OddsCalc
From American odds to dollars and probability.
Positive odds (+150) mean 'bet $100 to win $150 profit,' while negative odds (-110) mean 'bet $110 to win $100 profit' — converting to decimal odds (divide by 100, add 1 for positive; divide 100 by the absolute value, add 1 for negative) makes the math straightforward.
Implied probability tells you what win percentage the odds assume — but sportsbooks set odds so the implied probabilities of all outcomes sum to more than 100%, and that gap (the 'vig' or 'juice') is how they make money.
