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.

What are the current Pag-IBIG housing loan interest rates?
Pag-IBIG housing loan rates vary by loan amount and term. For loans up to PHP 450,000, rates range from 4.5% to 6.5% per year. For higher loan amounts, rates can be 5.5% to 10.5% depending on the term length (up to 30 years). This calculator auto-fills the applicable Pag-IBIG rate tier based on your loan amount.
How much down payment do I need for a housing loan?
The typical down payment for a housing loan in the Philippines is 10–20% of the property price. Pag-IBIG allows as low as 5% for some programs. Bank financing usually requires 10–20%. Use the slider in this calculator to see how different down payment percentages affect your monthly amortization.
What is the maximum Pag-IBIG housing loan term?
The maximum Pag-IBIG housing loan term is 30 years. However, shorter terms (10, 15, or 20 years) typically have lower interest rates. Use this calculator to compare monthly payments across different loan terms.
Can I use this calculator for condo or lot purchases?
Yes, this calculator works for any type of property purchase in the Philippines including houses, condominiums, townhouses, and lots. Simply enter the total contract price or selling price of the property.
What is the difference between Pag-IBIG and bank financing?
Pag-IBIG (HDMF) typically offers lower interest rates (4.5–10.5%) with longer terms (up to 30 years) but has maximum loanable amount limits. Bank financing usually has higher rates (7–9%) but can cover higher property values with faster processing. This calculator lets you compare both options side by side.
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.
