I am not sure how to calculate how much additional funding if any will be needed this year if the companies sales are expected to grow at a rate of 25% from the 2013 to 2014. I have the following figures. What steps and information are needed to solve for this solution?

Say total sales in 2013 were $1,000,000 and the 2013 balance sheet is:

Cash$ 100,000

Accounts receivable$ 200,000

Inventories$ 200,000

Net fixed assets$500,000(Fixed assets were used at 80% of capacity last year and its current assets were fully utilized, Fixed assets would grow at the same rate as sales if they were used at full capacity)

Accounts payable$ 50,000

Notes payable$150,000

Accruals$50,000

Long-term debt$400,000

Common stock$100,000

Retained earnings$250,000

Total assets$1,000,000 (All assets will increase at the same rate as sales except fixed assets which have excess capacity)

Total liabilities and equity $1,000,000

After-tax profit margin is 10% and its payout ratio is 75%.
