Answer:
To find the self-supporting growth rate, we need to find the amount of increase in assets that can be funded by the increase in spontaneous liabilities and retained earnings, without requiring external financing.
First, let's calculate the company's profit margin:
Profit Margin = Net Income / Sales
0.07 = Net Income / 2,000,000
Solving for Net Income:
Net Income = 0.07 * 2,000,000 = 140,000
Next, let's calculate the amount of retained earnings that will be available for funding growth:
Retained Earnings = Net Income * (1 - Payout Ratio)
Retained Earnings = 140,000 * (1 - 0.75) = 35,000
Now, let's calculate the increase in assets that can be funded by spontaneous liabilities and retained earnings:
Increase in Assets = Self-Supporting Growth Rate * Total Assets
Increase in Assets = Self-Supporting Growth Rate * 1,100,000
Increase in Spontaneous Liabilities = Self-Supporting Growth Rate * Spontaneous Liabilities
Increase in Spontaneous Liabilities = Self-Supporting Growth Rate * (Notes Payable + Accounts Payable + Accruals)
Increase in Spontaneous Liabilities = Self-Supporting Growth Rate * (300,000 + 500,000 + 200,000) = Self-Supporting Growth Rate * 1,000,000
Since the increase in assets must equal the increase in spontaneous liabilities and retained earnings, we can set these two expressions equal to each other and solve for the self-supporting growth rate:
Self-Supporting Growth Rate * 1,100,000 = Self-Supporting Growth Rate * 1,000,000 + 35,000
Self-Supporting Growth Rate * 100,000 = 35,000
Self-Supporting Growth Rate = 0.35 or 35%
Therefore, the company can achieve a sales increase of up to 35% without requiring external financing, assuming its profit margin, payout ratio, and spontaneous liabilities remain constant.
