Revenue = Units Sold × Selling Price per Unit
Total Variable Cost = Units Sold × Variable Cost per Unit
Contribution Margin = Revenue − Total Variable Cost
EBIT = Contribution Margin − Fixed Operating Costs
DOL = Contribution Margin ÷ EBIT
Break Even Units = Fixed Operating Costs ÷ Contribution per Unit
Break Even Sales = Fixed Operating Costs ÷ Contribution Margin Ratio
Estimated EBIT Change % = DOL × Sales Change %
Enter the number of units sold during the period.
Add the average selling price per unit.
Enter the variable cost attached to each unit.
Provide total fixed operating costs for the same period.
Optionally add an expected sales change percentage for scenario testing.
Optionally enter a tax rate to estimate after tax operating profit.

It measures how sensitive operating profit is to a change in sales. Higher leverage means profit can rise faster, but it can also fall faster when revenue declines.
A high DOL usually means fixed costs take a larger share of the cost structure. That amplifies profit growth during strong sales periods, but it also magnifies losses when sales weaken.
Contribution margin is the amount left after subtracting variable costs from revenue. It is the pool available to cover fixed costs and then generate operating profit.
DOL becomes undefined when EBIT is zero because the formula divides by operating profit. That usually happens at or very near the break even point.
Margin of safety shows how far current sales are above break even sales. A larger cushion means the business has more room before it starts losing money.
Leverage analysis usually focuses on EBIT before tax. The tax field here is optional and helps you extend the view to after tax operating profit for planning purposes.
Yes. Changing selling price or variable cost shifts contribution margin, break even sales, and leverage. That makes the tool useful for pricing, budgeting, and cost control reviews.
The chart helps you see where revenue crosses total cost and how EBIT responds across sales volumes. It makes leverage behavior easier to understand than raw numbers alone.
