Sales Revenue is the total income generated from sales of goods or services over a period of time. It’s calculated by multiplying the unit price of each product sold by the number of units sold, then adding all the results together. So if you sell 10 widgets at $1 each, your sales revenue would be $10. Understanding and keeping tabs on your business’ sales revenue is an essential part of running a successful company. Through studying it, you can gain insights into customer demand and pricing trends, track business performance and set accurate budgets.
