Why Break-even Analysis Matters
A business can generate sales and still lose money when its contribution from each sale is not enough to cover rent, salaries, software, insurance, equipment, and other fixed costs. Break-even analysis connects pricing, cost structure, and sales volume in one simple planning model.
For a single product, the basic unit formula is fixed costs divided by contribution per unit, where contribution per unit equals selling price minus variable cost. The result is an estimate, not a guarantee, because demand, discounts, taxes, returns, capacity, product mix, and cash timing can change the real outcome.
How Hemiley Calculates the Break-even Point
Enter fixed costs for the selected period, the selling price per unit, and the variable cost per unit. Hemiley calculates contribution per unit and estimates the number of units required to cover the entered fixed costs.
Where supported, the calculator may also estimate break-even revenue. Use values from the same time period and define costs consistently. For a multi-product business, a simple single-product calculation may not reflect changing sales mix.

How to Calculate Break-even in 4 Steps
- 1
Choose one period.
Use monthly, quarterly, or annual values consistently.
- 2
Enter fixed costs.
Include costs that do not change directly with each unit sold for that period.
- 3
Enter price and variable cost.
Use the expected net selling price and the incremental cost per unit.
- 4
Review the result.
Compare break-even units with realistic capacity and demand, then test alternative scenarios.
Common Use Cases

Why Choose Hemiley?
Hemiley provides a focused break-even workflow that makes cost, price, contribution, and volume assumptions easy to compare.
The result is a planning estimate. It does not predict demand, replace cash-flow forecasting, value a business, account automatically for taxes, or model every product, capacity limit, financing cost, and timing difference.

Frequently Asked Questions
It is the sales level at which total revenue equals the costs included in the calculation, producing neither profit nor loss under those assumptions.
It is selling price per unit minus variable cost per unit. That contribution first covers fixed costs and then contributes to profit.
There is no positive contribution per unit, so increasing sales will not cover fixed costs under those inputs.
Yes. Monthly fixed costs should be compared with monthly sales assumptions, and annual fixed costs with annual assumptions.
A weighted-average contribution approach may be needed when products have different prices, costs, and sales shares. A single-product result may be misleading.
No. Credit terms, inventory purchases, loan payments, taxes, capital spending, and timing differences can make cash flow different from accounting break-even.
