Trade-In vs Selling Your Phone Yourself: How Much Money You Leave on the Table

Every buyback site says the same thing. Get a quote in 60 seconds, free shipping, paid in a few days. And all of that is true. What they don't put on the homepage is how much less you get compared to selling the phone yourself.

I wanted an actual number, so I pulled one.

What I compared

Andover collects offers every day from Gazelle, Rick's iStock and more than a dozen buyback companies that quote through Swappa's trade-in program. We also collect what the same phones are listed for on Swappa, Back Market, eBay and others.

For this I lined up 875 exact phone configurations (same model, storage, condition and carrier lock) where we had both a buyback offer and a Swappa price on the same day. Then I compared the single best buyback offer against what you'd actually keep on Swappa after their seller fee and PayPal.

The answer: about 69 cents on the dollar

Across all 875, the best buyback offer was about 69% of what the phone would net on Swappa. In dollars, the median gap was $89.

And that's the best offer. Plenty of buyback companies are lower than that.

The buyback offer beat Swappa about 6% of the time. So it happens, but if you just take a trade-in quote without checking, you're probably giving up real money.

One phone, sixteen offers

Here's what that looks like for one popular phone, an iPhone 15 Pro with 128GB in Good condition, unlocked, all on the same day.

Two things jump out.

First, the gap between Swappa and the best buyback offer is about $50 on this phone. That's the price of convenience.

Second, the gap between the best and worst buyback offer is $134. If you're going to trade it in, which company you pick matters more than almost anything else. Grabbing the first quote that comes up on Google can easily cost you $40 to $50 on a phone like this.

Where buybacks fall apart: Fair condition and carrier locks

The gap isn't the same for every phone. Two things make it a lot worse.

Fair condition. On Swappa, a phone listed as Fair sells for about 1% less than the same phone in Good condition. Buyers there are pretty forgiving about scratches. Buyback companies are not. Several of them offer 40% less for Fair than for Good. If your phone has visible wear, selling it yourself is almost always the better move. I went deeper on this in Mint vs Good vs Fair.

Carrier locks. Marketplaces barely discount a locked phone. Buyback companies do, and sometimes by a lot. Gazelle was offering about half as much for T-Mobile locked phones as for unlocked ones. More on that in Is a carrier-locked phone worth less?

When a trade-in actually makes sense

I'm not anti buyback. I use them. They make sense when:

• You need the money now. A buyback pays in days. A Swappa listing might take a week or two to sell, plus shipping time.
• Your time is worth more than the gap. Taking photos, answering questions and shipping a phone is maybe an hour of work. If the difference is $30, that's a fair trade for a lot of people.
• The phone is newer and in great shape. Buyback offers jump a lot for Mint condition, often 15% to 30% over Good, so the gap to selling yourself gets smaller.
• The buyback offer is actually higher. It happens about 6% of the time. You won't know unless you check both.

And they make less sense when the phone is in Fair condition, carrier locked, or older and cheap. A $100 gap on a $400 phone is a lot to give away.

How to get the most from a trade-in

1. Get several quotes. Never take the first one. The spread between companies for the same phone is often over $100.
2. Grade honestly. Every buyback company inspects the phone when it arrives. If you say Good and they see Fair, they'll lower the offer, and the new offer is usually worse than if you'd picked Fair to begin with.
3. Unlock it first if you can. If the phone is paid off, your carrier will usually unlock it for free.
4. Sign out of iCloud or your Google account and remove the SIM before you ship. A phone that's still activation locked gets sent back or offered next to nothing.
5. Check how long the quote is good for. Every company locks the price for a limited window, usually a couple of weeks or more. Ship it before that runs out, or you'll get re-quoted at whatever the price is that day.

Common questions

Is it better to trade in or sell my phone myself?

If you want the most money, sell it yourself. The best trade-in offer pays about 69% as much as selling on Swappa after fees. If you want it done today with no hassle, a trade-in is fine, just compare a few offers first.

Which phone buyback company pays the most?

It changes by phone and by day. When I checked unlocked phones this fall, Rick's iStock had the top offer on about half of iPhone configurations, and Gazelle had the top offer on about 40% of Samsung configurations. But a dozen other companies each won somewhere, so no single company wins across the board. That's exactly why we track all of them.

How much less is a trade-in than selling on Swappa?

The median gap is about $89 per phone, or roughly 31% less than what you'd keep on Swappa.

Do buyback companies pay for phones in Fair condition?

Yes, but a lot of them pay much less. Several offer 40% less for Fair than for Good, while Swappa buyers pay almost the same for both.
