How accurate are the playoff odds?

They are Monte Carlo estimates from 10,000 simulated seasons using current rosters, projections, and your real remaining schedule. They cannot foresee next week's breakout or a trade you have not made yet; they are an honest accounting of the season as it stands today.

Is the playoff odds calculator free?

Yes. Playoff odds are free and do not require an account. Enter your Sleeper username and pick a league.

When do the odds update?

The simulation runs on the latest Sleeper data whenever you open the Outlook tab, and each completed week is stamped so odds movement is tracked week over week across the season.

Does it work for Chopped and guillotine leagues?

Yes. Survivor formats where the lowest scorer is eliminated each week get weekly survival odds and a projected finish instead of a playoff bracket.

How the playoff odds are calculated

The simulator projects every remaining matchup using each roster's projected starters under your league's exact scoring, then plays the rest of the season out 10,000 times, tracking who makes the playoffs, how they seed, and who wins it all in each run. Your playoff percentage is simply the share of simulated seasons where you get in. No power-ranking hand-waving, just the schedule and the rosters, run to exhaustion.

Watch the odds move week to week

Each week's odds are stamped when the week goes final, so your season keeps its receipts: a sparkline shows your playoff odds walking up or down, and the movement view ties the change to the results that caused it. Sunday's collapse and Monday night's miracle both end up on the chart, exactly as they happened.

Play the schedule, not just the matchup

Remaining strength of schedule and week leverage show where your season will actually be decided. A must-win week against the top seed reads differently from a coast week against the basement, and knowing which weeks move your odds most tells you when to push your bench, your bids, and your trades in.
