Break-Even Calculator
Calculate your break-even point by combining fixed costs, sales price, and variable costs. The calculator returns the units and revenue you need to cover every dollar of expense.
Break-Even Inputs
Keep variable costs lower than your price to stay profitable.
Units you must sell to cover fixed and variable costs without profit or loss.
How to Use This Calculator
Enter your fixed monthly (or annual normalized) costs, the price you charge per unit, and the variable cost that scales with each sale. The results refresh as soon as you click "Calculate" to show how many units and how much revenue are required before profit begins.
- Fixed costs are expenses that stay flat regardless of production volume (rent, leases, insurance, salaries).
- Sales price should reflect the average transaction, including any discounts handeled regularly.
- Variable costs include direct materials, hourly labor, or commissions tied directly to each unit sold.
Methodology
The calculator uses standard contribution-margin logic: subtract the variable cost per unit from the sales price to find the contribution margin, then divide total fixed costs by that margin. The result is rounded up to the next whole unit, reflecting how many complete sales are needed to cover every fixed dollar.
Why Use This Calculator?
- Instantly calculate the sales volume required to break even.
- Test pricing and cost scenarios to make proactive adjustments.
- Understand the core drivers behind profitability.
- Use the contribution margin insight to track risk and margin of safety.
