Dynasty fantasy baseball, built for fair trades.
FantasyTradeLab is the free home for dynasty managers who care about getting their trades right. Age-weighted player values, calibrated against industry consensus, with zero signup friction.
What FantasyTradeLab stands for.
Four principles that shape every part of the site — from the calculator's transparent formula to the rankings methodology.
Always free
No paywall, no signup, no premium tier hidden behind a registration form. Tools that should be free, are.
Transparent
The dynasty value formula is published in full on the calculator page. You see exactly how every value is calculated.
Calibrated
Cross-checked against industry consensus from RotoProspects, Baseball America, and Imaginary Brick Wall.
Evergreen
Built for long-term dynasty value, not weekly hype cycles. The site stays useful all season — no constant tinkering required.
Built by dynasty players. Not by a media company.
FantasyTradeLab exists because the dynasty fantasy baseball community deserves better than paywalled trade tools and rankings written for clicks. Every design decision — from the soft palette to the transparent value formula to the shareable trade URLs — comes from years of sitting in our own league chats arguing about whether some offer was actually fair.
We built the calculator we wished existed: clean, fast, accurate, and respectful of your time. If our work helps you win a championship, or escape a trade you should have rejected, we've done our job.
