I'm sure there are some out there. Here is how I calculate availability.

Availability = ((Time - Outage) / Time) * 100

Here are the important times. Everything else doesn't matter.

99.9% One Year 8 hours, 45 minutes, 35 seconds
99.8% One Year 17 hours, 31 minutes, 12 seconds
99.7% One Year 1 day, 2 hours, 16 minutes, 48 seconds
99.6% One Year 1 day, 11 hours, 2 minutes, 24 seconds
99.5% One Year 1 day, 19 hours, 48 minutes, 0 seconds
99.4% One Year 2 days, 4 hours, 33 minutes, 35 seconds
99.3% One Year 2 days, 13 hours, 19 minutes, 12 seconds
99.2% One Year 2 days, 22 hours, 4 minutes, 47 seconds
99.1% One Year 3 days, 6 hours, 50 minutes, 24 seconds
99.0% One Year 3 days, 15 hours, 36 minutes, 0 seconds

I searched "uptime calculator" and the first result was this:

http://easyuptimecalc.com/

Lets you calculate automatically what % uptime your site has - or you can give it a # of minutes of downtime and it will calculate that as a % uptime. I thought it was useful.

Hope this helps!

imaginemn is essentially correct. But I think there's an easier way. You don't need a 3rd party site. It's a simple formula:

Total time = 30 days per month * 24 hours per day * 60 minutes per hour = 43,200 minutes per month.

Take your uptime guarantee. In this example I'll use 99.99%:

(1 - .9999) * 43,200 = allowable minutes down per month.

So,

(.0001) * 43200 = 4.32 minutes.

I just finished this EzUTC.com (Ez UpTime Calculator) project. You simply enter either uptime percentage and timeframe or downtime and timeframe — then click "Calculate." Regardless, uptime and downtime are both instantly presented in percentage and days, hours, minutes and seconds format. The results also include bar, column and pie chart output.
