Free promotion math tool
Bonus bet conversion calculator
Estimate a hedge stake, locked cash profit, and conversion percentage for a stake-not-returned bonus bet.
Assumes the bonus-bet stake is not returned and the hedge is placed on the exact opposite outcome at a different book.
Promotional terms, limits, voids, price movement, and stake-return rules vary. Read both books’ terms before using a hedge.
What the result means
Use the number as an estimate
A stake-not-returned bonus bet pays only the profit when it wins. Hedging the exact opposite outcome can equalize the two results, but the achievable conversion depends on both prices and the promotion rules.
A $100 bonus at +300 creates $300 of potential bonus profit. Hedging the opposite side at -275 requires about $220 and produces about $80 either way, before limits or movement.
