1. What is Moneyline Betting?

Moneyline betting is the simplest form of sports wagering where you pick which team will win the game outright. The odds are presented as either positive or negative numbers indicating the potential payout.

2. How Does the Calculator Work?

The calculator converts moneyline odds to implied probability using these formulas:

\[ \text{Positive Odds } (+): Prob = \frac{100}{Moneyline + 100} \] \[ \text{Negative Odds } (-): Prob = \frac{|Moneyline|}{|Moneyline| + 100} \]

Where:

Explanation: Positive odds show how much profit you'd make on a $100 bet, while negative odds show how much you need to bet to win $100.

3. Understanding Implied Probability

Details: Implied probability represents the breakeven point for the bet. If your assessment of a team's chance to win is higher than the implied probability, it may be a good bet.

4. Using the Calculator

Tips: Enter the moneyline odds as a positive or negative number (e.g., +250 or -150). The calculator will show the implied probability as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What does +200 moneyline mean?
A: +200 means a $100 bet would win $200 (total return $300). The implied probability is 100/(200+100) = 33.33%.

Q2: What does -150 moneyline mean?
A: -150 means you need to bet $150 to win $100 (total return $250). The implied probability is 150/(150+100) = 60%.

Q3: How is this useful for NBA betting?
A: Comparing implied probability to your own assessment helps identify value bets where the odds may be favorable.

Q4: What's the difference between American and decimal odds?
A: American odds use +/- format while decimal odds show total return per unit bet. +200 = 3.00 in decimal odds.

Q5: Should I always bet on negative moneyline favorites?
A: Not necessarily. While favorites win more often, the odds may not always provide good value relative to their actual win probability.
