01
What is a break-even point?
The break-even point is the sales volume where revenue covers both fixed and variable costs. At that point, the business has no profit or loss under the assumptions entered.
It is a practical planning reference for testing a price, sales target, or cost structure. It is not a guarantee of results because actual sales and costs can change.
02
How to calculate the break-even point
First subtract variable cost per unit from selling price per unit. This gives contribution margin per unit. Divide fixed costs by that amount, then round up to the next whole unit.
Contribution Margin per Unit = Selling Price per Unit − Variable Cost per Unit
Break-even Units = Fixed Costs ÷ Contribution Margin per Unit, rounded up
Break-even Revenue = Rounded Break-even Units × Selling Price per Unit
Rounding up matters: the displayed whole-unit target must fully cover fixed costs rather than stop just short.
03
Fixed costs vs variable costs
Fixed costs do not change directly with the number of units sold during the planning period. Examples can include rent, insurance, software subscriptions, and base salaries.
Variable costs grow with sales volume. Materials, unit packaging, production labor paid per item, and per-sale fees may belong here. Keeping the two categories separate makes it clear which costs every sale must help cover.
04
What is contribution margin?
Contribution margin shows how much the sale of one unit adds toward covering fixed costs and, after fixed costs are covered, profit. A $50 selling price and $30 variable cost produce a $20 contribution margin per unit.
Break-even can be reached only when contribution margin is positive. The contribution margin ratio expresses the same amount as a percentage of selling price.
Use the Profit Margin Calculator to examine profit as a share of revenue, or compare cost-based pricing with the Markup Calculator.
05
Break-even point in units vs break-even revenue
Break-even units tells you the minimum whole-unit sales target. Break-even revenue translates that rounded target into sales value by multiplying it by selling price per unit.
This calculator bases revenue on the rounded-up unit count. That keeps the two displayed break-even results consistent and ensures the unit target covers the entered fixed costs.
06
How to calculate sales for a target profit
Target Profit mode adds desired operating profit to fixed costs. Contribution from sales must cover that combined amount, so the result answers how many units you need to sell to make the entered profit.
Target Profit Units = (Fixed Costs + Desired Profit) ÷ Contribution Margin per Unit
Target Profit Revenue = Whole Target Profit Units × Selling Price per Unit
The calculator shows the exact mathematical requirement and rounds up separately for a practical whole-unit target. The Pricing Calculator can help work backward from costs and a margin goal when price is the unknown instead.
07
Break-even vs target profit
Break-even sets profit to zero: contribution only needs to cover fixed costs. Target profit includes a positive goal, so it requires additional units and revenue above break-even.
- Contribution Margin per Unit: $50 − $30 = $20.
- Break-even Units: $50,000 ÷ $20 = 2,500 units.
- Break-even Revenue: 2,500 × $50 = $125,000.
- Units for a $10,000 target profit: ($50,000 + $10,000) ÷ $20 = 3,000 units.
- Additional volume: 3,000 − 2,500 = 500 units, or $25,000 in additional revenue.
08
What happens when variable cost is higher than selling price?
When variable cost equals or exceeds selling price, contribution margin is zero or negative. Selling more units then adds nothing toward fixed costs or increases the loss, so no break-even point exists in this model.
Break-even and target-profit results show N/A until selling price is higher than variable cost per unit. Sensitivity cells that cross this boundary are marked Not viable rather than showing a fake zero, Infinity, or negative unit target.
The estimate assumes one constant price and unit cost. It does not model discounts, taxes, step costs, changes in price, or cost changes at different volumes.
09
Price and variable cost sensitivity
A higher price usually lowers required units when variable cost stays constant. A higher variable cost usually raises required units because less contribution remains from every sale.
Small changes can have a large effect when contribution margin is narrow. The matrix compares both inputs at −10%, −5%, base, +5%, and +10% using the same engine as the main result. It is a scenario view, not a demand forecast or categorical pricing recommendation.

Frequently asked questions
What is the break-even point?
The break-even point is the sales volume where total revenue equals total fixed and variable costs. At that point, the calculation shows neither a profit nor a loss.
How do I calculate break-even units?
Subtract variable cost per unit from selling price per unit to find contribution margin per unit. Then divide fixed costs by that contribution margin.
What is contribution margin?
Contribution margin per unit is selling price per unit minus variable cost per unit. Each unit's contribution first covers fixed costs and then supports operating profit.
How do I calculate sales needed for a target profit?
Add desired profit to fixed costs, divide that total by contribution margin per unit, and round up when only whole units can be sold. Multiply the whole-unit result by selling price to get practical required revenue.
What happens if variable cost is higher than selling price?
Contribution margin becomes zero or negative, so selling more units cannot cover fixed costs or reach a positive profit target under those assumptions. A higher price or lower variable cost is needed for a finite result.
Does a higher selling price lower break-even?
Usually, yes, when variable cost and fixed costs stay constant. A higher price increases contribution per unit, so fewer units are mathematically required, though the calculator does not predict how demand may respond.
What is the difference between break-even and target profit?
Break-even is the point where profit is zero. Target profit adds a desired operating-profit amount to fixed costs and finds the higher unit and revenue threshold needed to cover both.
