Asking prices show what sellers want. Completed sales are a better starting point for realistic estimates.
Work backward from the profit you want instead of guessing a listing price. Adjust the target margin to see how fees and shipping change the number.
This is an estimate for research and planning, not a formal appraisal, tax calculation, or guarantee of a sale price.
Calculate a target listing price for an antique based on your costs, marketplace fees, shipping, and desired profit 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.
Start with completed comparable sales, then account for condition, provenance, rarity, platform fees, shipping, and the time you will spend selling it.
Markup is profit divided by cost. Margin is profit divided by the sale price. This tool uses target margin because it reflects the percentage of the final sale you keep.
Some sellers leave room for offers or negotiation. If you do, make sure the higher price remains realistic for the category and condition.
