Which phone it is doesn’t really matter to me. I’m concerned about low payments. I don’t mind owning the previous gen if it get me a $13 monthly payment over a $28 monthly payment for the current gen
My understanding is, if you're just going carrier, your repayments will likely be the same now or later, they may be higher later and your trade in will almost certainly be lower later, so on that basis go now.
If somehow, your carrier is offering a 15PM after the 16PM, then it's a calculation, which unfortunately you can only really do, after the 16PM releases to know if you made the right call to wait or not, it's something like.
If yz - yx > v - w, then you should've traded in your 12PM before the 16PM, else you're safe to wait.
v = 12PM 2024 trade in
w= 12PM 2025 trade in (realising it will still be 2024, but after 16PM gets released)
years = y
repayments 15PM = x
repayments 16PM = z
You can run the calculation now, then speculate the calculation in the future using the 11PM trade-in value, but it won't be accurate.
Again, I'm more surprised if your carrier currently offers a 14PM on repayments? This isn't available in my region, if this is available, then this is worth entertaining, see what the 14PM repayments are now and substitute the 11PM trade in. If it doesn't, well, you should probably organise for the 15PM now to have the most for your trade in, or, sell your 12PM private now or later to maximize value.
