ESPN Trade Calculator

Note: The ESPN API is a pile of garbage. For some leagues, it won’t let you access the teams on the back end even if you have the SWID and espn_s2 numbers. I wish ESPN was as good as Sleeper in this area but they just aren’t. If you’re hitting an error then it likely means your league just can’t be accessed. If that’s the case, you can either use the google sheet trade calculator or the simple trade calculator. The Google Sheet one will let you input the teams and then try trades that take your team into account. The Simple one is just straight up who wins the trade. That one’s easier if you want a quick answer. The Google Sheet one will take longer to set up, but give a more accurate analysis since it takes your team into account.
