Arbitrage Calculator: Free Tool for Sports Betting Success
The arbitrage calculator (also arb calculator or surebet calculator) by Gambling Park is a free online tool that helps you determine the profitability of a specific arb and the required stake amount on opposite outcomes.
Arbitrage betting is when you place bets on opposite outcomes of an event across different bookies and lock in a guaranteed profit. No matter who wins or loses, you win.
How Does the Surebet Calculator Work? Example
Let’s see how the arb calculator works with a real example. Say you have $1000 to bet, and you spot an arb in a tennis game C. Alcaraz — N. Djokovic.
- Bet365 has odds of 1.99 for C. Alcaraz to win
- William Hill has odds of 2.04 for N. Djokovic to win
You go to Gambling-Park.com and open the arbitrage calculator.
Then, you enter the odds in the corresponding boxes — 1.99 in the “Bet 1” box for C. Alcaraz and 2.04 in the “Bet 2” box for N. Djokovic.
You also enter the total amount you want to bet on the arb ($1000).
Then, you click on the “Calculate” button.
The surebet calculator shows you the following info:
OUTCOME | ODDS | STAKE | PROFIT | ROI, % |
C. Alcaraz | 1.99 | $506,2 | ||
N. Djokovic | 2.04 | $493,8 |
Our free arbitrage calculator is a powerful tool that works in real-time and tells you exactly how much to bet on each outcome.
How to Use the Arb Calculator?
It works for both 2-way and 3-way events, so you can use it for any sport (switch between them on the top panel of the calculator).

Using the sports surebet calculator is easy. Just follow these steps:
- Enter the odds for each outcome (either 2 or 3, depending on the sport).
- Enter the total amount of money you want to invest in the arb.
- Hit calculate and see the magic happen.
The calculator will show you:
- The stake for each outcome (how much to bet on each side).
- Return on investment (if the ROI is negative, there is no profit available, and you will have a guaranteed loss).
- The profit amount for each stake (how much money you’ll pocket from each bet).
The sports arbitrage calculator is a must-have tool for any serious sports bettor. It’s especially useful for live betting, where arbs pop up all the time. But there’s one more thing you need to know.
✅ The arb calculator also helps you spot fake arbs that are actually losing bets.
If, after entering the odds, you see a negative profit value, then it’s not an arb. It’s a trap. Avoid it at all costs.
