This is a simplified break-even analysis and excludes taxes, financing costs, and step changes in costs.
The calculator subtracts variable cost per unit from selling price to get contribution margin. Fixed costs divided by contribution margin gives break-even units; fixed costs divided by contribution margin ratio gives break-even sales.
Results depend on separating fixed and variable costs correctly. For real decisions, review costs such as rent, labor, payment fees, and shipping that may behave differently as sales volume changes.
