A clearer plan for your callback queue
Can your team clear the backlog by Friday?
Turn open cases, new arrivals, and real working time into a capacity plan. See what your team can finish before you commit to overtime.

128 daily capacity − 80 new cases = 48 fewer open cases/day
Four people · eight-hour days · 25% unavailable time · 80% planned utilization · nine minutes per completed case.
01 / TRY YOUR NUMBERS
A useful answer in a minute.
Start with the sample, then enter your team’s aggregate numbers. This demo uses the same staffing and arrivals each working day.
Estimated daily capacity
Capacity exceeds arrivals by 48 cases per day. With the same inputs each working day, the starting backlog clears in 5 working days.
See the calculation and its limits
Productive minutes = people × hours × 60 × (1 − unavailable time) × planned utilization. Minutes per completed case = minutes per attempt × average attempts per completion. Daily capacity is productive minutes ÷ minutes per completed case, rounded down to whole cases. End-of-day backlog = max(0, starting cases + new cases − capacity). Clearance days = starting backlog ÷ (capacity − daily arrivals), rounded up, when capacity exceeds arrivals. Unused fractional case capacity does not carry to the next day.
This is an aggregate workload estimate, not a live inbound queue or service-level forecast. It assumes work can be attempted when needed, effort is reasonably stable, and your completion assumptions reflect real outcomes. Retry delays, unreachable customers, deadlines, and changing demand can change the result. Zero starting backlog means no existing backlog; new work may still accumulate if capacity is too low.
02 / PLAN THE ACTUAL WEEK
Monday’s team isn’t
always Friday’s team.
The full Callback Capacity Kit gives you a reusable, five-day planner with different staffing and arrivals for each day. Compare a uniform staffing alternative, save scenarios, and take a clear report into your team meeting.
Downloadable offline HTML planner with an optional .xlsx spreadsheet companion included. Open the HTML tool in a current desktop browser, or use the companion in a compatible spreadsheet app. One organization license. No subscription.

The kit is a planning tool. It does not connect to your phone system, assign work, contact customers, or guarantee completed callbacks.
03 / A PRACTICAL MANAGER WORKFLOW
From a number to a decision.
Use a normal week.
Start with typical handling time and attempts per completed case. Include the admin time that disappears from optimistic plans.
Find the capacity gap.
Separate the starting backlog from new arrivals. A busy team can finish plenty of work while the queue still grows.
Choose one action.
Change staffing, protect productive time, or revise the target. Save the plan, then compare your assumptions with actual results.
A FEW USEFUL DETAILS
Simple tool.
Visible assumptions.
Who is this designed for?
Managers of small callback, follow-up, and service teams with a countable backlog of similar cases. It is most useful when you can estimate average total effort per completed case. It does not model a live inbound queue or forecast service levels.
Does my data leave my browser?
The free calculator runs in this page without sending your input numbers to a server. The paid planner works offline and lets you explicitly save data to your own files. This demo has no analytics or advertising trackers. Visiting the site still involves ordinary hosting requests.
Is this an Excel spreadsheet?
The kit includes a self-contained HTML planner plus an optional .xlsx spreadsheet companion. Open the HTML tool in a current desktop browser, or open the companion in a compatible spreadsheet app. The HTML planner also includes CSV export. No macros, account, API key, or subscription is required to use either downloaded planner.
What if we have different kinds of work?
Use a separate plan for each work type, or use a carefully weighted average effort. Do not count the same person’s available time in multiple plans. Retry windows, skill restrictions, dependencies, and uneven case complexity require manager judgment.
Can I buy the kit right now?
