What is dutching?

Dutching is very similar to regular matched betting. Instead of covering all outcomes with back and lay bets, you cover them with only back bets.

An alternative to laying

Dutching is helpful when placing the corresponding lay bet at an exchange is not possible. For example, Smarkets have different tennis retirement rules to many bookmakers. In that instance, your back and lay bets are not exact matches, which means your money is at risk. It could also be that no lay market is available due to the exchange not covering the event, like some esports tournaments.

Arbitrage dutching

There are also situations where you can use dutching to find an ‘arbing’ opportunity. These arise when bookmakers set their odds too high compared to other bookmakers. Due to the high odds, you can cover all outcomes and lock in a profit without needing a free bet or other promotion. These occurrences are rare and short-lived, as bookmakers will quickly adjust their odds to line up with everyone else, thus removing the opportunity.

My complete guide to dutching details when and how to use this technique.

How to use this calculator

To use this calculator, enter the odds of the selections you’ve found. Once done, you’ve got several options for the calculator to work out your stakes by selecting one of the following in the ‘Target’ dropdown.

First Selection

Use this option when you want the stake field to be the amount you stake on your first selection. The calculator works out all the other stakes based on this. ‘First Selection’ mode is useful when you must stake a certain amount on one of the selections, such as maxing out the amount you’re allowed to bet on that outcome or using a free bet of a specific value.

In ‘First Selection’ mode, you can choose either ‘standard’ or ‘free’ bet types. Select ‘Free Bet’ if your first selection is a free bet where you do not get your stake returned with any winnings. The calculator will adjust your other stakes accordingly.

Total Stake

‘Total Stake’ mode will consider the amount you enter into the ‘stake’ field to be the total amount you want to stake across all outcomes. When you have to work within a limited bankroll, use this option.

Overall Profit

‘Overall Profit’ mode considers the amount in the stake field to be the profit you would like to make. The calculator will provide stakes to achieve that profit regardless of the event’s outcome, which is great if you have a specific target.

Odds format

This calculator allows you to enter your odds in multiple formats. Use the ‘Odds Format’ dropdown above the calculator to switch between decimal, fractional and moneyline.

What is matched betting?

Dutching is part of a greater whole we call ‘matched betting’. In general, it is a way of exploiting bookmaker promotions to make a predictable profit from each one. By covering all outcomes of an event, you can meet the requirements for claiming free bets or bonuses while your bets cancel out, resulting in an overall profit or loss close to breakeven. You can then repeat the process to extract about 80% of the free bet amount. For example, you can earn about £8 profit from a £10 free bet.

My comprehensive and free Matched Betting Guide will take you through the basic concept with a complete walkthrough of your first bookmaker promotion. You’ll even earn about £15 in the process.

Beyond that, my Matched Betting Academy details how to profit from every UK bookmaker’s ‘welcome’ offer, all for free. Designed and tested by matched betting experts, it also provides techniques to make money from extra place offers, 2UPs, price boosts, and other recurring existing customer offers, all logically structured and well-paced.
