The Average Order Value (AOV) Calculator helps businesses determine the average amount customers spend per order. It works by taking two user inputs: Total Revenue and Number of Orders. When the “Calculate AOV” button is clicked, the calculator checks that both values are valid (total revenue must be zero or more, and orders must be above zero). If validated, it divides total revenue by the total number of orders, then displays the result as the AOV, rounded to two decimal places for clarity.
