Break-Even Calculator: Calculate Units and Revenue Target
Find how many units and total sales revenue your business needs to cover all costs.
How to Use This Break-Even Calculator
Enter your total periodic fixed expenses, anticipated product selling price, and variable cost per unit. The calculator instantly evaluates your unit economics and reports the exact sales targets required to eliminate operational losses:

- Fixed Costs: Enter aggregate monthly or annual overhead (office lease, baseline salaries, software subscriptions, insurance).
- Selling Price per Unit: Enter the gross unit price charged to customers before sales tax.
- Variable Cost per Unit: Enter per-unit production expenditures (materials, direct labor, packaging, payment processing fees).
- Break-Even Units: Displays the minimum unit sales required. Units are rounded up to the nearest integer because fractional product sales are not possible.
- Break-Even Revenue: The total gross revenue required to clear all fixed and variable overhead.
Fundamental Break-Even Formulas
Break-even analysis relies on standard cost-volume-profit (CVP) mathematics. The relationship between cost components is defined below:
Contribution Margin Ratio: CM Ratio = CM / Selling Price
Break-Even Volume (Units): Break-Even Units = Fixed Costs / CM
Break-Even Revenue: Break-Even Revenue = Break-Even Units × Selling Price = Fixed Costs / CM Ratio
Separating Fixed vs Variable Costs
Accurate break-even calculations depend on classifying expenses into fixed and variable categories. The table below illustrates standard cost distributions across typical business models:
| Business Model | Typical Fixed Costs | Typical Variable Costs |
|---|---|---|
| E-Commerce & Retail | Warehouse lease, Shopify/server hosting, base staff salaries | Inventory wholesale cost, pick and pack fees, shipping, 2.9% + 30¢ gateway fees |
| SaaS & Digital Services | Core engineering payroll, office space, standard tooling | Cloud hosting bandwidth per user, API query consumption, customer onboarding support |
| Manufacturing | Factory depreciation, plant manager salaries, equipment insurance | Raw materials (steel, plastic), hourly machine labor, packaging, freight logistics |
Worked Calculation Example
Consider a boutique apparel brand producing custom jackets with the following parameters:
- Monthly Fixed Costs: $50,000 (studio rent, utilities, core staff)
- Retail Selling Price: $200 per jacket
- Variable Production Cost: $120 per jacket (fabric, buttons, seamstress labor, shipping box)
Using the formulas above:
- Contribution Margin per Unit: $200 - $120 = $80. Every jacket sold delivers $80 toward paying down the $50,000 fixed overhead.
- Break-Even Units: $50,000 / $80 = 625 units. The company must sell exactly 625 jackets each month to achieve zero net loss.
- Break-Even Revenue: 625 × $200 = $125,000. Selling the 626th jacket produces the first dollar of genuine operating profit.
Break-Even Sensitivity: Three Strategic Levers
When break-even requirements appear unattainable relative to total market size, executive management can adjust three primary operational levers:
- Raise Prices: Increasing selling price directly expands unit contribution margin. If jacket price increases by 10% to $220, contribution margin rises to $100 ($220 - $120), slashing break-even demand from 625 units to 500 units (a 20% volume reduction).
- Lower Variable Expenses: Securing volume discounts on materials reduces variable cost. If fabric costs drop by $10 per unit, contribution margin expands to $90, lowering required volume to 556 units.
- Restructure Overhead: Downsizing non-essential fixed subscriptions or renegotiating lease terms directly reduces the numerator in the break-even equation.
Frequently Asked Questions
What is the break-even point in business?
The break-even point is the exact sales volume at which total revenue equals total costs (both fixed and variable). At this point, net profit is zero, meaning the business is neither losing money nor generating a surplus.
What is contribution margin per unit?
Contribution margin per unit is the selling price minus the variable cost per unit. It represents the dollar amount each unit sale contributes toward paying off overhead fixed costs before generating net profit.
What is the difference between fixed and variable costs?
Fixed costs remain constant regardless of production or sales volume, such as rent, executive salaries, and liability insurance. Variable costs fluctuate directly with production volume, such as raw materials, packaging, and credit card processing fees.
What does a negative contribution margin mean?
A negative contribution margin occurs when variable cost per unit exceeds the selling price. In this scenario, every unit sold increases the overall financial loss, making break-even mathematically impossible until prices rise or variable costs decrease.
Does break-even analysis account for taxes or depreciation?
Standard operational break-even analysis focuses on operating cash flow and excludes income taxes because zero taxable profit exists at the break-even point. Non-cash depreciation can be included in fixed costs if calculating an accounting break-even rather than a cash break-even.
What strategies effectively lower the break-even point?
Businesses can lower their break-even target by increasing selling prices, negotiating bulk supplier discounts to lower unit variable costs, or trimming fixed operational overhead.
