How to use this tool
Enter USD fixed costs for one period and per-unit price and variable cost. Price must exceed variable cost so each sale contributes toward recovering the fixed amount.
Results and examples
Units are fixed costs divided by contribution, rounded upward to a whole count. Break-even revenue uses that integer quantity and may sit slightly above the continuous zero-profit point.
Worked example
USD 100 fixed cost, USD 12 price and USD 5 variable cost requires ceiling(100/7), or fifteen units.
Limitations
- Product mix, tax, discounts and step costs are excluded.
- The form does not establish whether demand can support that volume.
