Debts of $6800.00 due three months from now and $2600.00 due twenty-one months from now are to be settled by two equal payments due in three months and nine months from now respectively. Determine the size of the equal replacement payments if interest is 5.5% p.a. compounded quarterly.
Step 1: Find the Present Value of debts due three months and twenty one months from now
Interest rate = 5.5% per annum or 1.375% per quarter (since it is compounded quarterly)
a. Debt due in 3 months from now or 1 quarter from now = $6,800
Present Value of Debt due in 3 months = $6,800 * Discount factor of 1.375% for 3 months or 1 quarter
=$6,800*(1/(1+1.375%)^1) = $6,800*0.98644 = $6,707.79
b. Debt due in 21 months from now or 7 quarters (21/3) from now = $2,600
Present Value of Debt due in 21 months = $2,600 * Discount factor of 1.375% for 21 months or 7 quarters
=$2,600*(1/(1+1.375%)^7) = $2,600*0.90883 = $2,362.96
c. Total Present Value = $6,707.79 + $2,362.96 = $9,070.75
Step 2: Find the Equal payment of Present Value of Total Debt
1st equal payment in 3 months or 1 quarter.
Present Value Factor of payment in 3 months or 1 Quarter from now = (1/(1+1.375%)^1) = 0.98644
2nd equal payment in 9 months or 3 quarters.
Present Value Factor of payment in 9 months or 3 Quarter from now = (1/(1+1.375%)^3) = 0.95986
Total Present Value Factor of two equal payments= 0.98644 + 0.95986 = 1.94630
Equal Payment to be made in 3 months and 9 months from now = Present Value of debt / Total Present Value Factor of two equal payments
= $9,070.75/1.94630 = $4,660.51
Thus, size of the equal replacement payments = $4,660.51
