Uptime Calculator

🕒 Uptime Calculator

Enter a system uptime percentage to calculate the equivalent downtime over different periods. This is essential for evaluating hosting SLAs (Service Level Agreements), server performance, or network reliability.

📘 Usage:

  • Enter the expected system uptime percentage (e.g. 99.9)
  • Click "Calculate"
  • See expected downtime per day, month, and year

📌 Why This Tool is Critical:

Small differences in uptime % mean major differences in reliability. For example:

  • 99% = 87.6 hours of downtime/year
  • 99.9% = 8.76 hours/year
  • 99.999% (Five Nines) = just 5.26 minutes/year!
Hosting providers often charge based on these guarantees.
