About Break-Even Calculator
Break-Even Calculator finds the sales volume at which revenue covers fixed and variable costs — the point where profit is zero and every additional unit starts contributing.
It also shows the margin of safety: how far sales can fall before the business starts losing money.

Questions about Break-Even Calculator
What is the formula?
Break-even units = fixed costs / (price − variable cost per unit). The denominator is the contribution margin.
Units or revenue?
Both are shown: units are actionable for production, revenue for planning.
How do I handle multiple products?
Use a weighted average contribution margin across the product mix, or calculate per product line.
Does it include taxes?
No. It is a pre-tax operating break-even; tax applies to profit above this point.
