METHOD & GUIDANCE
How this calculation works
Keep every input on the same time basis—for example, one month or one financial year—and do not mix cash figures with accrual figures. Tool IQ recalculates every output immediately; nothing you enter is saved or sent to us.
How to use the result
Translate break-even units into weekly or daily targets, then add the profit required above break-even rather than treating zero profit as the goal.
Worked example
The example has 3,500 of fixed cost and 45 contribution per unit. Rounding up, 78 unit sales are required to cover fixed costs.
Common mistakes
- Classifying a per-sale cost as fixed.
- Using average selling price without considering product mix.
- Ignoring capacity limits at the calculated volume.
Frequently asked questions
Is the break-even calculator free?
Yes. It requires no account and stores no calculation inputs.
Can I use the answer for a formal filing?
No. It is a planning estimate, not accounting, tax, legal or investment advice. Confirm material decisions with a qualified professional.
Which period should I use?
Keep every input on the same basis—for example, one month or one financial year. Use current figures first, then save a cautious scenario for comparison.
Why does the answer round up to a whole unit?
A fraction of a sale usually cannot cover the remaining fixed cost. The displayed unit target rounds up so contribution is at least equal to fixed costs.
Is break-even a sufficient sales target?
No. Break-even produces zero operating profit under the assumptions. Add the required profit, tax reserve and cash buffer before setting a practical target.
