FAAB calculator: what to bid on waivers this week.
Enter the budget you have left, your league size, the weeks left in the regular season, how much the player is worth and how badly your roster needs the player. The calculator returns a bid, the number to stop at, and the share of your remaining budget it spends. No account needed.
Free includes one league and three personalized decisions each week across Lineups and Ask AVRA. Pro adds more leagues and the complete decision workflows.
Work out your FAAB bid
Set your league up below for a bid you can place today. No account needed.
- Treated as a startable weekly piece, which starts at 15 percent of the budget still available.
- Adjusted for upgrading a spot already covered.
- A 12 team league is the reference size, so no size adjustment applies.
- Mid-season, so the budget is spent at its face value.
This is the general baseline every manager can run on paper. It does not know your roster, the players actually available in your league, or what your league-mates have left to spend. AVRA reads all three once you connect your Sleeper or ESPN league.

Spending is in line with the season. Keep bids near the weekly allowance unless a difference maker shows up.
How much FAAB should I bid
Start from what the player is worth to a lineup. The calculator gives a difference maker 35 percent of the budget you have left, a weekly starter 15 percent, a bye or injury patch 6 percent and a speculative stash 2 percent. It then raises the bid when the player fills an empty starting spot, lowers it when he only adds bench depth, and returns a ceiling at 1.5 times the bid. Above the ceiling, the claim costs more than it returns.
Why league size and weeks left change the bid
A 12 team league is the reference. Each team above or below 12 moves the bid 2.5 percent, because every extra roster is another manager bidding against you. Weeks left matter because FAAB is use-it-or-lose-it: early in the season the calculator holds budget back for later injuries, and in the final weeks leftover budget has almost no use, so the same player is worth a bigger share of what remains.
What is FAAB and why does the bid amount matter
FAAB stands for Free Agent Acquisition Budget: your season-long budget for waiver-wire bids. Win the claim and that money is gone. The Week 4 flier competes with the Week 14 injury replacement you haven't met yet. A bid that is too low loses the player to a rival, and a bid that is too high leaves nothing for the next breakout.
Does this work with my Sleeper or ESPN league
Yes. The calculator works for any league that uses FAAB, on Sleeper, ESPN or anywhere else, because it only needs your numbers. Sleeper's default waivers clear early Wednesday morning and ESPN processes waivers daily from 3 a.m. ET, so place your bid before your league's waiver run.

Frequently asked questions
Is the FAAB calculator free?
Yes. It runs in your browser with no account and no league connection. Enter your budget left, league size, weeks left, the player's tier and your roster need, and it returns a bid and a ceiling.
What does the bid ceiling mean?
The ceiling is 1.5 times the suggested bid, capped at your remaining budget. If the bidding in your league usually goes above that number for a player of this tier, the claim costs more than it is likely to return, and your budget is better saved for the next opening.
Should I bid more FAAB early or late in the season?
Late. With 10 or more weeks left the calculator trims the bid to keep budget for later runs. With fewer than 3 weeks left it raises the bid sharply, because unspent FAAB has almost no remaining use once the regular season ends.
Does the calculator know who is on my waiver wire?
No. It is the general math any manager can run, so it knows only the numbers you enter. It does not read your league, your roster or your rivals' budgets.
