Calculate a target value for a custom trading card lot
Build a group from exact cards in your collection or the DeckTradr catalog, save the available market-value snapshot, and apply the percentage that fits the deal you are considering.
Custom lots are available to signed-in users on the web. Open Deals 101, choose Custom Lots, and review every card and value before saving.

Plain answers
Trading card lot calculator questions
Can I calculate the value of a group of trading cards?
Yes. A signed-in DeckTradr user can create a private custom lot on the web, add exact catalog or collection cards, set quantities, and calculate a target as a percentage of the saved market total.
Is the custom trading card lot calculator free?
Yes. The current web custom-lot workspace is available to signed-in DeckTradr users without a paid membership.
Does DeckTradr automatically update a saved lot when card prices change?
No. The lot stores the market values selected when it is created. Review current card evidence again before relying on an older saved lot.
Does marking a lot sold record a sale or change my collection?
No. Marking a custom lot sold changes the lot status. It does not settle payment, create a vendor transaction, or move collection inventory.
Is the lot target a guaranteed offer, appraisal, or tax value?
No. The target is percentage-based decision support using the selected cards and available market evidence. It is not a guaranteed offer, professional appraisal, accounting record, or tax value.
