The company plans to incorporate a sinking fund of $60,000 at the end of 5 years with the rate of interest as 4%. The company has to determine the periodic annual payments to formulate the sinking fund.

The Periodic amount would be determined as follows: –

$60,000 = A * (1+0.04)^5 -1 /0.04
$60,000 = A * (1+0.4)^5 -1 /0.04
$60,000 = A * (1.2167 -1) /0.04
$60,000 = A * (0.2167) /0.04
$60,000 = A * 5.4163
A = $60,000 / 5.4163 = $11,077.6
