You received a $100 “Free Bet” or “Bonus Bet” from a sportsbook. That sounds like free money, but there is a catch: Stake Not Returned (SNR).
Unlike a regular cash bet, if you win a Free Bet, you only get the profit—you don’t get the $100 stake back. This changes the math completely. If you use a standard hedging calculator, you will calculate the wrong amounts and lose money.
Our Bonus Bet Calculator is built specifically for this SNR logic. It helps you “wash” or convert your bonus into guaranteed cash by hedging across 2 outcomes (like Tennis/NFL) or 3 outcomes (like Soccer), regardless of the result.
Bonus Bet Calculator
SNR / DutchingHow to Use the Calculator
The goal of this tool is to tell you exactly how much cash to bet on the opposing side(s) to lock in a profit equal to a percentage of your free bet value.
- Select Market Type:
- 2-Way (Hedge): Use this for sports with no draw (e.g., Tennis, Basketball, Baseball, or “Draw No Bet” markets).
- 3-Way (1X2): Use this for sports like Soccer (Home / Draw / Away) where you need to cover two opposing outcomes with cash.
- Input Bonus Details:
- Enter the Bonus Amount (e.g., $100).
- Enter the Back Odds (The odds you are betting on with your Free Bet). Tip: Higher odds usually yield a better conversion rate.
- Input Hedge Details:
- Enter the Opponent Odds available at a different sportsbook.
- Check the Results:
- Cash Outlay: How much of your own money you need to bet on the hedge.
- Conversion Rate: The percentage of the free bet you will keep as profit (e.g., 75%).
Real-World Examples: Maximizing Retention
The “Golden Rule” of Free Bets is: Bet on longshots (high odds) with the bonus, and favorites (low odds) with cash. Here is why.
Example 1: The Optimized 2-Way Hedge (75% Retention)
You have a $100 Free Bet. You find an NFL underdog priced at 4.00 (+300).
- Bonus Bet: $100 on Underdog at 4.00. (Potential Return: $300 profit only).
- Hedge Bet: You find the Favorite at another bookie at odds of 1.30 (-333).
- The Math: The calculator tells you to bet $230.77 on the Favorite.
- Result: No matter who wins, you walk away with $69.23 in pure profit. This is a ~70% conversion rate.
Example 2: The Poor Strategy (Low Odds)
You use your $100 Free Bet on a favorite at 1.50 (-200).
- Bonus Bet: $100 on Favorite at 1.50. (Potential Return: $50 profit).
- Hedge Bet: The opponent is priced at 2.80 (+180).
- The Result: The math restricts you to a conversion rate of only ~30%. You turn a $100 bonus into just $30. Always aim for higher odds with SNR bets!
Example 3: 3-Way Dutching (Soccer)
You want to use a Free Bet on a soccer “Home Win” at odds of 5.00.
- The Hedge: You must cover “Draw” and “Away Win” with cash at other bookies.
- The Calculator: By inputting the odds for Draw (3.50) and Away (1.90), the calculator splits your cash stakes perfectly across those two outcomes to ensure the same profit regardless of the final score.
Frequently Asked Questions (FAQ)
What does “Stake Not Returned” (SNR) mean?
SNR means that if your bet wins, the bookmaker keeps the initial bet amount and only pays you the winnings. For example, a winning $10 cash bet at 3.00 odds pays $30 total ($20 profit + $10 stake). A winning $10 SNR Free Bet at 3.00 odds pays only $20 total.
What is a good conversion rate for a Bonus Bet?
Generally, retaining 70% to 80% of the free bet value is considered excellent (e.g., turning a $100 free bet into $75 cash). Anything below 60% is considered sub-optimal. To achieve high retention, you must bet on higher odds (typically 4.00 / +300 or higher).
Can I use this for “Risk-Free” bets?
Not directly. “Risk-Free Bets” (or “Second Chance Bets”) usually refund you in site credit only if you lose. That requires a different calculation strategy known as “SR (Stake Returned)” or a specific Risk-Free Bet Calculator. This tool is strictly for Free Bets you already have in your account.
