THE NUMBERS, EXPLAINED
How to use this calculator.
Constant arrivals and processing capacity during the coverage period. Fluid workload approximation; it does not model bursts or priority queues.
Start with your inputs
Enter incoming alerts (alerts/hour), mean triage time (minutes/alert), concurrent analysts (count), coverage period (hours), starting backlog (alerts). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Incoming alerts (alerts/hour) | 30 |
| Mean triage time (minutes/alert) | 4 |
| Concurrent analysts (count) | 1 |
| Coverage period (hours) | 8 |
| Starting backlog (alerts) | 20 |
A worked example
With the example inputs above, triage capacity (alerts/hour) is 15. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Triage capacity (alerts/hour) | 15 |
| End backlog (alerts) | 140 |
| Analysts to match arrivals (count) | 2 |
How this is calculated
Triage capacity (alerts/hour)
Divide analyst minutes per hour by minutes per alert.
End backlog (alerts)
Add arrivals and subtract available processing from starting backlog, floored at zero.
Analysts to match arrivals (count)
Round the concurrent analyst workload upward.
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Constant arrivals and processing capacity during the coverage period. Fluid workload approximation; it does not model bursts or priority queues.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Triage capacity (alerts/hour); End backlog (alerts); Analysts to match arrivals (count). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Constant arrivals and processing capacity during the coverage period. Fluid workload approximation; it does not model bursts or priority queues.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
