Looking at the price of current year refurbs, I'd say your math leaves much to be desired. Also I've stated this before, but imac used value hinges on the condition of the display. If it looks old and ugly, that kills the resale value.If you can sell your iMac on Craigslist for about 80-90% of retail for a new one. Then upgrade whenever you feel like it and can afford it.
There are several in my area being sold for $1400-1800 depending on 2009 i5 or i7.
You'd be paying approx. $300-$400 for an '09 i5 27" -> '11 i5 27" upgrade.

For the OP, it's time to update when the computer ceases to do what you need in a timely manner. 2013 should be the next really major upgrade from intel. I can't personally wait that long, but my requirements jumped significantly in the past year (or I probably would). We're really past the days where you need to update frequently for most things.
I have an iMac from 2009 and it's still running great. I expect to get many more years of quality use out of it. It is my secondary iMac as I have a 2010 iMac as my primary one now. but still, the 2009 is just fine.I have a iMac from late 2009 and I was just wondering should I update, or is it fine to keep and upgrade, when would this model be considered old?
Yeah.... $1400 for a 2009 sounds way too high. You can get a current year 27" refurb for $1419 (i5 just checked). A 2009 model should be way less especially considering the lack of warranty, and if the display is starting to show the typical imac display aging signs (purple edges, image persistence, loss of contrast/uniformity) that brings it down further. It's possible that many people pay too much for used Macs, but it's totally illogical to spend almost as much on one that's a couple years old. They do not run forever, and they're expensive to repair.If I sell an '09 iMac for $1400.00
A brand new one costs $1699.00
Tax here is 8% which on $1699 is $135.92. $1699 + 135.92 = $1834.92
$1834.92 - $1400 =$434.92
I did mention approx. $400. Which is close to $434.92
For me I never look at refurb prices because I don't want to wait for them to ship one to me.
Check Apple online and OTD price is $1,839.17 w/ estimated price.
