Understanding the Retained Earnings Breakpoint
What is the Retained Earnings Breakpoint?
The Retained Earnings Breakpoint is a level of total new capital investment. Up to this level, the company can finance the equity portion of its target capital structure using cheaper, internally generated retained earnings. Once total new investment exceeds this breakpoint, the company must issue new common stock to meet its equity financing needs, which is typically more expensive due to flotation costs and market perception.
Why is it Important?
Calculating this breakpoint is crucial when determining a company's Marginal Cost of Capital (MCC) and Weighted Average Cost of Capital (WACC). The cost of equity changes at this breakpoint, influencing the WACC for investments above the breakpoint compared to those below it.
The Formula
The Retained Earnings Breakpoint is calculated using this formula:
Retained Earnings Breakpoint = Available Retained Earnings / Target Equity Proportion
Where the Target Equity Proportion is the target equity percentage expressed as a decimal (e.g., 60% becomes 0.60).
Retained Earnings Breakpoint Examples
Understand how different scenarios impact the breakpoint:
Example 1: Standard Calculation
Scenario: A company has $2,000,000 in retained earnings and a target capital structure of 50% Equity and 50% Debt.
1. Known Values: Available Retained Earnings = $2,000,000, Target Equity Percentage = 50%.
2. Convert Percentage: Target Equity Proportion = 50% / 100 = 0.50.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = $2,000,000 / 0.50
5. Result: Breakpoint = $4,000,000.
Conclusion: The company can fund up to $4,000,000 of total new investment before needing to issue new stock. At this $4M level, the $2M equity requirement (50% of $4M) exactly uses up the $2M in retained earnings.
Example 2: High Retained Earnings, Low Equity %
Scenario: A very profitable company has $5,000,000 in retained earnings but a conservative target capital structure of 30% Equity and 70% Debt.
1. Known Values: Available Retained Earnings = $5,000,000, Target Equity Percentage = 30%.
2. Convert Percentage: Target Equity Proportion = 30% / 100 = 0.30.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = $5,000,000 / 0.30
5. Result: Breakpoint ≈ $16,666,667.
Conclusion: The company can fund a large amount of total new investment (about $16.67M) before using all its retained earnings for the 30% equity portion ($16.67M * 30% ≈ $5M).
Example 3: Low Retained Earnings, High Equity %
Scenario: A company has modest retained earnings of $500,000 but a target capital structure of 80% Equity and 20% Debt.
1. Known Values: Available Retained Earnings = $500,000, Target Equity Percentage = 80%.
2. Convert Percentage: Target Equity Proportion = 80% / 100 = 0.80.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = $500,000 / 0.80
5. Result: Breakpoint = $625,000.
Conclusion: The breakpoint is relatively low ($625,000 total investment). Beyond this level, funding the high 80% equity portion requires external stock issuance.
Example 4: Zero Retained Earnings
Scenario: A new or unprofitable company has $0 in available retained earnings and a target equity percentage of 60%.
1. Known Values: Available Retained Earnings = $0, Target Equity Percentage = 60%.
2. Convert Percentage: Target Equity Proportion = 60% / 100 = 0.60.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = $0 / 0.60
5. Result: Breakpoint = $0.
Conclusion: The breakpoint is $0. Any new investment requiring equity financing will immediately require the issuance of new common stock, as there are no retained earnings to use.
Example 5: 100% Equity Target
Scenario: A company plans to fund new investments entirely with equity (100% Equity, 0% Debt) and has $1,000,000 in retained earnings.
1. Known Values: Available Retained Earnings = $1,000,000, Target Equity Percentage = 100%.
2. Convert Percentage: Target Equity Proportion = 100% / 100 = 1.00.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = $1,000,000 / 1.00
5. Result: Breakpoint = $1,000,000.
Conclusion: When the target equity is 100%, the breakpoint is simply the total amount of available retained earnings. Any new investment beyond this amount requires issuing new stock.
Example 6: Using Different Units (Millions)
Scenario: A large corporation has $50 Million in retained earnings and a target equity percentage of 40%.
1. Known Values: Available Retained Earnings = 50 (Million $), Target Equity Percentage = 40%.
2. Convert Percentage: Target Equity Proportion = 40% / 100 = 0.40.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = 50 / 0.40
5. Result: Breakpoint = 125 (Million $).
Conclusion: The company's breakpoint is $125 Million of total new investment. Consistent units (millions in this case) are key.
Example 7: Investment Required vs. Breakpoint
Scenario: A company calculated its breakpoint is $10,000,000. It needs to fund a new project costing $12,000,000. How much of the equity portion requires new stock?
1. Known Values: Breakpoint = $10,000,000, Project Cost = $12,000,000, Assume Target Equity % was 50% (meaning Retained Earnings were $5M).
2. Equity needed for project: $12,000,000 * 50% = $6,000,000.
3. Equity from Retained Earnings (up to breakpoint): At the $10M breakpoint, $5M of retained earnings are used (50% of $10M).
4. Equity needed beyond breakpoint: The project is $2M beyond the breakpoint ($12M - $10M). The equity portion of this additional $2M is $2M * 50% = $1,000,000.
5. Calculation of New Stock needed: Total equity needed ($6M) minus Retained Earnings ($5M) = $1,000,000.
Conclusion: $1,000,000 of the total $6,000,000 equity required for the project will need to be raised by issuing new stock.
Example 8: Impact of Changing Equity Target
Scenario: A company has $1,000,000 in retained earnings. Their current target equity is 40%. They are considering changing it to 50% or 30%. How does this affect the breakpoint?
1. Known Values: Available Retained Earnings = $1,000,000.
2. Calculate Breakpoint at 40% Equity: $1,000,000 / 0.40 = $2,500,000.
3. Calculate Breakpoint at 50% Equity: $1,000,000 / 0.50 = $2,000,000.
4. Calculate Breakpoint at 30% Equity: $1,000,000 / 0.30 ≈ $3,333,333.
Conclusion: A higher target equity percentage for a given amount of retained earnings results in a *lower* breakpoint (you use up retained earnings faster for the equity portion). A lower target equity percentage results in a *higher* breakpoint.
Example 9: Negative Retained Earnings (Losses)
Scenario: A company has accumulated losses, resulting in negative retained earnings (-$500,000), and a target equity percentage of 70%.
1. Known Values: Available Retained Earnings = -$500,000, Target Equity Percentage = 70%.
2. Input Handling: While the calculator enforces non-negative input, in reality, negative retained earnings mean there are *no* internal funds available for equity financing.
Conclusion: In this scenario, the available retained earnings for *new* investment equity is effectively zero. Any new investment requiring equity financing would immediately require issuing new stock. The breakpoint is $0.
Example 10: Very Small Equity Target
Scenario: A company with $1,000,000 in retained earnings has an extremely low target equity percentage of 5%.
1. Known Values: Available Retained Earnings = $1,000,000, Target Equity Percentage = 5%.
2. Convert Percentage: Target Equity Proportion = 5% / 100 = 0.05.
3. Formula: Breakpoint = Retained Earnings / Target Equity Proportion
4. Calculation: Breakpoint = $1,000,000 / 0.05
5. Result: Breakpoint = $20,000,000.
Conclusion: With a very low equity requirement per dollar of investment, the company can fund a large total investment amount ($20M) using its retained earnings ($20M * 5% = $1M) before needing external equity.
Frequently Asked Questions about the Retained Earnings Breakpoint
1. What is the Retained Earnings Breakpoint?
It's the maximum level of total new investment a company can fund using only its internal retained earnings for the equity portion, before needing to issue potentially more expensive new common stock.
2. How is the breakpoint calculated?
The formula is: Retained Earnings Breakpoint = Available Retained Earnings / Target Equity Proportion (where the target equity percentage is converted to a decimal).
3. Why is this breakpoint important for companies?
It's essential for calculating the company's Marginal Cost of Capital (MCC) and Weighted Average Cost of Capital (WACC). The cost of equity capital changes at the breakpoint, leading to a higher WACC for investments exceeding the breakpoint.
4. What inputs do I need for the calculator?
You need the total amount of available retained earnings (money not paid out as dividends) and the company's target percentage of equity in its capital structure.
5. Does the breakpoint mean the company has no more money available?
Not necessarily. It means the company has exhausted the *retained earnings* designated to fund the *equity portion* of new projects based on its target capital structure. It may still have debt capacity or other internal funds, but for equity, it now needs external sources (new stock).
6. Why is issuing new common stock usually more expensive than using retained earnings?
New stock issuance incurs flotation costs (fees to investment bankers, legal fees, etc.) and can sometimes negatively signal the market (suggesting the company believes its stock is overvalued or needs cash badly), potentially lowering the stock price and increasing the required return for investors.
7. Can the breakpoint be zero?
Yes, if the company has zero or negative available retained earnings, the breakpoint is zero. Any new investment requiring equity will immediately necessitate issuing new stock.
8. Does the target capital structure affect the breakpoint?
Absolutely. For a given amount of retained earnings, a higher target equity percentage results in a lower breakpoint (you use up retained earnings faster), while a lower target equity percentage results in a higher breakpoint.
9. Where does "Available Retained Earnings" come from?
It comes from the company's cumulative profits that have not been distributed to shareholders as dividends. The amount "available" for new investment is typically the balance shown on the balance sheet or adjusted for any amounts designated for other purposes.
10. Does this calculation consider the cost of debt?
The breakpoint calculation itself focuses only on the equity side funded by retained earnings. However, the concept of the breakpoint is critical *because* it indicates when the overall WACC might change due to a change in the cost of equity (from retained earnings to new stock), which is part of the overall cost of capital that includes debt.
