Break-Even Point Calculator

Calculate the number of units you must sell at a given price to cover all of your costs — the moment a business starts generating profit instead of losing money on each transaction. Enter your total fixed costs (rent, salaries, software, insurance), your variable cost per unit (raw materials, packaging, payment processing), and your selling price per unit, and the calculator returns the break-even quantity. This is one of the most important numbers in starting or pricing any product: it tells you whether the business model is even viable, how much volume you need, and how sensitive profitability is to price and cost changes.
