A basic workload estimate is agents × scheduled hours × 60 × share of time available for call work, divided by average talk and after-call minutes. It estimates total workload for a period. It does not predict when callers will arrive or how quickly someone can answer.
Estimate your staffed call workload
Illustrative inputs. Replace them with your own figures. Calculations stay in this browser; no account is needed.
Across 3 agents in this 6-hour window, rounded down. This is an average workload estimate, not a recommended buying cap.
- Minutes allocated to call work
- 756
- Talk + after-call work per call
- 15 min
- Average calls per agent in this window
- 16.8
3 × 6 hours × 60 × 70% ÷ (12 + 3 minutes). Arrivals can cluster; this average does not predict waiting time, answer rate, available supply or the number of simultaneous calls you can accept.
What belongs in each input
- Scheduled hours
- Use the same time window for each agent. If shifts differ, calculate each shift separately and add the resulting workloads.
- Time allocated to call work
- Leave time for breaks, coaching, meetings and other duties. This percentage covers both talking and after-call work; do not subtract after-call work twice.
- Average talk time
- Use measured handling data for the campaign and team you are planning. Include short and unbilled conversations that consume staff time.
- After-call work
- Include notes, disposition, follow-up setup and other work that keeps an agent from taking the next call. A disconnected phone does not always mean an available agent.
A worked example
Three agents scheduled for six hours create 1,080 scheduled minutes. Allocating 70% to talking and after-call work leaves 756 minutes. At 12 minutes of talk and 3 minutes of wrap-up, each handled call uses 15 minutes. That produces an average workload of 50.4 calls across the shift, shown as 50 whole calls. Every number is hypothetical.
Daily volume and concurrency are different
| Measure | Question it answers | What it does not establish |
|---|---|---|
| Workload capacity | How much work fits in these staffed minutes? | That calls will arrive evenly. |
| Daily call limit | How much volume is enabled under a campaign setting? | That every enabled call can be answered promptly. |
| Concurrency | How many calls can be handled at once? | How many calls the team handles across a day. |
| Answer rate | How many delivered calls were answered? | Whether those calls produced suitable customers. |
If three agents are each on a call, an additional arrival creates a capacity problem even when the team is far below its daily workload estimate. A daily cap cannot solve a short burst. Use measured arrival intervals and a queueing model when you need a service-level or waiting-time plan; this calculator does not provide one.
Match buying to real coverage
- Map actual shifts, lunch coverage and the time needed to finish calls after the buying window ends.
- Review enabled campaigns, destinations, receiving availability and configured limits before the shift.
- Pause or reduce receiving when agents leave or after-call work builds up.
- Review delivered, answered and billed calls together with talk and wrap time before increasing volume.
Unanswered calls do not meet Callmart's connected-time billing threshold. However, voicemail or an IVR can answer while no agent is available, and connected time after that answer can count. Check the destination behavior instead of assuming an empty desk prevents charges.
Revisit the estimate when the work changes
Recalculate when a new campaign changes average handling time, training creates additional after-call work or schedules change. Use your own observed call pattern rather than an industry average. The available publisher supply and your approved campaign terms determine whether the enabled volume can be delivered.
Common questions
01Should I set my daily cap to the calculator result?
Not automatically. It is an average workload estimate. Arrival peaks, concurrent calls, breaks and setup all affect a safe operating limit.
02Does it predict how many calls Callmart will send?
No. Delivery depends on eligible supply, approved campaigns, available capacity, funds and your settings. This tool only models the workload in your inputs.
