Why this matters
A BDO housing loan is one of the most popular home financing options in the Philippines, thanks to BDO's wide branch network and flexible loan structures. As a Nook partner bank, BDO offers a 1-Year Fixed rate of 6.00% p.a. — one of the most competitive rates available for refinancing in 2026. Whether you're computing a new purchase loan or estimating what refinancing your existing mortgage could save you, understanding how your monthly amortization is calculated is the first step toward making a smarter financial decision. You can also review the full BDO home loan interest rates and refinancing guide to see how rates have moved and what to expect.
Monthly amortization is calculated based on three key inputs: your loan amount, your interest rate, and your remaining loan term. On a 3,000,000 loan over 20 years, a borrower currently paying 8.50% p.a. would have a monthly payment of approximately 26,035. By refinancing through Nook to a rate of 5.99% p.a., that same borrower could reduce their payment to around 22,966 — a saving of over 3,000 every month. Over the life of the loan, that adds up to more than 550,000 in total interest savings. Salary also plays a role: BDO requires a minimum monthly income of 50,000, and your debt-to-income ratio must not exceed 40%, meaning your total monthly debt obligations should be no more than 40% of your gross monthly income.
Nook's service is completely free for borrowers. We work directly with BDO and other leading Philippine banks to find you the best available rate based on your profile — without charging broker fees or commissions. If you want to understand what documents and qualifications are needed before you apply, the BDO housing loan requirements guide covers everything from employment types to acceptable collateral. Once you're ready, Nook can help you submit a single application and compare offers across multiple banks simultaneously. Please note that interest rates are subject to change — always verify the current applicable rate with BDO or through Nook before making any financial decisions.

Common questions
Your monthly amortization is determined by three factors: your loan amount, the applicable interest rate, and your loan term. For example, a 3,000,000 loan at 8.50% p.a. over 20 years results in a monthly payment of approximately 26,035. Using a standard amortization formula, a larger loan amount, higher rate, or shorter term will each increase your monthly payment.
BDO requires a minimum monthly income of 50,000 for housing loan applicants. Your total monthly debt obligations — including your new housing loan amortization — must not exceed 40% of your gross monthly income, which is BDO's maximum debt-to-income ratio. BDO accepts income from private employment, government service, BPO, OFW/seafarer remittances, self-employment, and professional practice.
As a Nook partner bank, BDO currently offers a 1-Year Fixed rate of 6.00% p.a. for housing loans including refinancing. Rates are subject to repricing after the fixed period ends, so it's important to understand the full rate schedule before committing. Always confirm the latest applicable rate directly with BDO or through Nook, as rates can change without prior notice.
Yes — refinancing to BDO is one of the most common transactions Nook facilitates for Filipino homeowners. If you're currently paying a rate above 6.00% with any bank, switching to BDO through Nook could meaningfully reduce your monthly payment. Nook's refinancing service is 100% free to borrowers, and the typical BDO approval timeline is around 30 days.
Savings depend on your current rate, loan balance, and remaining term. On a 3,000,000 loan with 20 years remaining, moving from 8.50% to 5.99% p.a. saves approximately 3,069 per month — or over 36,000 per year. Over the full loan term, that represents a total saving of more than 550,000 in interest payments that stay in your pocket instead of going to the bank.
