  2. R R R R R R R n n-1 1 n-2 0 2 3 4 Amortization – a debt-repayment scheme wherein the original amount borrowed is repaid by making equal payments periodically If a loan (debt) is repaid on installments (usually in equal amount), then the loan is said to be repaid by amortization method. Each installment payment consists of payment of interest and repayment of principal. All payments form an annuity whose present value is the original loan L. • original loan = L • P S.Y.Tan

  4. OBk • RLk Anyremaining debt after k payments is called outstanding balance ( ) or outstanding liability or remaining liability ( ) or outstanding principal. Outstanding balance (OB) or Remaining Liability (RL) – refers to the amount of debt still unpaid Methods of finding or (i) Prospective Method (n is known) (ii) Retrospective Method (n is not known) S.Y.Tan

  5. R R R R R 1 0 2 k-1 k-2 (n-2) If a loan L is to be repaid by n payments of R, the outstanding balance just after the kth payment denoted by or , is the present value of the (n-k) payments still to be made. k+1 k+2 k (n-1) n • Pn-k • remaining(n-k) payments still to be made • original loan = L R R R R R • k payments already made S.Y.Tan

  6. R R 1 0 2 k-1 k-2 If total number of payments (n) is NOT KNOWN, then we use retrospective method to find the outstanding balance or remaining liability after k payments . k+1 k+2 k obligations = payments • remaining debt on the kth period • Fk • Value of k payments on the kth period • remainingunknown number of payments • k payments already made R R R R R • CD • original loan = L S.Y.Tan

  12. If a loan (debt) is amortized, each installment payment is broken down into interest payment and repayment of principal. A table showing the breakdown of each periodic payment into interest payment (I) and repayment of principal (RP) is known as an amortization schedule. S.Y.Tan
