How it works

A bet-and-get offer pays a fixed amount of bonus bets for placing a small cash bet. The headline number is face value. Bonus bets pay only their winnings, so they're worth what you can convert them for: about 70%.

Some offers pay the bonus whatever happens to the qualifying bet. Others pay it only if that bet wins, and then you only collect some of the time. The two look the same in an ad, so check your book's current terms and pick the matching option above.

The result is the whole promo: the qualifying bet's own expected value plus what the bonus adds.

How much is bet $5, get $200 worth?

The calculator above starts with an example: $5 at +120, when a sharp book has the same side at +130 / -150, and $200 in bonus bets converted at 70%. Converted, the bonus bets are worth $140. The $5 bet on its own is worth -$0.38.

If the bonus is paid whatever happens, the promo is worth $139.62. If it's paid only when the bet wins, you collect it 42.0% of the time, and the promo is worth $58.45.

What should I bet when the bonus needs a win?

The side most likely to win. The bonus is worth far more than the $5, so the chance of collecting it matters more than the price. Take a favorite at -420 when a sharp book has it -400 / +320: it wins 77.1% of the time, and the same offer is worth $107.66. Check whether your offer sets minimum odds for the qualifying bet first.
