Frequently Asked Questions
Common questions about the MTBF/MTTR Calculator
MTBF (Mean Time Between Failures) measures average time between system failures. Calculate it by dividing total operational time by number of failures: MTBF = Total Uptime / Number of Failures. For example, if a system runs for 8,760 hours (1 year) with 4 failures, MTBF = 2,190 hours. Higher MTBF indicates better reliability.
