How to Use the Odds Payout Calculator

Whether you are betting on sports, playing at a casino, or analyzing financial risks, our odds payout calculator simplifies the process of determining your potential return. By entering your stake and the specific odds offered by a bookmaker, you can instantly see how much you stand to win and the total amount that will be returned to you if your wager is successful.

To get started, simply follow these steps:

1. Select Odds Format
Choose between American (+/-), Decimal (e.g., 2.50), or Fractional (e.g., 5/2) formats depending on what your sportsbook uses.
2. Enter Bet Amount
This is the total amount of money you are wagering (your "stake").
3. Enter Odds Value
Input the numerical odds value. For American odds, ensure you include the plus (+) or minus (-) sign.

How It Works: The Formulas

The odds payout calculator uses different mathematical formulas depending on the odds format selected. Understanding these formulas helps you realize the "implied probability" of an event occurring.

American Odds

American odds are centered around the number 100. Positive odds (+) indicate how much profit you make on a $100 bet. Negative odds (-) indicate how much you must bet to make a $100 profit.

Positive (+) Profit = Stake × (Odds / 100)
Negative (-) Profit = Stake / (|Odds| / 100)

Decimal Odds

Popular in Europe and Australia, decimal odds represent the total payout (stake + profit) for every $1 wagered.

Total Payout = Stake × Decimal Odds

Fractional Odds

Common in the UK and horse racing, fractional odds (A/B) show the profit (A) relative to the stake (B).

Profit = Stake × (Numerator / Denominator)

Calculation Example

Example: You want to bet $50 on a team with American odds of +120.

Step-by-step solution:

  1. Stake (Bet Amount) = $50
  2. Odds = +120 (Positive American)
  3. Calculate Profit: $50 × (120 / 100) = $50 × 1.2 = $60
  4. Calculate Total Payout: $50 (Stake) + $60 (Profit) = $110
  5. Implied Probability: 100 / (120 + 100) = 45.45%

Common Questions

What is implied probability?

Implied probability is the likelihood of an outcome as suggested by the odds. If the implied probability is lower than your own estimation of the chance of winning, the bet may represent "value." This odds payout calculator automatically converts any odds type into its implied percentage.

Why do some odds have a minus sign?

A minus sign (e.g., -150) indicates the "favorite." It means you have to bet more money to win a smaller amount of profit. A plus sign (e.g., +200) indicates the "underdog," where the potential profit is greater than the amount wagered.

Can I use this for parlay bets?

While this tool calculates single-bet payouts, you can calculate the final payout of a parlay by converting all individual legs to decimal odds, multiplying them together, and then using that final decimal odds value in this calculator.
