Arbitrage Calculator
Hedge bet calculators are critical in sports betting, as they show you how to reduce risk and lock in guaranteed profits.
Arbitrage betting, or hedging a bet, is a less risky approach to betting. It involves placing proportional bets on every possible outcome of an event (with different bookmakers) so regardless of what happens, you will find success.
A sports betting arbitrage calculator, or hedge bet calculator, shows you how to hedge a bet and lock in a return. Arbitrage exists because bookmakers set their odds independently; in other words, the odds on FanDuel are not the same as the odds on DraftKings. When these odds get "out of sync," arbitrage can exist, which allows you to hedge your bets.
How to Use This Arbitrage Calculator
Using an arbitrage calculator is very straightforward:
- Enter Odds (Side 1): Input the decimal odds from the first sportsbook
- Enter Odds (Side 2): Input the decimal odds from the second sportsbook
- Enter Your Stake: Input how much you want to wager on Side 1
- See Results: The calculator automatically shows your required Side 2 stake, total payout, and guaranteed profit
It doesn't matter whether you are betting €50 or €500, this arbitrage calculator will show you exactly how much money you will earn with each arbitrage opportunity.
Example Arbitrage Calculation
Say you have odds of 2.20 for Team A to win on Bet365, and 2.20 for Team B to win on Pinnacle.
Calculation:
- Bet €100 on Team A at 2.20 odds = €220 total payout
- Bet €100 on Team B at 2.20 odds = €220 total payout
- Total stake = €100 + €100 = €200
- Total payout = €220 (guaranteed)
- Profit = €220 - €200 = €20
- ROI = 10%
Regardless of which team wins, you profit €20. That's arbitrage.
