MTTD & MTTR Incident Response Calculator
Calculate mean time to detect, mean time to resolve, MTBF and resulting availability from incident data.
Your inputs
Change any value to update the result instantly.
Availability
99.7608%
MTBF
730 hrs
Mean time to detect
15 min
Mean time to resolve (incl. detect)
105 min
Incidents in period
12
Total time-to-restore combines detection (MTTD) and resolution (MTTR) time.
Formula and working
Availability = MTBF ÷ (MTBF + MTTR); MTBF = total uptime ÷ number of incidents
- 1
Collect the inputs
Total operating time (hours) = 8,760 hrs; Number of incidents in period = 12; Mean time to detect (minutes) = 15 min; Mean time to resolve (minutes, from detection) = 90 min
- 2
Apply the formula
Availability = MTBF ÷ (MTBF + MTTR); MTBF = total uptime ÷ number of incidents
- 3
Result
Availability = 99.7608
