What is break-even analysis?
Generally, Break-even analysis is a financial tool used by businesses to determine the point at which total revenue received equals total costs (fixed and variable costs). It helps to identify the minimum amount of sales needed to cover all costs and begin generating a profit.
This analysis is usually conducted to determine if a business should move forward with a project, launch a new product or service, or make changes to its pricing or cost structure.
