Break-even analysis is a financial tool used to determine the level of output or sales at which total revenue equals total cost, i.e., no profit, no loss.
\text{Break-even point (units)} = \frac{\text{Fixed Cost}}{\text{Selling Price per Unit} - \text{Variable Cost per Unit}}

? Break-Even Analysis – In Detail
? Meaning:
Break-even analysis helps a business identify the point where its revenues cover all fixed and variable costs. Beyond this point, the company starts earning a profit.
> It’s widely used in cost control, pricing decisions, budgeting, and financial planning.
---
? Assumptions of Break-Even Analysis:
1. Costs are categorized into fixed and variable.
2. Selling price per unit remains constant.
3. Variable cost per unit remains constant.
4. Production = Sales (no inventory change).
5. Only one product or constant sales mix.
6. Costs and revenue are linear over the relevant range.
---
? Break-Even Point (BEP):
The point where:
\text{Total Revenue} = \text{Total Cost}
At BEP, the firm makes neither profit nor loss.
In units:
\text{BEP} = \frac{FC}{SP - VC}
FC = Fixed Cost
SP = Selling Price
VC = Variable Cost per unit

? Techniques of Break-Even Analysis:
1. Graphical Method (Break-Even Chart) – Plots total cost and total revenue on a graph.
2. Algebraic Method – Uses formulas to calculate BEP.
3. Contribution Margin Method – Focuses on profit per unit.
4. Cash Break-Even Analysis – Only considers cash-based costs and revenue.
5. Multi-product Break-Even – Used when multiple products are sold.
---
? Uses of Break-Even Analysis:
Helps determine minimum sales target to avoid losses.
Aids in pricing decisions and cost control.
Useful in investment planning and profit planning.
Assists in evaluating impact of changes in cost or price.
---
? Limitations of Break-Even Analysis:
1. Assumes constant costs and prices, which is not realistic.
2. Ignores changes in inventory levels.
3. Not effective for multi-product firms without constant sales mix.
4. Based on linear relationships, whereas real-world data is often nonlinear.
5. Fails to consider external factors like market conditions, inflation, and competition.
---
? Practical Unit of Break-Even Analysis:
Usually measured in units of product, sales revenue, or capacity utilization (%).
Can be monthly, quarterly, or yearly based on decision context.

✅ Conclusion
Break-even analysis is a simple yet powerful tool that helps businesses identify how much they must sell to cover costs and start earning profits. While it has limitations due to its assumptions, it remains a foundational element in managerial economics, especially for cost-volume-profit (CVP) analysis, budgeting, and strategic planning.
