Why this matters
Security Bank is one of the Philippines' most competitive home loan providers, offering fixed-rate periods starting from 1 year at 6.99% p.a. up to 5 years at 7.75% p.a. These rates are among the sharper offerings in the market — but if you took out your loan a few years ago, your current repriced rate may be significantly higher. Many Filipino homeowners are quietly paying 8%, 9%, or even 10% on loans they've never reviewed. A quick calculation can reveal whether you're leaving real money on the table every single month. Before you fill out a Security Bank home loan application form, it's worth running the numbers to understand exactly what rate and term work best for your situation.
Our calculator uses standard amortization methodology — the same formula Philippine banks apply — so you can trust the estimates as a reliable starting point. Simply enter your outstanding loan balance, remaining term, and current interest rate to see your monthly payment. Then compare it against Nook's best available refinance rate of 5.99% p.a. to understand your potential savings. For a ₱3,000,000 loan on a 20-year term, the difference between 8.50% and 5.99% translates to over ₱3,000 saved every month — that's more than ₱36,000 a year staying in your pocket instead of going to the bank.
Refinancing through Nook is completely free to borrowers. We work with Security Bank and other leading Philippine lenders to find you the most competitive rate for your profile — handling the comparison, paperwork coordination, and follow-up on your behalf.

Common questions
Our calculator uses the standard reducing-balance amortization formula applied by Philippine banks, so results are a reliable estimate of your monthly payment given the inputs you provide. Keep in mind that your actual amortization may vary slightly depending on your loan's specific terms, fees, and repricing schedule. We recommend using this as a planning tool and confirming exact figures with Security Bank or a Nook mortgage advisor.
As of 2025, Security Bank offers a 1-year fixed rate of 6.99% p.a., a 3-year fixed rate of 7.25% p.a., and a 5-year fixed rate of 7.75% p.a. After your fixed period ends, your loan is repriced based on prevailing market rates, which is often when borrowers find refinancing makes sense. Always verify current rates directly with Security Bank or through Nook, as rates are subject to change.
Yes — if your current loan has been repriced and your rate is now higher than what's available in the market, refinancing to a new lender (or even back to Security Bank on a fresh fixed-rate period) could reduce your monthly payment significantly. Through Nook, you can compare Security Bank's refinance offering against other partner banks at no cost to you. The process typically takes around 23 days for Security Bank approvals.
Security Bank requires a minimum monthly income of ₱50,000 and a maximum debt-to-income ratio of 40%.
