How is the monthly amortization calculated?

This tool uses the standard amortization formula: M = P [ i(1+i)^n ] / [ (1+i)^n - 1 ], where P is the loan amount (property price minus down payment), i is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments (loan term in years multiplied by 12). This assumes a fixed rate for the full term.

Does this include Pag-IBIG or bank processing fees?

No. This calculator computes the pure loan amortization on the principal and rate you enter. Processing fees, mortgage redemption insurance, fire insurance, notarial fees, and other closing costs are set by individual lenders and are not included here.

What down payment is typical for a Philippine home loan?

Banks commonly require 20 percent of the property price as down payment, with the remaining 80 percent financed. Pag-IBIG Fund loans sometimes allow a smaller down payment depending on the loan amount and borrower eligibility. Check the exact requirement with your chosen lender.

Is the interest rate fixed for the whole loan term?

This calculator assumes a fixed rate for the full term. In practice, many Philippine home loans reprice periodically, commonly every 1, 3, or 5 years, so the actual rate and monthly amortization can change after each repricing period.

How does the loan term affect my monthly amortization?

A longer term, such as 20 or 30 years, lowers the monthly amortization but increases the total interest paid over the life of the loan. A shorter term raises the monthly payment but reduces total interest since the balance is paid off faster.
