YOUR POTENTIAL SAVINGS
No commitment. No credit check. Just your numbers.
Why this matters
If you have an existing Security Bank housing loan, the rate you're paying today may be significantly higher than what's currently available in the market. Many Filipino homeowners locked in rates between 8% and 10% in previous years and haven't revisited their mortgage since. With Security Bank's current fixed rates starting at 6.75% for a 5-year fix — and Nook's best available refinance rate at 5.99% p.a. — the difference can add up to hundreds of thousands of pesos over the remaining life of your loan. Use the calculator above to enter your specific loan amount, remaining term, and current rate to see exactly where you stand.
Security Bank is one of Nook's partner banks, offering competitive housing loan products with a 1-year fixed rate of 6.99% and a 5-year fixed rate of 6.75%. They accept a wide range of employment types including private employees, OFWs, self-employed professionals, and freelancers, with a minimum monthly income requirement of P50,000.

Common questions
Your monthly amortization is calculated using your loan amount, interest rate, and remaining loan term — this is a standard amortisation formula that spreads principal and interest equally across your payment period. For example, a P3,000,000 loan at 9.00% over 20 years results in a monthly payment of approximately P26,992. Use Nook's calculator above to input your actual figures and get an accurate estimate instantly.
