How to Turn Free Bets Into Cash (The Smart Way to Use Sportsbook Free Bets)

If you’ve started exploring matched betting, you’ve probably noticed that sportsbooks give away a surprising number of free bets.

At first glance, these offers seem straightforward. The sportsbook gives you a free bet and you use it to place a wager.

But there’s a catch.

When a free bet wins, you usually don’t receive the stake back—only the profit. Because of this, many casual bettors end up using free bets inefficiently and get far less value from them than they could.

Matched bettors take a different approach. Instead of gambling with free bets, they use a simple process to convert them into real cash while minimizing risk.

In this guide, we’ll show you exactly how that works and how users at Oddsmatched.com consistently turn sportsbook free bets into withdrawable profit.

What Is a Free Bet?

A free bet is a promotional credit given by a sportsbook that allows you to place a wager without risking your own money.

Free bets are typically awarded through promotions like:

• Bet and get offers

• Risk-free bets

• Signup bonuses

• Loyalty promotions

• Odds boost rewards

For example, a sportsbook might run a promotion that says:

Bet $50 and receive a $50 free bet.

Once the qualifying bet settles, the sportsbook credits your account with the $50 free bet.

However, the way free bets pay out is different from normal bets.

The Key Rule Most People Miss

With a normal bet, if you wager $50 at odds of 3.0 and win, you receive:

$150 total return($100 profit + $50 stake)

With a free bet, the stake is not returned.

If you place a $50 free bet at odds of 3.0 and it wins, you receive:

$100 profit only

This is why simply placing a free bet like a normal wager is not the most efficient strategy.

Matched bettors instead use a method that extracts most of the free bet’s value.

The Goal: Convert the Free Bet Efficiently

When used properly, most free bets can be converted into 70–80% of their value as guaranteed profit.

For example:

Free Bet Value	Typical Profit
$25	$17–$20
$50	$35–$40
$100	$70–$80

The key is placing two opposite bets—one at the sportsbook and one at a betting exchange—so that the final outcome doesn’t matter.

This is the same principle used in matched betting.

Step-by-Step: Converting a Free Bet to Cash

Let’s walk through a practical example so you can see how the process works.

Step 1: Choose the Right Event

The first step is finding an event where the odds at the sportsbook and the betting exchange are close.

For example:

Platform	Bet Type	Odds
Sportsbook	Team A to win	4.00
Exchange	Lay Team A	4.10

Higher odds are often used for free bet conversions because they maximize the value of the free bet.

Tools at Oddsmatched.com help users quickly identify events where these odds match closely.

Step 2: Place the Free Bet at the Sportsbook

Now place your free bet on the selected outcome.

Example:

Free bet value: $50Odds: 4.00

If this bet wins, the sportsbook will pay:

$150 total payoutbut since the stake is not returned, you receive:

$150 – $50 stake = $100 profit

Step 3: Calculate the Lay Bet

Next, you place the opposite bet on a betting exchange.

This is called the lay bet.

The lay bet ensures that if your sportsbook bet loses, the exchange bet wins and covers the loss.

Using a matched betting calculator makes this step easy. You simply enter:

• free bet value

• back odds

• lay odds

• exchange commission

The calculator then tells you exactly how much to lay.

At Oddsmatched.com, our calculators automatically determine the correct lay stake so beginners don’t need to do the math manually.

Step 4: Place the Lay Bet

After calculating the correct stake, place the lay bet on the exchange.

At this point, both outcomes of the event are covered:

If the sportsbook bet wins:

• sportsbook payout occurs

• lay bet loses

If the sportsbook bet loses:

• lay bet wins on the exchange

Either way, the final result is roughly the same.

Step 5: Collect Your Profit

Once the event finishes and both bets settle, the free bet has been successfully converted into cash.

In most cases, the profit will be approximately 70–80% of the free bet value.

For example:

$50 free bet → about $37 profit

This is why matched bettors treat free bets as valuable assets rather than gambling opportunities.

Why Higher Odds Work Better

When converting free bets, higher odds are generally preferred.

Here’s why:

Because the stake is not returned, higher odds produce a larger potential profit when the bet wins.

This makes it easier to structure the lay bet so that the overall profit remains balanced regardless of the outcome.

Most experienced bettors look for odds between 3.0 and 6.0 when converting free bets.

Common Types of Free Bets

Not all free bets work exactly the same way.

Understanding the different types can help you convert them more effectively.

Stake Not Returned Free Bets

This is the most common type.

The stake is not returned when the bet wins.

These are the bets most commonly used in matched betting strategies.

Stake Returned Free Bets

In some promotions, the stake is included in the payout.

These are actually easier to convert and usually produce slightly higher profits.

Risk-Free Bet Refunds

Some sportsbooks offer risk-free bets where your stake is refunded as a free bet if the wager loses.

This essentially creates the same opportunity to convert a free bet into profit.

Mistakes to Avoid When Using Free Bets

Beginners sometimes lose value from free bets because they rush through the process.

Here are a few mistakes to avoid.

Using low odds

Low odds reduce the conversion value of the free bet.

Forgetting exchange liquidity

Make sure there are enough bets available on the exchange for the lay bet.

Entering incorrect numbers

Always double-check the odds and stake amounts in your calculator.

Using tools from Oddsmatched.com helps eliminate most of these errors.

How Experienced Matched Bettors Maximize Free Bets

Advanced matched bettors constantly monitor sportsbooks for promotions that generate free bets.

These opportunities include:

• bet-and-get promotions

• odds boosts

• bet insurance offers

• loyalty rewards

• seasonal promotions during major sporting events

By tracking these promotions across multiple sportsbooks, bettors can convert dozens of free bets each month.

Over time, this steady stream of free bets becomes a reliable source of side income.

Why Free Bets Are the Core of Matched Betting

Matched betting ultimately revolves around one thing: extracting value from sportsbook promotions.

Free bets are the most common form of that value.

When used correctly, they provide consistent profit without requiring you to predict sporting outcomes.

That’s why experienced bettors treat free bets less like gambling credits and more like discount coupons that can be converted into cash.

Final Thoughts

Free bets are one of the easiest ways to generate profit from sportsbook promotions, but only if they’re used strategically.

By placing a matched lay bet on a betting exchange, you can convert most free bets into real cash regardless of how the game ends.

With the right tools, the process becomes quick and repeatable.
