The **Break-Even Point Calculator** determines the exact sales quantity or revenue required to cover all fixed and variable costs, resulting in zero net income. This tool is fundamental for pricing and profitability analysis. **Input any three of the four core variables** (Fixed Costs F, Price P, Variable Cost V, or Quantity Q) to instantly solve for the missing one.

Break-Even Point Formulas
The core calculation is based on the Cost-Volume-Profit (CVP) relationship, which states that total revenue must equal total costs at the break-even point. We derive four formulas to solve for any missing component:

Variables Explained
These four variables are key to CVP analysis and profit planning:
- F (Fixed Costs): Costs that do not change with production volume (e.g., rent, salaries, insurance).
- P (Selling Price): The revenue generated from selling one unit of the product.
- V (Variable Cost): Costs that fluctuate directly with production volume (e.g., raw materials, direct labor).
- Q (Quantity): The number of units produced and sold to reach break-even.

What is the Break-Even Point (BEP)?
The **Break-Even Point (BEP)** is the production or sales level at which total revenues equal total expenses. In practical terms, this is the point where a business neither makes a profit nor incurs a loss. Determining the BEP is a crucial step in budgeting, pricing, and business planning because it helps managers understand the minimum level of activity required to avoid financial losses.
The calculation relies on distinguishing between **Fixed Costs** (F) and **Variable Costs** (V). The core concept is the **Contribution Margin** (\(P – V\)), which is the revenue per unit that contributes to covering the fixed costs. The BEP is reached when the total contribution margin generated from sales exactly equals the fixed costs. Analyzing this point allows businesses to set realistic sales targets and make informed decisions about scaling operations.
How to Calculate the Break-Even Quantity (Example)
-
Identify the Costs:
Assume **Fixed Costs (F)** are **\$20,000**. The **Selling Price (P)** is **\$50** per unit, and the **Variable Cost (V)** is **\$30** per unit.
-
Calculate Contribution Margin:
The contribution margin is $P – V$: $\$50 – \$30 = \mathbf{\$20}$ per unit.
-
Apply the BEP Formula:
Divide Fixed Costs by the Contribution Margin to find the quantity (Q): $$ Q = \frac{F}{P – V} = \frac{\$20,000}{\$20} $$
-
Determine the Break-Even Quantity:
The resulting Break-Even Quantity is **1,000 units**. The company must sell 1,000 units to cover all costs.
Frequently Asked Questions (FAQ)
A: BEP in Units (Q) tells you the physical quantity of products you must sell. BEP in Sales Dollars tells you the total revenue ($\text{Revenue} = P \times Q$) you must achieve. The sales dollar BEP is useful for multi-product companies.
A: The contribution margin is the amount of revenue left over after covering variable costs. It represents the fund available to pay off fixed costs and eventually generate profit. If the contribution margin is negative, the business can never break even.
A: If fixed costs (F) increase and all other variables remain constant, the break-even point (Q) will increase. This means the business must sell more units to cover the higher fixed expenses.
A: Yes, conceptually. To solve for a Target Quantity ($Q_{Target}$), you modify the formula: $Q_{Target} = \frac{\text{Fixed Costs} + \text{Target Profit}}{P – V}$. This is handled by a dedicated Target Profit Calculator.
