December Was Different This Year
Every December, Carla Reyes did the same thing. The 38-year-old marketing manager from Makati would receive her 13th month pay — around 72,000 pesos — and immediately start a mental list: Christmas gifts, a family trip to Bohol, maybe a new ref. The money was gone by January 10.
But December 2023 was different. Sitting at her kitchen table in their condo in Mandaluyong, Carla was staring at her BDO home loan statement. Her rate had just repriced to 9.25% per annum after her fixed period ended. Her monthly amortization had jumped from 18,400 pesos to 22,600 pesos — an extra 4,200 pesos every single month.
"I literally could not breathe when I saw that number," she recalled. "That's groceries. That's my daughter's piano lessons. Just gone."
The Question She Kept Asking
Carla had heard about refinancing but always assumed it was complicated, expensive, or — the fear she never said out loud — that she wouldn't qualify. Her base salary was 56,000 pesos a month. She knew banks looked at income carefully, and she worried her numbers weren't impressive enough on paper.
What she didn't know was that her 13th month pay counted.
Not as a bonus that banks politely ignored. As actual, documentable, qualifying income — one that lenders in the Philippines have specific ways of computing. When a borrower receives a consistent 13th month pay (and in Carla's case, she also received a 14th month performance bonus most years), that income can be annualized and factored into the debt-to-income calculation that determines loan eligibility.
"I always thought only my monthly salary mattered," she said. "Nobody ever told me the bonus was part of the picture."
How Banks Actually Treat 13th Month Pay
Here's what Carla learned — and what most Filipino homeowners don't realize:
Philippine banks and Pag-IBIG generally allow borrowers to include their 13th month pay when computing gross monthly income for loan qualification purposes. The standard method is to divide the annual bonus by 12 and add it to the monthly base salary. So if your base pay is 56,000 pesos and your 13th month pay is 56,000 pesos, your qualifying monthly income becomes approximately 60,667 pesos — not 56,000.
That difference matters enormously when lenders calculate your debt-to-income (DTI) ratio. Most banks require that total monthly debt obligations stay below 40% to 50% of gross monthly income. A higher qualifying income means more room for your mortgage payment — and a stronger refinancing application.
For borrowers with a 14th month or performance bonus, many banks will accept two years of payslips and a Certificate of Employment confirming the bonus as regular compensation. The more consistent the income, the more weight lenders give it.
If you've been worried that your income looks thin on paper, it may be worth reading more about refinancing options for borrowers with high debt ratios — because the solution is often in the income calculation, not the debt side.
Carla's Numbers, Recalculated
When Carla submitted her application through Nook, the mortgage specialist walked her through exactly how her income would be presented to lenders.
- Base monthly salary: 56,000 pesos
- 13th month pay (annualized ÷ 12): 4,667 pesos
- 14th month bonus (2-year average, annualized ÷ 12): 3,800 pesos
- Total qualifying monthly income: 64,467 pesos
Her outstanding loan balance was 3,200,000 pesos with approximately 18 years remaining. At her current rate of 9.25%, her monthly payment was 22,600 pesos — which represented about 35% of her base salary alone. A tight but manageable ratio by itself. But with her full qualifying income factored in, her DTI dropped to a very comfortable 35% — well inside what most banks accept.
That clean DTI, combined with her strong credit history and five years of on-time BDO payments, made her an attractive borrower.
Nook submitted her application to multiple lenders simultaneously. Three came back with competitive offers. The best: 5.99% per annum fixed for three years from Security Bank.
What the Numbers Actually Mean
Let's be specific, because the savings are real.
Before refinancing:
Loan balance: 3,200,000 pesos
Interest rate: 9.25% p.a.
Monthly payment: 22,600 pesos
Remaining term: 18 years
After refinancing:
Loan balance: 3,200,000 pesos
Interest rate: 5.99% p.a.
Monthly payment: 18,150 pesos
Remaining term: 18 years
Monthly savings: 4,450 pesos
Annual savings: 53,400 pesos
3-year savings (during fixed period): 160,200 pesos
Over the remaining 18 years of her loan — assuming she continues to refinance strategically — total interest savings exceed 320,000 pesos.
"That's a car," Carla said, laughing. "Or my daughter's college fund. Or both, if I'm disciplined."
The Documents That Made It Work
One thing Carla appreciated was that Nook told her upfront exactly what she needed to document her bonus income. Banks don't guess — they verify. Here's what she gathered:
- Three months of payslips (showing the base salary line clearly)
- Latest ITR (BIR Form 2316) showing total annual compensation including the 13th month
- Certificate of Employment stating her position, tenure, basic salary, and confirmation that 13th and 14th month pay are part of her regular compensation package
- One year of payslips from the previous year, to demonstrate consistency
The Certificate of Employment wording was important. Her HR department initially issued a generic template that only mentioned her base salary. Nook's specialist flagged this and asked HR to add a line explicitly confirming the bonus components. That single change strengthened her application with every bank that reviewed it.
"I never would have known to ask for that," she said. "I would have just submitted what HR gave me and wondered why nobody called back."
Who Else This Applies To
Carla's situation is far more common than most people realize. Millions of Filipino employees receive a 13th month pay — it's mandated by law for private sector workers. Many also receive 14th month pay, mid-year bonuses, or performance incentives that recur annually. Yet a surprising number of homeowners refinancing their loans never think to include these in their income documentation.
The borrowers who benefit most from this income calculation approach tend to be:
- Employees whose base salary looks tight relative to their loan but whose total annual compensation is substantially higher
- Corporate employees with consistent performance bonuses over multiple years
- Government employees who receive year-end bonuses (which are also documentable)
- Employees approaching a salary review who want to lock in a refinance before their income picture improves further
It's a different situation from the self-employment income puzzle — if you're a freelancer or business owner, the income documentation process works differently (you can read about self-employed refinancing in the Philippines here). But for salaried employees with bonus income, the path is more straightforward than most people assume.
What Carla Would Tell You
Carla's refinancing closed in February — six weeks after she first filled out Nook's online form. The process was free. She paid standard government processing fees and a modest appraisal cost, but no broker fees, no application fees charged by Nook.
Her first payment at the new rate was March. She transferred the 4,450 pesos she saved directly into her daughter's education fund. She's done that every month since.
"I spent so long thinking I didn't qualify," she said. "I wish someone had just explained to me that my bonus counted. I would have done this two years ago."
If you're a salaried employee sitting on a home loan with a rate above 7% — and you've been assuming your income isn't strong enough to qualify for something better — it's worth finding out what your full qualifying income actually looks like. You might be surprised how different the number is.
Nook's pre-qualification process takes about three minutes. There's no credit pull at that stage, no commitment, and no fee. You find out where you stand before you decide anything.
