Calculator Glossary

Bet Type

Choose your bet type - From a ‘Single’ to a ‘247’ bet Goliath.

Stake -Enter your stake, this is the amount you bet. If you enter £1 for a ‘single’ this will show as £1, if you enter £1 on a Lucky 15, your stake will be £15, as the stake is multiplied by the number of bets for each bet type.

Win / Each Way

Choose whether you made the bet to ‘win’ or ‘each way’ for a place. If your bet is an each way bet additional options will appear on thebetcalculator. We have defaulted to standard settings for these options but you can edit if needed.

  • ‘Win to win, place to place’ and ‘Equally divided’. In accumulator bets, usually the win return gets added to the subsequent win return, and the each way return gets added to the subsequent each way return. The returns are then combined to calculate your winnings. If you have specified ‘Equally divided’ The returns from each event are split 50/50, half to the win, and half to the each way and then subsequently combined to calculate your winnings.
  • Place odds vary according to the number of ‘runners’ within an event. In horse racing this is defined as:
    • 4 runners or less – winner only
    • 5 to 7 runners – 1st & 2nd, 1/4 odds
    • 8 or more runners – 1st, 2nd & 3rd, 1/5 odds
    • Handicap: 12 to 15 runners – 1st, 2nd & 3rd, 1/4 odds
    • Handicap: 16 or more runners – 1st, 2nd, 3rd & 4th, 1/4 odds
    The bet calculator defaults to ⅕ this is easily editable to calculate returns precisely.
Rule 4

Rule 4 default is off, Rule 4 only applies if you have a non-runner. In this instance the bookie may reduce the odds by a certain percentage. You can turn rule 4 on and apply this % figure to each race only if required.

Decimals / Fractions / Amercian

Odds formats vary across different countries. In the UK odds formats are usually represented as a fraction, ie 5/1, in the US this would normally be presented as a percentage figure ie 500, and in many other countries this would be represented as a decimal figure ie 5.0.


How much have you won or would you win? The results we show are Total Return and Total Profit. Total Return includes the stake that is returned to you and profit is how much money you actually generated from your bet.

Offers Information

Free Bets

Are usually supplementary credits to your account that enable you to increase your stake and hopefully your returns without contributing the full stake yourself. Free bet offers do vary from bookmaker to bookmaker. Free bets are subject to individual terms and conditions. We at The Bet Calculator, do summarise the terms and conditions for each individual bookmaker that we list, however, you can read the full terms and conditions on each bookmakers website that we link to. The majority of offers require the customer to register and make a deposit of funds which is often matched, up to a varying max level. You may also find that you are required to place a bet with minimum odds in order for you to qualify for the bet offer. There are many variations, from the more simple bet £10 get £10 free bet through to Bet 2 x amounts of £15 and a combined £30 in free bets. The free bet offers do normally apply to all available sports betting for the bookmaker you register with, however, you should check this properly in the terms and conditions if you are looking to make a specific bet on a specific sport.

Can I use my free bet at any time?

Free bet offers are usually targeted towards new customers for bookmakers and so if you want to take advantage of a free bet offer, you should do this on a new account or with a bookmaker you have not used before. Free bet offers do change over time at The Bet Calculator, we provide an up to date list of new bet offers, however, the offers do change over time and sometimes they do require the use of a promo code with the free bet so you should use your bet shortly after registering. Once you have made the bet, it may require that you re-invest the stake before you are allowed to redeem your bets.

As mentioned previously, terms and conditions do vary, so if you have any concerns please do read the free bet terms and conditions.

Can I get free bets without depositing funds?

Free bets with no deposit by customers are rare, however, they do come up from time to time, usually for a limited period. We list these offers under our ‘Free bets - no deposit’ tab, so if you are looking for these offers you will find them there. Sometimes there are limitations regarding these free bet offers and sometimes bookmakers will require you to re-bet the stake before they will allow a payout against these bets.

Do you list all free bets?

There are lots of bookmakers who operate in the UK and internationally. Anyone can use our free bet calculator and we do provide an ever-expanding list of bookmakers who offer a variety of free bets. We will only list bona fide bookmakers who are allowed to operate and have a license for the UK market. You can register with multiple bookmakers and gain access to multiple free bet offers, but please only gamble responsibly and ensure that you are not exceeding your personal limits as the free bet offers do normally require a deposit of real funds.

What is the best bookmaker offer?

The Bet Calculator provides an ever-increasing list of free bet offers, however we do not advise our customers on the ‘best’ bookmaker offers since we consider all of the offers we provide to be of good quality. We advise that you choose the free bet offer that suits you best. This might not always be the highest amount, as smaller bet offers are often subject to fewer restrictions and the funds can be redeemed more easily, so you may wish to try multiple bookmakers and revisit our free bet offers page to keep up to date with the latest offers.

Can I use free bets if I am already a customer?

The majority of our listed free bet offers are for new customers, however that does not mean that you will not find free bets for existing customers. Many of the bookmakers we list also provide free bet offers to their existing customer base. Bookmakers are always looking for new customers with free bets, however they are aware that offering free bets to new customers may annoy their existing customer base, therefore they also run promotions and free bet offers for existing customers. Once you are a customer of a bookmaker and you have used your free bet offers, you should log back into the account and check to see the latest free bet offers for existing customers.

What are the main differences between free bet offers?

Listed below are the variables that may apply to the bet offers listed on the bet calculator:

  • Deposit size.
  • The size or amount of your stake.
  • The bet your free bet is eligible for - Some bookmakers insist that the offer applies to your first bet only and others enable you to use it on multiple bets.
  • The odds that your bet is offered at - Usually there are minimum odds that apply to free bet offers.
  • Does the offer apply to a specific event or a specific type of sport.
  • Free bet offers may sometimes only be valid for a certain type of bet, ie a single, double or goliath. The Bet Calculator offers explanations for each different type of bet as they are selected.
  • Time limitations of free bets.
  • Withdrawals from free bet offers can sometimes be limited if a certain number of bets have not been placed.
  • Free bet offers sometimes require funds to be deposited in a certain way to ensure eligibility.
What does ‘matched deposit’ mean?

A matched deposit means that the bookmaker will match the amount you deposit with the same amount of credit on your account for you to turn into a stake. In most instances the amount that you are credited with will correspond directly to the amount that you initially deposited. Also referred to as a ‘free bet matched deposit’, the more you deposit, the more you will receive from the bookmaker, however there is usually a maximum level that will apply to this kind of offer. Another way in which bookmakers present this offer is as a ‘100% deposit bonus’.

What are ‘cashback welcome offers’?

Bookmakers may sometimes run ‘cashback welcome offers’ - this is another way of saying ‘deposit bonus offer’, as a cashback welcome offer will not typically provide any cash that can be immediately withdrawn. These offers vary in type and style, in some cases the bet offer may be triggered after a certain volume of bets have been placed, whereas in others after a certain amount of time has elapsed since registering with the bookmaker. Once again, you should read the cashback welcome offer terms and conditions to fully understand when an offer might be triggered so you can ensure that it is the correct offer for you.

What are ‘first bet matched offers’?

Also referred to as ‘free bet matched stake offers’, your first bet will be matched with an equal amount when you register with a bookmaker. With this bet offer you will normally find a maximum level for the matched offer. You may also find that you have to bet the precise amount specified in the bet offer. So for instance if the bet offer is for £100, and you stake a lower amount, say £50, the offer may not be triggered. Bookmakers also often only match first bet offers when the odds are above a certain level, for instance 2/1.

What is a ‘risk free welcome offer’?

‘Risk free welcome offers’ are now very rare due to the fact that nearly all stakes involve an element of risk, and there are very strict regulations around how bookmakers can describe or market free bets. Bookmakers may reward their customers with a risk free bet, but in reality this would only happen after a customer has already placed a stake (i.e. taken a risk). It is fair to say that risk free offers do exist, however they are usually provided as rewards to customers who have already triggered a certain volume of bets, stakes or losses. In many instances where risk free bets are offered the winnings cannot be immediately withdrawn and banked. Risk free bets will often lead to a credit on your gaming account which in turn can be staked, with the funds only withdrawable after you place another bet. While it is our opinion that bookmakers do make the effort to label their bet offers fairly, the offers are sometimes over-simplified as the bookmaker needs to condense the details of the offer into a short headline.

What is a ‘free bet credit’?

This is the most broadly encompassing term for a free bet offer covering many betting offer types. When claiming a ‘free bet credit’, you really do need to look at the terms and conditions, as a free bet credit can be triggered by almost any variable listed above under ‘free betting offers variables’.

What are ‘enhanced odds sign up offers’ & ‘price boosts’?

‘Enhanced odds sign up offers’ and ‘price boosts’ are rising in popularity as bookmakers are increasingly running offers relating specifically to particular events (i.e. enhanced odds on the Grand National or Royal Ascot) to encourage new customers to create accounts and bet on these events. We advise that you look into when the winnings can be withdrawn, as some bookmakers will stipulate that winnings must be restaked before they can be withdrawn from the bookmaker account. They might also put limits on the stake, so if for instance the normal odds would be 3/1 and they have been enhanced to 10/1 the bookmaker may stipulate that the free bet is for a maximum amount of £2. These bets can be useful though especially if you intend to place your winnings on a subsequent single bet, which would effectively equate to an enhanced double accumulator bet.

What are ‘profit boosts’?

A ‘profit boost’ is very similar to a ‘price boost’ free bets, as the end result is effectively the same; you get more money in your account to stake on subsequent bets. Profit boost offers provide additional profits based on a successful bet. Typically a profit boost free bet offer will double the profit on a successful bet. Bookmakers will often refer to a 100% profit boost on your first bet, however this may apply to any number of bets.

What are ‘money back free bets’?

Bookmakers sometimes offer ‘money back special bets’ for specific events or races. In sports betting this adds an additional element to the bet, for instance you may get your money back if a particular player scores a goal in a football match, or you may be offered your money back in a horse race if a horse does not finish the race. These types of bet offers are usually available to everyone and not restricted to new players. With this type of bet the money back is usually money credited to your gaming account which then needs to be re-bet before it can be withdrawn.

Bonus codes and promo codes

Free bets are often available to all new customers, however to qualify for a free bet sometimes you will need to apply a promotional code. On the bet calculator we always list the promo code in either the bet offer box or underlined in the terms and conditions. The bet offer links listed on the bet calculator always open in a new tab on your browser, so you can very easily check that you are using the correct promo code to enable you to claim your free bet offer.

Mobile specific free bets & betting app offers

Bookmakers are encouraging new customers to sign up via mobile devices as they want their customers to have access to gaming services from the mobile phone in their pocket. In some instances free bets are made available only if a customer registers their new betting account via a mobile device. Registering via a mobile phone therefore holds an advantage of registering via desktop as it maximises the number of offers available. It is therefore worth keeping an eye out for mobile only offers as they can often give you better terms and larger returns if you win.

Free betting additional FAQs

Can I get multiple free bets?

Bookmakers will normally restrict you to one, possibly two free bets when you register with them. You can usually only register one account per bookmaker. Bookmakers try to disallow you having multiple accounts to take advantage of their offers over and over again. However, you can have as many different bookmaker accounts as you want. If you’d like to take full advantage of the free bet offers listed on The Bet Calculator we recommend you have more than one bookmaker account. This may also benefit you as bookmaker odds do vary. Having multiple accounts will also enable you to choose which bookmaker has the best odds for any given choice of bet.

When can I use my free bet?

Unless your free bet is specific to an event it should be usable immediately. You may need to verify your account if the free bet is with a new bookmaker, but normally as soon as you have completed the bookmaker registration process your free bet should be available within your account. Bookmaker support services are often very good, and many bookmakers provide a chat function, so if you have questions regarding your free bet you should be able to contact the bookmaker directly.

How do I withdraw my winnings?

Bookmaker terms can vary, however if you make a straight bet without any betting offers then the winnings are usually available for you to withdraw immediately. If you have used a free bet of almost any type the returns are likely to be subject to rules and regulations. The bookmakers often require you to roll the winnings into another bet, and they may ask for this to be done multiple times before they pay out or allow you to withdraw on any funds.
