If you've got a Galaxy S24 and you're thinking about selling, here's what it's worth this fall. These are real prices from the marketplaces and buyback companies I track every day, not a trade-in quote built to sell you a new phone.
The short version: sell it yourself. On the iPhone 16, the best buyback offer comes close to what you'd keep on Swappa. On the S24 lineup it isn't close. You leave $55 to $132 on the table by taking the easy offer.
Quick answer
In Good condition and unlocked, base storage:
- Galaxy S24 (128GB): about $296 on the used market, $299 on Swappa, $216 best buyback offer
- Galaxy S24 Plus (256GB): about $370, $370 on Swappa, $240 best buyback offer
- Galaxy S24 Ultra (256GB): about $525, $500 on Swappa, $370 best buyback offer
- Galaxy S24 FE (128GB): about $273, $268 on Swappa, $166 best buyback offer
What the numbers mean
Used market is the median across the 3 or 4 marketplaces with a price that day. Many of those sellers are refurbishers with warranties, so this is closer to what a buyer pays than what you'd get.
Swappa listing is the price a buyer sees on Swappa, including their 3% buyer fee.
Swappa after fees is what you'd keep from that sale. Swappa takes 3% of your asking price, and PayPal takes 3.49% plus $0.49 of the order. That's a little over 9% of the listed price, before shipping. I break this down in what you actually keep when you sell.
Best buyback offer is the highest offer I found from the 10 or 11 buyback companies quoting each phone.
Galaxy S24 prices by storage
All prices are Good condition, unlocked.
| Storage | Used market | Swappa listing | Swappa after fees | Best buyback offer |
|---|---|---|---|---|
| 128GB | $296 | $299 | $271 | $216 |
| 256GB | $374 | $389 | $352 | $233 |
The 256GB Swappa price comes from only 4 listings, so treat it as a rough number. I didn't find enough 512GB listings to price that one.
Galaxy S24 Plus prices by storage
| Storage | Used market | Swappa listing | Swappa after fees | Best buyback offer |
|---|---|---|---|---|
| 256GB | $370 | $370 | $335 | $240 |
| 512GB | $411 | $411 | $372 | $275 |
Galaxy S24 Ultra prices by storage
| Storage | Used market | Swappa listing | Swappa after fees | Best buyback offer |
|---|---|---|---|---|
| 256GB | $525 | $500 | $453 | $370 |
| 512GB | $568 | $576 | $522 | $390 |
| 1TB | $645 | $644 | $584 | $365 |
Only one buyback company quoted the 1TB Ultra, which is why its offer is lower than the 512GB. Don't read much into it.
Storage barely pays here. The 1TB Ultra cost $360 more than the 256GB at launch. Used, the gap is about $120.
Galaxy S24 FE prices
At 128GB, the FE is about $273 on the used market, $268 on Swappa ($243 after fees), and $166 from the best buyback offer. There were only 4 Swappa listings, though. The 256GB FE is too thin to price: three marketplaces had a single listing each, and they were hundreds of dollars apart.
Sell it yourself or take the buyback?

This one's easy. On every S24 model with solid data, Swappa after fees beats the best buyback offer by at least $55. On the Ultra 512GB it's $132. That's worth an hour of listing and a trip to the post office.
Why the gap? Buyback companies have to resell your phone with room for profit, and on these Samsung models they're leaving themselves a lot of room. The iPhone math is different, which I cover in trade-in vs selling yourself.
One warning: a buyback offer depends on the phone passing their inspection, so if you do go that route, grade your condition carefully.
How condition changes the price
The tables are all Good condition. Across the S24 lineup:
- Mint usually sells for about 4% to 14% more on the marketplaces, and gets 12% to 25% more from the best buyback offer.
- Fair usually sells for about 5% to 16% less on the marketplaces. The best buyback offer drops only about 4% to 5% on most models, but about 25% on the S24 Plus and the 256GB S24.

Is now a good time to sell?

The base S24 has bounced between about $305 and $340 since May, and it's sitting at the bottom of that range now. The Ultra has slid slowly, from about $585 in May to about $530. The Plus held near $400 to $415 all summer, then dropped to about $365 starting around the end of September.
None of these lines are going up. If you're done with your S24, I wouldn't wait for a better price.
For scale, the S24 models hold about 37% to 42% of their launch price at a little under three years old. The iPhone 15, at about three years old, holds around 50%. Samsung phones lose value faster, which I dig into in how fast Samsung phones lose value.
Things that knock the price down
- A carrier lock. On most S24 models the best locked offer was only a few percent lower, but on the S24 Plus it dropped 16% to 30%. Details in locked vs unlocked prices.
- Screen burn-in. Buyers check for it on older Samsung displays, so look at a plain gray screen before you list.
- A cracked screen or back. That's a damaged phone, not a Fair one, and it's priced very differently.
- Account locks. Remove your Google and Samsung accounts and factory reset before you sell.
