Sports Betting Money Line Calculator

A money line bet is a type of sports wager where you bet on which team will win the game, regardless of the point spread. This calculator helps you understand implied probability, convert moneyline odds, and estimate potential payouts.

What is a Money Line?

A money line bet shows the odds of each team winning the game outright. Positive numbers indicate how much you win per $100 bet, while negative numbers show how much you need to bet to win $100.

Example: If the money line for Team A is +200, you win $200 for every $100 wagered. If it's -250, you need to bet $250 to win $100.

Key Concepts

Money lines show the probability of each outcome
Positive numbers favor the team, negative numbers are against the team
Used in sports like football, basketball, and hockey

How to Use This Calculator

Enter the moneyline odds for a team and the amount you want to bet. The calculator will show you:

The implied probability of each outcome
The potential payout if your bet wins
A comparison of the odds

Implied Probability Formula:
For positive odds: Probability = 100 / (Odds + 100)
For negative odds: Probability = (Odds / (Odds - 100)) × 100

Formula Explained

The calculator uses these formulas to determine implied probability and potential payout:

Implied Probability:
For positive moneyline (e.g., +200):
Probability = 100 / (200 + 100) = 0.333 or 33.3%

For negative moneyline (e.g., -250):
Probability = (250 / (250 - 100)) × 100 = 0.833 or 83.3%

Potential Payout:
Payout = (Bet Amount × Odds) / 100
For positive odds: Payout = Bet Amount × (Odds / 100)
For negative odds: Payout = Bet Amount × (100 / |Odds|)

Worked Examples

Example 1: Positive Moneyline

Team A has a moneyline of +200. You bet $100.

Implied probability: 100 / (200 + 100) = 33.3%
Potential payout: $100 × (200 / 100) = $200

Example 2: Negative Moneyline

Team B has a moneyline of -250. You bet $250.

Implied probability: (250 / (250 - 100)) × 100 = 83.3%
Potential payout: $250 × (100 / 250) = $100

Moneyline	Implied Probability	Bet $100	Bet $200
+200	33.3%	$200	$400
-250	83.3%	$40	$80
+350	22.2%	$350	$700

Frequently Asked Questions

What does a positive moneyline mean?

A positive moneyline means you win more money than you bet. For example, +200 means you win $200 for every $100 wagered.

What does a negative moneyline mean?

A negative moneyline means you need to bet more money to win $100. For example, -250 means you need to bet $250 to win $100.

How do I convert moneyline odds to probability?

Use the formulas shown in the "Formula Explained" section. For positive odds, divide 100 by the odds plus 100. For negative odds, divide the odds by the odds minus 100.

What's the difference between moneyline and point spread?

Moneyline bets are on who will win the game outright, while point spread bets are on whether a team will cover the point spread. Moneyline odds reflect the probability of each team winning.
