Again this makes no sense:
1. Why would you want to trade in the phone only to re-up IUP after just one year???
2. You cant trade in a phone to enter the IUP. Unless you use the regular Apple financing
Re-doing the math again for you in case you dont get it:
Based on your choice above, If you are currently on IUP and chose to pay off the remaining balance at the time of preorder, your out of pocket cost is $1320 (720 + 600).
Then you take the phone trade it in and pay an additional 520 out of pocket for the new iPhone (Apple credits you 800 for the old phone) bringing your total out of pocket costs (in one year) to 1840. Assuming you are not paying for AppleCare+.
Meanwhile your fellow Apple fan pays 1440 over 2 years! And has AppleCare+ to boot.
At the end of 2 years you both have an iPhone 13 that has been used for 1 year, you have paid $1840 out of pocket (720 for year 1 of IUP + 600 to buy out the IUP contract + 520 out of pocket to get the new iPhone which you own outright) while the other fellow paid $1440 (720 for year 1 of IUP + 720 for year 2 of IUP)
But choices am i right?
Your math is off. You forgot that you still owe IUP $600 in year 3...
Let me break it down for you, again. Both examples include AppleCare+ and let's only run for 3 years.
Assuming you are doing IUP for 2 years, starting 2020 with iPhone 12 Pro, and this year you want to get iPhone 13 Pro and "re-up" IUP
2020 - $720
2021 - $720
2022 - $600
-----------------
$2040
Assuming you are doing IUP in 2020 for iPhone 12 Pro, and this year you pay off $600 and trade-in to get $800. Then you pay $1320 up front out of pocket (or re-up IUP again, doesn't matter)
2020 - $720
2021 - $600 + $1320 - $800 (trade-in)
2022 - $0
-----------------
$1840
Clear enough? Once you add back the $600 you still owe in year 3 that $200 difference suddenly shows up again. You can keep doing IUP every year and losing more and more money, or pay if off and trade-in every year.

You know every year you return phone in IUP and get a new one you are starting a new IUP right? You don't trade-in phone to enter IUP. Again, these are 2 separate events. Not sure why people think IUP Is some special program that Apple creates for the benefits of consumer. It's just a 24-month 0% interest loan WITH Apple guaranteeing floor of depreciation value of the phone after 1 year. This is GREAT if we are talking about android phone that depreciates 50-70% after 1 year, but iPhone does not. Think of this way, Apple creates 2 paths for you on IUP. One where Apples pays you 50% after 1 year and gladly takes it back when you return, and the other one Apple pays you 640 (+100 refund from AppleCare+) if you pay off the $600 left owe on the phone. You are literally choosing the one that Apple pays you the lowest, and leaving money on the table.
Hope this is clear enough.
