M/s ABC has an existing sales of Rs.50 lakhs and permits a credit period of 30 days to its customers.  The firm cost of capital is 10% and the ratio of variable cost to sales is 85. The firm is contemplating on rising the credit period to 60 days that would result in raised sales of Rs.5 lakhs.  The bad debts on raised sales are expected to be 8%.  The tax rate for M/s ABC is 40 percent. Must the firm extend the credit period?

Solution

? I = (ACP_n - ACP₀) [S0/360] + V(ACP_n)( ?S/360)

? I = (60 - 30) [50/360] + 8.5 × 60 × 5/360

? I = (30) × 50/360 + .708333

?I = 4.8749997 × 1, 00,000

= 4, 87,500

= 4, 874,99.9

 ?NP = [ ?S (1 - V ) - ? Sb_n ] (1 - t ) - k?I

 = [5 (015 ) - 5 × .08 ] (1 - 04 ) - .10 × 4,87 ,500

=  [.75 - .4] (.6) - 4.875000

= (.35 ) (-6) - .48750

= (.21 - .48750 ) × 1,00 ,000

= - 27 ,750

The raise in credit period results in a negative net profit thus the credit period must not be extended.
