The Sequential Dutching Calculator can be used to make risk-free profit from accumulator bets where you don’t want to use your betting exchange to lay the individual legs, but rather different bookmakers.
You would do this for example for tennis acca offers where due to the different tennis retirement rules, you cannot use a betting exchange.
First Look
In the second screenshot further down, you can see what the calculator looks like with all the details filled in.
As an example, we have used a four-fold accumulator, but the calculator can be used for accumulator bets with up to six selections. The only requirement is that the different events must not overlap, i.e. each leg of the accumulator bet must have finished before the next one starts. They must not overlap because the outcome of the last leg determines how much you have to place on the next game or whether you should stop placing bets. So the outcome of the first game determines the action you need to take on the second game.
The way this calculator is designed, you should dutch each leg individually, i.e. after placing the whole accumulator bet with your first bookmaker, you should place a bet on the opposing outcome of the first leg with a second bookmaker (if the first leg of your acca with Bookmaker 1 is on Player 1 of a tennis match, you should place a bet on Player 2 with the second bookmaker for the first leg) and wait for the outcome.
Note: ‘Bookmaker 2’ doesn’t have to be the same for all legs; you can use any number of different bookmakers for the different legs.
Only if the first leg of your accumulator bet wins, should you place an opposing bet on the second leg. As soon as one leg of your accumulator bet loses, you should stop dutching.
We can illustrate this with the screenshot below.
In this example, your first leg won, resulting in a loss with Bookmaker 2 of €33.46 (your first stake), and then the second leg lost. Your accumulator bet with Bookmaker 1 has now lost, which is shown in the Bookmaker 1 column as €-50.00 (your lost stake). Your second stake provided by the calculator was €54.04, and at odds of 2.50, your net win with Bookmaker 2 is €81.05. Overall, this results in a loss of €2.41, which is the same for all the outcomes.
If all the legs were to win, it would result in the outcome you can see in the last line above. You would lose all your Bookmaker 2 stakes, but win with Bookmaker 1, again resulting in the same overall loss.
With this approach, you will ensure an equal profit/loss whatever the outcome. This will be explained further in the profit breakdown section below.
Please note: the calculator needs all the details for all the individual odds and commissions to work out even your first Bookmaker 2 stake, so you need to enter them right at the start, in chronological order, even if you’re only placing your first opposing bet initially and may not need to place any others.
Row Items
Light Blue Section
Stake: enter your back stake with your first bookmaker (Bookmaker 1) here.
Total Odds: enter the total odds. This should be displayed on your bet slip and is calculated by multiplying all the back odds for the individual selections by each other.
Legs: the number of selections in your accumulator bet. You can choose anything between 2 and 6 legs.
Commission: enter 5% if your bookmaker deducts the German betting tax.
Dark Blue Section
Leg: the numbers of your individual selections, in the order the events are going to take place.
Odds: enter the individual odds for your selections with Bookmaker 2 (which can be several different bookmakers). Whenever you need to place a bet for an extra leg, make sure to re-check the odds at the respective bookmaker and enter the new odds into the calculator to work out a revised stake for your next selection.
Commission: if the respective bookmakers that you are using for the different legs charge the German betting tax, enter 5% here.
Recommended Stake: all the recommended stakes will be worked out for you by the calculator, and you can proceed to back the first selection. Note that as explained above, you should only back the second leg if and when the first leg has won (lost with Bookmaker 2), and after recalculating with the potentially changed odds for the second selection.
Profit Breakdown Section
In this section, you will see detailed amounts of all the possible outcomes of your bets.
Bet Outcome: the potential outcomes of the accumulator bet. A red L means that the back selection has lost, in which case you should stop placing further bets, and this will conclude the accumulator bet. A green W means that this leg of your accumulator bet has won, and you will go on placing further bets until one selection loses. If all the selections win, there will be a row of green Ws, and your bet with Bookmaker 1 will win.
Bookmaker 1: as all of the selections have to win for your accumulator bet to win with Bookmaker 1, this column shows your lost stake in all the cases where one leg has lost, and your back win if all your selections have won (back commission deducted).
Bookmaker 2: this column shows your winnings with Bookmaker 2 if the selection loses (commission deducted), and your loss with Bookmaker 2 (your stake) for the individual legs if the selections win.
Total: the totals of the respective rows are shown here. They are the same for all the possible outcomes.
