Same price everywhere
The calculator uses one sale price for every marketplace, so you see the fee difference. In practice prices differ: eBay often sells collectibles and electronics higher, Poshmark and Mercari do well with clothing.
Shipping
Shipping charged to the buyer and your label cost apply to eBay, Mercari and Facebook. On Poshmark the buyer pays the prepaid label; a local sale has no shipping.
Profit and ROI
Profit = what you keep − the label − what you paid − other costs. ROI = profit ÷ what you paid.

FAQ
Which marketplace has the lowest fees?
For a local cash sale, none. For shipped sales: Mercari and Facebook Marketplace take 10%, eBay 13.6% plus $0.40 per order in most categories, Poshmark 20% (or $2.95 under $15). Lowest fee isn't always most profit — the price you get matters more.
How do I calculate profit on a flip?
Sale price + shipping charged, minus the marketplace fee, minus the shipping label, minus what you paid and other costs (packaging, gas). That is your profit; divide it by what you paid for your ROI.
What ROI should a reseller aim for?
Many aim for 100% or more on cheap items — you double your money — and accept less on expensive items that sell fast. Count your time too: a $5 profit that takes an hour to list and ship is rarely worth it.
Can FlipTip calculate this for me?
Yes, from a photo: it identifies the item, finds what it actually sold for, and shows your profit after the fee of the marketplace you sell on, the most to pay and a buy-or-skip verdict.
