Fixed vs Variable Interest Rates When Refinancing: What Every Filipino Homeowner Needs to Know

One of the most important decisions you will make when refinancing your home loan is choosing between a fixed or variable interest rate. Get it right and you could save hundreds of thousands of pesos over the life of your loan. Get it wrong and you could end up paying more than you need to — or worse, facing payment shock when rates rise unexpectedly.

This guide breaks down both options in plain language, with real numbers and practical examples tailored to the Philippine market.

How Fixed and Variable Rates Work in the Philippines

Before comparing the two, it helps to understand how Philippine banks actually structure their home loan rates — because it is slightly different from how rates work in the US or Australia.

Fixed Rates in the Philippine Context

In the Philippines, "fixed rate" almost never means fixed for the entire loan term. Instead, banks offer fixed-rate periods — typically 1, 2, 3, 5, or 10 years. After the fixed period ends, your rate reprices to whatever the bank's prevailing rate is at that time, usually based on market benchmarks plus a spread.

For example, you might refinance with Security Bank at a fixed rate of 5.99% p.a. for the first 3 years. In year 4, your rate reprices and could go up or down depending on market conditions at the time.

A true 20-year fixed rate is extremely rare in the Philippine market and is usually offered only by Pag-IBIG (HDMF) under specific programs.

Variable Rates in the Philippine Context

Variable rates (sometimes called floating rates) move with a reference rate — often the bank's own base lending rate or an external benchmark. Your monthly payment can change when the rate adjusts, which typically happens annually or quarterly depending on your loan agreement.

Variable rates are usually lower than fixed rates at any given moment because you are taking on the risk of rate movements. However, that lower starting rate comes with uncertainty.

A Side-by-Side Comparison

Here is a practical comparison using a loan of 4,000,000 pesos with a 20-year term — a common refinancing scenario in the Philippines.

Scenario A: 3-Year Fixed at 5.99% p.a.

Scenario B: Variable Rate Starting at 5.50% p.a.

The variable rate looks attractive at the start, but a 2-percentage-point rise — which has happened multiple times in Philippine banking history — erases those early savings quickly.

Which Rate Type Suits Your Situation?

There is no universally correct answer. The right choice depends on your financial profile, your plans for the property, and your tolerance for uncertainty. Here is a framework to help you decide.

The Repricing Cliff: What Most Borrowers Overlook

The most financially dangerous moment for any Philippine home loan borrower is the end of the fixed-rate period — what industry insiders call the repricing cliff.

Consider this real-world scenario: a homeowner took out a home loan in 2019 at a 5-year fixed rate of 6.25% p.a. In 2024, that fixed period ended. If the bank repriced the loan to a prevailing rate of 8.50% p.a., the monthly payment on a 3,500,000-peso outstanding balance over 15 remaining years would jump from approximately 30,100 pesos to approximately 34,450 pesos — an increase of 4,350 pesos per month or 52,200 pesos per year.

This is exactly the scenario where refinancing makes sense. By refinancing before or at repricing, you can lock in a new competitive rate — potentially as low as 5.99% p.a. through Nook — rather than accepting whatever your current bank offers as the repriced rate.

Use the refinance break-even calculator to find out how quickly the savings from a better rate cover any refinancing costs in your specific situation.

The Impact of Rate Differences on Total Cost

Many borrowers focus on the monthly payment difference and underestimate the total cost impact over a full loan term. Here is what different rate scenarios look like on a 5,000,000-peso loan over 20 years.

The difference between paying 5.99% and 8.50% on a 5,000,000-peso loan is approximately 1,821,000 pesos in total interest — nearly the cost of a small condominium unit. This is why your rate decision matters so much.

What Banks Are Currently Offering

As of 2025-2026, Philippine banks are offering a wide range of fixed-rate periods and rates for refinancing. Through Nook, the best available refinance rate is 5.99% p.a. for qualifying borrowers. Most homeowners who have not refinanced recently are paying rates between 7% and 10% — meaning the savings opportunity is significant for the majority of the market.

Different banks have different strengths. Some offer better rates for shorter fixed periods (1-2 years), while others are more competitive on 5-year fixes. The right bank for you depends on your loan amount, property location, employment type, and how long you want the rate locked in. This is exactly what a mortgage broker like Nook evaluates across multiple lenders simultaneously.

Hybrid Strategy: Using the Fixed Period Strategically

Sophisticated borrowers sometimes use a deliberate hybrid strategy. Rather than viewing the fixed period as a permanent commitment, they treat it as a window of certainty during which they aggressively pay down the principal.

For example: fix your rate at 5.99% for 3 years, and during those 3 years, make consistent extra payments toward the principal. By the time repricing arrives, your outstanding balance is significantly lower. Even if your rate rises at repricing, the smaller outstanding principal means the higher rate has less impact on your total interest cost.

Check the home loan prepayment calculator to see how much you can reduce your total interest by making additional payments during your fixed period.

Practical Steps Before Making Your Decision

  1. Find out your current rate and when it reprices. Call your bank or check your loan documents. Many homeowners do not know their rate is about to reprice.
  2. Calculate the total cost of each option. Do not just compare monthly payments. Compare total interest paid over the expected holding period.
  3. Model a stress test. Ask yourself: if rates rise 2 percentage points on a variable loan, can I still afford the payment? If not, a fixed rate is safer.
  4. Compare across multiple banks. Rates vary significantly between lenders. A broker like Nook compares across all major Philippine banks at no cost to you.
  5. Factor in switching costs. Refinancing involves processing fees, appraisal fees, and sometimes early settlement fees from your current bank. Make sure your interest savings outweigh these costs.
