Break-Even Calculator: Find the Sales Needed to Cover Costs
Learn the break-even formula, fixed and variable costs, and how businesses estimate the sales needed to avoid a loss.
A Break-Even Calculator helps a business estimate the sales volume at which total revenue equals total costs. At this point, the business has neither a profit nor a loss before other factors not included in the model.
Break-Even Formula
Break-Even Units = Fixed Costs ├╖ (Selling Price per Unit тИТ Variable Cost per Unit)
The difference between selling price and variable cost is called contribution per unit. The formula is useful only when contribution is positive.
Example
Suppose monthly fixed costs are тВ╣60,000, a product sells for тВ╣500, and variable cost is тВ╣300 per unit. Contribution is тВ╣200 per unit, so break-even volume is тВ╣60,000 ├╖ тВ╣200 = 300 units. Selling more than 300 units may create an operating profit under these assumptions; selling fewer may leave a shortfall.
How to Use a Break-Even Calculator
- Enter fixed costs for the period.
- Enter selling price per unit.
- Enter variable cost per unit.
- Calculate the break-even units or sales revenue.
- Compare the result with realistic demand and production capacity.
Include the Right Costs
Fixed costs may include rent and salaries that do not change directly with each unit. Variable costs may include materials, packaging, and per-sale fees. Some costs are mixed, so estimates should reflect how they behave at different volumes.
Limitations
The basic model assumes prices and costs stay stable and that units sold can be estimated. Discounts, returns, taxes, capacity limits, and multiple products can change the result.
Use break-even analysis as a planning tool, and review assumptions regularly as your business changes.
