Trade-In Discount Calculator
A trade-in looks like a discount, but the thing paying for it is the device you hand over. The list price minus the credit is what you actually pay, and the credit over the list price is the real discount rate.

What it means
Selling it separately fetches that much more — weigh the gap against the hassle of doing it yourself.
Formula
Final price = List price − Amount
If the credit falls short of the resale price, that gap is your cost — though the time and risk of selling privately belong in the comparison too.
