What is a business break-even point?
This business break-even calculator helps you find the sales units needed to cover your fixed costs.
The break-even point is the sales level at which contribution covers fixed costs in a defined period. Below it, the business has a modeled operating shortfall. Above it, additional contribution can create operating profit, provided the cost assumptions remain valid.
Choose a meaningful period
Monthly fixed costs require a monthly sales target. Mixing annual overhead with a monthly unit forecast creates a misleading result even when the arithmetic is correct.
How to use the break-even calculator
Enter fixed costs, net price per unit, variable unit cost, and any percentage selling fee not already included. Add a profit target if you want to plan beyond simply covering costs.
Keep cost behavior consistent
Rent may be fixed within current capacity, but a larger sales plan could require another location or shift. When costs step up, rerun the model with the higher fixed-cost base instead of extrapolating the old result.
Step-by-step planning checklist
- Start with one month, quarter, or year.
- List the fixed costs for that period, then separate the costs that increase with each sale.
- After calculating, compare the required units with both customer demand and your available capacity.
- Test a lower selling price or higher unit cost to see how much room the plan has.
Formula and worked example
With $20,000 in fixed costs, a $100 price, $60 variable cost, and 3% selling fees, contribution is $37 per unit. Covering fixed costs requires 541 whole units, or $54,100 revenue. Reaching a $5,000 profit target requires 676 units and produces $5,012 of modeled profit.
Why the target is slightly exceeded
Whole units round upward. The extra $12 in the example is a rounding effect, not a separate source of income.
Use break-even as a planning check
Compare the required volume with realistic customer demand and delivery capacity. If the target is implausible, test pricing, costs, or the operating model. A low break-even point is only useful if customers will buy the product at the assumed price.
What the result does not forecast
The model does not predict demand, cash collection, inventory funding, taxes, or financing. A business can reach accounting break-even while still needing working capital. Multiple products require a stable sales-mix model rather than an arbitrary average unit.

Frequently asked questions
Does break-even mean I have enough cash?
No. Inventory purchases and customer payment timing can create cash needs even when modeled operating profit is zero.
Build a separate cash forecast for inventory payments, customer collections, and loan obligations. A profitable sale may be collected after its costs must be paid.
What if contribution per unit is negative?
The calculator flags the model because additional sales do not help cover fixed costs under those assumptions.
Review price, discounts, and variable costs before increasing sales. At zero contribution, sales add nothing toward fixed costs; below zero, more sales increase the modeled shortfall.
Why round sales units upward?
A business selling whole units cannot rely on a fractional unit to cover the remaining cost.
For example, a calculated requirement of 540.54 units becomes 541. Revenue shown at break-even uses that rounded whole-unit count.
Can I calculate a target profit?
Yes. The target-profit output adds your profit goal to fixed costs before dividing by contribution.
Enter a profit goal for the same period as your fixed costs. The output is modeled operating profit after the costs entered, not after-tax income.
Can I use this for many products?
Use separate models or a justified, stable composite sales unit. A changing mix can materially change break-even volume.
If your mix changes from higher-contribution to lower-contribution products, the required volume can rise even when total sales revenue looks similar.
