The trade-in question most worth asking today is not whether waiting cost money already; it did, up to $120 on some models, the day iPhone 18 Pro was announced. The live question on pre-order day is whether waiting any further, past today, changes anything at all, and Apple has not published a reason to think it will.
Apple’s trade-in figures moved once, on September 9, without warning and without a published explanation. Nothing in what Apple has published says when, or whether, they will move again.
Key facts
| Item | What Apple has published |
|---|---|
| Last confirmed change to trade-in values | September 9, the day of Apple’s event |
| Direction of that change | Down for iPhone, in some cases by as much as $120, based on values recorded per model |
| Apple’s published US trade-in range today | $175 to $885 in credit for an iPhone 13 or later |
| Apple’s published UK trade-in figure today | Up to £455 for an iPhone 16 Pro or later |
| Published schedule for the next change | None. Apple has not stated when trade-in values are revisited |
The drop already happened, before pre-orders even opened
The value already fell three days before today’s pre-order window opened at 12:00 UTC. Anyone who held onto an old iPhone through the announcement, hoping a launch-week bump would arrive the way it sometimes has in other years, traded against a lower number than the one that applied on September 8. That part of the story is settled and cannot be undone by waiting further. The reduction applied broadly, with values recorded for several generations of iPhone all moving down on the same day, not a single model singled out.

What waiting now would actually be betting on
Choosing to wait past today, rather than trading in now, is a bet that Apple’s range moves up again before the trade is completed, since Apple locks in whatever figure is published at the moment the trade-in is actually processed, not the moment someone first considers it. Apple has never published a pattern for how often it revisits these figures, so there is nothing in Apple’s own record to say that bet pays off. The only confirmed fact is the direction of the last move, which was down. A reader weighing this decision is not choosing between a known higher number later and a known lower number now; both later figures are unknown, and only today’s is published.
| Choice | What is known | What is not known |
|---|---|---|
| Trade in now, alongside the pre-order | Today’s $175 to $885 US range applies | Whether a future change would have been higher or lower |
| Wait and trade in later | The value used will be whatever Apple publishes at that later date | When, or whether, Apple changes the figures again |
Why instant credit removes some of the guesswork
Apple’s own trade-in credit is applied instantly against a purchase, which means choosing to trade in alongside today’s pre-order locks in today’s published range rather than leaving it exposed to whatever comes next. A carrier route, paid out over 24 to 36 months, carries a different kind of uncertainty, since the tiers behind its own headline number sit only in Apple’s footnotes and are not something either carrier has confirmed on its own site as of this writing.
What has not been confirmed
Apple has not published a reason for the September 9 change, a schedule for future changes, or any statement that values will rise again before or after iPhone 18 Pro ships on September 18. It has not said whether the range is reviewed on a fixed calendar or adjusted whenever Apple chooses, and no source checked for this article supports a claim that trade-in values reliably rise or fall around a launch.
Pre-orders remain open now, September 12, ahead of iPhone 18 Pro reaching stores on September 18. Whatever a trade-in is worth today is a fact Apple has actually published; whatever it might be worth at some later date, closer to that delivery or well beyond it, is not.
