How to Compute

The easiest way to compute monthly amortization is to multiply the loan amount or principal and the corresponding factor rate depending on loan term and interest rate:

Monthly Amortization = Principal X Factor Rate

• Monthly Amortization – the amount that you will have to pay the bank monthly
• Principal or Loanable Amount – the original amount being borrowed from the bank
• Factor Rate – a pre-computed number that you need to multiply to the principal to find the monthly amortization

For example, lets assume you want to borrow Php3,000,000 for 20 years at 7% interest. To solve for Monthly Amortization, you have to find the corresponding factor rate for 20yrs at 7% interest which is 0.007753 (see Table 1 below).
