This 4-in-1 Break Even Volume calculator helps you find the missing variable in your CVP analysis. Enter any three values—Fixed Costs, Price per Unit, Variable Cost, or Break-Even Volume—and we will solve for the fourth.

Break Even Volume Formula
Q = F / (P – V)
Solve for Fixed Costs (F):
F = Q * (P – V)
Solve for Price (P):
P = (F / Q) + V
Solve for Variable Cost (V):
V = P – (F / Q)
Formula Variables
- (Q) Break-Even Volume: The total number of units (volume) you must sell to have zero profit and zero loss.
- (F) Fixed Costs: All costs that remain the same regardless of your sales volume (e.g., rent, salaries, insurance).
- (P) Price per Unit: The retail price you charge for a single unit of your product.
- (V) Variable Cost per Unit: All costs directly associated with producing one unit (e.g., materials, direct labor, commissions).

What is Break Even Volume?
Break-Even Volume is the specific number of units a company must sell to cover all of its costs (both fixed and variable). At this sales volume, the company’s total revenue is exactly equal to its total costs, resulting in a net income of $0. It is a critical metric in business planning, often referred to as the “Break-Even Point” (BEP).
Understanding this volume is essential for any business, especially when seeking a business loan. It tells you the minimum level of sales required to be profitable. Any unit sold *above* the break-even volume contributes directly to profit, based on the “contribution margin” (Price – Variable Cost).
This calculation is a cornerstone of Cost-Volume-Profit (CVP) analysis. It helps business owners set prices, manage costs, and determine the sales volume needed to reach a target profit (by adding the target profit to the fixed costs in the formula).
How to Calculate Break Even Volume (Example)
-
Identify the Variables
Imagine a coffee shop with the following monthly finances:
• Fixed Costs (F): $5,000 (rent, salaries, utilities)
• Price per Cup (P): $4.00
• Variable Cost per Cup (V): $1.50 (beans, cup, milk)
We need to find the Break-Even Volume (Q). -
Choose the Correct Formula
To find the volume in units, we use the formula:
Q = F / (P – V) -
Calculate Contribution Margin
First, find the contribution margin, which is the profit per unit:
P – V = $4.00 – $1.50 = $2.50 per cup -
Calculate the Volume
Now, divide the fixed costs by the contribution margin:
Q = $5,000 / $2.50
Q = 2,000 units
The coffee shop must sell 2,000 cups of coffee per month to cover all costs.
Frequently Asked Questions (FAQ)
What is the difference between Break-Even Volume and Break-Even Point?
They are often used interchangeably. “Break-Even Volume” or “Break-Even Point in Units” specifically refers to the *number of units* (Q). The “Break-Even Point in Dollars” refers to the total sales revenue needed (which would be Q * P, or 2,000 * $4.00 = $8,000 in our example).
What is a “Contribution Margin”?
The contribution margin is the profit you make on a single unit *before* accounting for fixed costs. The formula is `Price per Unit (P) – Variable Cost per Unit (V)`. In our example, it was $2.50. This is the amount each sale “contributes” to paying off fixed costs.
Why can’t my Price be lower than my Variable Cost?
If your Price (P) is less than your Variable Cost (V), you lose money on every single unit you sell. This creates a negative contribution margin, and you will *never* be able to cover your fixed costs, no matter how many units you sell. You will only lose more money with each sale.
How can this calculator find my Fixed Costs?
If you know your target sales volume (Q), your price (P), and your variable costs (V), this calculator can work backward to tell you the maximum Fixed Costs (F) your business can support. This is useful for knowing how much you can afford in rent or salaries.
