Enter both sides of any trade — players and picks — and see who wins, by how much, and why. Free, no signup.
In dynasty fantasy football, your roster carries over from season to season, so every trade is really a bet on the next 2–3 years, not just this Sunday. A dynasty trade calculator turns that bet into numbers: every player and every future draft pick is assigned a value that reflects talent, age, and position scarcity. Add what you're giving and what you're receiving, and you immediately see whether the deal is fair — and which side should be asking for more.
The RosterWorth dynasty trade calculator above is free, works without an account, and supports both 1QB and superflex/2QB league formats. It handles multi-player trades, 2-for-1s, and pick-heavy rebuild moves, and every verdict comes with a plain-English explanation, not just a number.
Test the same trade on six popular calculators and you can easily get three different answers — because most tools hide their math. RosterWorth publishes the formula: value = ranking curve × age factor. When the calculator says you lose a trade by 12%, you can see exactly which asset created the gap.
Use the number as a second opinion, not a verdict from the sky. If your league mate is desperate for a running back, the market inside your league is the real market — the calculator just keeps you from giving away the farm.

Most dynasty trade calculators ask you to trust a black box: a number appears, and you're supposed to accept it. We built RosterWorth around a different idea — every value on the board should be explainable. Each player's value is a published formula (consensus ranking curve × age factor, adjusted for 1QB or superflex), so when a trade grades as a 12% loss, you can trace exactly which asset created the gap.
That transparency matters because the market itself disagrees. Run one realistic trade through KeepTradeCut, FantasyCalc, and DynastyProcess and you'll regularly see a fair deal turn into a landslide in either direction. When tools disagree that much, the honest answer is to show your work — and to remind you that a calculator is a second opinion, not a league office ruling. For a side-by-side look at how the major tools differ, see our best dynasty trade calculators comparison.
RosterWorth also covers the parts of a dynasty trade other calculators treat as afterthoughts: future draft picks are valued with early, mid, and late round tiers (so a 2027 first is not a mystery box), multi-player and pick-heavy deals are graded in one pass, and every verdict includes the average age of each side — because trading a 24-year-old core for a 29-year-old core is a different decision even when the totals match.
If you're tearing down a roster, the question is never "is this trade fair" — it's "how many first-round picks is my star actually worth." Add your veteran to one side and stack early, mid, and late firsts on the other until the bars level out. Our rebuild trade guide walks through the full teardown playbook.
Chasing a title? Flip the exercise: put the aging veteran on your side and see what a fair return looks like before you ship a future first. The superflex toggle re-prices quarterbacks automatically, so 2QB league trades grade on the right curve. The superflex trade calculator page explains the QB premium in detail.
A dynasty trade calculator compares the two sides of a fantasy football trade using player values that account for talent, age, and position scarcity in dynasty leagues, where rosters carry over year to year. It tells you whether the trade is fair, or which side is winning.
Every player and draft pick gets a RosterWorth Index value: a consensus ranking curve multiplied by an age factor. Add the assets each side gives and receives, and the calculator sums both sides, shows the percentage gap, and explains the result in plain language.
No calculator is a final answer — the same trade can grade differently across six popular tools. RosterWorth shows you exactly how each value is built so you can judge the trade yourself instead of trusting a black box.
Values are recalibrated weekly during the NFL season (September through January) and every 2–4 weeks in the offseason, tracking consensus rankings after games, injuries, and depth-chart changes.
Yes. Toggle between 1QB and Superflex/2QB formats at the top of the calculator — quarterback values rise significantly in superflex leagues.
Compare the veteran's value against the pick's value (early, mid, and late first-round picks are all in the picks list). The verdict also factors average age, so you can see whether the deal fits a rebuild or a win-now push.
Yes — the calculator is completely free with no signup and no limits. Search players and picks, grade as many trades as you like, and copy the verdict into your league chat. A paid tier for league imports and extra analytics may come later, but the core trade analyzer stays free.
The values are built for dynasty, where rosters carry over and age matters. In keeper leagues with light keeper rules it works reasonably well as a fantasy football trade analyzer; in single-season redraft leagues, age should matter far less, so weight this season's production more heavily than the calculator does.
