How to Use the Bet Calculator

It’s really simple.

The first thing you need to do is selection your bet type – the options cover everything from a single to a goliath.

Then decide whether you want the odds to be displayed in a fractional or decimal format.

After that, select your stake – i.e. how much money you want to bet.

You will then see three tick boxes. One called ‘each-way’, another ‘Rule4’ and the final one ‘Dead Heat’. We’ll explain what each of these means later on.

Finally, enter the odds as provided to you by your chosen bookmaker. If there are multiple selections you wish to make, enter the odds for each of them.

Then just click the big ‘Calculate’ button. Both your potential returns and profit will then be displayed.

Each-Way Rules

In horse-racing, an each-way bet is essentially two bets in one.

The first is a bet on your chosen horse to win. The second is a bet on your chosen horse to place.

If you choose a stake of £1, your total stake will be £2. £1 on the horse to win, and another £1 on it to place.

Obviously a win means finishing first. A place means finishing either first, or in one of a number of places – typically 2nd, 3rd or 4th. Make sure you check the place terms before making your bet.

The place terms for your bet include, the number of places the bookmaker will pay out on, and the fraction of the odds you will get if the horse does place. Usually 1/4 or 1/5.

In each-way betting, if your horse wins, you will win both the ‘win’ and ‘place’ parts of your bet.

But if it only places, you will lose the ‘win’ part of your bet and win the ‘place’ part of your bet.

This above tool acts as an each-way bet calculator. Simply tick the relevant box.

Rule 4 Rules

A Rule 4 deduction occurs when the winnings of your bet are reduced due to another horse being withdrawn from the race after your bet has been placed.

For example, if a horse pulls out of the race at the last minute, and is declared a non-runner.

The odds shown on any horse are based on all horses competing. If one backs out, the odds will change – even if you have already placed your bet.

Unfortunately, if this happens the odds are going to get shorter. So your potential winnings will go down.

The amount you can expect to have deducted from your winnings due to a Rule 4 varies depending on what the odds of the withdrawn horse were at the time it was withdrawn.

The table below shows the deductions which will be taken from your winnings. Note that even if multiple horses withdraw, the deduction will not exceed 90p in the pound.

Odds = Deduction

1/9 or less = 90p

2/11 - 2/17 = 85p

1/4 - 1/5 = 80p

3/10 - 2/7 = 75p

2/5 - 1/3 = 70p

8/15 - 4/9 = 65p

8/13 - 4/7 = 60p

4/5 - 4/6 = 55p

20/21 - 5/6 = 50p

Evens - 6/5 = 45p

5/4 - 6/4 = 40p

13/8 - 7/4 = 35p

15/8 - 9/4 = 30p

5/2 - 3/1 = 25p

10/3 - 4/1 = 20p

9/2 - 11/2 = 15p

6/1 - 9/1 = 10p

10/1 - 14/1 = 5p

Our Rule 4 bet calculator feature will help you work out exactly what your returns will be.

Dead Heat Rules

A dead heat occurs when two or more horses cross the finish line at the same moment.

If one of these horses was yours. You won’t win the full amount. Your winnings will be reduced depending on the number of horses who have dead-heated.

The amount paid out is normally calculated in the following way:

  • Dividing your total stake by the number of horses included in the dead heat
  • Multiplying that figure by the odds at which the bet was placed

But you don’t need to work it out yourself – our dead heat calculator feature will do it for you!
