Understand the number before the decision
Divide period fixed costs by unit contribution and round the unit count up. With fixed costs of 300 and contribution of 15.50, you need 20 units. Revenue at that point is 800 and the amount remaining after variable and fixed costs is 10. These are example numbers, not a sales forecast.
For monthly break-even, enter monthly rent, subscriptions and fixed payroll. Do not mix an annual cost with monthly expenses without allocating it. Unit shipping, packaging and fees belong in variable costs, so do not include them again in fixed costs. The period is your choice; the tool does not assume one.
The result represents one product or an average unit reflecting your sales mix. If product margins differ substantially, calculate each product and use a contribution average weighted by actual sales volume. With non-positive unit contribution, the tool reports no break-even rather than performing an invalid division.
Price and costs are per unit. Fees are a percentage of the sale amount plus a fixed per-unit fee. Exclude recoverable sales tax from both price and cost so it is not counted as profit. Add advertising or return allowances to unit cost if needed. Numbers round for display only, except suggested price and break-even units, which round up. Currency is a label only. No exchange rates, preset provider fees or input uploads are used.
