Calculator Inputs
The page stays in a single central content flow, while the input fields switch to 3 columns on large screens, 2 on medium screens, and 1 on mobile.
Example Data Table
| Period | Opening Backlog | New Tickets | Resolved | Reopened | Canceled | Ending Open | Closure Rate |
|---|---|---|---|---|---|---|---|
| 30 Days | 120 | 340 | 360 | 25 | 20 | 105 | 98.63% |
| 14 Days | 78 | 140 | 132 | 10 | 8 | 88 | 88.00% |
| 7 Days | 42 | 66 | 72 | 4 | 3 | 37 | 102.86% |
Example formula check for row one: 120 + 340 + 25 - 360 - 20 = 105 ending open tickets.
Formula Used
Ending Open = Opening Backlog + New Tickets + Reopened Tickets - Resolved Tickets - Canceled Tickets
Closure Rate (%) = Resolved Tickets / (New Tickets + Reopened Tickets) × 100
Reopen Rate (%) = Reopened Tickets / Resolved Tickets × 100
Overdue Share (%) = Overdue Open Tickets / Ending Open Tickets × 100
Days to Clear = Ending Open Tickets / (Average Daily Resolved - Average Daily New)
This only works when daily resolved tickets are greater than daily new tickets.
Pressure Score = (Ending Open + 1.5 × Overdue Open + 2 × Escalated Open) / Period Days
This is a practical management index, not a formal industry standard.

FAQs
1) What does open ticket count mean?
It is the number of unresolved support cases remaining after you add incoming work and subtract completed or canceled work for the same reporting period.
2) Why are reopened tickets added back into the backlog?
A reopened case becomes active work again. It should return to the queue because agents still need time to investigate, respond, or complete a corrected resolution.
3) Should canceled tickets reduce open count?
Yes. If a ticket is closed as duplicate, spam, invalid, or customer-abandoned, it leaves the active queue and reduces ending open volume.
4) What is a good closure rate?
A healthy rate usually stays near or above 100% when measured against new plus reopened tickets. That means the team is keeping up with intake or shrinking backlog.
5) Why can days to clear show “Not Clearing”?
That appears when daily intake equals or exceeds daily resolution. In that situation, backlog will stay flat or grow unless staffing, workflow, or automation changes.
6) How should ecommerce teams use overdue share?
Use it to track service risk. A rising overdue share often signals slow responses, fulfillment complexity, policy confusion, or seasonal spikes needing immediate action.
7) What does the support pressure score help with?
It highlights queue intensity by weighting overdue and escalated work more heavily than ordinary tickets. Teams can use it for staffing, prioritization, and escalation monitoring.
8) Can I use this for weekly and monthly reporting?
Yes. Enter values for any consistent period. Weekly, biweekly, and monthly reviews all work as long as the inflow, outflow, and average daily figures match the same window.
Notes for Ecommerce Operations
Open ticket counts matter most when tied to order delays, returns, damaged items, payment issues, refund requests, and delivery exceptions. For ecommerce support, queue quality is often more important than raw volume alone. That is why this page also tracks overdue workload, escalations, reopen behavior, and expected backlog direction.
