Browser Extension vs. Website Calculators

While the sports betting calculators on the website are fully functional, there are a few extra features and tools that are available in the Browser Extension but not on the website.

  • Sportsbook Organizer: Whether you use two sportsbooks or 20, keeping track of their key info is easy with the Sportsbook Organizer.

  • Transaction Logger: Securely record the deposits and withdrawals for all your sportsbooks in the same place to get a complete view of your overall bankroll.

  • Quick & Convenient: Access your calculators and trackers at the top of any browser window.

  • Dedicated Windows: Each calculator and tracker opens in its own smaller window to make it easier to move them around your screens. You can also combine them into one window if you prefer, just like a normal browser window.

  • Easy Screenshots: Screenshot your calculators, organizer and logger with the click of a button and easily save or share the image.

  • Calculator/Tracker Integration: Copy your total bankroll into the Sportsbook Deposit Calculator with one click, if you use the Sportsbook Organizer.

  • Customizable Colors: Your calculators and trackers can be any colors you'd like. Choose the colors of your favorite team or simply the colors that are easiest for you to see.

SPORTSBOOK TRACKERS

Keep and grow your funds by knowing where they are and how they got there

Organize your sportsbooks and maintain a full view of your overall sports betting bankroll using the sportsbook trackers in the Eye On The Bet browser extension.

What's included in these trackers?

Two sportsbook trackers work both separately and together to give you a complete view of your sportsbooks and sports betting funds. Read about them below.

Sportsbook Organizer

Whether you use two sportsbooks or 20, keeping track of their key info is easy with the Sportsbook Organizer.

Simply add the sportsbooks you use to the organizer to track the following important data:

  • Cash Balance

  • Unplayed Free Play

  • Remaining Rollover

  • Sportsbook Classification (customizable)

  • Sportsbook-specific Notes

  • Net Profit/Loss (derived from the Deposit/Withdrawal Tracker)

Transaction Logger

Record the transactions for all your sportsbooks in the same place to get a complete view of your overall bankroll.

Log your Sportsbook Deposits and Withdrawals to track the following:

  • Deposit & Withdrawal amounts

  • Bonus tied to a specific deposit

  • Transactions Status (Completed, Cancelled, Edit)

  • Profit/Loss is tallied for each sportsbook, then shown separately on the Sportsbook Tracker

Why not include the sportsbook trackers on this website?

In order to preserve the data from one session to the next that a user inputs into these trackers, without the risk of that data being lost if the user clears their browser data, we would have to store the data on our server. Eye On The Bet is simply not in the business of collecting user data.

Data Privacy & Security: The browser extension is able to store that data securely in a user's browser, in a special storage area designated solely for this browser extension. This means your data never leaves your computer and is protected from clearing browser data.

How do I use a sports betting calculator?

Using a sports betting calculator, depending on the type, may involve inputting information about your bankroll size, the odds and stake for one or more wagers, and/or the details of a bonus offer from a sportsbook.

For example, using a basic sports betting calculator typically involves:

  • Entering Odds: Input the odds for one or more wagers, provided by the sportsbook(s).

  • Inputting Stake: Enter the amount(s) you plan to wager.
