Total Revenue is the total amount of incoming funds a business receives from sales, services, investments and other sources. It is a key performance indicator used to gauge the financial health and success of a company, as well as a good way to track changes in revenue over time. While it may sound straightforward, successfully calculating total revenue requires an understanding of how to account for all incoming money, including sales taxes, discounts, returns and more. A comprehensive knowledge of accounting and financial concepts can help ensure your total revenue figures are accurate – and that you are getting a clear picture of your business’s overall performance.
