Forecasting. Capacity. Scheduling. Cost.

What Turnella is for
Built for any team that has to plan a workforce
If your workload rises and falls, your staff time is limited, and labour is one of your biggest costs, you have a workforce planning problem. Turnella turns demand into a plan — whatever kind of work your team does.
Free staffing calculators
No sign-up required. Each calculator uses the right model for the type of work and tells you which model it is using and why.
Combine different types of work in one planning view. Add each workstream, choose the right capacity model, and compare the total requirement against a blended planning estimate.
Open calculator →How many agents do you need to hit your service level target? Enter calls per interval, AHT, and your SL target.
Open calculator →Chat is not voice. Agents handle multiple sessions simultaneously. Get the right headcount using a concurrency model, not Erlang C.
Open calculator →How many agents do you need to keep up with incoming cases and clear your backlog before SLA deadlines? Different math from Erlang, and we do it right.
Open calculator →Add breaks, meetings, training, sick leave, and admin time. Convert your seated requirement into your scheduled headcount.
Open calculator →Why Turnella
Honest math, per channel
Erlang C for voice. Concurrency models for chat. Backlog and flow models for email and tickets. We use the right formula for each type of work, and we tell you which one and why.
Cost per contact, not just headcount
Enter your hourly rates and see exactly what this staffing plan costs: weekly, monthly, and per unit served. The number every operations manager needs but Excel buries.
What-if scenarios
What if AHT drops by 30 seconds? What if you hire 5 people? What if chat concurrency increases? See the staffing, cost, and SLA impact instantly.
Built for teams that plan in Excel
Upload a CSV from your phone system, ticketing tool, or scheduling sheet. No implementation project. No training. No consultant required.
Built to grow with your planning
Start with calculators and a simple workstream. Add forecasts, requirements, schedules, cost assumptions and scenarios as your planning process becomes more structured. The tool grows with you, not ahead of you.
No per-seat pricing wall
Traditional WFM tools bill for every login, which quietly discourages the people who should see the plan from ever opening it. Turnella carries no per-user licence — the cost never scales with how many people need to look at the numbers.
How it works
Import your data once. Turnella connects every step from raw history to a costed, schedulable plan.
Import data
›Upload a CSV or JSON from your ACD, CRM, or ticketing tool. Turnella auto-detects date, volume, and AHT columns.
Forecast demand
›Multiplicative decomposition from your history. Day-of-week patterns, trend, and intraday profile computed automatically.
Calculate requirements
›Erlang C for voice. Concurrency model for chat. Backlog flow for email. The right formula runs for your channel type.
Build and test a schedule
›Define shift templates. The coverage chart overlays scheduled headcount against the requirement, interval by interval, so you can see where the plan breaks before it does.
See the cost
Weekly labour cost, FTE equivalents, and cost per contact, computed from your actual schedule.
The free calculators cover step 3 for a single channel. The full app connects all five steps and lets you save, compare, and export.
