Support Tickets per Customer Calculator

The Support Tickets per Customer Calculator measures how often your customers contact support, a metric often called the contact rate. You enter the total number of support tickets raised in a period and the number of customers over that same period, and the tool divides one by the other to give the average tickets per customer. Support leaders, product managers and customer success teams use this to gauge how much help the product needs, plan staffing, and catch problems before they grow. A rising figure usually points to confusing features, broken onboarding or a recent change that is generating extra contacts, so it works as an early warning system as much as a workload measure. It pairs naturally with support cost per customer, because more tickets per customer tends to drive the cost to serve up, and tracking both lets you tell a product problem apart from a staffing one. For a reliable reading, match the ticket period to the customer period, decide whether you are counting unique customers or all accounts, and keep that definition steady from month to month so the trend stays comparable. It also helps to segment the result by plan or customer type, since a small number of complex accounts can dominate the average and mask what most customers experience. Watch the number after you ship documentation, self-service or product fixes, because those investments should push it down. Use this calculator to set a baseline, size your support team against real demand, and prioritise the fixes that will quietly remove the most tickets and free your team to handle the conversations that matter.

Tickets per customer = total tickets / customers.
