Free Arbitrage Calculator for Sports Betting
Arbitrage betting is one of the rare times in sports betting where you aren’t picking a side. Nope, you’re backing numbers. How so? When you bet on both teams using odds from different sportsbooks, you can secure a return no matter who wins, but only if the odds line up the right way.
Here’s how it works: If one sportsbook has the Knicks at +180 and another has the Pacers at -130. If you split your stake across both teams in the correct way, you’re not just crossing your fingers and toes; you’re nailing down a guaranteed payout.
Because it can be lucrative, we built you an Arbitrage Betting Calculator! You don’t need to make a spreadsheet. Or do math on the back of a napkin. All you do is input the odds, enter your total stake, and it’ll tell you exactly how much to put on each side, and if it’s an opportunity worth snagging!
If you want to find the lower-risk profit opportunities when the numbers line up? That’s what our Arbitrage Calculator was made for! It makes the math less math-y.

How to Use the Arbitrage Betting Calculator
It only takes a few clicks to see if the odds are working in your favor! Below is a 5 step-by-step guide on how to use our arbitrage betting:
Step 1: Pick your odds format
The first step is to choose how you want the odds to appear, and you can pick from American, Decimal, or Fractional. You can also mix formats across outcomes if need be.
Step 2: Enter the odds for each outcome
Pop in the odds for two or three possible results, depending on the type of market you’re looking at, like two-way for basketball or three-way for soccer.
Step 3: Type in your total stake
This is the total amount that you want to bet across all outcomes, not per side. Our calculator will split it up for you!
Step 4: Set your minimum ROI
Tell the calculator the lowest return that you’re willing to take. If the numbers don’t meet that threshold? It’ll let you know.
Step 5: Click ‘Calculate’
You’ll instantly know if there’s a good opportunity, and, if so, how much you should put on each side to get a guaranteed return.

Tips for Successful Arbitrage Betting
The calculator does the grunt work, but how you use it matters, too! Look below for tips that’ll help you get the most consistent results:
- Use more than one sportsbook: The entire strategy relies on comparing lines. The more sportsbooks you have access to? The better your chances are of seeing a profitable gap.
- Move fast: Odds never sit still. As soon as one side starts pulling action, the value can disappear. If the calculator shows an opportunity, don’t wait too long to act!
- Watch for limits: Some sportsbooks restrict max bets or flag accounts that only bet on certain markets. Know the rules and restrictions before you bet.
- Account for fees: Payout fees, deposit charges, and currency conversions can cut into your return. If you’re after a small margin, this will matter more than you think!
FAQs about Arbitrage Betting
If you’re brand new to arbitrage betting, the following are the most common questions we hear from our readers!
Is Arbitrage Betting Legal?
Yup, it’s totally legal as long as you live in a place where gambling is legal. You’re just betting on price differences between sportsbooks. That being said, there are some platforms that might limit or flag your account if they notice that you’re doing it.
Can I Lose Money Doing Arbitrage?

What Sportsbooks Are Best for Arbitrage Betting?
Look for the sportsbooks that post odds early, don’t adjust the lines too aggressively, and offer quick withdrawals. And using a combo of major and smaller sportsbooks will help you find the most gaps.
What’s the Difference between 2-Way and 3-Way Arbitrage?
2-way arbitrage involves two possible outcomes, like one team or the other winning. And 3-way includes a third result, like a draw, which happens in soccer or in some prop markets.
