eBay Quick Profit Estimator
Enter your purchase price and sold price to estimate profit before shipping. This free eBay reseller profit calculator is built for resellers who source at thrift stores, estate sales, garage sales, and auctions — plug in your numbers before you commit to a purchase, so you know whether an item is actually worth flipping.
Estimate uses a 15% eBay fee. Shipping, taxes, promoted listings, and category differences are not included. This quick estimator is a simplified starting point. For the full picture — real eBay sold comps, sell-through rate, and active competition — try FlipCheck, or read our eBay Buy or Pass Checklist before you source your next lot.
How to Use This Tool
Enter what you paid for the item and the price it sold for. The calculator applies a flat 15% eBay fee and shows your estimated profit. This is a quick gut-check, not a final number — it does not include shipping cost, packaging, or promoted listing fees.
Worked Example
Say you buy a used stand mixer at a thrift store for $12 and resell it on eBay for $85. After the estimated 15% eBay fee (about $12.75), your estimated profit before shipping is roughly $60.25. Once you factor in a $9 shipping cost and a $1.50 box, your real profit lands closer to $50 — still a strong flip, but the fee and shipping bite into more of the margin than most new resellers expect.
What This Estimate Does Not Include
- Actual shipping cost (varies by weight, size, and carrier)
- Packaging and supply costs
- Promoted Listings fees, if used
- Sales tax collected and remitted by eBay
- Category-specific final value fee differences (some categories run higher or lower than 15%)

FAQ
Is the 15% fee accurate for every category?
No. eBay’s final value fee varies by category, typically in the 10-15% range, plus a small per-order fee. Treat 15% as a conservative estimate, not an exact figure.
Does this include shipping cost?
No. Add your actual shipping and packaging cost to this estimate manually to get a realistic profit number.
Should I use this or FlipCheck before buying?
Use this quick estimator once you already know your likely sale price. Use FlipCheck before you buy, to pull real sold comps and judge whether an item is worth sourcing at all.
