Break even volume comes from the amount each sale contributes after its variable costs. Revenue alone cannot answer it. The Break Even Calculator separates that contribution from the fixed cost total and rounds the required sales up to whole units.
Give fixed and variable costs different jobs
Enter selling price PKR 1,000, variable cost PKR 600, percentage fee zero and fixed costs PKR 20,000 for the period. Each unit contributes PKR 400 towards those fixed costs. Dividing PKR 20,000 by PKR 400 gives 50 units.
At 50 sales, revenue is PKR 50,000 and variable cost is PKR 30,000. The PKR 20,000 remaining pays the entered fixed costs, leaving zero included profit. This is a volume threshold, not a prediction of demand.
Rounding up prevents a fractional target
Change fixed cost to PKR 20,100 while keeping the same contribution. The mathematical requirement is 50.25 units, so the result becomes 51 whole units. Those sales contribute PKR 20,400 and leave PKR 300 after fixed costs.
A rounded target can therefore show a small positive profit. That is expected: the smallest practical whole unit volume can sit just above the exact zero profit point.
Use costs from the same period
Monthly rent belongs with a monthly sales target. A one year salary total compared with one month’s expected orders describes a different question. State the period before entering fixed costs and keep that definition in exported records.
Costs that rise with every sale belong in variable cost. Packaging and per order delivery cannot be treated as fixed just because you pay their invoice once a month. Similarly, do not allocate the same rent into unit cost and then enter the full rent again under fixed costs.
No positive contribution means no finite solution
If price after the entered percentage fee does not exceed variable cost, additional units do not help pay the fixed bill. The tool rejects a nonpositive contribution rather than offering an enormous but meaningless break even quantity.
Actual selling capacity, stock and cash may still limit whether the target can be reached. Use Target Profit Sales Calculator to add a desired profit above break even, and Inventory Cash Gap Calculator to estimate funding under an entered operating cycle. Neither turns the calculated volume into guaranteed sales.
