Start Tracking FreeFrequently Asked Questions
What is booster box expected value (EV)?
Expected value (EV) estimates the average dollar value of cards you'd pull from a sealed booster box. SpellBook Finance calculates EV for every in-print set using live TCGPlayer pricing, broken down by rarity and treatment.
How does SpellBook calculate EV differently?
SpellBook uses eBay completed sale data, the prices cards actually sold for, rather than TCGPlayer listing medians. Listing prices skew high because unsold cards stay listed indefinitely.
What is SpellBook Finance?
SpellBook Finance is an MTG portfolio tracker that treats Magic: The Gathering cards and sealed product as financial assets. You can track singles and booster boxes, view price history, and benchmark your collection's performance against the S&P 500.
Can I compare my MTG collection to the stock market?
Yes. SpellBook Finance is the only MTG platform that lets you overlay your portfolio's returns against the S&P 500 index, so you can see whether your cards are outperforming traditional investments.
Is SpellBook Finance free?
SpellBook Finance offers a free tier for tracking card prices, portfolio holdings, and basic price history. Premium features like backtesting, EV rankings, and AI-powered market intelligence are available on the paid plan.
