Service Level Calculator
Enter offered contacts and contacts answered within your target for each period. The result uses the same short-abandon policy as your source data.
A QUICK WALKTHROUGH
How to use this tool
- Enter the offered and within-target contact counts for each period.
- Add or remove periods as needed, up to 24.
- Enter your target percentage and calculate the weighted service level and gap.
Weighted across periods
The calculator sums all offered contacts and all contacts answered within target before calculating one overall percentage. It does not average each period percentage.
Use your source policy
Include short abandons consistently with the source report or policy you are evaluating. The calculator does not assume that 80/20 is a universal standard.
