Break-even analysis is a fundamental tool in business planning that helps determine the point at which total revenue equals total costs. At this point, the business is neither making a profit nor incurring a loss. Understanding your break-even point is crucial for pricing decisions, cost control, and profitability planning.

What is Break-even Analysis?

Definition

Point where revenue equals costs
No profit, no loss
Critical for business planning
Risk assessment tool

Key Concepts

Fixed costs: Don't change with volume
Variable costs: Change with production
Contribution margin: Price minus variable cost
Safety margin: Sales above break-even

Break-even Formulas

Core Calculations

Essential break-even formulas

Break-even Units:

Units = Fixed Costs ÷ (Price - Variable Cost)
Also: Fixed Costs ÷ Contribution Margin per Unit
Minimum sales volume needed
Expressed in units

Break-even Revenue:

Revenue = Break-even Units × Selling Price
Also: Fixed Costs ÷ Contribution Margin Ratio
Minimum sales revenue needed
Expressed in dollars

Contribution Margin

Per Unit:

Selling Price - Variable Cost per Unit
Amount that contributes to fixed costs
Higher margin means lower break-even
Key profitability metric

Ratio:

Contribution Margin ÷ Selling Price
Percentage of revenue covering fixed costs
Used for break-even revenue calculation
Higher ratio improves profitability

Visual Break-even Analysis

Understanding the break-even relationship

Total Revenue Line:

Starts at origin (0,0)
Slope equals selling price
Rises with increased sales volume
45-degree angle for break-even

Total Cost Line:

Starts above origin (fixed costs)
Slope equals variable cost per unit
Intersection is break-even point
Area below is loss, above is profit

Margin of Safety

Definition:

Current sales minus break-even sales
Buffer against sales fluctuations
Expressed in units or dollars
Higher margin means lower risk

Formula:

Margin of Safety = Current Sales - Break-even Sales
Margin of Safety % = (Current Sales - Break-even Sales) ÷ Current Sales
Indicates business stability
Used for risk assessment
