How to use an arbitrage betting calculator
Before incorporating our arbitrage betting calculator into your research, you must understand how it functions. First, you need to be armed with various inputs. That includes gathering the odds (usually moneyline) for each possible outcome on the same sporting event/match. However, it doesn’t have to be tedious; you don’t necessarily need to locate the odds manually.
At TheGruelingTruth.com, we have handy tools that can help you find quality odds across the best US betting sites. While at it, opt for platforms with the best
sportsbook promotions—you’ll need them to minimize your betting expenditure. Among the promotions worth noting are free bets and boosted odds to get the most out of arbitrage betting.
Next, you need to settle on the total amount you intend to wager on the possible outcomes. After you finalize making the above findings, open our Arbitrage sports betting calculator and follow these simple steps:
- Find (select) a game and bet type
– For example, you can opt for the NFL game between the Kansas City Chiefs and Cincinnati Bengals. Then, moneyline market/bet type.
- Identify the odds prices for both outcomes on two sportsbooks
– With the game settled on. Next is getting the best odds at two different sportsbooks. Get the odds for one team to win at Site A and the other at Site B (for the win).
- Key in the prices for each outcome in the empty fields –
Having found the odds for both outcomes, you only need to feed these into the empty boxes provided on our calculator.
- Enter the total wager you wish to bet –
Indicate the combined (total) amount of money you are willing to wager on the events.
- Hit the calculate button –
Initiate the computation process to get the findings based on the calculator’s results.
Our arbs calculator will run the numbers and tell you if an opportunity for arbitrage betting exists. Any positive value shows an arbitrage opportunity, while a negative (-) value shows a bad arbitrage opportunity.
Example
To better reinforce the idea of how our calculator works, consider a high-stakes NBA game between the Cleveland Cavaliers vs Milwaukee Bucks. First, find the moneyline odds on two of the
best US sportsbooks, for example:
- Cavaliers:
+150 at site A
- Bucks:
-125 at site B
With the odds at hand, feed these into our calculator. After that, check/tick your bias (the team you believe will win) and then type in the wager you’re working with, for instance, $100. With this information on our Arb calculator, here is what you will come up with:
| Odds | Stake | Payout |
| Bet 1 (Cavaliers): | 150 | $41.86 | $104.65 |
| Bet 2 (Bucks): | -125 | $58.14 | $104.65 |
| Total stake: | $100 | | |
| Total payout: | $104.65 | | |
| Total profit: | $4.65 | | |
| ROI: | 4.65% | | |
As shown above, our Return on Investment (ROI), in this case, is 4.65%, which is on the positive! Meaning, you’re guaranteed a return/profit regardless of the outcome. However, if it were to equate to a negative, it would mean that this is not a favorable bet and will ultimately result in a loss.
Another note is that the bet amounts differ for the two bets. This is a key factor for achieving a positive return—and that’s where our calculator comes in. You can use the tool to calculate the ideal bet amount for each wager in order to get a guaranteed profit.

Arbitrage betting explained
Arbitrage betting is a go-to strategy among expert gamblers that entails leveraging odds discrepancies on different sportsbooks (for the same game) to guarantee returns regardless of the results. As shown in this reading, the best/simplest example would be betting on both teams for the win—at two betting sites with the best odds on the sporting event.
Still, one may ask, what’s the difference between arbitrage betting and hedging?
Key difference: arbitrage vs. hedge betting
Admittedly, getting confused about the two betting strategies is not far-fetched. But we have just the one-liner to set the record straight! While we have clarified what you get with arbs betting, hedging, on the other hand, applies to an existing bet. In practice, it reduces a bet’s potential risk or loss, by placing a second bet against the original wager.
A good example of hedging a bet would be, say, in a game between the Chicago Bears and Dallas Cowboys, with the Bears as the favorites at odds of -120. With this as your original bet (on a $100 wager) and you get cold feet as the match progresses, you can choose to hedge your bet to minimize the risk or potential losses. To hedge your bet, you would, in this instance, bet on the Cowboys to win at the odds of +110.
For your hedging to work, you would need to place a bet of $47.62 on the Cowboys at odds of +110. This would churn out a total payout of $100, and our hedge profit would be $0, thereby effectively mitigating our losses. However, in the same scenario, should the Bears win, we’ll get a potential profit of $83.33, and our hedge profit will stand at ($83.33-$47.62=$35.71) $35.71.
