1. Operating, Financial, and Total Leverage Mechanics
Leverage measures how sensitive a company’s financial performance is to changes in its sales volume.
- Degree of Operating Leverage (DOL): Measures the percentage change in Operating Income (EBIT) resulting from a percentage change in revenue. It highlights how much a firm relies on fixed production costs (like factory leases and automated machinery) versus variable costs:
DOL = (%ΔEBIT) / (%ΔSales) = [ Q(P − V) ] / [ Q(P − V) − F ]
Where Q = quantity, P = price per unit, V = variable cost per unit, and F = fixed operating costs.
- Degree of Financial Leverage (DFL): Measures the percentage change in Earnings Per Share (EPS) relative to a percentage change in operating income. It isolates the impact of fixed financing costs, such as interest expense:
DFL = (%ΔEPS) / (%ΔEBIT) = EBIT / (EBIT − I)
Where I is total fixed interest expense.
- Degree of Total Leverage (DTL): Combines both operating and financial leverage to show the total sensitivity of EPS to changes in sales volume:
DTL = DOL × DFL = (%ΔEPS) / (%ΔSales) = [ Q(P − V) ] / [ Q(P − V) − F − I ]
2. Accounting vs. Financial Break-Even Analysis
- Accounting Break-Even Point: The sales volume where Net Income equals exactly zero. It treats depreciation as a standard operating cost:
Q_accounting = (Fixed Operating Costs + Depreciation) / (Price − Variable Cost) - Financial Break-Even Point: The sales volume where the project’s Net Present Value (NPV) equals exactly zero. This metric is more useful for capital budgeting decisions because it accounts for the opportunity cost of capital.
