What is a multibet?
A multibet (or multi for short), also known as a 'Parlay' or 'Accumulator', is a bet type that combines a series of single bets (also known as legs within a multi) into one bet. The odds in the bet multiply for every additional leg you add to the multibet. There has to be a minimum of two legs in your bet to be classified as a multibet. The maximum number of legs in a multi is dependent on the bookmaker you are placing the bet with. A multibet requires all legs to win to be successful. That is, if one leg loses, your entire multi loses (that’s why you usually get big odds for adding more legs)! A multibet can combine different bet types across a range of markets as long as they are not conditional (such as Team A to Win the 1st Quarter and Team A to clear the 1st Quarter Line). Some bookmakers, however, now offer 'Same Game Multis', allowing users to combine multiple markets from the same event. The odds for Same Game Multis are calculated differently and are different to the Multi Calculator on this website.
Some bookmakers now also allow bettors to 'cash out' before all legs of their multibet have resulted. For example, if the bettor had a 7 leg cheeky multi and the first 6 legs have already won, they could choose to accept an amount lower than what they stand to win if the final leg wins, but removes the stress and gives a guaranteed payout.
How does the Multi Calculator work?
Our Multi Calculator quickly calculates the total odds for your multibet. You can enter the odds of each leg and the calculator will then tell you how much the overall multi is worth; the total value of the odds.
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)
Total: Over 44.5 (-120), Under 44.5 (+105)
Prop: Kirk Cousins TD Passes: Over 2.5 (+165), Under 2.5 (-190)
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 Payouts
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.
