Dutching turns several opinions about one event into a single position with a known profit and a known maximum loss. It is popular in horse racing and football because those markets have many outcomes, which creates pricing gaps between bookmakers that a dutch can exploit.
How It Works
The calculator divides your total stake in proportion to each selection's implied probability (1 ÷ decimal odds). Each stake is: Total Stake × (1 ÷ odds) ÷ Sum of (1 ÷ odds) across all selections. Because stake × odds is then identical for every leg, any winner returns the same amount. Your profit margin equals 1 ÷ sum of implied probabilities − 1: dutch 2.50 + 3.00 (73.3% combined) and you make about 36% on turnover; if the sum exceeds 100%, every outcome locks in a loss.
Benefits of Dutching
Spreads risk across several outcomes: you no longer need to be right about one selection, only about a group of them.
Equalises profit — whichever covered selection wins, the return is identical, so the result is predictable in advance.
Exploits open markets: in races or matches without a dominant favourite, combining mid-priced selections often beats backing one at a short price.
Practical Applications
Horse racing: back the two to four genuine contenders in a competitive handicap and let the outsiders lose for you.
Football correct scores: cover the three or four most likely scorelines (e.g. 1-0, 2-0, 2-1) in a match with a clear favourite.
Tennis set betting: dutch the plausible set scores for the favourite (e.g. 2-0 and 2-1) instead of taking a cramped match-winner price.
Common Dutching Mistakes
Dutching too many selections — each added selection reduces profit margin; stick to 2-4 outcomes maximum for meaningful returns
Ignoring the combined overround — if the total implied probability exceeds 100%, dutching guarantees a loss regardless of stake distribution
Placing bets at different times — odds change rapidly, so place all dutching bets within seconds of each other to avoid drift
Dutching Examples
Two-Selection Dutching
A football match offers 2.50 on the home win and 3.00 on the draw. Dutching both with a $100 total stake splits it into $54.55 on the home win and $45.45 on the draw; either result returns $136.36, a profit of $36.36 (36.4% ROI). Remember this is not risk-free: if the away side wins — the uncovered outcome — you lose the full $100 stake.
Three-Way Horse Racing Dutch
Three horses have odds of 4.00, 5.00, and 6.00. With a $60 total stake, the calculator distributes: $24.32 on the 4.00 selection, $19.46 on the 5.00, and $16.22 on the 6.00. Each outcome returns $97.30 — a profit of $37.30 (62.2% ROI). The more selections you add, the lower the overround needs to be for dutching to remain profitable.

Dutching Value Spots Across Bookmakers
Bookmaker A prices Team X at 3.50 while Bookmaker B has Team Y at 3.80. Taking the best price on each selection, the combined implied probability is just 54.9%. Dutching $200 puts $104.11 on Team X and $95.89 on Team Y; either winner returns $364.39, a profit of $164.39. Shopping for the best odds on every leg is what creates margins like this — no single bookmaker offers them.

Dutching aims for equal profit across multiple selections within the same market (e.g., backing 3 horses in a race). Arbitrage covers all possible outcomes across different bookmakers to guarantee profit. Dutching doesn't guarantee profit - you still lose if none of your selections win.
Yes — dutching works at bookmakers and on betting exchanges alike. On an exchange, deduct commission from each selection's net return before comparing: effective decimal odds are roughly 1 + (odds − 1) × (1 − commission). A 5% commission turns 3.00 into about 2.90, which can flip a marginal dutch from profitable to losing.
Most dutches use two to five selections. Each added selection raises your strike rate but shrinks the profit margin, because its implied probability joins the total. A useful rule: only add a selection if you genuinely believe it can win — adding 'insurance' outcomes you don't rate simply taxes the profitable ones.
