🔍 What This Tool Does

It predicts your end-of-day Service Level (SLA) using a simple weighted SLA method. Enter a few values and the calculator estimates your final SLA instantly.

📥 Input Details

• Total Forecast Calls: Calls expected for the whole day.
• Actual Calls So Far: Calls handled up to now.
• SLA So Far (%): Current SLA achieved on those completed calls.
• Expected SLA for Remaining: Your forecast SLA for the rest of the day.

🧮 Calculation Logic

The formula used is:

Final SLA =
  ( (Actual Calls × SLA Now)
  + (Remaining Calls × Forecast SLA) )
  ÷ Total Forecast Calls × 100

Because SLA is volume-weighted, intervals with more calls influence the final SLA more than low-volume intervals.

🎯 Why This Helps WFM Teams

• Quick end-of-day SLA forecasting
• Supports intraday staffing decisions
• Early warning of SLA dips
• Useful when interval-level data is incomplete
