Know what your collection is worth — and what it cost you.
Deckbox tracks Magic: The Gathering the way a portfolio deserves: every copy as its own lot, with the price you paid, the price it is worth today, and the gains you have actually realized.
Black Lotus · Limited Edition Alpha
The dashboard
Your collection's balance sheet, priced every day.
One number says what the whole collection is worth today. Under it sits every lot you own — what you paid, what it is worth now, and how far apart those two numbers have drifted.
Sample data — not a real or typical portfolio.
The Vault
Every printing, every finish, counted separately.
Foil and nonfoil, original and reprint — each is its own position with its own price. A first-printing copy worth hundreds never averages itself away against the reprint sitting next to it.
What it tracks
Built on the four things a portfolio needs.
A collection tracker tells you what a card sells for. A portfolio tells you what your copy of it did for you. That difference is the whole product.
Lots
Acquisitions, not averages
Every purchase is its own lot, with its own date and its own price. Sell one copy and the cost basis that leaves with it is the one that actually left.
Cost basis
What you paid, not a guess
Enter the price you paid, or set a lot’s value by hand when there is no market for it. Unrealized gain is measured from your number.
Realized gains
Gains you have booked
When a lot leaves the collection its gain moves from unrealized to realized and stays on the record, instead of quietly vanishing from the total.
Price history
A price for every day
Market prices are captured daily, so the value chart is a record of what happened — not a line recomputed from today every time you open it.
