How to use this calculator
Negative American odds show the stake needed to profit $100. Positive odds show the profit from a $100 stake. This calculator works for any stake amount.
- 1
Select whether you are betting on the favourite (negative odds) or underdog (positive odds).
- 2
Enter the odds value as a positive number (e.g. enter 150 for both +150 and -150).
- 3
Enter your stake amount.
- 4
Read your potential profit, total return, and the implied probability in the odds.
Frequently asked questions
What formulas does this tool use?
For an underdog (+) price, profit = stake × odds ÷ 100. For a favourite (−) price, profit = stake ÷ (odds ÷ 100). Total return is stake plus profit. +150 on $100 profits $150.00, and −150 on $75 profits $50.00.
Do I type the minus sign for favourites?
Pick “Favourite” in the selector and type the size, such as 150. If you type −150 the tool uses the size and ignores the sign, because the selector decides the direction. Odds of zero return a message asking for American odds.
Is the stake included in the total return?
Yes. Total return = stake + profit. At +150 a $100 stake shows a $150.00 profit and a $250.00 return. These are the figures for a winning result only. A losing result returns nothing.
What are implied probability and breakeven win rate?
Implied probability is 100 ÷ (odds + 100) for underdogs and odds ÷ (odds + 100) for favourites. The breakeven win rate is stake ÷ total return. The two come out identical, 40.0% at +150 and 52.4% at −110, because for a single price they are the same quantity written two ways.
Does the tool accept any positive odds value?
Yes, it will compute with any positive number, for example 50 as an underdog price. Published American prices are 100 or more in size, so values under 100 do not occur in practice. The tool does not warn about them.
What does a zero stake do?
The profit and return are $0.00 and the breakeven win rate shows 0.0% (there is nothing staked to recover). Implied probability and decimal odds still show, since they depend on the price alone.
What does it not cover?
Pushes, voids, cash-out offers, bonuses, taxes and multi-leg bets are not modelled. For several legs at once use a parlay calculator. Betting involves a risk of losing the stake, and the legal status depends on where you live.
Moneyline payout calculator for American odds
Reading the two directions
American moneyline prices are quoted against a $100 reference. A positive number is the profit on a $100 stake, so +150 pays $150 of profit. A negative number is the stake needed to make $100 of profit, so −150 needs $150 staked for $100 of profit. This calculator scales both to any stake, and reports profit, total return, the implied probability of the price and the decimal equivalent.
| Direction | Profit | Implied probability | Decimal odds |
|---|---|---|---|
| Underdog +N | Stake × N ÷ 100 | 100 ÷ (N + 100) | N ÷ 100 + 1 |
| Favourite −N | Stake ÷ (N ÷ 100) | N ÷ (N + 100) | 100 ÷ N + 1 |
Worked examples: underdog and favourite
A $100 stake at +150 yields a profit of $150.00 and a total return of $250.00, with an implied probability of 40.0% and decimal odds of 2.50. A $75 stake at −150 yields a profit of $50.00 and a return of $125.00, an implied probability of 60.0% and decimal odds of 1.67. The favourite pays less per dollar staked, while the underdog implies a lower chance. These figures are for a winning result.
| Price | Stake | Profit | Return | Implied probability | Decimal |
|---|---|---|---|---|---|
| +150 | $100 | $150.00 | $250.00 | 40.0% | 2.50 |
| −150 | $75 | $50.00 | $125.00 | 60.0% | 1.67 |
Worked example: the odd-lot stake
Prices like −110 do not divide neatly, so the stake matters. An $11 stake at −110 gives exactly $10.00 profit and a $21.00 return, with an implied probability of 52.4% and decimal odds of 1.91. A $100 stake at −110 gives a profit of $90.91, and a $200 stake gives $181.82. Profit and return scale in direct proportion to the stake.
Implied probability and breakeven
The breakeven win rate is the share of equal bets that would need to win for profits to cancel losses at that price. For a single price it matches the implied probability exactly, which is why both lines show 40.0% at +150. It says nothing about the true chance of any particular result, and it includes whatever margin the operator has built into the price.
Limits and risk
The calculator handles one straight bet at a time. It does not account for ties, voided stakes, taxes or bonuses. Gambling involves a risk of losing your stake, and whether it is allowed depends on where you are.
