YOUR POTENTIAL MONTHLY SAVINGS
No commitment. No credit check. Just your numbers.
Why this matters
A property loan calculator gives you the power to see exactly what your monthly amortization will be before — or after — you sign anything. By entering your loan amount, interest rate, and remaining term, you can compute payments across BDO, BPI, Metrobank, Security Bank, PNB, and every other major Philippine bank side by side. Most Filipino homeowners currently carry rates between 7.50% and 10.00%, often locked in years ago when they had fewer options. Today, the gap between what you're paying and what's available can translate into thousands of pesos every single month. If you want a deeper look at where rates are heading, the latest Philippine home loan interest rate trends show a compelling case for acting sooner rather than later.
Refinancing is the most straightforward way to close that gap. When you refinance, a new lender pays off your existing loan and issues a replacement at a lower rate — your monthly amortization drops immediately, and the savings compound over the remaining life of your loan. On a 3,000,000 peso loan with 20 years remaining, moving from 8.50% down to Nook's best available rate of 5.99% reduces your monthly payment by over 3,800 pesos. Over the full term that adds up to nearly 700,000 pesos kept in your pocket instead of paid to a bank. You can model your own numbers instantly using Nook's home loan refinance savings calculator to see your personalised figure.

Common questions
To calculate your monthly amortization, you need three inputs: your loan amount (principal), your annual interest rate, and your loan term in months. The standard formula uses these to produce a fixed monthly payment that covers both interest and principal reduction — and you can do this instantly using Nook's free online calculator without any manual math.
Rates vary by bank, loan amount, property type, and borrower profile, but competitive offers in 2026 typically range from 5.99% to 7.50% p.a. for the initial fixed-rate period. BPI, Security Bank, BDO, and Metrobank are frequently among the most competitive, but the only way to know your best available rate is to compare multiple lenders at the same time — which is exactly what Nook does for you at no cost.
A fixed rate locks your interest rate — and therefore your monthly payment — for a set period, commonly 1, 3, or 5 years, giving you predictability and protection from rate increases. A variable rate can move up or down after the fixing period ends, which means your amortization may change. Most Philippine banks reprice your loan at the end of every fixed period, which is also when refinancing to a better deal makes the most financial sense.
The savings depend on how far your current rate is above today's best available rate and how much principal remains on your loan. On a 3,000,000 peso balance with 20 years remaining, dropping from 8.50% to 5.99% saves over 3,800 pesos per month and nearly 700,000 pesos over the life of the loan. Even a 1.50 percentage point reduction on a smaller balance can still save hundreds of thousands of pesos in total interest.
Yes, refinancing typically involves closing costs such as appraisal fees, documentary stamp tax, registration fees, and a potential prepayment penalty from your existing lender — but in most cases these are significantly outweighed by the long-term interest savings.
