Frequently Asked Questions
What inputs do I need?
Three main inputs: fixed costs (rent, salaries, equipment), variable cost per unit (materials, labor per unit), and selling price per unit. The calculator computes break-even in both units and revenue.
What is the sensitivity slider?
There is no slider — type a new selling price into the price field (or try a preset) to answer 'what if I raise/lower my price?' Each edit recomputes instantly.
Does it show profit above break-even?
It shows break-even units, break-even sales, contribution margin, and CM ratio — no profit-at-volume table. To model a volume above break-even, multiply your units by the shown contribution margin.
Can I use this for service businesses?
Yes. Enter your monthly fixed costs and set variable cost to zero (or per-client cost). The break-even point shows how many clients or projects you need to cover costs.
Show me a break-even example with numbers?
Fixed costs $10,000, price $50, variable cost $30: contribution is $20 per unit, so break-even is 10,000 ÷ 20 = 500 units. Sell unit 501 onward and every $20 is profit.
When using Break-Even Calculator, is my financial data stored?
No. All calculations run locally in your browser. No cost or pricing data is transmitted.
