iPhone 18 Pro Trade-In Warning: Apple Could Offer You Up to $170 Less for Your Old iPhone — Other Buyers Up to $472 Less

SellCell compared iPhone trade-in prices from Apple, Verizon, AT&T, Gazelle and ecoATM — and beat the next-best quote on every one of the 15 iPhones analyzed.

Introduction

If you’re planning to buy an iPhone 18 Pro, trading in your current iPhone is one of the easiest ways to take some of the sting out of the upgrade price.

And if you’re buying directly from Apple, trading in your old phone at the same time is the obvious option. It’s quick and convenient — but it might not get you the best price.

SellCell compared trade-in prices for 15 iPhones on September 14, 2026, looking at the top prices available through SellCell alongside quotes from Apple, Verizon, AT&T, Gazelle and ecoATM.

To keep things like-for-like, we compared equivalent phones on every site: the highest storage capacity available for each model, unlocked and in good condition.

Apple’s quotes were below SellCell’s top prices on every comparable iPhone we checked, with the difference reaching $170. And across all five alternatives, SellCell beat the next-best quote on all 15 models — by as much as $168.

Against individual trade-in options, the difference was even bigger, reaching $472 on a single iPhone.

SellCell vs. Apple, Verizon, AT&T, Gazelle and ecoATM

For each iPhone, we also identified the highest quote from Apple, Verizon, AT&T, Gazelle or ecoATM. This gives us the “next-best” price and means we’re comparing SellCell with the strongest alternative quote for each phone.

SellCell came out on top across all 15 iPhones.

The biggest cash advantage over the next-best quote was on the iPhone 16 Pro Max. SellCell’s top price of $780 was $168 higher than the closest alternative at $612.

The iPhone 14 had the biggest percentage difference, with $286 available through SellCell compared with a next-best quote of $203 — $83, or 40.9%, more.

Even on the newest phones, the differences were significant. SellCell’s $999 top price for the iPhone 17 Pro Max was $114 above the next-best $885 offer, while the iPhone 17 Pro was $110 ahead.

Trading Your Old iPhone With Apple? Check the Price First

Apple Trade In is probably the easiest option if you’re already ordering an iPhone 18 Pro or Pro Max from Apple. That doesn’t necessarily make it the best-paying one.

SellCell vs. Apple Trade-In Prices

The biggest difference was on the iPhone 16 Pro Max. Apple offered $610 for the handset, while the top price through SellCell was $780.

That’s an extra $170 for exactly the same iPhone.

An iPhone 15 Pro was worth $370 through Apple compared with $490.99 through SellCell, a difference of $120.99.

For the iPhone 14, Apple offered $195 compared with $286 through SellCell. That’s another $91 — or 46.7% more.

The gap doesn’t disappear with newer handsets either. Apple’s $885 offer for the iPhone 17 Pro Max was $114 below SellCell’s $999, while the iPhone 17 Pro was $785 with Apple compared with $895 through SellCell.

If convenience is your priority, Apple’s trade-in service has an obvious appeal. But when the difference can run to $100 or more, it’s worth knowing what your iPhone is worth before accepting the offer.

How Does Verizon Compare?

Apple isn’t always the first stop when upgrading. Plenty of iPhone owners will be looking at carrier quotes, particularly if they’re also considering a new contract or plan.

So how does Verizon stack up?

SellCell vs. Verizon Trade-In Prices

Verizon offered $705 for the iPhone 17 Pro Max compared with $999 through SellCell. That’s $294 less.

For an iPhone 16 Pro, Verizon’s $440 was $211 below SellCell’s $651.

There were some big differences further down the range too. An iPhone 14 was worth $131 with Verizon compared with $286 through SellCell — a $155 gap.

For the iPhone 11, Verizon offered $57. SellCell’s top price was $122, more than twice as much.

What About AT&T?

The AT&T figures produced some of the largest gaps in the study.

SellCell vs. AT&T Trade-In Prices

The iPhone 17 Pro is a good example. AT&T offered $595 compared with a top SellCell price of $895, leaving $300 between the two.

The difference on the iPhone 16 Pro Max was $270 — $510 through AT&T versus $780 through SellCell.

One of the biggest percentage differences came from the iPhone 13 Pro Max. SellCell’s top price was $356, while AT&T offered $125, a difference of $231.

Carrier trade-in promotions can work differently from straightforward cash buyback quotes. Some involve bill credits, particular plans or other eligibility requirements, so it’s important to look at the full deal being offered.

But before committing to one, knowing the market value of the phone you’re handing over gives you a useful point of comparison.

SellCell vs. Gazelle

Gazelle came closer to SellCell on several models, particularly some of the newer iPhones, but there were still some sizeable gaps.

SellCell vs. Gazelle Trade-In Prices

Gazelle offered $825 for the iPhone 17 Pro Max compared with $999 through SellCell, leaving a $174 difference.

For the iPhone 16 Pro Max, it was $612 versus $780 — $168 more through SellCell.

The iPhone 15 Pro had a $108.99 difference, with Gazelle offering $382 compared with $490.99 through SellCell.

And on the iPhone 11, Gazelle’s $55 offer compared with $122 through SellCell, a difference of $67.

SellCell vs. ecoATM: Up to $472 More

This is where the biggest single cash difference in the study appears.

SellCell vs. ecoATM Trade-In Prices

ecoATM offered $423 for the iPhone 17 Pro. SellCell’s top price was $895.

That’s a $472 difference.

There was another $400 between the two prices for the iPhone 16 Pro Max: $380 from ecoATM compared with $780 through SellCell.

An iPhone 15 Pro was worth $222 through ecoATM versus $490.99 through SellCell, leaving a $268.99 gap.

And an iPhone 14 owner could be looking at $114 from ecoATM compared with $286 through SellCell — $172 more.

The differences aren’t small, particularly when that money is going toward the cost of a new iPhone.

Why Your Old iPhone’s Value Matters at iPhone 18 Pro Launch

When Apple launches a new iPhone, most of the attention naturally goes on the price of the new handset.

But if you’re upgrading, there are two numbers that matter: what the new iPhone costs and what you can get for the one you already own.

If two places will give you $610 and $780 respectively for the same iPhone, choosing the second doesn’t just mean getting a better trade-in price. It means you’ve got another $170 to put toward the upgrade.

And this is particularly worth thinking about around launch.

Our previous iPhone 18 trade-in research looked at how quickly older iPhones can lose value around Apple’s announcement and release. That makes both when you sell and where you sell worth considering.

The figures here also show why it’s worth looking beyond the first trade-in price you’re offered. Even when we ignored the lower offers and compared SellCell only with the next-best quote available for each handset, SellCell was still ahead on every model we checked.

Conclusion

Trading an old iPhone with Apple while buying an iPhone 18 Pro is easy. For some people, that convenience will be worth it.

But it’s worth checking the numbers first.

Apple offered $610 for the iPhone 16 Pro Max compared with a top SellCell price of $780 — $170 less. There was a $120.99 difference on the iPhone 15 Pro and a $114 difference on the iPhone 17 Pro Max.

The wider market makes comparing prices even more important.

SellCell beat the next-best quote from Apple, Verizon, AT&T, Gazelle or ecoATM on every one of the 15 iPhones we analyzed, with the difference reaching $168.

Against individual buyers, the gap reached as much as $472.

So if you’re planning to upgrade to an iPhone 18 Pro or Pro Max, don’t automatically hand over your old phone at checkout. Check what it’s worth first and then look at selling your iPhone.

It could leave a lot more money in your pocket for the upgrade.

Methodology

SellCell recorded iPhone trade-in prices on September 14, 2026, covering the 15 most traded-in iPhone models through SellCell, from the iPhone 17 Pro Max to the iPhone 11.

For each model, we compared the top trade-in price available through SellCell with the quoted trade-in price for the equivalent handset from Apple, Verizon, AT&T, Gazelle and ecoATM.

To keep the comparison like-for-like, every quote was based on the highest storage capacity available for that iPhone model, unlocked and in good condition.

The “next-best” price is the highest quote recorded from Apple, Verizon, AT&T, Gazelle or ecoATM for each handset. This was then compared with SellCell’s top price to show how much more was available through SellCell versus the strongest competing quote.

Prices were those quoted at the time of the research and can change. Final trade-in values may vary depending on device condition and the terms or eligibility requirements of individual trade-in services.
