OK, so you now have a way of converting any type of odds using our gambling calculator.
But what if you want to work out your own odds on a market and whether a bet is value?
With our sports betting calculator below, you can choose from the drop-down box the chance of an outcome happening. The betting odds calculator will then work out what the Fractional, Decimal, and Moneyline odds SHOULD be.
If, from your research, you've worked out that Brazil are a 60 percent chance to win their World Cup semi-final, choose it from the drop-down menu and you will see that Fractional odds are 2/3 on, the Decimal odds 1.67, and the Moneyline -150. Does that match the online bookies' pricing?

Moneyline / American Odds
When betting on the moneyline in American odds, the team that you are betting on just needs to win the game. If Team A is -200 and Team B is -150 on Moneyline, you'd need to place a $/€/£200 bet on Team A in order to win $/€/£100 if they win. It also means you only need to place $/€/£100 on Team B in order to win $/€/£150.
Fractional / UK Odds
The fractional odds displayed shows how much you can win on a bet compared to how much you put on it. The first number will show how much you can win, when you place the second amount as a wager. If you place $/€/£10 on a 2/1 bet, you'll receive $/€/£20 in winnings (not including your original bet amount).
Decimal / European Odds
With decimal odds, you will multiply your wager by the decimal shown, with the answer being what you will receive in winnings, including your original wager. Betting $/€/£10 on a 5.00 bet will net you $/€/£50 in winnings (including your returned bet).

Odds Calculator FAQ
How do you calculate odds ratios?
Learning how to calculate odds isn’t as difficult as it may seem, so if you are having trouble, here is a quick explanation. Taking a 2/1 wager as an example, you can calculate the percentage chance of this ratio bet by adding the right-hand figure to that of the left, so in this case it would be one plus two equalling three. From there, you divide the right-hand side – one – by the total figure – three – giving the answer of 33.3% or 0.333, which represents odds against, so with simple subtraction you can figure out that the odds for are 66.6% or 0.666.
What is the benefit of using a betting calculator?
When looking to make a bet, speed is key, something that our sports betting calculator can help with. Literally taking the equation out of the equation, our sports betting calculator provides a super quick way for you to work out how much you’ll make based on the wager you lay down and the odds presented. Input your type of odds, given odds, and total bet, and the betting calculator will handle the rest.
Is a moneyline calculated differently?
Moneyline odds (sometimes listed as US or American odds) probably rank as the most confusing odds format out there, largely as it appears to be used exclusively in North America. Based on a “+” and “-” setup within a market, here’s how you can go about calculating odds of this type – outside of using our moneyline calculator obviously. Taking a £100 wager at -110 as an example, let’s look at how such a bet breaks down. Within the -110, the -100 is required to generate a positive payout, so it’s a case of payout equals bet amount (-100 plus moneyline odds/100). Yes, it is a bit complicated to understand, but that is the nature of the beast when it comes to moneyline odds.
What are the different types of odds?
You certainly aren’t going to be handcuffed when it comes to odds types, as they can be displayed in a number of different ways. Moneyline odds are the popular format stateside, with it based upon “-“ and “+” symbols. For example, if Team A is -200 and Team B is -150 on a moneyline bet, you would need to place a £200 bet on Team A in order to win £100 if they win. It also means you only need to place £100 on Team B in order to win £150.
Those based in the UK will be familiar with fractional odds, looking at 2/1 as an example again; the initial number will display how much you can walk away with, while the second number is the ratio to the wager. For example, by placing £100 on a 2/1 bet, you will receive £200 in winnings – with this figure not including your original wager amount.
Finally, on European shores, decimal odds are often the preferred choice. When working with decimal odds, you will multiply your wager by the decimal shown, as such betting £100 on a 5.00 wager will secure you a £500 win – with this including your returned bet.
What is expected value?
Expected value is the total amount that a punter can expect to win (or possibly lose) when they place a wager on the same odds multiple times over. Expected value is calculated by multiplying your winning probability with the amount you could win per wager, then subtracting the losing probability multiplied by the amount lost per bet. While it’s hardly a science - when used consistently - expected value should give any punter a clearer grasp on the value for money that a bookmaker is providing.
