How to use Percent Availability Calculator

Looking to determine the performance level of your system? Are you curious about your system’s availability but finding no way to calculate % Availability? We have created a % Availability Calculator to solve this problem. Enter the total uptime hours of your system and the downtime hours, then click the calculate button. The calculator will display the percentage availability of the system.

Formula to calculate % Availability

The formula to calculate % Availability (\(AV\)) is:

\[ AV = \left( \frac{\text{Total Uptime}}{\text{Total Uptime + Total Downtime}} \right) \times 100 \]


  • \(AV\): Percentage Availability
  • \(\text{Total Uptime}\): The total time the system is operational and available
  • \(\text{Total Downtime}\): The total time the system is not operational or experiences issues

Example: Suppose your system has 800 hours of total uptime and 200 hours of total downtime. Calculate the % Availability.


Using the % Availability formula:

\[ AV = \left( \frac{800}{800 + 200} \right) \times 100 = 80\% \]

Therefore, the % Availability of the system is 80%.
