Monthly interest payable = loan principal × monthly interest rate ×[( 1+ monthly interest rate) repayment months -( 1+ monthly interest rate) (repayment month serial number-1)] ÷ [(1+monthly interest rate) repayment months -650.
Monthly repayment principal = loan principal × monthly interest rate ×( 1+ monthly interest rate) ÷ (repayment month serial number-1)÷[( 1+ monthly interest rate) repayment months-1]
Total interest = repayment months × monthly repayment amount-loan principal
Whether it is cost-effective to repay the loan in advance depends on how you arrange the funds for prepayment. If there are more important uses, it is not cost-effective to repay in advance. If there is no other use, early repayment can reduce interest and be cost-effective.
