Fixed Costs
Costs that usually stay the same within the decision range, such as rent, salaried labour, insurance, software subscriptions, equipment leases, and committed overheads.
Break-Even Analysis
Calculate the sales volume needed to cover fixed and variable costs, then review target profit volume, margin of safety, and profit behaviour.

Enter fixed cost, selling price, variable cost, expected sales, and target profit.

Variable Costs
Costs that change with each unit sold, such as materials, packaging, direct labour per unit, payment fees, shipping per order, sales commission, or unit-level outsourcing cost.
What to Exclude or Treat Carefully
Exclude sunk costs already spent. Treat one-off setup costs, stepped labour, taxes, financing, and mixed overheads carefully because they may need a separate scenario.
About Break-Even Analysis
Break-even analysis estimates the sales volume needed for total revenue to equal total cost. It helps teams understand whether pricing, cost structure, and expected demand can support a viable business decision.
The method is useful for product launches, service pricing, cost planning, capacity decisions, and quick financial viability checks before deeper analysis.
How to Use This Tool
- Enter total fixed costs for the period or decision being reviewed.
- Enter the selling price and variable cost per unit.
- Enter expected sales units to calculate margin of safety.
- Enter a target profit to estimate the units needed for that profit level.
- Review the result cards, interactive chart, and interpretation.
Methodology, Assumptions, and Limitations
Formula Logic
Notation
FC = fixed costs, P = selling price per unit, VC = variable cost per unit
Contribution margin per unit
CM = P - VC
Break-even units
QBE = FC / (P - VC)
Break-even revenue
RBE = QBE × P
Target profit units
QTarget = (FC + Target Profit) / (P - VC)
Required Inputs
The model requires fixed costs, selling price per unit, variable cost per unit, expected sales units, and optional target profit.
Assumptions
The calculation assumes a constant selling price, constant variable cost per unit, and fixed costs that do not change across the relevant volume range.
Limitations
Break-even analysis does not capture demand uncertainty, stepped fixed costs, capacity limits, product mix changes, taxes, financing, or cash-flow timing.
Strategies to Improve Your Break-Even Point
Increase Contribution Margin
Review pricing, discounts, product mix, and value-added bundles. Even a small price increase can reduce the units needed to break even when demand remains stable.
Reduce Variable Cost per Unit
Negotiate supplier costs, reduce scrap, improve labour efficiency, optimize packaging, or reduce per-order fulfilment costs.
Control Fixed Costs
Review subscriptions, rent, salaried capacity, equipment commitments, and overheads. Lower fixed costs reduce the starting cost base that sales must recover.
Test Practical Scenarios
Compare conservative, expected, and optimistic cases. Break-even analysis is most useful when it supports a range of decision scenarios rather than one fixed answer.
FAQ
What does break-even quantity mean?
It is the number of units that must be sold for total revenue to equal total cost, before profit begins.
What if variable cost is higher than price?
The model cannot produce a viable break-even quantity because each unit loses money before fixed costs are considered.
What is margin of safety?
Margin of safety compares expected sales to break-even sales. A higher value means expected demand is further above the break-even point.
