Computing your BDO housing loan monthly payment doesn't have to be complicated. Whether you're buying your first home, refinancing an existing loan, or simply trying to understand how much you can afford, knowing how to break down your monthly amortization gives you the power to make smarter financial decisions. BDO Unibank — one of the Philippines' largest banks and a Nook partner — currently offers a 1-Year Fixed rate of 6.00% p.a., making it one of the more competitive options available to Filipino homebuyers in 2026.
This guide walks you through the exact formula used to compute BDO housing loan monthly payments, with sample computations for loan amounts of 1,000,000, 2,000,000, 3,000,000, and 5,000,000 pesos across 15, 20, and 25-year terms. If you already have an existing home loan and want to check whether refinancing through Nook could lower your rate, review BDO's home loan eligibility and requirements here — Nook's service is 100% free to borrowers.
BDO uses the standard amortizing loan formula, which spreads your total principal and interest evenly across all monthly payments over your chosen loan term. The formula is:
M = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
Where:
- M = Monthly payment
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of monthly payments (loan term in years × 12)
For example, using BDO's 1-Year Fixed rate of 6.00% p.a., your monthly rate (r) would be 6.00% ÷ 12 = 0.50% or 0.005. This formula gives you your fixed monthly amortization during the fixed-rate period. After the fixed period ends, your rate will be repriced based on prevailing market rates, and your monthly payment will be recalculated accordingly.
Note: Interest rates are subject to change. Always verify the latest rates directly with BDO or through Nook before making financial decisions.
Here are the computed monthly payments for a 1,000,000 peso BDO housing loan at 6.00% p.a. (1-Year Fixed rate) across different loan terms:
| Loan Term | Monthly Payment | Total Interest Paid | Total Amount Paid |
|---|---|---|---|
| 15 years (180 months) | 8,439 | 518,920 | 1,518,920 |
| 20 years (240 months) | 7,165 | 719,600 | 1,719,600 |
| 25 years (300 months) | 6,443 | 932,900 | 1,932,900 |
A shorter loan term means higher monthly payments but significantly less interest paid over the life of the loan. A 15-year term versus a 25-year term saves you approximately 413,980 pesos in total interest on a 1M loan — but requires about 2,000 more per month.
Figures are estimates based on a fixed 6.00% p.a. rate for the full loan term. Actual payments will vary after the fixed period repricing. Verify current rates with BDO or Nook.
Here are the computed monthly payments for a 2,000,000 peso BDO housing loan at 6.00% p.a. (1-Year Fixed rate):
| Loan Term | Monthly Payment | Total Interest Paid | Total Amount Paid |
|---|---|---|---|
| 15 years (180 months) | 16,878 | 1,037,840 | 3,037,840 |
| 20 years (240 months) | 14,330 | 1,439,200 | 3,439,200 |
| 25 years (300 months) | 12,886 | 1,865,800 | 3,865,800 |
For a 2M loan over 20 years, you'd need a monthly income of at least 35,825 pesos to meet a standard 40% debt-to-income (DTI) ratio — though BDO requires a minimum monthly income of 50,000 pesos to qualify. To understand exactly what documents and qualifications you'll need, see the full BDO home loan requirements guide here.

Here are the computed monthly payments for a 3,000,000 peso BDO housing loan at 6.00% p.a. (1-Year Fixed rate):
| Loan Term | Monthly Payment | Total Interest Paid | Total Amount Paid |
|---|---|---|---|
| 15 years (180 months) | 25,317 | 1,557,060 | 4,557,060 |
| 20 years (240 months) | 21,495 | 2,158,800 | 5,158,800 |
| 25 years (300 months) | 19,329 | 2,798,700 | 5,798,700 |
At the 20-year term, a 3M BDO loan at 6.00% costs approximately 21,495 per month. To qualify under a 40% DTI requirement, you'd need a gross monthly income of roughly 53,738 pesos — which is just above BDO's 50,000 peso minimum income threshold, making this a manageable qualification target for many professionals and dual-income households.

Here are the computed monthly payments for a 5,000,000 peso BDO housing loan at 6.00% p.a. (1-Year Fixed rate):
| Loan Term | Monthly Payment | Total Interest Paid | Total Amount Paid |
|---|---|---|---|
| 15 years (180 months) | 42,195 | 2,595,100 | 7,595,100 |
| 20 years (240 months) | 35,825 | 3,598,000 | 8,598,000 |
| 25 years (300 months) | 32,215 | 4,664,500 | 9,664,500 |
A 5M loan over 25 years costs 32,215 per month but results in over 4,664,500 pesos in total interest — nearly the same again as the original loan amount. Borrowers with higher loan amounts should strongly consider a 15 or 20-year term if their income allows, or explore refinancing to a lower rate. At 5.99% — the best rate currently available through Nook — a 5M loan over 20 years would cost approximately 35,757 per month, saving thousands over time compared to higher-rate loans.

BDO Unibank currently offers the following housing loan rates through Nook in 2026:
- 1-Year Fixed Rate: 6.00% p.a.
- Home Equity Rate: 6.00% p.a.
These rates apply during the fixed-rate period only. After the initial fixed period ends (e.g., after 1 year for the 1-Year Fixed product), your interest rate will be repriced based on prevailing market rates and BDO's board rate at the time. This means your monthly payment can go up or down after repricing.
BDO's 6.00% rate is competitive when benchmarked against the Philippine market average, where many homeowners are currently paying between 7% and 10% on existing loans. If you locked in a rate above 6.00% in previous years, you may benefit from refinancing — Nook can compare BDO against other lenders to find your best option at no cost to you.
Interest rates are subject to change without prior notice. Always confirm the latest rates with BDO directly or through your Nook advisor.
The fixed-rate period is the duration during which your interest rate — and therefore your monthly amortization — stays the same. BDO's standard housing loan product offers a 1-Year Fixed Rate at 6.00% p.a., meaning your monthly payment is locked for the first 12 months.
Here's how this affects your loan computation in practice:
- During the fixed period: Your monthly payment is calculated using the fixed rate (6.00%) and remains constant. This is the figure shown in the sample computations in this guide.
- After the fixed period: Your rate is repriced to BDO's prevailing rate. If rates have risen, your new monthly payment will be higher; if rates have fallen, it could be lower.
- Planning ahead: When budgeting for your home loan, it's wise to stress-test your affordability at a rate 1-2 percentage points higher than the current fixed rate to ensure you can still manage repayments after repricing.
If you're concerned about rate volatility after your fixed period ends, refinancing into a new fixed-rate loan through Nook every few years can be a smart strategy to lock in competitive rates consistently — at zero cost to you as a borrower.
BDO requires a minimum monthly gross income of 50,000 pesos to qualify for a housing loan. This applies across all eligible employment types, which include:
- Private sector employees
- Government employees
- BPO workers
- OFWs and seafarers
- Self-employed individuals
- Professionals (doctors, lawyers, accountants, etc.)
Beyond the minimum income floor, BDO also applies a maximum Debt-to-Income (DTI) ratio of 40%. This means your total monthly debt obligations — including your new housing loan payment — cannot exceed 40% of your gross monthly income.
Quick income-to-loan reference at 6.00% p.a., 20-year term:
| Loan Amount | Monthly Payment | Minimum Income Needed (40% DTI) |
|---|---|---|
| 1,000,000 | 7,165 | 17,913 (but 50,000 min applies) |
| 2,000,000 | 14,330 | 35,825 (but 50,000 min applies) |
| 3,000,000 | 21,495 | 53,738 |
| 5,000,000 | 35,825 | 89,563 |
Note that existing debts (car loans, credit card minimums, personal loans) will reduce how much of your income is available for housing loan qualification.
Yes — refinancing is one of the most effective ways to reduce your monthly housing loan payment if your current interest rate is higher than what's available today. Many Filipino homeowners are currently paying between 7% and 10% on home loans taken out in previous years. Refinancing to 6.00% (BDO's current rate through Nook) or even 5.99% (the best available rate through Nook) can produce significant monthly savings.
Example: Refinancing a 3,000,000 loan with 20 years remaining
| Scenario | Rate | Monthly Payment | Monthly Savings |
|---|---|---|---|
| Current loan (typical rate) | 8.50% | 26,099 | — |
| Refinanced via Nook (BDO) | 6.00% | 21,495 | 4,604 |
| Refinanced via Nook (best rate) | 5.99% | 21,477 | 4,622 |
A savings of 4,604 per month adds up to 55,248 per year — and over 1,104,960 pesos over 20 years. Nook makes it easy to refinance by comparing multiple banks simultaneously and handling all paperwork on your behalf, at absolutely no cost to you as a borrower.
