A trade tool for multi-team fantasy football deals, built because every calculator on the internet stops at two teams and none of them tell you how to actually get the player you want.
Last updated September 2026
Roundtable does two things. The trade table lets you build a deal between two, three, four or five teams, assign each player a destination, and see what every side gains or loses — with the reasoning shown rather than hidden. The trade assistant works the other way round: you name a player you want, and it searches your roster for the cheapest package the person who owns him is likely to accept.
Both run entirely in your browser. There is no account, and your league data is never uploaded anywhere.
Recent form never changes a player's price. Market values already move with production, and counting a good game twice would inflate everything. Form is used only to read the other manager — how attached they are likely to be, and whether now is a sensible week to ask.
Market values refresh automatically in the background and are stored locally between visits so the tool loads instantly. The indicator at the top of the page shows how long ago the last refresh was, and clicking it pulls fresh numbers immediately. There is nothing to maintain and no version to keep up with.
The full explanation lives on its own page: how the model works. The short version is that it prices the best player in a deal above the sum of the parts, charges for the roster spots a package consumes, and checks what a trade does to the lineup you can actually field — rather than adding up two columns and declaring a winner.
Roundtable was built by a fantasy manager who got tired of arguing about three-way trades with a calculator that only understood two teams. It is a small independent project, not a company, and it is not affiliated with the NFL, the NFLPA, any fantasy platform or FantasyCalc.
Corrections, bugs and disagreements about the model are all welcome — particularly disagreements, which is how the settings got as flexible as they are. Email hello@roundtabletrades.com and you will get a reply from a person.
