What is break-even analysis used for?

Break-even analysis tells you the minimum volume of sales you need to cover all costs. It's essential for pricing decisions, launch planning, and understanding the impact of cost changes on your business viability.

Fixed vs variable costs

Fixed costs don't change with volume: rent, salaries, insurance, software subscriptions. Variable costs scale with production: materials, packaging, delivery fees, payment processing.
