Use this free play calculator to work out the best hedge for your promotion and see how much of its value you can keep. Enter your free play amount and odds to calculate the hedge stake, locked in return, and conversion percentage before placing your bets.
Our free play calculator supports five currencies (USD, GBP, EUR, AUD, and CAD) and three odds formats (American, decimal, and fractional), while many comparable tools only calculate using US dollars and American odds.
What Your Freeplay Is Actually Worth

Free Play, Freeplay and What Other Books Call It
Free play and freeplay mean exactly the same thing. Sportsbooks use both spellings, so you’ll often see them used interchangeably even though the promotion works in the same way. With a free play, you keep any winnings if your selection wins, but you do not receive the original promotional stake back. Understanding that difference helps you calculate the true free play value, whether you’re using this freeplay calculator or another free play converter.
Many regulated US sportsbooks now describe these promotions as bonus bets instead of free plays. If that’s the terminology used in your account, use our bonus bet calculator because it’s designed specifically for that wording and promotion type. Some operators may also refer to the promotion as a free bet, but the calculation depends on the promotion’s terms rather than the name the sportsbook uses. Whether it’s called a free play or freeplay, this freeplay calc works when the promotion follows the same payout structure.
How to Use This Free Play Calculator
- Enter your free play bonus amount (e.g., $200).
- Enter the odds you’ll bet the free play on (prefer underdogs +150 or higher).
- Enter the hedge line – the opposite bet odds at another sportsbook.
- Click “Calculate Profit” to see your locked in return amount.
- Place both bets to lock in the same return.
Worked Examples
By setting the Free Play Size input field to $100 across both market scenarios, the tool calculates the exact hedge sizing required to lock in a completely equalized return regardless of which team wins the game.
Example A: Long Odds Underdog (Highly Profitable)
- Free Play Size: $100.00
- Free Play Line: +400
- Hedge Line: -400
- Hedge Bet: $320.00
- Profit: $80.00
- Conversion Rate: 80%
Example B: Short Odds Favorite (Inefficient)
- Free Play Size: $100.00
- Free Play Line: -110
- Hedge Line: +110
- Hedge Bet: $43.29
- Profit: $47.62
- Conversion Rate: 47.62%
The key takeaway for the reader is that because sportsbooks do not return your initial stake on promotional payouts, the longer the odds you select on your free play, the more of its real cash value you ultimately keep.
Free Play Strategy Guide
Converting free plays requires understanding the mathematics behind bonus play hedging:
Why Bet Underdogs with Free Plays
Since free plays don’t return your stake, you maximize value by choosing free play odds that maximize the promotional value, which is usually achieved by backing longer-priced underdogs.

Step-by-Step Free Play Conversion
1. Find Your Free Play Opportunity
Look for these common free play promotions:
- First Bet Refund: Get your stake back as a free play if you lose.
- Deposit Match: Receive free plays equal to your deposit.
- Weekly Bonuses: Regular free play rewards for active users.
- Refer-a-Friend: Free plays for both parties.
2. Choose Your Betting Markets
Best markets for free play conversion:
- Money Lines: Simple win/lose bets are easiest to hedge.
- Spreads: Work well but require exact opposite lines.
- Totals: Over/under bets with clear hedges.
- Avoid: Parlays, props, and complex bets.
3. Line Shopping is Critical
The closer your hedge line is to the free play line, the more return you keep. Always check multiple sportsbooks for the best hedge odds.
Common Free Play Mistakes to Avoid
- Betting favorites with free plays – Wastes 20-30% of value.
- Not hedging at all – Risks losing the entire bonus.
- Poor line shopping – Reduces return by 5-10%.
- Hedging at the same book – Often violates terms.
- Using free plays on parlays – Harder to hedge properly.
Advanced Free Play Strategies
Low-Hold Conversions
Find betting lines with minimal juice between books. For example:
- Book A: Team X +200 / Team Y -200.
- Book B: Team X +195 / Team Y -195.
This 5-cent difference creates a high-conversion opportunity.
Alternative Line Arbitrage
Some sportsbooks offer alternative lines that create better hedging opportunities. Always check alternate spreads and totals for optimal conversion rates.
What This Calculator Will Not Tell You
A free play calculator can show the mathematical value of a promotion, but it cannot account for every sportsbook rule or real-world situation involved in free play betting. First, many sportsbooks prohibit hedging both sides of the same market, and doing so may void the promotion, so always read the offer terms before placing your bets. Second, accounts that consistently convert promotional offers into cash are often limited or closed over time. This is common across the industry and should not come as a surprise. Finally, betting lines move. Your return is only locked in after both wagers have been placed and accepted at the quoted odds. If either line changes before you bet, your expected return may also change.
Frequently Asked Questions
What is a free play calculator?
A free play calculator is a betting tool that calculates the optimal hedge bet amount when you have a free play promotion. It shows you exactly how much to bet on the opposite side to lock in the same return whichever way the game goes, provided both wagers are accepted at the quoted odds.
How do I convert a free play to a locked in return?
To convert a free play to a locked in return: 1) Use your free play on an underdog with positive odds, 2) Calculate the optimal hedge amount using this calculator, 3) Place the hedge bet on the favorite at another sportsbook, 4) Receive the same return whichever way the game goes, once both wagers have been confirmed at the quoted odds. The higher the underdog odds, the more you can extract.
What percentage of a free play can I convert to cash?
You can typically convert 60-80% of a free play’s value into a locked in return. The exact percentage depends on the odds you choose – betting on bigger underdogs (+200 or higher) and finding close hedge lines maximizes your conversion rate. Our calculator shows the exact percentage for any bet combination.
Why bet underdogs with free plays?
Free plays don’t return your stake – only winnings. This makes underdog bets more valuable. A $100 free play at -110 returns $90.91 if it wins, but at +200 it returns $200. By hedging properly, you can convert more of the free play’s value into a locked in return when betting longer odds.
Is using a free play calculator legal?
Yes, using a free play calculator and hedging strategy is completely legal. You’re simply making strategic bets to lock in the same return whichever way the game goes from promotional offers. However, always check sportsbook terms – some prohibit hedging at the same book, which is why you should use different sportsbooks for your free play and hedge bet.
Is a freeplay the same as a free play?
Yes. Freeplay and free play describe the same type of sportsbook promotion. The spelling varies between operators, but the mechanic does not. If your promotion returns only the winnings and not the promotional stake, this calculator will work regardless of which spelling your sportsbook uses.
What conversion rate is a good result on a free play?
A conversion rate of more than 70% is generally considered a good result. As shown in the worked examples, longer odds usually produce higher conversion rates because more of the promotional value is retained after hedging. The calculator lets you compare different odds before placing your bets.
Can I hedge my free play at the same sportsbook?
Usually not. Many sportsbooks prohibit hedging both sides of the same market, and doing so may void the promotion. Always read the promotion’s terms before placing your bets. If hedging is permitted, remember that your return is only locked in once both wagers have been accepted at the quoted odds.
