How it works

Use realistic costs—not just purchase price versus resale.

The calculator subtracts acquisition costs, selling fees, preparation expenses, and outbound shipping. ROI compares profit with the cash invested in the deal.

Estimated profit

Resale price minus every cost entered.

ROI

Estimated profit divided by cash invested.

Maximum purchase price

The lower price allowed by your minimum profit and minimum ROI targets.

Research estimate

Actual selling fees, taxes, returns, shipping, condition, and resale prices can differ. Use this calculator as a sourcing aid, not a guarantee.
