Why this matters
If you're shopping for a Security Bank home loan or trying to figure out whether your current mortgage rate still makes sense, a monthly amortization calculator is the fastest way to cut through the confusion. Security Bank currently offers some of the most competitive fixed rates in the Philippine market — their 5-year fixed rate of 6.75% p.a. and 1-year fixed rate of 6.99% p.a. are well below the 8–10% range that many Filipino homeowners are still paying on older loans. On a 3,000,000 peso loan over 20 years, the difference between 9.00% and 6.75% translates to thousands of pesos in monthly savings. You can explore the full breakdown of their offerings in our Security Bank housing loan interest rates guide.
Nook's calculator uses standard amortization math to give you an accurate estimate of your monthly payment at any rate and term combination. But a calculator is only the first step — the real value comes from knowing whether you qualify, how fast approval can happen, and what documents you'll need. Security Bank accepts borrowers across a wide range of employment types including private employees, government workers, OFWs, self-employed professionals, and freelancers, with a minimum monthly income requirement of 50,000 pesos and typical loan approval in around 23 days. For a complete picture of what to prepare, see our Security Bank housing loan requirements guide.
Whether you're computing a new purchase loan or checking if refinancing your existing mortgage makes financial sense, Nook connects you directly to Security Bank and other partner lenders — completely free. There are no broker fees, no hidden charges, and no obligation to proceed after you get your numbers. The best rate we've seen available through Nook right now is 5.99% p.a. — and the only way to know if you qualify is to run the numbers and apply. Interest rates are subject to change; always verify current rates directly with the bank or through Nook before making a financial decision.

Common questions
The calculator uses standard principal-and-interest amortization math, which is the same method banks use to compute monthly payments. It gives you a reliable estimate based on the loan amount, interest rate, and term you input. For the exact figure that will appear in your loan offer, you'll need to complete a formal application — bank fees, insurance premiums, and other charges may affect your total monthly obligation.
Security Bank currently offers a 1-year fixed rate of 6.99% p.a. and a 5-year fixed rate of 6.75% p.a. for home purchase and refinancing loans. Their Home Equity product carries a rate of 7.50% p.a. These rates are among the most competitive in the Philippine market, though they are subject to change — confirm the latest rates through Nook or directly with Security Bank before applying.

Security Bank requires a minimum monthly income of 50,000 pesos for home loan applicants. This applies across employment types including private employees, government workers, BPO employees, OFWs and seafarers, self-employed individuals, licensed professionals, and freelancers. Your debt-to-income ratio must also fall within 40% — meaning your total monthly loan obligations, including the new home loan payment, should not exceed 40% of your gross monthly income.
Yes, Nook's mortgage brokering service is 100% free to borrowers — there are no broker fees, application fees, or commissions charged to you at any stage of the process. Nook is compensated by partner banks only when a loan is successfully disbursed, which means your interest rate and loan terms are not affected by using the platform. You get the same bank rates with the added benefit of having a dedicated mortgage specialist guide your application.
