  • Price Boost

    How Does The Effective Odds Calculator Work?

    If a bookmaker is offering a price boost where some or all of the odds are paid as a free bet, you will need to enter the figures into the effective odds calculator above to work out the effective back odds.

    When price boost winnings are paid as a free bet, you will not receive your stake back on the free bet portion when you place the free bet, so this will affect how much you need to lay for matched betting purposes. The first thing you need to do is calculate the effective odds using this calculator.

  • Paid As Free Bet

    How Much of the Boost Is Paid as a Free Bet?

    Firstly you need to let us know how much of the profit boost is paid as a free bet. You can choose between “All winnings paid as a free bet” meaning that all the returns from the profit boost are paid as an SNR free bet. The second option is “Enhanced winnings paid a free bet”. This means that the returns from the standard odds will be paid as cash, but the boosted portion will be paid as a free bet. This is the most common promotion that is used for price boosts that use follow this promotion.

    Let’s look at an example: Let’s say a bookmaker runs a promotion offering Liverpool to beat Man Utd, was evens, boosted to 2-1 (3.0) with boosted winnings paid as a free bet. If you backed at £10, you would receive £10 winnings (plus your stake) and £10 as a free bet. It is the boosted portion only that is paid as a free bet.

    Enter Enhanced Back Odds

    Here you enter the boosted price. In the example above you would enter 3.0 as this is the boosted price.

    Enter Current Back Odds

    If you have selected “Enhanced winnings paid as a free bet” as the option you will need to enter the current back odds from the bookmaker website you are betting with. In the example above this would be 2.0 (evens).

    Free Bet Profit (%)

    In this section of the calculator you need to enter the % return you expect from the free bet if you were matched betting. A good return from a free bet is around 80% at higher odds. But if it’s with a bookmaker that typically offers poorer odds, opt for something between 60%- 80%.

    Convert

    Press convert and your effective odds will be displayed. You can then use this figure in our matched betting calculator to work out the value of the offer.

I like to have a bet at the weekends. Yesbets is a great resource for helping me find all the latest offers from bookmakers. They’ve helped me grab plenty of free bets over the years. Jin
Yesbets really helps me get the most from my betting. Their guides on Cheltenham and Ascot ensure I never miss an offer from the bookies. I grabbed over £400 for Cheltenham and helped me come out a winner. James
It’s great to have a site that compiles all the best offers in one place. Not just the signup stuff from bookmakers, but promotions for accounts I already have. Yesbets is my first port of call before I have a bet. Chris
Yesbets takes the hard work out of finding free bets. Not only does it show the best free bets from the big boys you’d expect, but also the bets from the scores of smaller bookies that want a piece of the pie. Need all the free bets you can stomach? You’re in the right place at Yesbets. Tibbs
