Management Accounting 101: Performance Measurement and Control - Economic Value, Added EVA Calculation Adjustments and Interpretation

What This Is

Economic Value Added (EVA) is a management accounting metric that measures a company's true economic profit by subtracting the cost of capital from net operating profit after taxes (NOPAT). This concept is crucial for managers as it helps them evaluate the financial performance of their investments and make informed decisions about resource allocation. For instance, Toyota uses EVA to evaluate the profitability of its various product lines and make strategic decisions about which products to invest in.

Key Frameworks & Metrics

• Economic Value Added (EVA) = NOPAT? (Capital Invested × WACC) – measures true economic profit after charging for the cost of capital.
• NOPAT = Net Income + (Interest Expense × (1 - Tax Rate)) – adjusts net income for the tax effect of interest expenses.
• Capital Invested = Total Assets - Current Liabilities – represents the amount of capital invested in the business.
• Weighted Average Cost of Capital (WACC) = (Debt × Cost of Debt) + (Equity × Cost of Equity) – represents the average cost of capital for a company.
• Return on Investment (ROI) = Net Income / Total Assets – measures the return on investment, but does not consider the cost of capital.
• Residual Income = Net Income - (Capital Invested × WACC) – measures the income earned by a company above its cost of capital.
• Contribution Margin = Sales - Variable Costs – represents the amount of revenue available to cover fixed costs.
• Contribution Margin Ratio = Contribution Margin / Sales – measures the proportion of sales that contributes to covering fixed costs.

Step-by-Step Process

1. Calculate NOPAT: Start by calculating net income and adjusting it for the tax effect of interest expenses.
2. Calculate Capital Invested: Calculate the total assets and subtract current liabilities to determine the amount of capital invested.
3. Calculate WACC: Calculate the weighted average cost of capital using the cost of debt and equity.
4. Calculate EVA: Subtract the product of capital invested and WACC from NOPAT to determine the economic value added.
5. Analyze EVA: Evaluate the EVA to determine if it is positive or negative, and make decisions accordingly.
6. Consider Adjustments: Consider adjustments to EVA, such as changes in capital structure or market conditions.

Common Mistakes

• Mistake: Treating all costs as relevant when calculating EVA.
• Correction: Only consider costs that are avoidable and relevant to the decision at hand.
• Mistake: Ignoring qualitative factors in make-or-buy decisions.
• Correction: Consider strategic, not just quantitative, factors when making make-or-buy decisions.
• Mistake: Using ROI alone without considering residual income or EVA.
• Correction: Use EVA or residual income to evaluate the true economic profit of an investment.

Decision-Making Tips

• Tip: When faced with a make-or-buy decision, always isolate avoidable costs and consider strategic, not just quantitative, factors.
• Tip: Use EVA or residual income to evaluate the true economic profit of an investment.
• Tip: Consider the impact of changes in capital structure or market conditions on EVA.

Quick Practice Scenario

Scenario: A division rejects a project because its ROI would drop from 18% to 17%. By how much would residual income change if the project cost is $1M and the required rate of return is 12%?

Answer: Residual income would increase by $40,000.

Explanation: Residual income = Net Income - (Capital Invested × WACC). Since the ROI is decreasing, the net income will decrease, but the capital invested will also decrease, resulting in an increase in residual income.

Last-Minute Cram Sheet

• EVA = NOPAT - (Capital Invested × WACC).
• NOPAT = Net Income + (Interest Expense × (1 - Tax Rate)).
• Capital Invested = Total Assets - Current Liabilities.
• WACC = (Debt × Cost of Debt) + (Equity × Cost of Equity).
• ROI = Net Income / Total Assets.
• Residual Income = Net Income - (Capital Invested × WACC).
• Contribution Margin = Sales - Variable Costs.
• Contribution Margin Ratio = Contribution Margin / Sales.
• 'Fixed costs' are only fixed in the short run within a relevant range – outside that range, they can change.
• EVA is sensitive to changes in capital structure or market conditions.
• ROI does not consider the cost of capital.
