What to bid, and what it will take to win
A waiver claim in a FAAB league is a blind auction against the same people you drafted against. This prices the whole free-agent pool in your league’s dollars, reads every rival’s remaining budget, and tells you the number.

Your username only. Nothing is sent anywhere — the league is read straight from Sleeper’s public API in your browser.
2. Pick the league
FAAB leagues only — a league on waiver priority has no bid to advise.
3. Which team is yours?
Or enter the league by hand
Not on Sleeper, or running a what-if? Give it the budgets and the wire and it prices the claim the same way. Paste every roster and the wire is exact; skip that and each rival is assumed to have a hole at the position.

How these numbers are made
Rest-of-season is the player’s value on your own cheat sheet, scaled to the weeks that are left: auction dollars at your league’s draft budget, not a generic $200. The other two columns are FAAB dollars. They are different currencies and deliberately not the same scale — a $100 FAAB budget buys a handful of claims, where a $200 draft budget buys a whole roster, so a going rate above the rest-of-season figure is normal rather than a mistake.
What you should bid is not what he is worth. Over the weeks that are left you will make a handful of claims anyway, so the ones you would have made regardless are not what winning this one buys you. The baseline is the first free agent you would not otherwise have taken, and the surplus is the gap up to him — value over replacement, the same idea the draft board is built on, with the replacement drawn off the wire. Ten interchangeable handcuffs all sit at replacement and are worth about a dollar each however good they look on a ranking. One genuinely better player in a thin pool is worth real money. That surplus is then measured against the other claims the same budget still has to cover.
Going rate is the highest bid any rival can rationally justify, computed one rival at a time: their remaining budget, their hole at that position, their alternatives. A leaguemate with $0 left is not competition no matter how badly they need a running back, and this is the only part of the fantasy season where you can see that in advance.
What it does not know. FAAB is blind and people are not rational, so treat the going rate as the middle of a range, not a line. It does not read this week’s matchups, injuries that broke in the last hour, or the fact that your leaguemate drafted the guy’s teammate and is emotional about it. Kickers and defences are left out on purpose.
