Why this page exists

Service reporting gets easier when opened or assigned cases and closed cases turn into one closure-rate percentage instead of being reviewed only as raw counts. This calculator helps visitors estimate case closure rate, remaining open cases, and a simple period summary from the counts entered.

Calculator

Case closure rate calculator

Estimate case or ticket closure rate from total opened or assigned cases and total closed cases.

Result

90.00%

Estimated case-closure rate based on total closed cases divided by the total cases opened or assigned in the comparison period.

Summary68 cases remain open in this period view

612 closed cases against 680 opened or assigned cases gives a closure rate near 90.00%.
68 cases remain open in this simple period comparison.
Use the result as a practical support or operations snapshot only, because reopened cases, backlog work, and period timing can all affect the interpretation.

This is a simple period-based rate. The result is easiest to interpret when the opened or assigned count and the closed count are measured on the same period basis.

How it works

What the calculator is doing

Enter total cases opened or assigned and total cases closed over the comparison period.

The calculator divides closed cases by the opened or assigned count.

It shows the closure-rate percentage and how many cases remain open in the same simple period view.

Understanding your result

This is a period-based rate rather than a full queue model. Reopened cases, backlog work, and timing differences can affect how the result should be interpreted.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Track case closure for a team or queue

A closure-rate percentage can make support performance easier to compare across periods than raw open and closed totals alone.

Compare two service periods on the same basis

Using the same opened-or-assigned basis each time can make it easier to see whether case closure is improving or slipping.

Use it with support metrics

Case closure often fits naturally beside first-response, task-completion, and SLA-compliance tools.

FAQ

Common questions

How is case closure rate calculated here?

The calculator divides total closed cases by the total opened or assigned case count entered for the comparison period.

Why might the closed count be above the opened count?

That can happen when older backlog cases are closed during the same period, which is why it helps to stay clear about the comparison basis being used.

Does this show the whole support picture?

No. It is only one period-based service metric, so backlog age, reopen rate, quality, and SLA performance can still matter separately.
