Formula

How the hedge is calculated

  1. 01

    Bonus winnings

    Free bet payout = value × (odds − 1). The bonus stake isn't returned.
  2. 02

    Hedge stake

    Hedge stake = value × (bonus odds − 1) / hedge odds. This balances the net returns.
  3. 03

    Locked-in result

    Net return = hedge stake × (hedge odds − 1). Conversion = net return / bonus value.

Example

Example: $100 free bet at 5.00

Questions

Frequently asked questions

How is a free bet different?

A stake-not-returned bonus pays profit only. A $100 free bet at 5.00 pays $400, not $500. Higher odds can improve conversion, subject to bonus rules.

Why is the calculated return the same for both outcomes?

An opposite bet using your own funds balances the net return. It's the arbitrage mechanism with a free bet as one leg, assuming both bets settle as expected.

How much of the bonus can I convert?

It depends on both prices and the sportsbook's bonus rules. The calculator shows conversion at your entered odds. Read the bonus terms before betting.
