Definition
Plus money is a positive American odds price, shown with a plus sign, such as +150 or +220. It means the potential profit is larger than the amount staked. For positive American odds, profit equals:
stake × (odds / 100)
Implied probability equals:
100 / (odds + 100)
A +150 price implies a 40.00% break-even probability because 100 / (150 + 100) = 0.40.
Worked Example
If a bettor stakes $100 at +150, the profit is:
$100 × (150 / 100) = $150
The total return is the original $100 stake plus $150 profit, or $250 total.
If the same bettor stakes $40 at +150, the profit is:
$40 × 1.5 = $60
The total return is $100.
Why It Matters
Plus money helps a bettor compare whether the payout is high enough for the true chance of an outcome. If a bettor estimates a +150 outcome has better than a 40.00% chance to win, the price is above its break-even point before accounting for limits, liquidity, and sportsbook hold.
