How it works
The free calculator converts every price to a reciprocal weight, then divides the total stake in proportion to those weights. Shorter odds receive a larger stake so each listed outcome targets a similar gross return.
Worked examples
Two-way Dutching example
With odds of 2.40 and 3.00 and a 100-unit budget, the calculator allocates about 55.56 units and 44.44 units. Either outcome targets a return of roughly 133.33 units and a theoretical profit of 33.33 units before costs.
Three-way allocation
Odds of 3.00, 4.00 and 5.00 total 78.33% implied probability. A 100-unit budget is split approximately 42.55, 31.92 and 25.53, targeting about 127.66 units back.
Limitations and interpretation
Outcomes must be mutually exclusive and collectively match the market being modelled. Rounding, missing outcomes, void rules, dead heats, fees and price changes can alter results.
