From the resale workshop
The calculation bench
Supply current fees and your own costs. The counter does not know a marketplace’s rules for your account.
Resale profit & ROI
Count fees, shipping and the time you spend on a sale. Use the marketplace's actual fee basis and adjust your input if its rules differ from this simplified model.
Editable fee comparison
Compare two hypothetical fee structures using current quotes or official seller terms. Both rates start blank: this site does not publish marketplace fee rates.
Minimum sale-price planner
Work backward from all non-fee costs and your chosen profit target. This does not establish what a buyer will pay.
Before-you-buy sourcing checklist
A local-only inspection aid. All boxes checked does not establish safety, authenticity or legal saleability.
