For the same net result on both outcomes, the hedge stake is your original stake times its decimal odds, divided by the hedge decimal odds. A $100 bet at +750 (8.50) returns $850, so a hedge at +200 (3.00) takes $850 / 3.00 = $283.33. Either way you net $466.67 after both stakes. A smaller hedge keeps more of the original upside and protects less; this calculator shows the full, equal-return hedge.
