Planning to take out a Security Bank housing loan in 2026? Before you commit, it pays to know exactly what your monthly amortization will look like. Security Bank is one of the Philippines' most competitive home loan lenders, currently offering a 1-year fixed rate of 6.99% p.a. and a 5-year fixed rate of 6.75% p.a. — well below what many homeowners are paying today. Use Nook's Security Bank housing loan calculator to estimate your monthly payment based on your loan amount, term, and preferred fixing period.
Whether you're buying a ready-for-occupancy unit, refinancing an existing loan, or tapping your home equity, this FAQ guide breaks down everything you need to know about how Security Bank calculates your monthly amortization — and how Nook can help you apply for free. Note that all interest rates are subject to change; always verify current rates directly with Security Bank or through Nook before making a financial decision.
A housing loan calculator uses three inputs to estimate your monthly amortization: the loan amount, the loan term (in years), and the interest rate. It applies the standard amortization formula — breaking your payment into principal and interest — to produce a fixed monthly figure for the chosen fixing period.
For example, on a Security Bank loan at the 5-year fixed rate of 6.75% p.a., your monthly payment is calculated as:
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n − 1]
Where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. After your fixed period ends, your rate is re-priced to prevailing market rates, which may change your monthly payment. Always factor this in when budgeting.
As of 2026, Security Bank offers the following indicative housing loan rates through Nook:
- 1-Year Fixed: 6.99% p.a.
- 5-Year Fixed: 6.75% p.a.
- Home Equity: 7.50% p.a.
These are among the most competitive rates available in the Philippine market. Many existing homeowners are currently paying between 7% and 10% on their current loans — meaning a switch to Security Bank through Nook's refinancing service could result in significant monthly savings.

Here are sample monthly amortization estimates for a 3,000,000 Security Bank housing loan at the 5-year fixed rate of 6.75% p.a.:
- 15-year term: approximately 26,560 per month
- 20-year term: approximately 22,730 per month
- 25-year term: approximately 20,760 per month
At the 1-year fixed rate of 6.99% p.a. over 20 years, the monthly payment would be approximately 23,250. A longer term reduces your monthly outlay but increases total interest paid over the life of the loan. Use Nook's Security Bank monthly payment calculator to run your own numbers instantly.
These figures are estimates only. Actual amortization may vary based on final approved rate, fees, and loan structure.
Security Bank typically accommodates home loans ranging from around 1,500,000 up to 10,000,000 or more, depending on the property value, your income, and your debt-to-income ratio. The maximum loanable amount is generally up to 80% of the appraised property value for purchases, and may vary for refinancing and home equity purposes.
For reference, here is how monthly payments scale across common loan amounts at Security Bank's 5-year fixed rate of 6.75% p.a. over a 20-year term:
- 1,500,000: approximately 11,370 per month
- 3,000,000: approximately 22,730 per month
- 5,000,000: approximately 37,890 per month
- 7,500,000: approximately 56,830 per month
- 10,000,000: approximately 75,770 per month
All figures are estimates. Final loan amounts are subject to Security Bank's credit assessment and property appraisal.
Yes — the fixing period directly determines the interest rate applied during that period, which in turn affects your monthly amortization. A longer fixing period typically comes with a lower rate (more certainty for the bank), which is why Security Bank's 5-year fixed rate at 6.75% p.a. is lower than its 1-year fixed rate of 6.99% p.a.
For a 5,000,000 loan over 20 years, the difference looks like this:
- 1-Year Fixed at 6.99%: approximately 38,740 per month
- 5-Year Fixed at 6.75%: approximately 37,890 per month
That's a difference of roughly 850 per month, or about 10,200 per year — just by choosing the right fixing period. After your fixed term ends, your rate resets to the prevailing re-pricing rate, so plan accordingly.
Security Bank requires a minimum monthly income of 50,000 for housing loan applicants. This applies across all employment types — including salaried employees, self-employed individuals, and professionals.
Security Bank also enforces a maximum debt-to-income (DTI) ratio of 40%. This means your total monthly debt obligations — including the proposed housing loan payment — must not exceed 40% of your gross monthly income. For example, if you earn 80,000 per month, your maximum allowable total monthly debt payments would be 32,000.
This DTI cap is important to factor into your calculations. If you have existing car loans, credit card minimum payments, or other debts, these will reduce the maximum housing loan amount you can qualify for.
Security Bank's typical loan approval timeline is approximately 23 banking days from submission of complete documents. This is a competitive turnaround compared to many other Philippine banks, which can take 30–45 days or more.
Factors that can speed up or delay approval include the completeness of your document submission, property appraisal scheduling, and any additional verification required for self-employed or OFW applicants. Applying through Nook helps streamline the process — our team reviews your documents before submission to minimize back-and-forth with the bank.
Yes. Security Bank accepts applications from a wide range of employment types, including:
- Private-sector employees
- Government employees
- BPO workers
- OFWs and seafarers
- Self-employed individuals and business owners
- Licensed professionals (doctors, lawyers, CPAs, etc.)
- Freelancers
OFWs and freelancers typically need to provide additional income documentation — such as remittance records, contracts, or audited financial statements — to verify stable income. Nook's mortgage specialists can guide you through the exact requirements for your employment type, making the application process significantly smoother.

If you're refinancing, simply input your outstanding loan balance (not your original loan amount) as the principal. This is the amount you still owe on your current mortgage. Then choose your preferred new loan term and apply Security Bank's refinancing rate to estimate your new monthly payment.
For example, if you have an outstanding balance of 4,000,000 and are currently paying 9.00% p.a. over a remaining 18-year term, your current monthly payment is approximately 38,300. Refinancing to Security Bank at 6.75% p.a. (5-year fixed) over a fresh 20-year term would bring your monthly payment down to approximately 30,310 — a saving of roughly 7,990 per month or over 95,880 per year.
Nook's best available refinance rate is currently 5.99% p.a., subject to eligibility. Apply through Nook for free to find out the best rate available for your specific loan situation.
