A bonus bet returns only the winnings, so hedge with stake = bonus x (D1 - 1) / D2. A $100 bonus bet at +300 hedged at -350 locks $66.67, a 66.67% conversion. A no-vig hedge, such as the other side on an exchange like Novig, raises the rate (Novig docs, checked 12 Nov 2026).

## Worked example

Conversion rate for a $100 bonus bet, hedged at a fair price

| Bonus price | Hedge price | Hedge stake | Locked profit | Conversion |
| --- | --- | --- | --- | --- |
| +150 | -170 | $94.44 | $55.56 | 55.56% |
| +200 | -230 | $139.39 | $60.61 | 60.61% |
| +300 | -350 | $233.33 | $66.67 | 66.67% |
| +500 | -600 | $428.57 | $71.43 | 71.43% |

```
hedge = B x (D1 - 1) / D2
profit = hedge x (D2 - 1)
conversion = profit / B
```

Because the bonus stake is not returned, a bonus bet is worth more on a longshot: the stake you lose matters less than the payout you gain. Conversion rates of 65-80% are typical on +300 to +500 prices with a tight hedge.

## How to use it

1. Enter the bonus bet amount and its price.
2. Enter the cash price on the other side.
3. Read the hedge stake, the locked profit and the conversion rate.

## Questions

### What is a good bonus bet conversion rate?

70% or more is good. It depends on how long the bonus price is and how tight the hedge market is.

### Why use long odds for a bonus bet?

The bonus stake is never returned, so a longer price keeps more of its value.
