When it comes to sports betting, the main goal for anyone who wagers a single dollar on any sporting event is to turn that dollar into two or three or four or hundreds of dollars. It's much easier said than done, and that is why the betting industry is one of the hardest industries to break into in a big way.

To calculate “-” odds, divide 100 by the odds, then multiply that quotient by the amount you bet. For example, suppose you want to calculate how much profit a $50 bet on the Dodgers would yield. If you bet on 4/1 (said “four-to-one”) odds, you will get $4 profit for every $1 you bet. You will also get your original stake back. Fractional odds refer only to the profit you’ll make on your bet. Multiply your wager.

How Are Odds Determined? Odds are engineered to attract equal action on both sides of a betting line. In a perfect world, a sportsbook receives equal betting volume on both sides of a wager then, win or lose. Decimals quote the potential return should the bet succeed, relative to the stake. If $10 is bet at odds of 4, the total returned is $40 ($10 x 4) and the potential profit is $30 ($10 x 4 minus the. An event in the real world with two outcomes, like a coin flip, might have 50/50 odds. Those probabilities add up to 100%. But in sports betting, it’s different. Once you convert odds to probabilities and add.

Those that do, however, generally stick to single-game wagers over the course of the NFL/MLB/NHL/NBA seasons, and they enjoy the process of grinding out nightly wins and boosting their bankroll that way. It also helps to understand the risk vs. reward a little better when betting on single games because NFL and NBA offer spread betting , which in turn is almost exclusively listed at -110. The bettor understands this and because of that they can bet according to their bankroll management plan .

For those who don't have the patience to bet one game per night and slowly build up the bankroll, the parlay route is always the go-to way, and more often than not it leads the bettor to bust his bankroll. Don't get me wrong, I too have dreamt about winning a 15-leg parlay on a Sunday afternoon and cashing in five digits, but I am also realistic and know it's unlikely to happen.

If you still want to bet parlays, you must understand what they are and how they work.

What is a Parlay

A parlay is a single bet that links together two or more individual wagers for a high payout. A two-team parlay might pay 13/5, a three-team parlay might pay 6/1, a four-team parlay might pay 10/1, and so forth with the payouts getting higher with more teams or totals selected.

In order for the parlay bet to win, every one of the wagers must win. If any of the selections lose, your wager loses, regardless of the outcome or cancellation of the other games. If one or more selections is a tie, postponed, incomplete, cancelled or rescheduled for another day, then the wager reverts to the next lowest number. For example, if you place a five-team parlay and have four winners and a tie, your wager pays out as a four-team parlay.

If you place a two-team parlay and one team wins and one ties, the wager becomes a straight bet. The resulting wager will have the same risk amount with the win being calculated to reflect the odds of the remaining team (Example: on a two-team $100 parlay with team A +110 and team B -110 ,if A ties and B wins the resulting wager will be a straight play on B risking $100 to win $90).

How to Calculate Payouts Quickly?

For the record, let it be stated that sportsbooks are in the business of making money and as such will do anything in their power to turn as much of a profit as they can. With that said, many sportsbooks offer up fixed parlay odds that aren't anywhere close to what the true odds of a parlay should be.

For example, I came across the payout chart from 5Dimes that show what odds are offered to bettors who play parlays on football and basketball. Keep in mind, these payoff odds are based on all lines being -110.

As you can see, the fixed odds of a three-team parlay seem lower than the true odds of a three-team parlay, which should be 6.96 (1.91 x 1.91 x 1.91). In order to determine how much your parlay would pay out, you would then take that 6.96 odds and multiply it by the amount you wish to wager. In order to see just profit, you would then subtract the wager amount form that total. Example: 6.96 x $300 = $2090.10 - $300 = $1790.10.

How Do Sportsbooks Calculate Odds

As you can see from the chart above, 5Dimes will pay you $1800 for this bet, which is better than true odds. Some sites will pay you at true odds value, a little below, or a little above. It all depends on which sportsbook you use.

If you were to put together a parlay with teams that offer up different odds than -110, you would then do the exact same process. You would first convert the American lines into decimals and multiply them all together.

For example, a parlay that consists of teams with odds of -110, -140, -110 and +210 would turn into a parlay that has odds of 1.91 x 1.71 x 3.10 x 1.91.

How Do You Calculate Odds In Sports Betting

The result of multiplying those odds together would give you odds of 19.338, and then you would multiply that by your wager amount, which in this case would be $300 again.

So, 19.338 x $300 = $5801.55 - $300 (your wager) = $5501.55 of pure profit.

We cannot compare this number to the chart above as the chart is only if all bets are -110. Since the bets are varying here, the odds must be calculated or done using one of the calculators or the betting sites.
