Break-Even Calculator Free Online Estimate for Startup

How to use this Break-Even Calculator

Begin with the period you want to analyze, such as one month, one quarter or one production run. Add fixed costs that belong to that same period, including rent, salaried labor, insurance, subscriptions and other overhead that does not change directly with each unit sold.

Keep every input within the same reporting period. Compare the result with the main Break-Even Calculator before changing price, advertising, fees or volume.

Important assumptions

Break-even occurs when total revenue equals total fixed and variable costs. A positive contribution per unit is required.

Contribution per unit = Selling price − Variable cost per unit

Break-even units = Fixed costs ÷ Contribution per unit

Break-even revenue = Break-even units × Selling price

Contribution margin = Contribution per unit ÷ Selling price × 100
