Break-Even Point Calculator (Units, Sales Revenue & Margin)
Determine the exact unit volume and revenue required to cover fixed operating costs and reach profitability.
You must sell at least 200 units to cover all fixed costs. Every unit sold past this threshold generates pure net profit.
Amount remaining from each unit sold ($120 - $45) that contributes toward paying fixed overhead.
Percentage of each sales dollar that contributes directly to recovering overhead and generating profit.
Break-Even Point & Contribution Margin Guide (2026)
How to calculate unit break-even volume, gross dollar sales targets, fixed overhead allocation, and margin of safety.
The Break-Even Point is the exact sales milestone where total company revenue equals total expenses, yielding exactly $0 in profit and $0 in loss. Unit break-even is calculated as: Fixed Overhead Costs ÷ Contribution Margin Per Unit, where Contribution Margin equals Unit Sale Price − Variable Cost Per Unit. Every unit sold past the break-even volume produces pure pre-tax operating profit.
Fixed Costs vs. Variable Costs: The Essential Distinction
A successful Cost-Volume-Profit (CVP) calculation requires properly segregating expenses:
- Fixed Overhead Costs: Expenses incurred regardless of output volume, including commercial office lease, full-time administrative payroll, property insurance, and recurring SaaS software subscriptions.
- Variable Unit Costs: Expenses directly tied to production and fulfillment, including raw materials, packaging, direct assembly labor, shipping freight, and payment processor transaction fees.
Data Table: Break-Even Units Across Overhead and Unit Margins
| Monthly Fixed Overhead | Unit Price | Variable Cost | Contribution Margin | Break-Even Units | Break-Even Revenue |
|---|---|---|---|---|---|
| $5,000 / mo | $50.00 | $20.00 | $30.00 (60%) | 167 units | $8,350.00 |
| $15,000 / mo | $100.00 | $40.00 | $60.00 (60%) | 250 units | $25,000.00 |
| $30,000 / mo | $250.00 | $100.00 | $150.00 (60%) | 200 units | $50,000.00 |
Margin of Safety (MOS): Risk Protection Metric
The Margin of Safety quantifies how much current sales can decline before the business begins operating at a cash loss: ((Actual Sales − Break-Even Sales) ÷ Actual Sales) × 100. A healthy business targets a Margin of Safety above 25% to withstand economic recessions, seasonal dips, or supplier price increases.

Mathematical Formula & Calculation Logic
Every unit sold provides a Contribution Margin (Price - Variable Cost) that pays down fixed costs. Once cumulative contribution margin equals fixed overhead, the business breaks even.
