- 82 /3 / 12 = 2.27 (fixed monthly cost for a reserved instance)
- .007 * 24 * 30 = 5.04 (variable monthly cost)
for a total of $7.31, assuming it's running all the time. If it's running only during business hours, the variable monthly cost becomes:
- .007 * 8 * 20 = 1.12
But the thing is, even the micro instance does almost NOTHING when used as a VPN endpoint (CPU and memory are flat) so you can use the machine for anything else (hosting, dealing with other VPN clients, etc.)
The same thing - doing almost nothing when a VPN endpoint - applies to other VPSes at half or less the cost, e.g. http://www.lowendbox.com/blog/forever-hosting-19-95year-256m... - 20 USD/year. Now these are smaller instances, likely more contended, but that's precisely the point - when you don't need much, there's not much value in over-provisioning.
Anyhow, I've said my piece; I think EC2 is over-priced for this specific task; there are other options; and (at least in my case) they aren't blocked by SO, owing to not being as mainstream.
