Anyone Knows the Formula for computing loans and interest. These are the only terms that I know.

Principal Loan
Net from the Principal
interest per month
Monthly amortization

Example, I have a loan of 30,000 and the net is 27,960. The Advance Interest is 1,140 and Processing fee 900. The loan is payable for 5 months semi-monthly equivalent for 10 payments. This loan is from a lending firm... Dako jud kaayo interest, pero la man tay mahims kundi utang nalang... PLease help mga bro...
