This Breakeven Point Calculator is a specialized variable solver that determines the financial threshold where total revenue equals total costs. By inputting any three of the four core variables—Fixed Costs, Unit Price, Variable Cost, or Breakeven Quantity—it accurately calculates the missing value.

Calculation Details
Breakeven Point Formula
The core relationship for the Breakeven Point is:
Profit = (Unit Price - Variable Cost) × Quantity - Fixed Costs
At the breakeven point, Profit = 0, which gives the fundamental BEP equation:
Breakeven Quantity (Q) = Fixed Costs (F) / (Unit Price (P) - Variable Cost (V))

Variables Explained
The calculator uses four core variables. You must enter values for three to solve for the missing one.
- Fixed Costs ($F$): Costs that do not change with the production volume (e.g., rent, salaries, insurance).
- Unit Price ($P$): The selling price per unit of the product or service.
- Variable Cost per Unit ($V$): Costs that fluctuate directly with the production volume (e.g., raw materials, direct labor).
- Breakeven Quantity ($Q$): The number of units that must be sold to cover all costs (where Profit is zero).

What is the Breakeven Point (BEP)?
The Breakeven Point (BEP) is the production level at which total revenues equal total expenses. In accounting terms, it signifies the point where a company or project generates zero profit. Understanding the BEP is critical for new businesses deciding on pricing strategies or for established companies launching new products, as it defines the minimum sales required to avoid a loss.
Analyzing the BEP involves identifying fixed costs and variable costs. Fixed costs are constant regardless of output, while variable costs change proportionally with production volume. The difference between the unit price and the variable cost is known as the “Contribution Margin,” which directly contributes to covering fixed costs.
The BEP is a fundamental tool in managerial accounting and financial planning. It helps managers determine production capacity, assess the impact of cost changes, and set realistic sales targets. A lower breakeven point generally indicates a healthier, less risky business model.
How to Calculate Breakeven Quantity (Example)
Assume a small company has $F$ = $40,000 in Fixed Costs, a $P$ = $100 Unit Price, and $V$ = $60 Variable Cost per Unit. Here is how to find the Breakeven Quantity ($Q$):
- Determine the Contribution Margin ($M$): Subtract the Variable Cost from the Unit Price. $$\text{CM} = P – V = \$100 – \$60 = \$40$$
- Apply the BEP Formula: Divide the Fixed Costs by the Contribution Margin. $$Q = \frac{F}{\text{CM}} = \frac{\$40,000}{\$40}$$
- Calculate the Result: The result is the Breakeven Quantity. $$Q = 1,000 \text{ units}$$
The company must sell 1,000 units to cover all costs.
Frequently Asked Questions (FAQ)
What happens if the Contribution Margin is negative?
If the Unit Price is less than the Variable Cost, the Contribution Margin (P – V) is negative. This means the business is losing money on every unit sold before even covering fixed costs, making a breakeven point mathematically impossible to reach in a positive number of units. The calculator will flag this as an error.
Is the Breakeven Point different for services?
No, the core principle is the same. For services, “Fixed Costs” might include office overhead and salaries, and “Variable Cost per Unit” might include direct labor hours or specialized materials needed for a single service client.
Can I use this calculator to solve for Fixed Costs?
Yes. If you input the Unit Price, Variable Cost, and a target Quantity, the calculator will solve for the Fixed Costs required to break even at that quantity.
Why is it important to check for consistency when all four variables are entered?
When all four values are entered, the calculator checks if the relationship $Q \times (P – V) = F$ holds true. If the result is not zero (within a small tolerance), it indicates that the inputs are inconsistent and an actual breakeven point has not been reached at the stated quantity.
