Galaxy S10e, 128GB, Unlocked resale price

Back Market carries the higher price today at $127 against $100 on Swappa. Headline price is not the same as what you keep, because every marketplace takes a different cut. Applying our default all-in selling-cost profile:

Estimates using default assumptions, not your actual fee tier. Speed matters too: a higher price you wait six weeks for can be worth less than a lower one that moves this week.

Work backwards from the sell side rather than forwards from the asking price. At today's best price of $127, estimated selling costs of about $18.70 leave you roughly $108.30. If you want $50 of profit on the flip, your maximum buy price is about $58. Pay more than that and the profit is gone before you start.

That is the whole job, and it changes daily as prices move. Set your own fee tier, shipping, prep and repair costs and target margin, and the Recommended Max Buy Price is calculated for you on every device.

On the latest snapshot it listed from $100 to $127 in 128GB, Good, Unlocked. Those are current asking prices on the lowest qualified listing per marketplace, not completed sales, and they refresh daily. Trade-in and buyback services will quote you materially less, because they are buying to resell at these prices.

Generally yes, because the buyer pool is larger and the device works on any network. How much more depends on the model and the carrier, and it moves. We price unlocked and each carrier lock as separate configurations rather than averaging them, so the gap is a number you can look up rather than a rule of thumb.

This configuration moved +10.9% over the last 30 days, with a current modelled value of $121.99. Depreciation is calculated per exact configuration rather than per model line, because storage tiers and conditions move at different speeds.

Different fee structures, different buyer protection, and different inventory. A certified refurbished unit with a warranty is not the same product as a private sale, so a gap is normal rather than an error. The spread between them is where a flip lives.

Publicly listed prices collected daily from tracked resale marketplaces and direct buyers, matched on exact model, storage, condition and carrier lock. Listings more than 25 percent from the peer median are excluded before any figure is calculated, nothing older than 24 hours contributes, and dealer bids are never pooled with marketplace asking prices.
