Operating, Financial and Combined Leverage Analysis
Measure how sales, costs and financing magnify operating profit and financial results. Compute DOL, DFL and DCL, then examine how changes in fixed costs and interest load affect risk through scenarios and sensitivity analysis.
Measure how sales, costs and financing magnify operating profit and pretax earnings. Compute DOL, DFL and DCL, then stress fixed costs, debt and interest.
Leverage degrees are point elasticities at a given activity level. Near operating or interest break-even they can become very large. For large shocks, linear DOL/DFL/DCL forecasts can mislead; this tool therefore also recomputes the full income statement.

Notes on leverage analysis
What is the degree of operating leverage?
DOL is the approximate percentage change in EBIT for a 1% change in sales at the current volume, driven by fixed operating costs.
What is the degree of financial leverage?
DFL is the approximate percentage change in pretax profit (and, with a stable capital structure, EPS) for a 1% change in EBIT, driven by interest.
What is the degree of combined leverage?
DCL = DOL × DFL. It captures how a sales change is magnified first into EBIT and then into pretax earnings.
How do fixed costs affect DOL?
Higher fixed operating costs reduce EBIT for a given contribution and move the firm closer to break-even, which raises DOL.
How do debt and interest affect DFL?
More debt or a higher effective rate raises interest. With EBIT unchanged, EBT shrinks and DFL rises.
How is DOL related to the break-even point?
As volume approaches operating break-even, EBIT approaches zero and DOL becomes very large. Far above break-even, DOL typically declines.
How is DFL related to interest coverage?
Interest coverage = EBIT / interest. Coverage near 1× is the financial analogue of operating break-even: DFL becomes extremely large.
What are the limits of leverage ratios?
They are local elasticities. Large shocks should be read from a full recomputation, not from multiplying DOL or DCL by a large percentage.
Simplifying assumptions
- Price, unit variable cost and fixed operating costs are constant over the relevant range.
- Interest expense is treated as a fixed financing cost in the period.
- Negative EBT does not generate an automatic tax refund in this model.
- EPS comments assume an unchanged number of shares and capital structure.
- Leverage degrees are point measures, not forecasts for large moves.
