What is overround?

Betting Calculator Paddy Power

A betting odds calculator and converter multiplies the stake by the odds to determine the potential profit on your sports betting wagers. Simply enter your stakes and odds, and our tools will tell you how much profit you should expect to receive using American, fractional or decimal odds. Betting Odds are written in terms of 100 as an industry standard. The easiest way to think of the plus and minus signs is as follows. If it is a plus, you will receive more than a $100 payout on a $100 bet. If it is a minus, you will have to bet more than $100 to win a $100 payout. Calculate bet returns for Accumulators, Lucky 15's, Doubles, Trebles, Football, Horse Racing and more. The most comprehensive and reliable bet calculator. American Odds are the default odds at American sportsbooks. These odds are based on winning $100 for a given bet. Betting a Favorite: The odds for favorites will have a minus (-) sign, and represent the money you need to risk to win $100. So if you're betting on the Packers at -140 against the Vikings, that means Green Bay is a slight favorite. Given a general quadratic equation of the form ax²+bx+c=0 with x representing an unknown, a, b and c representing constants with a ≠ 0, the quadratic formula is: where the plus-minus symbol '±' indicates that the quadratic equation has two solutions.

Overround, also known as the book percentage, is the combined total of priced probability across all outcomes on a single event. The price of each event in a given market directly correlates to the percentage chance of that event winning. The overround adds all these percentages to give the bettor an idea of the formulation of the market. In a perfect world, these totals would add up to 100%, however in order for bookmakers to make profit on markets, it is not uncommon to see markets in the range of 120% - to 130%, and these are the markets bettors should try and avoid, instead trying to side with markets that closer to 100% and giving less of a margin to the bookmakers. In main markets such as moneyline and spread betting, the overround is typically low compared to prop bets such as to score the first basket because these prop bets have a higher variance so in order for the book to make consistent profit, they make the overround on these markets higher. Furthermore, in parlay bets, overround is compounded making the margins even greater for sportsbooks.

Using this calculator you can enter the prices of the events in a given market and produce the overround percentage of the market, showing you whether your pick and the market in total is offering a value opportunity.

A parlay is a single bet that links together two or more individual wagers for a high payout. A 2 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. For a single bet, 2 to 8 teams or totals can be selected.

In order for the parlay bet to win, every one of the wagers must win or push (tie). 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 5 team parlay and have 4 winners and a tie, your wager pays out as a 4 team parlay. If you place a 2 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 $91).
