The estimate shows a $35,000 operating loss because the forecast volume is below the 4,400-unit break-even point.
How to Read Your Results
Annual revenue is total sales before deducting the costs included in the calculator.
Contribution margin shows the percentage of each sale left after variable cost per unit.
A positive operating profit means estimated revenue exceeds the included annual costs.
A negative operating profit means the estimated annual sales volume or margin does not cover those costs.
For practical whole-unit planning, round a fractional break-even result up to the next complete unit.
Compare forecast units with break-even units to see the estimated volume buffer.
Assumptions & Important Notes
- All input values cover the same annual period.
- Selling price is an average net amount per unit.
- Variable costs rise proportionately with units sold.
- No tax, financing, depreciation or cash-flow timing adjustments are included.

Frequently Asked Questions
How many annual unit economics examples should I compare?
Comparing a base case with at least one lower-volume or lower-margin case can help show how sensitive the estimate is to changes.
Why do two businesses with the same revenue have different operating profit?
Their variable costs, fixed costs, other annual costs and sales mix may differ, changing both contribution and total costs.
Should break-even units be rounded up?
For planning whole units, a fractional break-even result is usually rounded up because a partial unit may not be sellable.
What does a small gap above break-even mean?
It means a modest decline in sales volume, selling price, or contribution per unit could change the estimated profit result.
