Worked example
With ₹10,000 fixed costs and ₹100 contribution per unit, break-even volume is 100 units. Use this example as a reference for the type of calculation, not as a prediction of your own outcome.
Formula and calculation method
Break-even units = fixed costs / (selling price per unit − variable cost per unit). Results can be rounded for display, so small differences may arise when comparing with another tool.
Contribution margin per unit
Break-even analysis starts with the amount each unit contributes after variable cost. If a product sells for 250 and variable cost is 150, contribution is 100 per unit. Fixed costs of 10,000 would then require 100 units to break even under this simplified model.
How to use break-even planning
Use the estimate to test pricing, supplier costs, and sales targets. A small reduction in contribution per unit can substantially increase the units needed to cover fixed expenses. Compare multiple realistic scenarios rather than assuming every unit will sell at the same price.
Assumptions and limitations
The basic formula assumes fixed costs stay constant within the relevant activity range and variable cost per unit does not change. Returns, discounts, taxes, mixed products, and capacity limits can change the real result. When contribution is zero or negative, increasing sales alone will not cover fixed costs.
Contribution per unit
Subtract variable cost per unit from selling price to find the amount available to cover fixed costs. A zero or negative contribution cannot cover fixed costs through additional sales.
Fixed and variable costs
Rent may be fixed over a period, while materials or packaging may vary with each unit. Classify costs consistently before calculating.
Practical sales targets
Break-even units are a minimum estimate under simplified assumptions. Add a margin for returns, discounts and unexpected costs when setting a business target.
Frequently Asked Questions
What if contribution per unit is zero?
Break-even cannot be reached at a non-positive contribution margin under this model.
Important: This tool is intended for general information and estimation. Verify important financial, health, tax, or legal decisions using official documentation or qualified professional advice.
What the break-even point means
The break-even point is the level of sales at which estimated total revenue covers estimated total costs. It depends on fixed costs and the contribution left from each sale after variable costs.
If the selling price is no greater than the variable cost per unit, additional unit sales may not cover fixed costs. Check whether your assumptions reflect discounts, returns, and changing costs.
Does break-even mean the business earns a profit?
No. At break-even, estimated profit is zero before any costs omitted from the model.
