Before we delve into examples on how to calculate bet returns that have been presented in different odds formats, it is important to note that, irrespective of which odds format you use, the potential profit is the same, the presentation just differs.

Odds expression indicating return relative to 100 unit base figure. With money odds, whenever there is a minus (-) you lay that amount to win a hundred dollars, where there is a plus (+) you win that amount for every hundred dollars you bet.

Positive odds - 100 divided by (the american odds plus 100), multiplied by 100 to give a percentage e.g. American odds of 150 = (100 / (150 + 100)). 100 = 40%. 1 day ago  The handicapping and odds information (both sports and entertainment) found on SportsBettingDime.com is strictly for entertainment purposes.

Calculating profits with Decimal odds

Decimal odds are predominantly used in continental Europe, Australia and Canada. The format is a simple numerical representation of the potential return of a bet, which includes the stake amount.

The potential return on a bet quoted in Decimal odds is extremely easy to calculate by simply multiplying the amount you wish to bet by the Decimal odds offered – just remember that the return includes your stake. Here is an example of Decimal odds in a 1X2 soccer market from Pinnacle:

Calculating the potential return for a $100 Bet on Chelsea at 2.270:

Odds x Stake = 2.270 X 100 = 227

As this includes your original $100 stake amount, the potential profit is $127.

Calculating the potential return for a $100 bet on Liverpool at 3.390:

Odds x Stake = 3.390 x 100 = 339

Calculating profits with American odds

American odds are unsurprisingly the default format used in America. They start either with a positive or a negative sign, e.g. -110, or +120. A negative number indicates the amount you must stake to make $100 profit (or the equivalent in your chosen currency) and a positive number indicates how much you might profit if you bet $100 (again, this would be the equivalent in your chosen currency).

Using the example above, if you bet $124 on the Washington Redskins -2.5 handicap with American odds of -124 and they cover the spread, you will make $100 profit (plus your original $124 stake). If you bet $100 on the Dallas Cowboys +2.5 handicap with odds of +112 and they cover the spread, it will return $112 profit (plus the original $100 stake).

As with any odds format, the potential return and profit from a bet is relevant to the stake amount. Using a $100 bet example is the easiest way to calculate profits with American odds, but below is a simple formula to work out potential returns for any stake.

Negative American odds calculation:

(100/Odds) x stake

Positive American odds calculation:

Odds x (stake/100)

If we use the odds from the above example, you could bet $13.75 on the White Sox at -129 and your potential profit is $10.66:

Using the same example for positive odds, you could bet $15 on the Royals at +119 and your potential profit is $17.85:

Odds x (Stake/100) = 119 x (15/100) = 17.85

The sports betting odds calculator allows you to convert betting odds across American and Decimal odds. The odds calculator will also tell you the equivalent implied probability of winning as well as return and profit given a bet amount. Fields with a yellow background are editable.

How to use a sports betting odds calculator

The sports betting calculator above allows you to see various outputs such as decimal odds, implied win probability, amount returned on a bet (or “payout”), and bet profit.

The yellow fields above are input cells. All you need to enter are the American odds of a bet (either by using the slider or entering the value in the field) and the bet amount.

You can use the odds calculator a few different ways:

• Convert odds from American to Decimal
• Convert American odds to an implied win probability percentage
• Return the profit of a given bet if it wins

The betting odds calculator will work for all types of bets: point spread, moneyline, total, or props. For any bet that has a handicap value set (ex: a point spread of -6, total of 43, etc.), you can ignore that part and simply enter the odds associated with that bet.

Moneyline Odds Calculator

Take for example the following matchup and associated moneyline odds to win the game:

Minnesota Vikings (+260) at San Francisco 49ers (-330)

I have bolded the moneyline odds to make it obvious what we are looking for. If you wanted to place a $10 bet on the San Francisco 49ers at -330, you could enter -330 in the odds calculator above.

You would see the following information as a result. Odds of -330:

• Decimal odds = 1.30
• Implied win probability = 76.7%
• $10 bet = $13.03 payout
• $10 bet = $3.03 profit

Point Spread, Total (Over/Under), and Props

Let’s say you wanted to bet a different market on the same game. Using the Vikings/49ers example, we have the following markets:

Point Spread: Vikings +7 (-110) at 49ers -7 (-110)

Odds Sports Betting Calculator

Total: Over 44.5 (-120), Under 44.5 (+105)

Prop: Kirk Cousins TD Passes: Over 2.5 (+165), Under 2.5 (-190)

Sports Betting Payout Calculator

I have highlighted the actual odds you would enter for any of the given markets. Despite each example above representing a different bet, they all have odds that you can enter into the calculator.

Win Probability Calculator

The odds calculator will also tell you the implied probability of winning a given set of odds.

You can also check out our implied win probability to odds calculator if you want to take a win percentage and translate it to American or Decimal odds.

Using the previous example, American odds of -330 represents a 76.7% implied win probability.

Why is this useful?

Knowing the implied odds of a bet is extremely useful if you are doing your own modeling. If you have a model that says the San Francisco 49ers have a 79% chance to win the game, you could compare that to the implied win probability to see how it compares.

While most models are unlikely to be sharper than the market number, it is a useful comparison point to see how your “number” compares to the market. Using odds calculators are a good way to check how your numbers stack up.

How do I calculate betting odds?

Calculating betting odds will depend on which odds format you used to place your bet: American, Decimal, or Fractional odds. Most bettors in the United States will use American odds. Each odds format represents the same thing: the percent chance of winning.
To calculate this percentage, convert odds from American to Decimal. Then take 1/Decimal odds to calculate the implied chance of winning. You can also calculate the bets payout, profit, and more.
