How Do You Calculate Money Line

Money line odds are a common way to represent the probability of an outcome in sports betting. Unlike point spreads, money lines show the relative value of each team without any handicap. This guide explains how to calculate money line odds, interpret them, and use our calculator to make quick conversions.

What is Money Line?

A money line is a type of sports betting odds that shows the relative value of each team without any handicap. Unlike point spreads, money lines simply indicate which team is favored and by how much. A positive money line means the team is favored, while a negative money line means the team is underdog.

How to Calculate Money Line

Calculating money line odds involves understanding the implied probability and the payout structure. Here's a step-by-step guide to calculating money line odds:

Determine the implied probability for each team
Convert the money line to a decimal odds format
Calculate the payout for a $100 bet on each team
Compare the payouts to understand the value of each bet

Our calculator automates these steps, making it easy to quickly convert between money line odds and other formats.

Implied Probability Formula

For a positive money line (favored team):

Implied Probability = 100 / (Money Line + 100)

For a negative money line (underdog team):

Implied Probability = 100 / (100 - Money Line)

Money Line Formula

The money line formula is used to convert between different odds formats. Here's how it works:

Money Line Conversion

To convert from decimal odds to money line:

If decimal odds > 2.00: Money Line = (Decimal Odds - 1) × 100

If decimal odds < 2.00: Money Line = -100 / (Decimal Odds - 1)

This formula allows you to quickly convert between money line odds and other common betting formats.

Example Calculation

Let's look at an example to see how money line odds work in practice.

Team	Money Line	Implied Probability	Payout for $100
Team A (Favored)	+200	33.33%	$300
Team B (Underdog)	-300	25.00%	$100

In this example, Team A is favored with a +200 money line, meaning you win $200 for every $100 bet. Team B is the underdog with a -300 money line, meaning you need to bet $300 to win $100.
