Use completed sales
Asking prices show what sellers want. Completed sales are a better starting point for realistic estimates.
Quickly check whether a vintage find is worth buying, cleaning, photographing, listing, and storing before you commit your money.
This is an estimate for research and planning, not a formal appraisal, tax calculation, or guarantee of a sale price.
Calculate the likely profit and ROI on an antique or vintage flip after fees, shipping, restoration, and selling costs. Plan your resale with a clearer margin. Start with realistic completed-sale prices and include costs that are easy to overlook. For antiques, condition, authenticity, provenance, maker, rarity, and local demand can matter more than a simple formula.

Shipping, packaging, restoration, platform fees, transport, storage, and your time can change the outcome.
Use this result as a first pass, then verify marks, condition, comparable items, and current marketplace rules.
Include acquisition cost, platform fees, shipping materials, delivery, cleaning, restoration, storage, and a realistic allowance for returns or discounts.
ROI compares your net profit with the money spent to acquire the item. It helps compare opportunities with different purchase prices.
Use completed comparable sales when possible. Asking prices show what sellers hope to receive, not necessarily what buyers paid.
