These prices were updated 03-09-2013
The change this go around was a drop in the yearly contracts for some of the ec2 instance types. Anywhere from 13-23% savings.
Types
EC2 comes in several types.
They come in different sizes and in linux/windows flavors. Their CPU power is listed by EC2 Compute
Units, “One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2
GHz 2007 Opteron or 2007 Xeon processor.” [8]
Here are the current types and
cost per hour on the East Coast Facility (N. Virginia) 01/24/2012.

MONTHLY costs
I prefer to think of the monthly 24x7 costs of servers so I
calculated that with this chart
(price*24*31) 24 hours a day 31
days in a month.

Yearly Rates
You can also pay a one-time fee for a “Reserved”
instance. A reserved instance does two
things, it guarantees you a spot for
your server (should a zone get full… a rare thing) and it also lowers your
hourly charge for running the server.
There are a few different options for the upfront costs,
light medium and Heavy. One year or
three year contract. For these
calculations I assume a heavy usage (24x7) and only a 1 year contract.
I am also only going to go over the Linux prices here.
