Why the Traditional Unit System Fails
Betting on a race with a flat unit is a rookie mistake; you either bleed cash on a longshot or leave profit on the table when the favorite wins.
The Core Idea of Dutching
Take multiple selections, spread your stake so each wins the same net profit — no matter which horse crosses first.
Calculate the Implied Probabilities
First, flip the odds into decimals, then invert: 5.0 odds become 0.20, 3.5 odds become 0.2857. Those are your raw probabilities.
Normalize to a Total of 100%
Sum the raw numbers, divide each by the sum, then you have the share each horse deserves.
Staking the Dutching Way
Here is the deal: you decide your total bankroll for the race — say $200. Multiply $200 by each horse’s normalized share, and you’ve got the exact stake per runner.
Result? Every winning horse returns roughly the same $X profit, wiping out the usual variance.
When Dutching Breaks
Look: if you include a horse with odds beyond 20.0, the stake allocation becomes absurdly tiny, and any mistake in the odds calculation will wipe you out.
And here is why you must cap the number of selections — usually three to five, never more.
Practical Example
Imagine a three-horse race: 4.0, 6.0, and 10.0. Convert: 0.25, 0.1667, 0.10. Sum = 0.5167. Normalized shares: 48.4%, 32.2%, 19.4%. With a $150 pool, stake $72.60 on the 4.0, $48.30 on the 6.0, $29.10 on the 10.0. Win any, you pocket about $225 total, netting $75 profit.
Common Pitfalls
Do not ignore the bookmaker’s margin; the odds you see are already skewed, so the “equal profit” will be slightly lower than the theoretical maximum.
Also, avoid chasing the “sure thing” myth — no system guarantees a win, Dutching just levels the playing field.
Tools and Resources
Online calculators do the heavy lifting, but knowing the math keeps you honest when the software glitches.

Bottom-Line Action
Pick three horses, compute their implied probabilities, allocate your total stake accordingly, and lock in a uniform profit — simple, effective, and ready for tonight’s race. Stop overthinking, place the bets, and watch the profit equalizer work.
