How to Use This Calculator
Enter decimal odds for two mutually exclusive outcomes and your total stake. The tool splits stakes so that if either wins, you collect roughly the same return (before commissions).
Decimal odds only
Both prices must be in decimal format (> 1.00). Convert American prices with our converter if needed.
Total stake
This is the full amount you risk across both legs. Individual stakes sum to the total.
Read both stakes
Place exactly those amounts on each outcome at the quoted odds. Slippage changes the picture.
Check for margin
If implied probabilities sum to more than 100%, you are paying vig—dutching still balances returns but does not create arbitrage by itself.
What Is Dutching?
Dutching splits a fixed bankroll across several outcomes so the payoff is equal (or nearly equal) whichever wins. It is common in horse racing with multiple credible chances, and in two-way markets when you want balanced exposure.
Stake Split Math
Let O1, O2 be decimal odds and S the total stake. With implied weights 1/Oi, stake on leg i is S · (1/Oi) / (1/O1 + 1/O2).
Si = S × (1/Oi) / Σ(1/O)
Worked Examples
Example 1 — Defaults on the tool
Odds 2.10 and 2.05, total stake $100. The calculator returns stakes ≈ $49.38 and $50.62 with a balanced return either way—verify in the live widget.
Example 2 — Tighter prices
Odds 1.90 and 1.90, stake $200. Each implied prob ≈ 52.6%, sum > 100%—the book has margin, but dutching still equalizes your return across the two sides you choose.
Example 3 — Three-way markets
This two-leg version covers win/lose splits in binary markets. For three outcomes you need three prices and a wider solver—see related arbitrage tooling.
When It Breaks
Non-runners, rule-4 deductions, and exchange commission all change effective odds. Always reconcile stakes with what the ticket actually locks in.
Frequently Asked Questions
Not necessarily. Dutching balances stakes across outcomes you choose. Arbitrage typically means the combined implied probability is below 100% so profit is locked—use the arb calculator for that test.
This screen expects decimals. Convert first, then paste.
Rounding, exchange fees, and cash-out rules create gaps. Treat the output as a target before you confirm tickets.
You remove outcome uncertainty among the legs you cover, but you still lose the stake if none of your picks wins or if a void occurs.
Yes, but you need three odds inputs and the same proportional rule. This page implements two legs for speed.
