Formula
For favorites (negative odds): decimal = 1 + (100 / |moneyline|)
For underdogs (positive odds): decimal = 1 + (moneyline / 100)
Implied probability (favorite) = |moneyline| / (|moneyline| + 100)
Implied probability (underdog) = 100 / (moneyline + 100)
Payout = stake × decimal odds
Profit = payout − stake
Full Description
Moneyline odds express profit relative to a fixed stake (usually $100). Negative odds indicate the stake required to win $100; positive odds indicate the profit for a $100 stake. Converting to implied probability provides intuitive understanding of the bookmaker’s expectation.
Frequently Asked Questions
Can moneyline odds be zero?
No. Zero odds are undefined. Use positive or negative integers.
How do I compare two moneylines?
Convert both to implied probabilities. The lower the probability, the higher the potential return but the lower the win likelihood.
Does the stake include profit?
Payout includes both stake and profit. Profit equals payout minus stake.
