Tracking Card Value and Pack ROI

Whether you crack packs for fun or collect with an eye on value, the question is always the same: is what you are pulling worth what you are paying? This tracker prices your cards, follows your collection over time, and estimates the expected return of a sealed pack so you can make informed decisions instead of chasing losses.

How this calculator works

Select a set and the tool shows current pricing across rarity tiers, calculates the expected value of a pack, and lets you log cards into a portfolio you can track over time.

The math behind pack ROI

The expected value of a pack is the sum of every possible card's market price multiplied by how often it appears. If a set has one chase card worth a lot but pulled rarely, and many commons worth little, the expected value is a weighted blend of all of them. Compare that expected value to the pack price and you can see, on average, whether opening packs gains or loses money. Individual packs will swing wildly, but over many packs the expected value is what you trend toward.

Worked example

Imagine a set where the average pack contains commons and rares worth a small amount, with a small chance at a high-value secret rare.

The everyday cards might average a modest value per pack on their own.
The rare chance at a big hit adds a fraction of that card's price to the expected value.
If the combined expected value sits below the pack price, buying singles of the cards you actually want is usually the smarter play.

How to use it

Choose the set you are opening or collecting.
Review the expected value against the current pack price.
Log your pulls into the portfolio to track total value.
Revisit later to see how your collection has appreciated or dipped.

Tips

If you only want one specific card, buying the single almost always beats gambling on packs.
Prices move with the competitive meta; a card can spike when it becomes tournament-relevant.
Track sealed product too, since some sets gain value once they leave print.
