Riftbound card investment calculator.
updated Aug 28, 2026
Put an amount into a card or a whole set, pick when, and see what it would be worth today after the fees you actually pay to sell. Nothing here is projected forwards. A card that went up is not evidence that cards go up, so the answer here is only ever what this one did.
Why the fees are the whole point
Every return you read about a card is a gross return. eBay takes 13.35% plus $0.40 of the final price including what the buyer paid for postage, TCGplayer takes 10.25% plus $0.30, and grading starts at $79.99 a card before you post anything and climbs with what the card is worth. On a card that doubled that is the difference between a good year and a flat one, and on a card that rose 20% it is the whole gain. The default here is eBay because that is where most singles actually change hands.
Where the numbers come from
Cards are priced on completed sales, monthly, which is what draws the price history on every card page. Where a card has no long sold history the run falls back to our own record of TCGplayer's market price. The two are never averaged, because they are different marketplaces and the gap between them is real, and neither reaches further back than the set the card came out in.
A set is measured on its median card rather than its total. A set total is one chase card wearing the set's name, and it tells you nothing about the copy you can afford. If the run starts later than you asked for, the card's history simply does not reach that far back, and the page says so rather than filling in a price nobody recorded.
What this cannot tell you
It cannot tell you what happens next. A set that rose over a window is a fact about that window, not a rate that continues, and the sets that fell hardest were usually the ones everybody was sure about when they came out. What a backtest is good for is killing the stories that are simply false, and the trends page holds the rest of them.
