Variable vs Fixed Rate Mortgages Philippines - Which Should You Choose?

A fixed rate mortgage locks your interest rate in at a set percentage for a defined period — typically 1, 2, 3, 5, or 10 years, depending on the bank. During that fixed period, your monthly amortisation stays exactly the same regardless of what happens to market interest rates in the broader economy.

For example, if you take a 5,000,000 home loan at a fixed rate of 6.75% p.a. for 3 years on a 20-year term, your monthly repayment during those 3 years will be exactly 37,867. It won't move — even if the Bangko Sentral ng Pilipinas (BSP) raises benchmark rates by 1% or more during that time.

After the fixed period ends, most Philippine banks reprice your loan to whatever their prevailing rate is at that time. This is sometimes called a "re-pricing date" and it's one of the most important events in your mortgage lifecycle — it's often when homeowners discover they're suddenly paying far more than they need to, and when refinancing makes the most sense.

A variable rate mortgage (also called a floating rate mortgage) has an interest rate that can change over time, typically linked to a benchmark rate or reviewed periodically by your bank. In the Philippines, variable rates are usually tied to a bank's own "prevailing lending rate" or benchmarked against treasury bill rates or the Philippine Interbank Reference Rate (PHIBOR).

When market rates rise, your variable rate goes up — meaning your monthly repayments increase. When market rates fall, your rate should drop too, reducing your monthly payments. In practice, however, many Filipino borrowers have found that Philippine banks are quicker to pass on rate increases than rate decreases.

Variable rate products sometimes start with a lower introductory rate than comparable fixed rate products, which can be attractive upfront. But the unpredictability makes budgeting harder, especially for households with tight monthly cash flows. If you want to model how different rate scenarios affect your total repayments, our home loan refinance calculator lets you compare different rate assumptions side by side.

Here's a straightforward comparison of the two rate types across the factors that matter most to Filipino homeowners:

• Repayment certainty: Fixed gives you a guaranteed monthly payment for the lock-in period. Variable can change at any time, making it harder to budget.
• Starting rate: Variable rates sometimes start slightly lower than fixed rates for the same loan, though this gap has narrowed in recent years.
• Risk exposure: With variable, you carry the risk of rate increases. With fixed, the bank carries that risk during the lock-in period — which is why fixed rates are often priced slightly higher.
• Flexibility: Variable rate loans often have fewer (or no) pre-termination penalties during the floating period. Fixed rate loans may charge a penalty if you refinance or fully pay within the lock-in window.
• Long-term cost: This depends heavily on where interest rates go. In a falling rate environment, variable wins. In a rising or stable rate environment, fixed often wins or at least protects you.
• Refinancing timing: The end of a fixed period is the ideal time to refinance without penalties — a key consideration when planning your strategy.

There's no single correct answer — it depends on the rate environment over your loan term. But here's a concrete illustration using a 5,000,000 loan on a 20-year term to show how the difference plays out:

Scenario A — Fixed at 6.50% for the full term: Monthly repayment of 37,253. Total interest paid over 20 years: approximately 3,940,720.

Scenario B — Variable starting at 6.00%, rising to 8.50% after 3 years: Monthly repayment starts at 35,822, then jumps to 42,603 after repricing. Total interest paid over 20 years: approximately 4,650,000+ depending on subsequent rate movements.

The key insight is that a low starting variable rate can easily be wiped out — and then some — by a single repricing event. This is exactly the experience many Filipino homeowners had after the BSP raised rates aggressively in 2022–2023. Borrowers on variable rates saw their monthly repayments jump by 5,000 to 15,000 almost overnight.

On the other hand, if you have a variable rate loan and rates fall significantly, you benefit automatically without needing to refinance. The honest answer is: if you can secure a competitive fixed rate now (like the 5.99% p.a. currently available through Nook), locking in certainty is often the smarter financial decision for most households.

This is one of the most financially consequential moments in your mortgage — and one that many homeowners are caught off guard by. When your fixed rate period ends (your "re-pricing date"), your bank will reprice your loan to their current prevailing rate. In most cases, this new rate is significantly higher than your original fixed rate.

For example, a homeowner who locked in at 5.50% fixed for 3 years back in 2021 might find themselves repriced to 8.50% or higher in 2024. On a remaining loan balance of 4,000,000 with 17 years left, that rate jump increases monthly repayments from approximately 27,372 to approximately 35,191 — an increase of 7,819 per month, or 93,828 per year.

You have three options at this point: (1) accept the new rate and continue paying more, (2) negotiate with your existing bank for a better rate, or (3) refinance to a different bank offering a lower rate. Option 3 — refinancing through a broker like Nook — almost always produces the best result, because you're putting multiple banks in competition for your loan. The re-pricing date is also the safest time to refinance because most lock-in penalty clauses expire at this point.

The 5.99% p.a. rate currently available through Nook is a fixed rate for an initial lock-in period (typically 1 to 5 years depending on the bank and loan structure). This means your monthly repayment is guaranteed to stay the same for the duration of that fixed period — giving you both savings and certainty.

To put that in perspective: if you're currently paying 8.50% on a 4,000,000 outstanding balance with 15 years remaining, refinancing to 5.99% would reduce your monthly repayment from approximately 39,401 to approximately 33,724 — a saving of 5,677 per month, or 68,124 per year. Over the full 15-year term, that's more than 1,000,000 in total interest savings.

Because rates and product availability vary by bank and loan profile, the Nook team will match you with the specific bank and rate structure that makes the most sense for your situation — whether that's a 1-year fixed, 3-year fixed, or another arrangement. The service is completely free to you as the borrower.

Yes — and for many homeowners currently on a variable rate, now is an excellent time to consider doing exactly that. You have two main paths:

Option 1 — Ask your existing bank to reprice or restructure: Some Philippine banks will allow you to convert your variable rate loan to a fixed rate product, though they're not obligated to match the market's best rates. The rate they offer you as an existing customer is rarely as competitive as what you'd get as a new borrower at a competing bank.

Option 2 — Refinance to a new bank through Nook: This is almost always the more effective route. By refinancing, you're effectively taking out a new loan at a new bank at the current best available rate. The competitive pressure of multiple banks bidding for your loan means you're far more likely to secure a rate like 5.99% p.a. fixed than by staying with your current lender.

If you're currently on a variable rate and feeling the pinch of recent rate increases, use our refinance break-even calculator to see how quickly the savings from switching to a fixed rate would offset any refinancing costs.

Philippine banks price mortgage rates based on several factors, and the fixed vs variable distinction affects pricing in predictable ways:

For fixed rates: Banks price in a "certainty premium" — they're taking on the risk that market rates might rise during your lock-in period, so they charge slightly more than they would for a variable product. The longer the fixed period, the higher this premium tends to be. A 5-year fixed rate will typically be priced higher than a 1-year fixed rate from the same bank.

For variable rates: Banks typically benchmark to a reference rate — often tied to treasury bill yields or the BSP's overnight reverse repurchase (RRP) rate — and add a spread. When the BSP raises rates, your variable rate follows. When the BSP cuts rates, your rate should fall too (though the pass-through isn't always immediate or equal).

Major Philippine banks like BDO, BPI, Metrobank, Security Bank, RCBC, and UnionBank all offer both fixed and variable products, but their pricing and terms vary significantly. This is precisely why using a broker like Nook — which compares rates across multiple banks simultaneously — is so valuable. What looks like a small difference in rate (say 0.50%) translates to hundreds of thousands of pesos over a 15–20 year loan term.

For most homeowners refinancing in the current environment, a fixed rate is generally the smarter choice — for three main reasons:

1. Rate certainty maximises your savings window. When you refinance, you're locking in a lower rate than what you're currently paying. A fixed rate guarantees that saving for the duration of the lock-in period. A variable rate could erode those savings if rates rise again.

2. The current rate environment favours locking in. With the best available refinance rate sitting at 5.99% p.a. — historically quite competitive by Philippine standards — fixing in now protects you if rates move back up.

3. Most refinancing costs are upfront. Since refinancing involves some upfront costs (processing fees, documentary stamps, etc.), you want to maximise the period over which you benefit from the lower rate. A fixed rate gives you a defined, guaranteed savings window to recoup those costs and then profit from the lower rate.

That said, if you expect to sell the property or fully settle the loan within 1–2 years, and a variable rate is being offered at a meaningful discount, the calculus changes. Your Nook broker will walk through your specific scenario and help you model both options before making a recommendation.

Use these five questions to guide your decision:

1. How long do you plan to keep this property? If you're planning to sell within 2–3 years, the shorter your investment horizon, the less the rate type matters for long-term savings. If you're staying long-term, the compounding effect of rate differences is significant.
2. How sensitive is your monthly budget to payment increases? If an unexpected jump of 5,000–10,000 per month would cause genuine financial stress, fixed rate is the safer choice — full stop.
3. What's your view on interest rate direction? If you believe rates are likely to fall significantly in the near term, a variable rate lets you benefit automatically. If you think rates will stay flat or rise, fixed protects you.
4. What's your re-pricing date? If your current fixed period ends within the next 6–12 months, you should be looking at refinancing options now — regardless of which rate type you ultimately choose.
5. What's the actual rate difference between fixed and variable offers? If the gap is small (say, 0.25% or less), the certainty of fixed is usually worth the marginal difference. If variable is being offered at a significant discount of 0.75% or more, the calculus gets more complex.

The simplest approach: talk to a Nook broker. We'll compare live rates from multiple Philippine banks, run the numbers for your specific loan balance and remaining term, and give you a clear, unbiased recommendation — at no cost to you.
