# How to Calculate Odds: A Comprehensive Guide

Are you someone who enjoys sports betting, but wants to learn how to calculate the odds of a particular event? If yes, then you have come to the right place. In this guide, we will walk you through everything you need to know about calculating odds, including the different types of odds, how to convert them, and more.

## Understanding the Basics of Odds

Let's start with the basics. Odds are a numerical expression that indicates the likelihood of an event occurring. In sports betting, they are used to determine the payout for a winning bet.

### Types of Odds

There are three main types of odds: American, fractional, and decimal.

 Type of Odds Format Example Payout American Plus or minus sign +150 or -150 \$150 for every \$100 bet or \$100 bet to win \$150 Fractional Fraction 2/1 \$2 for every \$1 bet Decimal Decimal 3.00 \$3.00 for every \$1 bet

## Calculating Probability from Odds

Now, let's discuss how to calculate probability from odds.

### Converting American Odds to Probability

To convert American odds to probability, you can use the following formula:

Probability = (Negative Odds) / ((Negative Odds) + 100)

For example, if the odds are -150, the calculation would be:

Probability = 150 / (150 + 100) = 0.6

This means that there is a 60% chance of the favorite winning the event.

To convert positive odds to probability, you can use the following formula:

Probability = 100 / (Positive Odds + 100)

For example, if the odds are +150, the calculation would be:

Probability = 100 / (150 + 100) = 0.4

This means that there is a 40% chance of the underdog winning the event LeoVegas.

### Converting Fractional Odds to Probability

To convert fractional odds to probability, you can use the following formula:

Probability = (Denominator) / (Denominator + Numerator)

For example, if the odds are 2/1, the calculation would be:

Probability = 1 / (2 + 1) = 0.3333

This means that there is a 33.33% chance of the event occurring.

### Converting Decimal Odds to Probability

To convert decimal odds to probability, you can use the following formula:

Probability = 1 / Decimal Odds

For example, if the odds are 3.00, the calculation would be:

Probability = 1 / 3.00 = 0.3333

This means that there is a 33.33% chance of the event occurring.

## Calculating Payouts from Odds

Now, let's talk about how to calculate payouts.

### Calculating Payouts from American Odds

To calculate payouts from American odds, you can use the following formulas:

### For negative odds:

Payout = (Stake / Negative Odds) * 100

For example, if you bet \$100 on odds of -150:

Payout = (100 / 150) * 100 = \$66.67

This means that your total payout would be \$166.67 (\$100 stake + \$66.67 profit).

### For positive odds:

Payout = (Positive Odds / 100) * Stake

For example, if you bet \$100 on odds of +150:

Payout = (150 / 100) * 100 = \$150

This means that your total payout would be \$250 (\$100 stake + \$150 profit).

### Calculating Payouts from Fractional Odds

To calculate payouts from fractional odds, you can use the following formula:

Payout = (Numerator / Denominator) * Stake

For example, if you bet \$100 on odds of 2/1:

Payout = (2 / 1) * 100 = \$200

This means that your total payout would be \$300 (\$100 stake + \$200 profit).

### Calculating Payouts from Decimal Odds

To calculate payouts from decimal odds, you can use the following formula:

Payout = Decimal Odds * Stake

For example, if you bet \$100 on odds of 3.00:

Payout = 3.00 * 100 = \$300

This means that your total payout would be \$400 (\$100 stake + \$300 profit).
