Money Line to Odds Calculator

Sports betting odds can be presented in several formats, including money line, decimal, and fractional. This calculator helps you convert money line odds to decimal and fractional odds, making it easier to compare different betting options.

What is a Money Line?

A money line is a type of sports betting odds format that shows the potential payout for a bet on a team or player to win. It's called "money line" because it represents the amount of money you would win if you bet $100.

Key Points:

Positive money line means the team is favored to win
Negative money line means the team is underdog
Money line odds don't include the +100 or -100 implied probability

For example, if you see "+150" for a team, it means you would win $150 if you bet $100. If you see "-200", it means you would need to bet $200 to win $100.

How to Convert Money Line to Odds

Converting money line odds to decimal or fractional odds involves a simple mathematical process. Here's how it works:

Decimal Odds = (Money Line / 100) + 1

Fractional Odds = (Money Line / 100) + 1

For negative money lines:
Decimal Odds = (100 / |Money Line|) + 1
Fractional Odds = (100 / |Money Line|) + 1

For positive money lines (favorites), the decimal odds will be greater than 2.00. For negative money lines (underdogs), the decimal odds will be less than 2.00.

Example Conversion

If a team has a money line of +150:

Decimal Odds = (150 / 100) + 1 = 2.50
Fractional Odds = 5/2 (which is equivalent to 2.50)

Examples

Let's look at some examples to see how money line conversions work in practice.

Example 1: Positive Money Line

Team A has a money line of +120

Decimal Odds: (120 / 100) + 1 = 2.20
Fractional Odds: 11/5 (which is equivalent to 2.20)

This means Team A is favored to win, and a $100 bet would pay $120.

Example 2: Negative Money Line

Team B has a money line of -180

Decimal Odds: (100 / 180) + 1 ≈ 1.5556 (rounded to 1.56)
Fractional Odds: 5/6 (which is equivalent to 1.5556)

This means Team B is the underdog, and you would need to bet $180 to win $100.
