About this app

Betting Arbitrage Calculator helps betting arbitrageurs compare odds across multiple outcomes and understand the numbers behind a potential opportunity.

Enter odds for two to fifty outcomes and calculate the combined implied probability, projected payout, estimated profit, return on investment, and balanced stake allocation. Choose whether to distribute a total stake across every outcome or calculate returns from independently entered stakes.

Features include:
• Calculate arbitrage opportunities with 2–50 outcomes
• Enter decimal, American, or fractional odds
• Balance stakes across the selected outcomes
• Include sportsbook commissions and fixed fees
• Review estimated payout, profit, and return on investment
• Convert between supported odds formats
• View implied probability while converting odds
• Evaluate potential middle bets with a dedicated calculator
• Save completed calculations locally for later reference
• Choose light, dark, or system appearance

Betting Arbitrage Calculator is an informational calculation tool. It does not find live odds, connect to sportsbooks, place wagers, or accept bets. Always verify the entered odds, commissions, fees, stake limits, and calculated results before making a financial decision. No outcome or profit is guaranteed.

The app is free to download and supported by advertising. Optional in-app purchases can remove ads or unlock additional features. Pricing is displayed in Google Play and may vary by region.
