Understanding your results
The affordability meter tracks back-end DTI using gross income — the same income figure many lenders start from when screening personal loans and auto loans. If your bar lands in the green zone (≤30% toward total debt service), you are closer to common conservative budgets. Orange and red zones signal stress: you may still be approved, but emergency savings and insurance should be in place.
What is debt-to-income ratio?
DTI divides total monthly obligations by monthly income. Front-end ratios sometimes focus only on housing; back-end ratios include all recurring debts. This calculator emphasizes back-end DTI because most Filipinos juggle multiple obligations — motorcycle loans, credit cards, and family support remittances.
Safe DTI percentages
Rules of thumb vary: 28/36 rules appear in US literature; Philippine banks may use internal score cards instead of publishing a single DTI cap. Treat 30% of gross as a budgeting line, not a guarantee of approval. If your DTI is “safe” but liquidity is tight, shorten the loan term only after stress-testing emergencies.
How banks decide if you qualify
Underwriters look at payslips, ITRs, bank statements, and bureau scores. Self-employed applicants may need audited financials or longer track records. Collateral and co-makers can shift outcomes even when DTI looks borderline.
Examples with different salary levels
A ₱40,000 gross earner with ₱10,000 existing loans has ₱2,000 headroom before hitting a 30% gross DTI (₱12,000 total). A ₱120,000 gross earner with the same ₱10,000 debt can support larger new payments — but lifestyle inflation often eats the difference unless you plan savings first.
Common loan mistakes
- Comparing only monthly payment without checking total interest.
- Taking the longest term to minimize payment while doubling finance charges.
- Co-signing loans without tracking them in your own DTI.
Stress-testing your budget
A loan that passes a 30% DTI ratio on paper can still feel tight if you support extended family, pay rent that rises yearly, or rely on variable commissions. Before signing, simulate one bad month: lower income, higher utilities, and a medical bill. If the new installment still leaves room for savings, you are closer to a sustainable choice.
Rates quoted in marketing materials may exclude insurance, processing fees, or late fees. Add those costs mentally (or line-by-line in a spreadsheet) before comparing lenders. Our amortization calculator on the general loan page can show how small rate differences change lifetime interest.
