Understanding Dutching
Spread your stake intelligently across several outcomes
🎯What is Dutching?▼
Dutching means spreading your stake across several outcomes of the same event, so that you win the same amount whichever one wins.
The name comes from Dutchy Schultz, an American gangster of the 1930s who used this technique at horse races to maximize his winnings while limiting risk.
It's a strategy that's particularly useful when you've identified several plausible favorites and want to cover yourself without having to choose.
💡A concrete example▼
Horse race: 3 plausible favorites at odds 3.0 / 4.0 / 6.0.
Total stake: 100€
🥇 Horse A (odds 3.0) → stake 44.44€
🥈 Horse B (odds 4.0) → stake 33.33€
🥉 Horse C (odds 6.0) → stake 22.22€
Result: whichever horse wins, you always get back 133.33€ (i.e. +33€ profit).
The higher the odds, the less you stake. The distribution is inversely proportional to the odds.
📖Terms to know▼
Total stake
The amount you commit in total, spread across all selected outcomes.
Guaranteed payout
The amount recovered whichever outcome wins (identical for all).
Net profit
Guaranteed payout - total stake. This is your real assured profit.
ROI % (Return On Investment)
Profit / total stake × 100. Indicates the dutching yield.
RTP (Return To Player)
1 / Σ(1/odds) × 100. Overall market quality. If RTP > 100%, it's a surebet.
🚦The 3 possible verdicts▼
SUREBET (RTP ≥ 100%)
Mathematically guaranteed profit. This happens when the odds of different bookmakers diverge enough. Rare but very interesting.
ACCEPTABLE (RTP 95-100%)
You lose a little on average (the book's margin), but it's still usable to cover or unlock a bonus.
LOSING (RTP < 95%)
Bookmaker margin too high. Dutching not profitable in the long run.
🔢Step-by-step guide▼
Choose your mode: Total stake (how much you want to commit) or Target profit (how much you want to win)
Enter the amount matching the chosen mode
Select the number of outcomes to spread across (2 to 8)
Enter the odds of each outcome (you can rename the label to keep track)
The stakes to place and the guaranteed payout calculate automatically
Look at the verdict: surebet = assured profit, acceptable = coverage OK, losing = pass
🤔When to use Dutching?▼
🏇 Horse racing
Several plausible favorites, no certainty about the winner.
⛳ Golf / Tennis (tournaments)
3-5 favorites to win a tournament, impossible to choose between them.
⚽ Grouped correct score
Bet on several plausible scores of a match (1-0, 2-0, 2-1...).
🎁 Unlock a bookmaker bonus
Reach a wagering target (rollover) with minimal risk.
💎 Multi-book arbitrage
When the odds of 2-3 bookmakers diverge, dutching can become a surebet.
Pro tips
📌 The more outcomes you add, the lower the RTP drops (cumulative margin)
📌 Profitable dutching exists: look for divergences between bookmakers
📌 Round the stakes up to the nearest euro on the favorite to simplify
📌 Limit to 2-4 outcomes in practice — beyond that the RTP explodes
📌 Check that all bookmakers accept your stakes before spreading
📌 Ideal for unlocking a bonus with controlled risk
📌 Beware of cash refunds (draw in football) which break the calculation
