Free fantasy trade calculator: compare projected points side-by-side, get a fairness % and plain-English verdict. Fast, free, no signup.
Projections are supplied by you — the math is only as good as the numbers you enter. Use rest-of-season projections for the fairest comparison.
Is the trade fair? Our free fantasy trade calculator ends the group-chat argument in seconds. Enter the players or picks on Side A and Side B — up to four each — with your projected points, and it totals each side, computes the point differential, a fairness percentage, and a plain-English verdict like “Side A wins by ~12 points — fairly even”.
Every fantasy trade is really a question of expected value: which side projects to score more points? League platforms publish rest-of-season projections for every player, so you don’t need to guess — add them up and compare. That aggregate comparison is exactly what this calculator automates.
Raw totals alone can mislead when the packages differ in size, so the tool also computes a fairness percentage: the weaker side’s total divided by the stronger side’s total, × 100. A 90%+ trade is essentially even; below ~55% it’s lopsided. The verdict tiers make the number instantly readable.
One caveat the numbers can’t capture: roster context. Two-for-one trades free a bench spot, and trading a star from a position of depth has an opportunity cost. Use the math as the core of your argument — then adjust for your roster reality.
Side total = sum of projected points on that side
Differential = Side A total − Side B total
Fairness % = (weaker side total ÷ stronger side total) × 100
Worked example: Side A: Justin Jefferson (285) + Isiah Pacheco (175) = 460. Side B: Amon-Ra St. Brown (265) + David Montgomery (180) = 445. Differential = 460 − 445 = +15 for Side A. Fairness = 445 ÷ 460 × 100 = 96.7% — very even, basically a coin flip. Verdict: “Side A wins by ~15 projected points — a very even deal.”
Verdict tiers: ≥90% very even · 75–90% fairly even · 55–75% one side clearly better · <55% lopsided.
Your leaguemate offers CeeDee Lamb (290) straight up for your Tee Higgins (190) plus a 1st-round pick you value at 60 projected points of a replacement player: Side A = 290, Side B = 190 + 60 = 250. Differential = +40 for Side A; fairness = 250 ÷ 290 × 100 = 86.2% — fairly even. The calculator says defensible, not a steal — so you counter by asking for a throw-in bench player worth ~40 points to close the gap.

This page is a free fantasy trade calculator on Sigma Calculator (sigmacalculator.net) that evaluates fantasy sports trades: up to 4 named entries per side (Side A / Side B) with user-supplied projected points; it computes side totals, point differential, fairness % (weaker side total ÷ stronger side total × 100), and a plain-English verdict with tiers (≥90% very even, 75–90% fairly even, 55–75% one side better, <55% lopsided). Pure arithmetic — projections are user-supplied, no medical or financial content.
A fair trade is one where both sides project to score a similar number of points — a fairness % of 90% or higher is essentially even. Most accepted trades fall between 75–90% fairness, where one side gains a small edge but both managers get what they need.
Value picks in projected points: estimate what the pick will realistically turn into (e.g., a 1st-round rookie pick ≈ the projection of a typical rookie starter, often 100–150 points in redraft formats). Dynasty leagues value picks higher. Enter that number as one of your 4 entries per side.
Rest-of-season projections. Season totals include games already played, which neither side benefits from. Your league platform (ESPN, Yahoo, Sleeper) publishes ROS projections — use those for every player in the trade.
Yes. Enter up to 4 entries per side, so a 2-for-1 (or any imbalance up to 4-vs-4) works naturally. The fairness % handles unequal package sizes by dividing the weaker total by the stronger total — but remember a 2-for-1 also frees a roster spot, which has real value the math doesn’t capture.
Fairness % = weaker side’s projected total ÷ stronger side’s total × 100. 100% is a perfect wash; 90%+ is very even; 75–90% fairly even; 55–75% one side clearly better; below 55% is lopsided. It measures relative balance, not absolute quality.
