How this instrument works
The Pag-IBIG Fund — formally the Home Development Mutual Fund — is a Philippine government financial institution built from mandatory savings: most formally employed workers contribute 1-2% of pay each month, matched by their employer, and voluntary members and overseas Filipino workers can pay both shares themselves. The Housing Loan program lends that pooled savings back to members buying, building, or improving a home. Monthly amortization follows the same reducing-balance annuity formula any amortizing loan uses — level payments sized so that, at the stated rate, the final payment exactly zeroes the balance — because that is the only schedule that keeps interest tied strictly to what is still owed.
What separates this loan from a bank mortgage is the rate itself. Pag-IBIG publishes a tiered schedule where the interest rate climbs with the loan amount bracket, so a smaller loan aimed at a lower-income member carries a noticeably cheaper rate than a larger loan in the same program. That rate is also not fixed for the life of the loan the way a 30-year bank mortgage usually is: a borrower picks a repricing period — as short as one year or as long as the full term — and once it lapses, Pag-IBIG resets the rate to whatever its published tier charges at that later date and recomputes the remaining amortization against the new figure.
This sheet prices principal and interest only, treating the rate and term entered as if they held for the whole loan. It leaves out the mortgage redemption insurance premium and fire insurance premium Pag-IBIG requires on every housing loan, plus the appraisal, notarial, and registration charges collected at origination — all billed separately from the amortization shown here. It also assumes the full loan disburses at once rather than in the staged releases used for construction loans, where interest accrues only on amounts actually released.
- Enter the approved principal under Loan amount, ₱ — the sum Pag-IBIG released after your appraisal and contribution record cleared.
- Set Annual interest rate, % to the rate your loan bracket carries for its current repricing period, not a rate assumed to hold forever.
- Choose Loan term, years, up to the fund's 30-year maximum for qualifying members.
- Read Monthly amortization, ₱ for the fixed payment due each month until the next repricing date resets the rate.
Worked example — a ₱1,000,000 loan at the 6% tier
Take the sheet's own default: Loan amount, ₱ at 1,000,000, Annual interest rate, % at 6, and Loan term, years at 20 — a typical figure for a loan sitting in the fund's subsidized middle bracket. The monthly rate works out to i = 6 ÷ 1200 = 0.005, and the term runs N = 240 months. Feeding those three figures into the formula returns Monthly amortization, ₱ of 7,164.31, the fixed sum due every month for as long as this 6% rate holds.
Move only Annual interest rate, % to 10 — the rate a member borrowing the same ₱1,000,000 over the same 20 years would face without the subsidized tier — and Monthly amortization, ₱ rises to 9,650.22, close to ₱2,500 more every month for an identical loan. That gap is the concrete value of the fund's below-market tiers, and it is roughly the size of the jump a borrower would see the day a repricing period ends and the rate resets upward.
Questions
Why is the Pag-IBIG rate lower than a bank's mortgage rate?
Pag-IBIG lends from pooled mandatory member contributions rather than borrowing on open capital markets, so its cost of funds sits structurally below a commercial bank's. The fund also tiers its rate by loan amount, charging less on smaller loans aimed at lower-income members — the 6% used in the worked example sits in that subsidized range, well under typical bank mortgage rates for the same term.
Does the monthly amortization shown here stay fixed for the whole term?
Only until your chosen repricing period ends. Pag-IBIG lets a borrower fix the rate for one year or for periods running up to the full term; once a period expires, the fund resets the rate to its then-current published tier and recalculates the remaining payments against it. Monthly amortization, ₱ here is exact for the current period, not a lifetime guarantee.
Who is eligible for a Pag-IBIG Housing Loan?
An active Pag-IBIG member with at least 24 monthly savings contributions, or a lump-sum payment covering that gap, who is not in default on any other Pag-IBIG loan and fits within the fund's age-plus-term limit at maturity. Overseas Filipino workers qualify the same way, typically paying both the employee and employer contribution share themselves to build that 24-month record.
Is this the same as a Pag-IBIG Multi-Purpose Loan?
No. The Multi-Purpose Loan is a separate, short-term loan capped at a share of a member's accumulated savings, meant for emergencies, tuition, or minor repairs. The Housing Loan modeled here is secured by the property itself, runs up to 30 years, and finances buying, building, or improving an actual home — the two draw from the same fund but are underwritten completely differently.
What costs does this monthly amortization leave out?
Mortgage redemption insurance and fire insurance premiums, both required on every Pag-IBIG housing loan, plus one-time appraisal, notarial, and registration charges collected at origination. Those are billed on top of the amortization shown here, so a loan officer's total monthly collection will read higher than this sheet's Monthly amortization, ₱ figure alone.
Why might my actual Pag-IBIG amortization differ from this figure?
Small gaps usually trace to the approved loan amount differing from what was applied for after appraisal, or to your rate bracket boundary sitting slightly differently than assumed. Larger gaps often mean insurance premiums or a staged construction release schedule, where interest starts on each tranche only as it is released, were folded into the amount your loan officer quotes as the monthly due.
