Among Us Impostor Odds Calculator
Calculate your odds of being an impostor and the probability that a random ejection vote actually catches one.
About the Among Us Impostor Odds Calculator
In Among Us, impostor roles are assigned randomly at the start of each match, so your odds of being an impostor are simply the number of impostors divided by the total player count. Once the round is underway, crewmates without any real evidence are often left guessing at ejection votes — this calculator turns those hunches into real probabilities.
Formula: Impostor Chance = Impostors ÷ Total Players. Blind Vote Chance = Impostors ÷ (Total Players − 1), since a crewmate wouldn't vote for themselves. All-Impostors Chance = 1 ÷ C(Total Players − 1, Impostors), using the combination formula for picking every impostor correctly in one blind guess.
The numbers make an important point: with more impostors relative to the lobby size, a single random ejection becomes a much better bet, while correctly identifying every impostor purely by guesswork gets astronomically unlikely as the lobby grows — exactly why gathering real evidence matters far more than voting on a hunch.
