Your Free Betting Odds Calculator

Welcome to FreeBetCalc, the easiest to use bet calculator on the internet. The calculator works on any mobile device and has several features that no other calculator has. We show recommended bets for all accumulator and combination types such as lucky 15, lucky 31, lucky 63, Canadian, Yankee, Heinz and other exotic bet types. These recommendations are generated by an algorithm that looks for value bets. By combining value bets, you ensure that your combinations have the highest chance of generating a profit long term. We list recommended bets that you can add directly into the calculator and experiment. Very quickly you'll be able to see what effect certain losing bets (if you've chosen a full-cover bet type) will have on your bottom line.

For sure bet lovers and arbitrage fans, FreeBetCalc exclusively offers a “matched betting” bet type option. These bets allow you to take advantage of bookmaker freebet bonus offers. Just select the “Matched Betting” bet type and select a bet to add to the calculator from the list that is generated. We show you exactly how muck to back and lay. If you’d like to know how best to use these free bets to increase your bankroll with minimal risk, then please read our ultimate guide to matched betting.

Whether it's for pure artbitrage (arbing) or just to break even in order to claim a bonus, the art of how to bet at Betfred (or William Hill or any of the bookies) and lay on Betfair (or Smarkets or any of the betting exchanges) is a complex one. Of course we're biased but we feel the best guide on the market is our very own. You can get it on right now, and it even comes free with 6 months free members' access to this very site. It's UK-focuses, but will work in Australia too.
