New iphone costs $27.94 more than the old iphone

11 pointsby jarnoldalmost 17 years ago
Okay, we all know that the new iphone price is just a marketing ploy to get people in more expensive contracts. But how much more will it cost you. Assuming a 5% opportunity cost for your cash.<p>New iphone w/ $69.99 plan: ($1,794.34) =PV(5%/12, 24, 69.99) - 199<p>Old iphone w/ 59.99 plan: ($1,766.41) =PV(5%/12, 24, 59.99) - 399<p>The new, $199 iphone costs $27.94 more than the $399 old iphone when you consider the monthly plan and time value of money.

"The 8GB 3G iPhone will cost just £99 on a new £30 per month tariff and the existing £35 per month tariff. Consumers choosing either the £45 or £75 per month tariffs will get the 8GB 3G iPhone for free."<p>That's much better than the previous offering. I was looking at the £35 per month tariff with iPhone v1, but the ~£300 price tag put me off. So now I can get the same tariff and a reduced up-front cost -- what's not to like?<p><a href="http://www.telegraph.co.uk/money/main.jhtml?xml=/money/2008/06/10/bcnapple210.xml" rel="nofollow">http://www.telegraph.co.uk/money/main.jhtml?xml=/money/2008/...</a>

What is the 5%? Why do you not just do $10 * 12 months?
