How to Calculate Uptime?

Uptime is typically calculated using the following formula:

Uptime (Uptime (%) = \frac {Total Time – Downtime} {Total Time} \right) \times 100

Uptime is a metric calculated as the percentage of time that a system is available and operational. There is an uptime of 100% if there is no failure in a given timeframe.

Where:

  • Total Time is the entire duration being measured (e.g., a month, a year).
  • Downtime is the total time the website was unavailable during that period.

For example:

  • If a website is operational for 30 days (43,200 minutes) and experiences 60 minutes of downtime, the uptime percentage would be: 43,200-60=43,200 x 100=99.86%
