Local cash
Often the cleanest net payout and fastest cash rotation, but it requires safe meetups and enough local demand.
Net payout guide
The highest listing price is not automatically the best exit. A useful comparison includes marketplace fees, payment processing, shipping, return exposure, sale speed, and the time your cash stays tied up.
Fast answer
Often the cleanest net payout and fastest cash rotation, but it requires safe meetups and enough local demand.
Broad buyer reach can move slower inventory, but category fees, shipping, returns, and seller performance affect the result.
A phone-focused audience and transparent fee structure can help, but processing, shipping, and listing requirements still belong in the math.
The formula
Sale price - marketplace fee - payment processing - shipping - packaging - repair or return reserve = estimated net payout.
Estimated net payout - target profit - remaining risk room = maximum buy price.
Use current fee schedules when you run the numbers. eBay explains that its selling fee depends on the category, total sale amount, listing choices, and seller performance. Swappa currently lists a flat sale fee for each party plus applicable payment processing. Those policies can change, so verify them before every shipped-sale estimate.
Hypothetical deal
Imagine a clean used iPhone that can realistically sell for $350. These are teaching scenarios, not current fee quotes or profit promises.
If it sells for $330 locally with no marketplace fee, the net may be close to $330 before travel, meetup, and markdown costs.
If it sells for $350 online, subtract the current platform fee, processing, label, packaging, and a realistic return reserve.
A slightly lower local price can still win when it pays faster and removes shipping and return exposure.
Channel decision
Risk differences
Meet in a monitored public place, keep communication on-platform, and never let urgency replace inspection.
Document condition and identifiers, package carefully, insure appropriately, and follow the marketplace's current seller rules.
A thin-margin shipped deal can turn negative if the device comes back or the listing was not precise.
A smaller margin that rotates quickly can be more useful than a larger theoretical margin that sits for weeks.
Before you calculate
Inspect first. Apple advises buyers not to take ownership of a used iPhone that is protected by Activation Lock. Make sure the device is erased, reaches the Hello/setup flow, and no longer asks for the previous owner's Apple Account.
