Assume this firm is operating at full capacity. Also assume that assets, costs, and current liabilities vary directly with sales. The dividend payout ratio is constant. What is the external financing need if sales increase by 14 percent?

external financing needed = EFN = [(total assets/total sales) x ($ Δ sales)] - [(total current liabilities/total sales) x ($ Δ sales)] - [profit margin x forecasted sales in $ x (1 - dividend payout ratio)]

total assets = $48,900

total sales = $42,700

$ Δ sales = $5,978

current liabilities = $3,650

profit margin = net income / sales = 0.129

forecasted sales = $48,678

dividends payout ratio = dividends / net income = 0.35

EFN = [($48,900/$42,700) x ($5,978)] - [($3,650/$42,700) x ($5,978)] - [0.129 x $48,678 x (1 - 0.35)]

EFN = $6,846 - $511 - $4,081.65 = $2,253.35
