Prophet Guides

Using the Matched Betting Calculator is easy and efficient. Here's a step-by-step guide to help you get started:


  • Find Your Sportsbook Bet (NOT on Prophet).
    Begin by identifying the bet you want to make on your sportsbook. It could be a boosted price they're offering or any other bet you wish to place. Take note of the odds and the size of your bet – this is your "Sportsbook Bet."


  • Access Prophet Exchange and Determine the Exchange Bet Odds
    Next, head over to Prophet Exchange and find the odds for the opposite result to the one you bet on with the sportsbook. If you're using one of our "Prophet Boosts," this would typically be the "No" market. For a standard game, it's merely the odds of the opposing team or outcome you didn't bet on initially. For instance, if the game is Lakers vs. Celtics, and you bet on the Lakers to win with the sportsbook, your "Exchange Bet Odds" would be the odds of the Celtics winning.


  • Account for the Commission
    Commission is a percentage of your winnings that the exchange takes only if you win. At Prophet Exchange, the commission is a mere 2%, and we often have promotions that reduce this number to zero.


  • Input Values into the Calculator
    Once you have the odds and sizes of both your sportsbook bet and the exchange bet, as well as the commission percentage, enter these values into the Matched Betting Calculator.


  • Obtain the Exchange Stake and Resulting Profit
    After entering the required data, the calculator will generate two vital figures;


    • Exchange Stake: This tells you exactly how much you should bet on Prophet Exchange to guarantee maximum profit regardless of the game's outcome.
    • Resulting Profit: This figure will show you the exact amount of profit you can expect to make based on your calculated exchange stake.

That's all there is to it! The Matched Betting Calculator takes care of all the math, ensuring a straightforward and user-friendly experience. With the calculations at your disposal, you've just embarked on your matched betting journey, setting the stage for smart and risk-free betting. Enjoy the benefits of matched betting and maximize your earnings!

Using our Free Bet Calculator allows you to find the most profitable way to capitalize on any free bet offers given to you by a traditional sportsbook.


  • Start by identifying the free bet you want to make on your sportsbook. Take note of the odds and the size of your bet – this is your "Sportsbook Bet".
  • Next, head over to Prophet Exchange and find the odds for the opposite result to the one you bet on with the sportsbook. Input those odds into the "Exchange Bet Odds" section and the corresponding Exchange Commission.

The calculations will display your resulting profits!

Using our Risk-Free Calculator allows you to find the most profitable way to capitalize on any risk-free offers given to you by a traditional sportsbook.


  • Start by identifying the free bet you want to make on your sportsbook. Take note of the odds and the size of your bet – this is your "Sportsbook Bet".
  • Next, head over to Prophet Exchange and find the odds for the opposite result to the one you bet on with the sportsbook. Input those odds into the "Exchange Bet Odds" section, with the corresponding Exchange Commission.
  • The extra thing you need here is your “Expected Retention” - this is something you decide based on your experience based on how much cash you tend to convert your free bets into. Generally, this is around 80%, but if you search, you can find better conversions.
  • If your risk-free bet loses, you’ll be left with a regular free bet, which you can use our free-bet calculator to maximize your profits on.

The calculations will display the optimum amount to place on the exchange, accounting for all the different scenarios of either your first bet or risk-free bet winning or losing!

Have you ever wondered about the significant savings you attain by opting for a betting exchange or a traditional sportsbook? The Prophet Exchange Savings Calculator is a user-friendly tool that provides this precise insight in just two easy steps.
