What is a Dutching bet

Dutching is a staking method used to share the financial risk across multiple selections. This way of staking will result in a winning bet returning the same monetary gain regardless of which of the selections wins. The term Dutching is believed to have come from the name of a 1920’s gangster that ran a numbers game (along with other activities that were illegal at that time), his name was Arthur Flegenheimer but went by the name Dutch Schultz.

Methods for Dutching betting

Although its name is attributed to a gangster Dutching is not an illegal staking system in the slightest. In fact it is a system used in general by a punter that is risk averse and sometimes by gamblers that are happy to grind out a small guaranteed profit by backing all the selections in an event with several different bookmakers at odds that mean no matter what the outcome a greater financial return will occur. This is normally a short sighted way of gambling as on some occasions one of the selections picked will be voided because of a palpable error on the bookies part that enabled the combination of bets to return a profit or Dutching will result in a restriction on the amount you can bet with a particular bookmaker as you are always taking odds that are out of line with the rest of the industry. If Dutching is a staking system that appeals to you then it’s recommended you stick with bets on the betting exchanges and Asian bookmakers as these type of betting companies encourage this kind of activity.

Other than lowering risk and grinding out small profits Dutching can also be used to effectively Lay a betting selection. This is because a Lay bet is the same as backing all other selections. So staking all but one selection in a given event to a level profit is the same as Laying that one selection. This method of Dutching will normally be used for sports events that has minimal liquidity on the betting exchanges or isnt even offered, which happens often on all but the major sporting events.

Here are a host of the best betting exchanges and Asian bookmakers you should sign up to if you wish to get involved in Dutching.

Dutching calculations

Dutching calculations differ slightly depending on the number of selections that are being combined, but the basic underlining principle is the same. Using our Dutching calculator we have given you a couple of different options.

First is to multi-back selections, giving an equal profit, based on an initial bet. For example, if you have already backed horse A with a £10 bet, but now want to bet on horse B and C, the calculator will tell you how much you need to bet so that if any of the horses win you will have the same profit.

The second method is to Dutch to a maximum liability. To do this you need to click the “Total Stake” radio button and enter the total amount you are willing to bet. The calculator will then distribute this amount amongst the number of selections you have chosen. Again giving you the same amount of profit regardless of the selection that wins.

The basic formula for Dutching is,

Where

S = Selections implied probability
T = Total selections implied probability
L = Liability (the total amount of money you’re willing to bet)

Stake = (S/T)*L

This works very easily if you are using the second method of Dutching (to a fixed liability). But if you have already placed a single bet, and now wish to Dutch you will have to do a bit of manipulation with this formula. You will have to first find out what your liability will be based on this first bet. The formula need to do this is

L = Stake/(S/T)

Now you have the liability you will work out the individual stakes for the other selection is the same way as before.

Example of how our Dutching calculator works

I’m pretty sure the previous section was hard reading and didn’t completely cleared Dutching up for you. So as with all maths related problems, it’s best to look at an example. We will do show you both methods based on the same selections. Let’s say you fancy 3 different horses in Grand National, at odds of 5, 10 and 25. For now let’s also say you haven’t placed any bets yet and that you have decided you want to bet £50 on the race.

The first thing to do is work out the implied probability of each selection

For horse 1 = (1/5) x 100 = 20
For horse 2 = (1/10) x 100 = 10
For horse 3 = (1/25) x 100 = 4

Now we can fill this data into the formula we have. Stake = (S/T)*L

Horse 1 stake = (20/(20 + 10 + 4)) x 50 = £29.41
Horse 2 stake = (10/(20 + 10 + 4)) x 50 = £14.70
Horse 3 stake = (4/(20 + 10 + 4)) x 50 = £5.88

So now you know how much to back each horse if you want to win the same regardless of which horse wins (because money is limited to 2 decimal places the winning amount might vary by one or two pence)

Using the same selection of horses for this example, let’s say you have already bet horse 1 to win, placing £25 on it. But now decided you also like the look of horse 2 and 3. How do you work out the correct amounts to bet to have a level profits pay-out?

This is where we need the rearranged formula. L = Stake/(S/T)

L = 25/(20/(20 + 10 + 4)) = £42.50

The total liability for the 3 bets will be £42.50, now this can be used in the same way as before to find the correct staking amount.

Horse 2 stake = (10/(20 + 10 + 4)) x 42.50 = £12.50
Horse 3 stake = (4/(20 + 10 + 4)) x 42.50 = £5

As you can see with these two examples the maths behind dutching isn’t that complicated, but it can get a bit boring if looking to dutch many selections, so feel free to keep coming back and use our readymade Dutching calculator.
