Anyone here good with numbers?

I'm currently looking at the difference in price between going to a Samsung Galaxy Nexus by getting a contract (£35-ish/month) or by buying up front (£480+10/month). This works out to about £120-£140 cheaper by buying the phone myself, depending on exactly how I do it.

My question, then, is about discounting future costs. If I spend £480 now rather than in chunks then I lose the utility of that money over the next two years. How does one account for that?

I assume there's a simple equation I could plug in that would tell me to stop being so stupid and just buy the fucking phone, but I'd like to be sure...
