Purpose. Calculates the number of units and revenue needed to cover fixed costs, based on selling price and variable cost per unit.
Method overview. Unit break-even quantity is calculated as fixed costs ÷ contribution per unit, where contribution per unit equals selling price minus variable cost. If a contribution-margin ratio is used, break-even sales revenue is fixed costs ÷ contribution-margin ratio.
Worked example. With fixed costs of Rs. 500,000, a selling price of Rs. 2,000 and variable cost of Rs. 1,200 per unit, contribution is Rs. 800. The break-even quantity is 625 units. Every unit above that level contributes Rs. 800 toward profit before taxes and other excluded costs.
Interpretation. Break-even analysis assumes the selected prices and costs remain reasonably stable across the activity range. Capacity constraints, step-fixed costs, sales mix, discounts and taxes can shift the true break-even point.
How to use the result. Start with source data you can verify, enter values on a consistent unit and time basis, and record the assumptions used. The main inputs on this page include Total Fixed Costs (per period), Selling Price per Unit, Variable Cost per Unit, Your Name, Email, Company Name. Re-run the calculation when those assumptions change rather than carrying an old result forward.
Decision use. Use this tool for scenario planning and comparison rather than as a substitute for professional financial advice. Financial assumptions can change the result materially, so test more than one scenario instead of relying on a single output.
Limitations. Check the time period, rate convention, compounding assumption and cash-flow timing before interpreting the result. Small changes in rates or timing can have a large cumulative effect.
