Free Bet Conversion Calculator
Convert bonus bets into locked-in cash by hedging at another sportsbook.
Bonus Bet Conversion Calculator
A bonus bet conversion calculator tells you how much cash value you can realistically pull out of a bonus bet. That matters because a bonus bet is not the same as cash. When a bonus bet wins, you usually keep the profit but not the original stake, which means the true value is always lower than the face amount.
That is where a lot of people leak value. They see a $100 free bet and treat it like $100 in real money. It is not. The way to get the most out of it is to use the bonus bet on one side and hedge the other side somewhere else. A good bonus bet calculator shows the hedge amount, projected return, and conversion percentage so you can see whether the setup is actually strong.
If you are working through sign-up offers, promos, or sportsbook credits, this math matters. A sharp bonus bet conversion calculator helps you keep more of the promo instead of donating it back through sloppy execution.
This tool also goes by free bet converter or bonus bet converter — the books themselves use both terms, but the math is identical. A free bet conversion calculator compares the odds on your bonus side and hedge side and tells you the conversion rate: the percentage of the bonus's face value you lock in as real cash. Done well, a free bet converter typically returns 65-80% of face value, guaranteed, no matter which side wins.
Prefer not to do this by hand? AVO's bonus bet converter finds the best matching bet to convert your bonus bets into withdrawable cash.
Frequently Asked Questions
What is a bonus bet?
A bonus bet is sportsbook credit that can be used to place a wager, usually as part of a sign-up offer, promo, or retention deal. It looks like cash on the surface, but it is not the same thing.
The main difference is that when a bonus bet wins, you usually keep only the profit, not the original bonus stake. So if you place a $100 bonus bet at +100 and it wins, you receive $100, not $200.
That is why bonus bets have a lower real value than their face amount. Understanding that is the first step. Converting them well is the second.
How do you convert a bonus bet?
Bonus bet conversion means using the bonus bet in a way that turns as much of it as possible into real, withdrawable cash.
The standard approach is to place the bonus bet on one side of a market, usually at plus money, and hedge the other side at another sportsbook. For example, if one side is +300 and the other is -275 elsewhere, you can use the bonus bet on the plus-money side and hedge the opposite side with cash.
Done correctly, that structure lets you preserve a large percentage of the bonus bet's value regardless of the outcome. A bonus bet conversion calculator handles the hedge sizing and shows the projected cash return.
When should you use a bonus bet conversion calculator?
Every time you get a bonus bet.
Does not matter whether it is $10, $100, or more. The point of a bonus bet calculator is to help you avoid wasting promo value. The face amount can be misleading, and bad execution can burn a lot of expected value.
Most bettors want strong bonus bet conversion rates, and the calculator helps you find them fast. It shows the hedge size, estimated return, and conversion percentage so you can decide whether the setup is worth playing.
What is a good free bet conversion rate?
A well-executed free bet conversion typically locks in 65-80% of the bonus bet's face value as withdrawable cash. So a $100 bonus bet should reliably become $65-$80 in real money.
The rate depends on the odds you use: longer odds on the bonus side generally convert a higher percentage, because the free bet's stake (which you never get back) matters less to the total payout. The calculator shows the exact rate for any pair of odds before you commit.
