When estimating the monthly cost of a per hour service, over the course of a year, you need to know how many hours in a month. For some reason a simple “average hours in a month” Google Search yields unhelpful results.
730.5 AVERAGE HOURS IN A MONTH
There are 365.25 Julian calendar days per year (366 days in a leap year), 24 hours in a day and 12 months.
365.25 days X 24 hours / 12 months = 730.5 hours
So now you can estimate monthly cost for hourly services, such as Cloud Services.
example: $.10/hr * 730.5 = $73.05 average cost per month over a year
