How to use an arbitrage calculator

While there is no guaranteed way of winning sports bets, certain strategies or tools have been proven to be quite helpful. One such tool I often recommend is the arb calculator. Using an arbitrage betting calculator can help you determine how much to stake on 2-way and 3-way bets to make a profit.

An arbitrage calculator operates in a simple manner that compares odds for different outcomes at different sportsbooks to generate an overall potential return for a wager. This allows bettors to place multiple wagers on the same event to guarantee a return, no matter the result.

I understand how confusing arbitrage betting can be, especially if you are making the calculations manually. There are several values to consider when adding up the best odds for individual outcomes and the right amount to stake. Nevertheless, this issue can be resolved by effectively using an arb betting calculator.

An arbitrage calculator simplifies the complex calculations needed to identify profitable bets, ensuring that bettors know the exact amount to stake on each outcome to maximize returns.

The products of this calculator include the bet amounts for each outcome, total stake (sum of all individual bets), individual payout, total payout, and profit margin.

How to use an arbitrage calculator for sports bets - a quick step-by-step guide

  1. Select two different bookies to find the best odds: The first step is selecting two bookmakers that offer odds for the same events, which hold opposing outcomes.
  2. Supply these odds to the arbitrage calculator: Enter into the calculator the odds on the bets.
  3. Provide the stake amount: Bettors can now enter the amount they want to stake on their original wager; this will reveal an expected payout. Now, this is where it gets interesting as the calculator will also display the amounts you would have to stake on a bet on the opposing outcome in order for you to make a return, no matter the result of the event.
  4. Place the bets: Once done with the previous steps, bettors can now place stakes in both sportsbooks accordingly, awaiting the end of the event to receive payouts.

An example on how to use the arbitrage betting calculator

Let’s assume I am betting on a soccer match between Real Madrid and Man City using an arbitrage calculator. The odds on two different sportsbooks are as follows:

  • Platform A: Odds  2.10 (Real Madrid wins)
  • Platform B: Odds 2.05 (Man City wins)

With a total stake of $100, a 2-way arbitrage calculator should provide the outcomes highlighted below:

Platform AOddsStakeReturn
Real Madrid2.10$48.78$102.44
Platform B
Man City2.05$51.22$105.00
Total Stake
$100
Min Profit
$2.44

Irrespective of which team wins, I will get a total payout of more than $100, with a minimum profit of $2.44 guaranteed.

Arbitrage Calculator odds explained

Also known as arbs betting, miracle bets, surebets, and sure wins, an arbitrage bet allows you to stake on different events, with guaranteed returns irrespective of the outcome of each one. This type of bet runs on the advantage of disparities between sportsbooks.

With this calculator, you can wager two or more outcomes for a single sports event on separate platforms, and your profit is covered by the right odds. Thus, a simple calculation is necessary to determine if bettors have an arbitrage opportunity. Doing this manually can be hectic and error-prone; hence, the need for this tool.

Arbs betting allows people to wager on outcomes with guaranteed profits; it involves placing bets on various events across different bookmakers using simple calculations to land arbitrage opportunities.

An online arbitrage calculator splits your stake amount between bets according to the odds provided. Then, it goes further to reveal an expected payout that helps you to determine whether the bet is worthwhile.

Arbitrage bets vs hedge bets

While both hedging and arbitrage seem similar and used for staking on possible outcomes of an event, they are different. The main difference lies in the ways they are used: a hedge bet refers to the second bet wagered on a different outcome. The first bet must have already been placed and locked in in order for you to use this strategy. So, if I make an initial bet and do not feel confident of the result, I’ll place another one on a different outcome. This is known as a hedge.

Hedging betting is about minimizing risks, ensuring returns irrespective of the team that wins. For arbitrage bets, wagers get placed simultaneously, and it requires more consideration as arbitrage betting takes advantage of discrepancies in odds being offered by different sportsbooks. Nevertheless, you can determine the suitability of an event using an arbitrage calculator.

Why is an arbitrage calculator useful?

Should bettors use this calculator at all? Intuitively choosing the right bankroll percentage for an arbitrage bet appears impossible. That said, here are some top reasons I prefer a 2-way or 3-way arbitrage calculator for these mathematical calculations:

It gets complex calculations done in no time

The basic use of a calculator is easing the burden of sorting out complex numbers in calculations. So, an arbitrage calculator offers sports bettors an edge, automating the process of determining the bet amounts to be staked on each outcome. I find this to be quite helpful since it cuts down the time needed for the manual calculation of probabilities and payouts, and it reduces human error.

Allows easy adjustments

Rather than manually working out odds and outcomes separately in a bid to find the perfect arbitrage bet, a calculator allows one to make quick adjustments. With this tool, I can easily tweak the wager amounts and odds, as it enables one to determine the optimal weights for each wager while reducing losses.

Maximizes betting efficiency

Since a free sports betting arbitrage calculator allows quick adjustments, bettors can easily work out varying potential returns. It also provides more opportunities across a wide range of events in various sports.

Improves potential returns

Rather than sticking to conventional strategies, using an arbitrage betting calculator offers the chance to improve potential returns.. With this calculator, it is easier to decipher the exact bet sizes you need to cover possible outcomes, thus increasing your odds of turning a profit despite the event’s result.

What other betting calculators are available?

Aside from an arbitrage calculator, there are many other calculators available to handle various aspects of sports betting. These betting calculators include:

Betting CalculatorsFunction
Hedge Bet CalculatorDerives the ideal amount to place on a hedging bet.
Dutching CalculatorCalculates the amount to stake on each bet selection for equal profits.
ROI CalculatorDetermine a bet's expected profit or loss margin
Matched Bet CalculatorCalculates profits from free bets using lay and back bets.

Conclusion–using an arbitrage calculator can offer valuable insights

Since bookmakers are known to set different odds for similar events, comparing these odds presents an excellent opportunity for bettors to gain valuable insights into which wagers to place. With an arb calculator, bettors can easily determine the right amount to wager on opposing outcomes on an event by comparing odds from two or more sportsbooks and taking advantage of discrepancies between these odds. An arbitrage betting calculator will display the best amount to stake on each outcome in order to make a profit as well as expected payouts. When used correctly, you can take advantage of this information by playing more informed wagers, thus improving your own betting strategy. Although there are never any guaranteed wins in sports betting, using an arb calculator can take a lot of the guesswork out of the equation by simplifying otherwise complex calculations. This, in turn, can help you adjust your personal bankroll and optimize your time spent betting on sports events.
