Contribution matters more than selling price alone
Only the amount left after variable unit cost can recover fixed costs. Counting the full selling price would understate the number of sales required.

Calculate units needed to break even on an event.
Estimate how many units must be sold to recover fixed event costs from selling price and per-unit cost. It is useful for convention merchandise, pop-ups and other small sales where you want a simple break-even quantity.
1,000 − 250 = 750 per unit. 30,000 ÷ 750 = 40, so the break-even point is 40 units and 40,000 of revenue.If payment fees, shipping, discounts, waste or other per-sale costs are not included in unit cost, the real break-even point will be higher than this result.
Only the amount left after variable unit cost can recover fixed costs. Counting the full selling price would understate the number of sales required.
A result such as 39.2 means 40 whole units must be sold, so break-even revenue can end up slightly above the exact fixed-cost amount.
Booth fees and venue charges usually belong in fixed cost; product manufacturing that increases with each sale belongs in unit cost.
If the goal is not merely zero profit but, for example, 30,000 profit, one simple scenario is to add that target to fixed costs and calculate again.
Tax treatment, inventory valuation and complex fee structures can require more detailed financial analysis than this three-input calculation.
