Why this matters
A house mortgage calculator helps you estimate your monthly amortization based on three inputs: your outstanding loan amount, your interest rate, and your remaining loan term. In the Philippines, most bank home loans are repriced every 1, 3, or 5 years — which means the rate you started with is almost certainly not the rate you're paying today. Many homeowners are surprised to discover they've drifted into the 8% to 10% range without realising it, simply because they never shopped around at repricing time. Running the numbers through a calculator is the first step to understanding whether your current bank is still giving you a fair deal.
Once you know your current monthly payment, the next question is: what would it look like at a lower rate? At 5.99% p.a. on a 3,000,000 loan over 20 years, your monthly repayment drops significantly compared to 8.50% — a difference of over 4,000 pesos every single month. That's real money that could go toward your children's education, emergency savings, or paying down your principal faster. If you want to go deeper on the numbers, Nook's home loan refinance calculator lets you model your exact loan details and see a personalised savings estimate in seconds.
Refinancing in the Philippines is more accessible than most homeowners think, and Nook's service is completely free to borrowers — Nook is paid by the bank, not by you. The process involves submitting your documents once, and Nook handles the comparison and application across multiple lenders on your behalf. Before you start, it's worth reviewing the home loan refinance requirements in the Philippines so you know exactly what to prepare. Most approvals take two to four weeks, and switching lenders could save you hundreds of thousands of pesos over the life of your loan.

Common questions
A mortgage calculator uses the standard amortisation formula to spread your loan balance across equal monthly payments over your chosen term. You input three things — loan amount, interest rate, and loan term in years — and the calculator tells you your monthly amortization. In the Philippines, most home loans are quoted as annual interest rates, so the calculator divides that rate by 12 to compute each month's interest portion versus principal repayment.
Use the rate currently stated in your latest bank statement or loan repricing notice — not the rate you signed up with years ago. Philippine bank home loans are typically repriced every 1 to 5 years, so your current rate may be higher than you expect. If you're not sure, call your bank and ask for your current effective interest rate per annum.
In 2025 and into 2026, competitive home loan rates in the Philippines range from about 6% to 8% p.a. for fixed periods of 1 to 5 years. Through Nook, the best available refinance rate is currently 5.99% p.a., which is among the lowest on the market. Anything above 8.5% is worth reviewing, especially if your loan balance is still above 1,500,000 pesos.
Yes — refinancing means moving your outstanding home loan balance to a new lender (or renegotiating terms with your existing one) in order to secure a lower interest rate. It's one of the most effective ways to reduce your monthly amortization without shortening your lifestyle. Nook makes this process free and straightforward for Filipino borrowers, handling bank comparisons and paperwork on your behalf.
There are some upfront costs to refinancing, including appraisal fees, notarial fees, and mortgage registration charges — typically totalling between 1% and 2% of the loan amount. However, for most borrowers these are recovered within 12 to 18 months through monthly savings. For a full breakdown, see Nook's guide to home loan refinance closing costs in the Philippines.
