Average deal size, also known as average contract value or ACV, is a metric used by SaaS companies that represents the average amount of money that customers spend on a solution. Another way to explain it is the average amount of money a business makes per deal they close.

Average deal size can be calculated by taking the total revenue earned in a given period and dividing it by the number of closed-won opportunities during that timeframe. ACV is often calculated on a monthly or quarterly basis and used as a key performance indicator (KPI) for the business. Average deal size can be a helpful metric to use when evaluating the performance of sales teams, and it can also be used to determine the price points that are most likely to see leads convert.
