SLA Attainment Calculator
This SLA attainment calculator shows how close you are to target, and how many breaches the target actually permits before anyone should worry.
SLA attainment calculator
Duplicates inflate the denominator and hide breaches: two tickets for one problem means one of them ages quietly in the queue while the other gets answered.

Attickets a month, that is 3 working days spent answering something the team already answered, usually because the customer chased on another channel.
What the SLA attainment calculator is really counting
Attainment = (tickets in period minus breaches) divided by tickets in period.
The trap is the denominator. Duplicates inflate it, which inflates your attainment percentage, because a duplicate that was merged or quickly closed counts as a compliant ticket.
So a queue with 15% duplicates reports better SLA performance than it delivers, and the customers who noticed aren't in the number.
The duplicate that breaches quietly
When one problem produces two tickets, one usually gets picked up quickly and the other sits. The customer is happy because they got an answer, so nobody escalates, and the second ticket ages until it breaches.
Your report then shows a breach that no customer complained about, which teaches everyone to distrust the SLA report. Merging the pair on arrival removes both the phantom breach and the distrust.
Frequently asked questions
How do you calculate SLA attainment manually?
Tickets that met the target divided by tickets in scope. Use this as an SLA calculator support teams can check their reporting against, because how to calculate SLA attainment gets contested the moment a target is missed.
How does this SLA attainment calculator work?
Tickets that met the target divided by tickets in scope, as a percentage. The SLA attainment calculator also shows how many breaches your target allows at your volume, which is the number people forget.
Should merged tickets count in SLA reporting?
Exclude tickets closed by merge from the denominator. Counting them flatters your attainment for work you never really did.
What SLA target is realistic?
Whatever you can hit 95% of the time on your worst week, not your average one. Targets set on averages break every time volume spikes.
Stop reporting phantom breaches
Merge duplicates on arrival and your SLA numbers start describing what customers actually experienced.
