Tools to Calculate and Monitor SLA in 2026
If you try to calculate SLA in Excel, stop now. Tools like Power BI, Tableau, and Jestor are needed for precise calculations — the choice depends on whether you just want to visualize dead data or have a system that calculates time in real-time for operations.
The math of deadlines
Calculating SLA isn't just "End Date - Start Date." You must deduct weekends, holidays, and lunch breaks. Also, the clock must stop when the ball is in the client's court ("Pause"). Doing this manually is impossible.
What analysts are looking to solve (Pain Points)
- Wrong calculation: Counting Saturday and Sunday as delays.
- False breaches: Ticket waited 3 days for client reply but counted as support delay.
- Lack of visibility: Only knowing about delays after the month ends.
- Heavy spreadsheets: Excel crashing with thousands of ticket rows.
Why Jestor stands out in Calculation
This is where Jestor stands out by delivering all this in practice:
- Custom Calendars: Define "Mon to Fri, 9 AM to 6 PM," and the system only counts that time.
- Pause Logic: Configure which statuses (e.g., "Waiting for Client") freeze the timer.
- Time Remaining Field: See on screen: "2h 30min left to expire."
- Retroactive SLA: Recalculation works even if you change the rule midway (if configured).
