The DynastyDaily MLB trade calculator prices every hitter and pitcher for dynasty fantasy baseball, then tells you which side of a deal wins and by how much. It covers Roto 5×5, points and 6×6 category formats across 10-, 12-, 14- and 16-team leagues, with pitcher aging curves applied so you never overpay for arms entering their decline years.

Values are built for keeper and dynasty baseball, where a 24-year-old with six controllable seasons is worth far more than a 33-year-old on the same season projection. Enter the players and picks each side sends and the calculator returns a fairness score, a value differential and a plain-English verdict on the trade.

MLB trade calculator — frequently asked questions

How does a dynasty MLB trade calculator work?

Each hitter, pitcher and draft pick gets one dynasty trade value based on projected multi-year production, age and position scarcity. The calculator sums both sides of the deal, favours the higher total, and turns the gap into a fairness score out of 100.

Does the MLB trade calculator adjust for scoring format?

Yes. Roto 5×5 rewards balanced category hitters and closers for saves, points leagues favour high-volume bats and strikeout pitchers, and 6×6 adds categories like OPS and quality starts. Switch formats to reprice the same players for your league.

How are aging pitchers valued in dynasty baseball?

Starting pitchers are discounted as they approach 28-30, where velocity decline and injury risk usually begin, so a mid-30s ace is worth less than his ratios suggest. Young, controllable arms with strikeout upside carry the highest value.

Is the MLB trade calculator free?

Yes — it is free with no sign-in required. Pair it with our MLB dynasty rankings and rookie pick values for full context before you send an offer.
