This is an estimate tool. Real outcomes depend on discounts, promoted listing spend, label costs, taxes, and what the marketplace actually charged on the sale.

Know the deal before you commit.

The calculator focuses on the numbers that usually change the outcome: item cost, selling price, shipping, platform fees, payment fees, and extra handling costs.

Use it while sourcing Check whether a thrift or clearance find still leaves room for profit.
Use it while listing Test offers and pricing before you accept thinner margins by accident.
Use presets first Start with eBay, Poshmark, Mercari, or Facebook and then edit as needed.
Track the real outcome later FlipFinds is where you keep the actual item, not just this estimate.
