How to Read Your Results
Break-even units show the estimated sales volume required before profit begins, based on average inputs.
Break-even revenue is the corresponding sales amount, not an additional amount on top of unit sales.
A positive expected profit means expected contribution is greater than fixed costs.
A negative sales gap means expected unit sales are below the estimated break-even volume.
For indivisible products or jobs, use the next whole unit above the calculated break-even result.
Assumptions & Important Notes
- Each example uses a single average selling price and variable cost.
- Fixed costs are treated as constant for the month.
- Taxes, financing costs, and unrecorded costs are excluded.
- Sales are assumed to be collected and fulfilled within the period for illustration.

Frequently Asked Questions
Can I use break-even examples for services instead of physical products?
Yes. One unit can represent a billable job, appointment, contract, or service sale, provided the price and direct cost are reasonable averages.
Why do some examples round break-even sales up?
A mathematical break-even result can include fractions. A business generally needs to sell the next full product or complete the next job to cover all costs.
What does a negative expected monthly profit mean?
It means the contribution from expected sales is lower than the monthly fixed costs entered in the calculation.
Can a business have high revenue but still be below break-even?
Yes. If variable costs consume a large portion of each sale, high revenue may still leave too little contribution to cover fixed costs.
