What is the formula for calculating sales per day?

Average daily sales are calculated by dividing the annual sales by the number of days in the sales period. This formula allows a business to calculate its sales per day using information from annual, quarterly or semi-annual sales.

According to the Houston Chronicle, sales revenue is the profit a company makes after it pays its creditors. Calculating daily sales helps a business position itself during the lean times of the year. Additionally, this information assists a business owner by identifying areas for improvement, such as limiting spending in certain quarters. Calculations of sales data are used for different divisions in a company to identify its weaknesses and strengths.
