How is reselling profit calculated?
Profit is what remains of the sale price after three deductions: marketplace fees (the platform’s cut of what the buyer pays), shipping and supplies you pay for, and the item’s cost to you. Margin — profit as a share of the sale price — tells you how efficient the flip was; ROI — profit as a share of your buy cost — tells you how hard your sourcing dollars worked. The platform choice changes the answer more than most sellers expect, because fee schedules in 2026 range from 0% (Facebook local pickup) to 20% (Poshmark).

Worked example: the same $40 flip on four platforms
You paid $10 at a thrift store and the buyer pays $40 total; your label costs $5 (except Poshmark, where the buyer covers shipping). eBay: fees 13.6% × $40 + $0.40 = $5.84 → profit $19.16 (48% margin). Facebook shipped: 10% × $40 = $4.00 → profit $21.00. Facebook local pickup: no fee, no label → profit $30.00. Mercari: 10% × $40 = $4.00 → profit $21.00. Poshmark: 20% × $40 = $8.00, but $0 shipping → profit $22.00. Same item, same buyer price — profits spread across an $11 range purely on fee structure.
Reselling profit FAQ
How do you calculate reselling profit?
Profit = sale price − marketplace fees − shipping cost − what you paid for the item. Margin is profit divided by sale price; ROI is profit divided by your buy cost. A $10 thrift find that sells for $40 on eBay incurs about $5.84 in fees (13.6% + $0.40); after a $5 label, profit is $19.16 — a 48% margin and 192% ROI. Resellers who skip the fee line are the ones surprised at payout time.
What fees does each reselling platform charge in 2026?
eBay: 13.6% final value fee in most categories plus a $0.30–$0.40 per-order fee. Facebook Marketplace: 10% ($0.80 minimum) on shipped orders, nothing on local pickup. Mercari: a flat 10% selling fee on item price plus buyer-paid shipping, with no separate payment-processing fee. Poshmark: a flat $2.95 on sales under $15 and 20% on sales of $15 or more. All rates verified against each platform’s official fee page in August 2026.
Which reselling platform has the lowest fees?
Facebook Marketplace local pickup is the only zero-fee option. For shipped items, Facebook and Mercari tie at 10%, eBay runs about 14% all-in (13.6% + $0.40), and Poshmark is the most expensive at 20% — though Poshmark provides the prepaid shipping label, which the buyer pays for, so seller-side shipping cost is usually $0 there. Lowest fee is not the same as highest profit: eBay’s larger buyer pool often produces a higher sale price that more than covers the extra 4%.
What is a good profit margin for reselling?
Most experienced resellers target at least a 50% ROI on shipped items after fees and shipping, and many aim to triple their money on thrift-store finds ("buy for $10, sell for $30+"). Margins on free items — decluttering your own home — are effectively infinite, which is why selling what you already own is the highest-ROI reselling there is.
Do I pay taxes on reselling profit?
Marketplaces issue Form 1099-K once your sales cross the IRS reporting threshold, but tax is owed on profit, not gross sales — you subtract what you originally paid for items plus fees and shipping. Personal items sold for less than you paid for them generally produce no taxable gain. Keep records of buy costs and fees; this calculator’s breakdown maps directly to those deductions. (Not tax advice — a tax professional can confirm your situation.)
How should I price an item to hit a target profit?
Work backwards from real sold prices, not from your costs. Look up what identical items actually sold for, then run that price through this calculator to see whether the profit clears your threshold — if it does not, the item is not worth listing on that platform at that price. Pricing from asking prices instead of sold data is the most common way resellers overestimate profit before fees.
