Why this matters
A home loan amortization calculator breaks down every monthly payment into its two components: the portion that reduces your principal balance, and the portion that goes to interest. In the early years of a Philippine home loan, the vast majority of each payment is pure interest — which is why your outstanding balance barely moves in the first five years. Understanding this is the first step to realizing just how expensive a high interest rate truly is over a 20-year term.
Most Filipino homeowners with loans from BDO, BPI, Metrobank, Security Bank, or other local banks re-price their interest rate every three to five years. If you signed your loan a few years ago at 8% to 9%, there's a strong chance you're now overpaying relative to what the market offers today. By entering your current loan balance, remaining term, and existing rate into an amortization calculator, you can immediately see how a rate reduction to as low as 5.99% p.a. — available through Nook — changes your monthly obligation. You can also use the home loan refinance calculator to model the full savings picture, including how quickly you recover any switching costs.
Before you decide to refinance, it helps to understand what documents and equity levels Philippine banks require. Check out the home loan refinance requirements guide so you know exactly what to prepare. Nook's service is completely free to borrowers — we're paid by the bank, not by you — so there's no cost to running the numbers and finding out whether a lower rate makes sense for your situation.

Common questions
A home loan amortization calculator computes your fixed monthly payment based on your loan amount, interest rate, and remaining term. It also generates a full schedule showing how much of each payment goes to principal versus interest — this is called the amortization table. In the Philippines, most home loans use a monthly rest calculation, which is what standard amortization calculators apply.
On a 3,000,000 loan over 20 years, your monthly payment depends entirely on your interest rate. At 8.50% you would pay roughly 26,035 per month, while at Nook's best available rate of 5.99% the same loan would cost approximately 22,966 per month — a difference of over 3,000 every single month. That gap compounds significantly over a 20-year term.
Yes — by entering the same loan amount and term with different interest rates, you can directly compare what each bank's offer would cost you monthly. Philippine banks including BDO, BPI, Metrobank, Security Bank, and RCBC all offer home loan refinancing with varying rates. Nook shops all of these lenders simultaneously so you can see the best available rate in one place without filing multiple applications.
Amortization refers to the scheduled repayment of your loan over time through regular monthly payments. Refinancing is the process of replacing your existing loan with a new one — ideally at a lower interest rate — which then generates a new amortization schedule. Refinancing doesn't erase your debt, but it can significantly reduce your monthly payment and the total interest you pay over the life of the loan.
Yes, refinancing typically involves fees such as appraisal costs, documentary stamp tax, notarial fees, and sometimes a prepayment penalty from your current bank. However, for most borrowers the monthly savings far outweigh these one-time costs within the first one to two years. Nook's service is 100% free to borrowers, and our team can help you calculate the exact break-even point for your specific loan.
