 years |
|---|---|---|---|---|---|
| 3.00% (socialized) | ₱966 | ₱691 | ₱555 | ₱474 | ₱422 |
| 4.50% (low-cost) | ₱1,036 | ₱765 | ₱633 | ₱556 | ₱507 |
| 5.75% (regular) | ₱1,098 | ₱830 | ₱702 | ₱629 | ₱584 |
These factors are computed directly from the reducing-balance formula above and check out against the government-cited examples for the current promo: a ₱2.5 million loan at 4.5% over 30 years works out to roughly ₱12,675 using this table (₱507 × 25), matching the approximately ₱12,667 that Pag-IBIG’s own 2026 announcement cites for that scenario (Inquirer Business). Small rounding differences between this table and Pag-IBIG’s official computation are normal and do not indicate an error in either figure.
How to Estimate Your Own Monthly Amortization
- Confirm your loan amount. Use the actual amount you plan to borrow, not the property’s full price — subtract any down payment or equity you’ll pay directly to the seller or developer.
- Identify your rate bracket. Compare your loan amount against the socialized, low-cost, and regular thresholds in the rate table above.
- Choose a term. Remember it cannot extend past your 70th birthday, and a longer term lowers your monthly payment but raises total interest paid.
- Find the matching factor in the amortization factor table for your rate and term.
- Multiply. Divide your loan amount by 100,000, then multiply by the factor to get your estimated principal-and-interest amortization.
- Add Mortgage Redemption Insurance and fire insurance. These are usually bundled into your total monthly billing on top of principal and interest — see our guide to Mortgage Redemption Insurance for how that premium is computed.
- Confirm with Pag-IBIG. Treat the result as a planning estimate only, and have your branch or loan officer run the official computation before you commit to a reservation fee or sign a contract to sell.
Worked Example: Estimating a Loan on a Mid-Priced House-and-Lot
The figures below are a hypothetical illustration only — not a real borrower, not a guaranteed rate, and not a substitute for Pag-IBIG’s own computation at the time you apply.
- Scenario: A member needs to borrow ₱1,500,000 for a house-and-lot unit. Since this exceeds the ₱950,000 socialized ceiling for house-and-lot, it falls into the low-cost bracket at the 2026 promo rate of 4.5%, fixed for 3 years.
- Step 1: ₱1,500,000 ÷ 100,000 = 15 units of ₱100,000.
- Step 2 — over a 20-year term: 15 × ₱633 = approximately ₱9,495 per month in principal and interest.
- Step 3 — compare a 30-year term: 15 × ₱507 = approximately ₱7,605 per month — about ₱1,890 less, but roughly 10 more years of payments and materially more total interest over the life of the loan.
- What this doesn’t include: Mortgage Redemption Insurance, fire insurance, and any processing or appraisal fees financed into the loan, all of which raise the actual amount billed each month above the principal-and-interest figure above.
- What changes later: This 4.5% rate is fixed for only 3 years. When it reprices, the new rate follows Pag-IBIG’s prevailing Full Risk-Based Pricing at that time, and the monthly amortization is recalculated on the remaining balance and remaining term — it can go up or down.
Rate vs. Amortization Factor vs. Total Monthly Payment
Borrowers frequently mix these terms up when comparing loan offers or reading promotional material. Here’s the practical distinction:
| Term | What it means | Where it appears |
|---|---|---|
| Interest rate | The annual percentage charged on the outstanding balance — the input to the amortization formula, not a monthly figure | Advertised in Pag-IBIG promos (e.g., “4.5% per annum”) |
| Amortization factor | A shortcut figure (like the ones in this guide) showing the monthly payment per ₱100,000 borrowed at a given rate and term | Used to estimate a payment quickly without recomputing the formula each time |
| Monthly amortization | Your actual monthly principal-and-interest payment for your specific loan amount, rate, and term | What Pag-IBIG bills you as the base loan payment |
| Total monthly payment | Monthly amortization plus Mortgage Redemption Insurance, fire insurance, and any other add-ons billed with the loan | The actual amount that leaves your account each due date |
What to Verify Before You Rely on This
- Your actual approved loan amount, which can be lower than what you requested once Pag-IBIG applies its appraisal and income-based limits.
- The rate bracket and promo status in effect on your application date, since promotional pricing has a stated cutoff and can be extended, revised, or withdrawn.
- Which affordability cap applies to your loan — the percentage of income used to limit your loanable amount differs across Pag-IBIG guidelines, so confirm the applicable figure with your branch rather than assuming one.
- Mortgage Redemption Insurance and fire insurance premiums, which are not included in the factor table and add to your actual monthly billing.
- Your repricing terms — ask what rate applies once your fixed period ends and how far in advance Pag-IBIG notifies you of a repriced amortization.
- Any processing, appraisal, or registration fees that may be deducted from loan proceeds or added to the amount financed, which changes the effective principal you’re actually amortizing.
Frequently Asked Questions
Does Pag-IBIG have an official online amortization calculator?
Not a standalone public calculator as of this writing. The Virtual Pag-IBIG portal handles loan applications and account management, but the binding computation of your amortization comes from your loan officer once you apply, using your approved loan amount, bracket, and term.
Why does my estimate differ slightly from Pag-IBIG’s official computation?
Small differences usually come from rounding in the factor table, from Pag-IBIG using a slightly different day-count or effective-rate convention internally, or from add-ons like Mortgage Redemption Insurance and fire insurance being folded into their quoted “monthly payment” but not into a pure principal-and-interest estimate.
Can I lower my monthly amortization after the loan is approved?
Generally only by making a lump-sum payment toward principal (which reduces the balance the formula runs on) or, where Pag-IBIG allows it, restructuring the remaining term. Changing brackets or rates outside of scheduled repricing is not something a borrower can request on demand.
What happens to my amortization when the fixed-rate period ends?
Your loan reprices to the rate Pag-IBIG is then offering under its Full Risk-Based Pricing Framework for your chosen repricing option, and your amortization is recalculated on the remaining balance and remaining term. It can increase or decrease depending on prevailing rates at that time.
Does a longer term always mean I pay more overall?
Yes, for the same principal and rate, a longer term lowers your monthly amortization but increases the total interest you pay over the life of the loan, since more of each early payment goes to interest on a balance that takes longer to shrink.
Is the factor table in this guide the same for a bank housing loan?
The reducing-balance formula is the same, but banks price loans individually based on credit risk rather than Pag-IBIG’s fixed brackets, so you’d need to apply the formula with the bank’s quoted rate. See our Bank Housing Loan guide for how that process differs.
Does the factor table account for Mortgage Redemption Insurance?
No. The table estimates principal-and-interest amortization only. Mortgage Redemption Insurance and fire insurance are typically billed on top of that base figure, so your actual total monthly payment will be somewhat higher than the factor table alone suggests.
What to Do Next
Use the amortization factor table above to get a realistic monthly-payment range for the loan amount and term you’re considering, and run the numbers for at least two terms so you can see the trade-off between a lower monthly amortization and total interest paid. Once you have a working estimate, bring it to a Pag-IBIG branch or apply through Virtual Pag-IBIG so a loan officer can confirm your actual bracket, rate, and add-ons before you commit to a reservation fee or sign a contract to sell.
Figures in this article reflect Pag-IBIG’s published 2026 promotional housing loan rates (3% socialized, 4.5% low-cost, 5.75% regular) as reported by the Philippine Information Agency and Inquirer Business, and structural terms (30-year maximum term, income-based affordability limits) from Pag-IBIG Fund Circular No. 403. Promotional rates, income thresholds, and affordability limits can change or be revised, and this guide’s factor table is a planning estimate, not an official computation. Confirm your actual rate, bracket, and monthly amortization with Pag-IBIG Fund directly before applying for or accepting a housing loan.
