Housing LoanAmortization Calculator
Compute your estimated monthly amortization for Pag-IBIG, bank, or in-house financing. Switch to From Loan Amount to type a loan principal directly, or use the back-solver below the result panel to pin a target monthly payment and let the tool find the term, rate, or principal that matches.
Frequently Asked Questions
How is monthly amortization calculated?
Monthly amortization is calculated using the standard amortization formula:
\[M = P \times \frac{r\,(1+r)^n}{(1+r)^n - 1}\]
Where:
- \(P\) = loan amount (principal)
- \(r\) = monthly interest rate \(\left(\frac{\text{Annual Rate}}{12}\right)\)
- \(n\) = total number of months
Early payments are mostly interest; later payments are mostly principal. This calculator applies the formula automatically based on your inputs.

How is required monthly income calculated?
Required income is derived from the DTI (Debt-to-Income) ratio:
\[\text{Required Income} = \frac{\text{Monthly Amortization}}{\text{DTI Ratio}}\]
For example, with Pag-IBIG’s 35% DTI and a ₱15,000 monthly amortization:
\[\frac{15{,}000}{0.35} \approx 42{,}857\]
This means you need at least ₱42,857 gross monthly income to qualify.
