What is a Free Bet Calculator?

As its name suggests, our latest gadget enables you to calculate the profit and returns from a fixed odds bet. Depending on the price you took or number of legs to the wager, crunching the numbers in your own head can be difficult. Our free bet calculator does all of the legwork for you, taking the fuss out of figuring out what you could win on online betting sites if the punt is successful.

How to Use My Free Bet Calculator

We’ve made this tool so easy to use that it only take just a few steps to see the worth of any wagers you want to make. Just follow these instructions if you’re doing it for the first time:

  1. Select the bet type you’re interested in or have placed from the list at the top.
  2. If you’ve done an each way bet, we’ve included a separate Yes / No option for that.
  3. Enter the stake and choose the Odds Format you want to see the bet calculated in.
  4. Now input the price. With fractional odds, there are separate boxes for the numerator and denominator.
  5. With any horse racing betting, add in any Rule 4 deduction if it applies to the wager.
  6. Pick the right option that applies to your bet from the Results box. This is either Won, Placed, Dead Heat, Lost or Void.
  7. All you have to do now is click on calculate to see total returns in the adjacent box next to the stake, while profits appear on the right-hand side.

Odds Format: Fractional Odds v Decimal Odds

Anyone offering a free bet calculator UK punters use must at least give you the choice between displaying fractional odds and decimal prices in the tool. Ours is no different. These are the two most popular formats and ways of expressing bets.

Dealing with fractions first, the numerator denotes the winnings relative to the stake from the denominator. Let’s say, for example, that a winning wager at 11/4 means you must bet £4 to make £11 profit. The key with fractional odds is to remember to add the numerator to the denominator in the ratio if you want to know the total returns. In our example, £4 + £11 = £15.

It’s easier for those punters who want to use our free bet calculator to work out payouts rather than profits with the decimal odds format. Staking £15 at 4.00 is just a matter of multiplying the stake by the available price. A winning wager here yields £60 as a total return.

The process of converting decimal prices into fractional ones helps you understand profit. That £15 bet with £60 returns is £45 profit. The ratio here is 3/1 as a fraction, but it’s not necessarily that easy doing the conversion. That’s why we provide a tool that displays both odds formats for you.

Popular Bets Available on the Free Bet Calculator UK Punters Use

Our gadget is so sophisticated that we have specific betting options available in detail across the top menu. More info is available on each of the following separate pages:

Explaining Bet Types

As noted above, there are various different wagers that you can use our free bet calculator to work out. We know the gambling world is opening up to more and more people, so this service is available across the following bet types:

Single Bet

It doesn’t get any simpler than this. A win single is where you bet on one thing happening. For instance, Arsenal to win in the outright Premier League betting at 100/30.

Each Way Bet

Certain markets allow you to wager on both an outright win and finishing placed. This is each way betting and at its most popular with punters who like horse racing. It doesn’t have to be that sport, though, as it’s also available on others. This is why we offer both a dedicated horse bet calculator and general each way function with our tool.

Place terms are entirely dependent on external factors like the type of event you’re betting on and number of possible winners. If it’s horse racing, then bookies may offer extra place racing. Typical fractions of outright odds are a quarter and a fifth, but others may be available on different sports.

We’ve built all that into our free bet calculator with an option you can select. The place terms at which an each way bet was struck rely on a set minimum number of runners taking part. If there are non-runners decreasing the entrants in a race, then revised terms may be offered.

For example, if fewer than eight runners jump off, then bookies may reduce the place terms from a fifth paying out on first, second and third to a quarter paying on first and second only. Whatever your bet is settled at, our tool is flexible enough to handle every scenario.

Double Bet

If you want to put two bets together and see what they’re worth, well now you can thanks to our multiple bet calculator option. A couple of wagers combined is called a Double and both legs must win for you to receive a payout. There’s greater potential to lose the bet as a result with the trade-off being the odds for the outcomes multiplied together giving you a better price.

For instance, Honeysuckle to win the Champion Hurdle at 9/4 and Altior to win the Champion Chase at Evens. A £10 stake on this double returns £65, £55 of which is profit, making the total combined odds for wager 11/2.

Treble Bet

Just think of a Treble as exactly like the Double but with one more leg in the wager. Once you have three selections on the betslip, combination and system bets are an option for you. A Trixie free bet calculator shows you what those would pay out as a Treble and three Doubles. Add in three Singles an you’ve got yourself a Patent.

Accumulator Bets

All wagers containing four or more legs is known as an Accumulator, or acca for short. Just like with those Doubles and Trebles, the total combined odds are multiplied for one selection to the next. Get all legs right and you can win big off a very small stake.

Use our free bet calculator Accumulator tool if you don’t believe us. It’s challenging getting an acca correct, though, so please manage your expectations and gamble responsibly. These are most popular as football accumulator bets, but can also be used for other and across multiple sports.

Lucky 15 Bet

A Lucky 15 free bet calculator does a lot of heavy lifting for you. A combination and system wager made up of four selections taken together as 15 bets in one as follows: 4x Singles, 6x Doubles, 4x Trebles and 1x Fourfold Accumulator. The crucial difference here between a straight acca and the Lucky 15 bet is that you need only leg to win for the bookies to give you a return.

Turning a profit depends on the prices taken. We strongly advise that you use a free bet calculator Lucky 15 tool to figure out how many aspects of the bet must be successful in order to make money on it. It’s complex maths to do in your head or even using pen and paper, but our gadget does all that for you.
