How to Get Betting Odds: A Full Guide

How Common Betting Odds Work Explained
Decimal odds are the easiest type of number most the world looks at for betting. When you see numbers like 2.50, working out how much you might win is easy – just multiply your bet by the decimal. For instance, a $10 bet at 2.50 odds gives back $25 total (and that has your first bet in it).
US Style Fractional Odds
Fractional odds, shown as things like 5/1, tell you how much you could win as it relates to your bet. With 5/1 odds, for every $1 used, you might win $5, which is why they get used so much in the UK for horse betting. A $10 bet at 5/1 gives back $60 total ($50 winnings plus your $10 bet).
The US Odds Way
American odds are presented with a plus/minus way that looks at $100 bets: 여기서 안전성 확인하기
- Plus numbers (+150) mean the profit you might get with a $100 bet
- Minus numbers (-150) show how much you need to bet to get $100
Changing Odds Types
Knowing how betting numbers work together is key for making money. They all show the same possible win chance and possible returns, just in different ways. Serious betters often change from one type to another to find good chances in markets all over.
Being able to read these odds types helps move you from a simple bettor to someone who makes choices based on possible returns and likely outcomes with good sureness.
Knowing Decimal Odds in Sports Betting
What are Decimal Odds?
Decimal odds are the easiest way to figure out possible winnings in sports betting.
These numbers, shown as decimals like 2.50 or 1.75, act as straight multipliers for working out total payouts, including your first bet.
Working Out Possible Returns
To find your possible returns with decimal odds:
- Multiply your bet by the decimal odds
- Total return has your first bet
- Work out profit by taking out the first bet from total return
Example Calculation
With a $100 bet at odds of 2.50:
- Total return = $100 x 2.50 = $250
- Profit = $250 – $100 = $150 net gain
Knowing Chance and Value
Decimal numbers near 1.00 show likely outcomes:
- Odds of 1.20: Sure favorite
- Odds of 2.00: Even chance
- Odds of 5.00: Sure underdog
Why Decimal Odds are Good
Decimal odds have clear benefits:
- Understood all over
- Easy to look at across bookmakers
- Simple math with no need to change
- Used a lot in European betting markets
- Less mix-ups as seen with fractional or US odds
Knowing Fractional Odds in Sports Betting
Basics of Fractional Odds
Fractional odds show betting chances through simple ratios, often used by UK betting shops.
These odds look like 5/1 or 2/1, where the first number shows possible profit as it relates to the second number bet.
For instance, odds of 5/1 mean a $5 profit for every $1 bet, with the first bet given back when you win.
Getting Returns with Fractional Odds
To find possible returns, multiply your bet by the fraction shown.
With 7/2 odds, change the fraction to a decimal (7÷2=3.5) and multiply by your bet amount. A $20 bet at 7/2 odds returns:
- Profit: $70 (bet × 3.5)
- Total return: $90 (profit + first bet)
Knowing Favorites and Chance
When odds show smaller first numbers, like 1/4, they mean a big favorite in the bet world. This way needs a bigger bet for less profit – bet $4 to win $1.
To find chance from fractional odds:
- Add both numbers (bottom + top)
- Divide the bottom number by this sum
- Example: 1/4 odds = 4 ÷ (1+4) = 0.8 = 80% chance
These sums help bettors see risk levels and possible returns before they place bets.
Knowing US Odds: A Full Guide

Basics of US Odds
American odds, also called moneyline odds, use a unique way of plus (+) and minus (-) numbers to show betting chances.
This fixed way is the base for sports betting all through North America.
How US Odds Work
Plus odds (+150) talk about the possible profit on a $100 bet. When you see +150, a winning $100 bet makes $150 in profit.
On the other side, minus odds (-150) show the amount needed to win $100. With -150, bettors must risk $150 to make $100 in profit.
Knowing Favorites and Underdogs
The plus sign (+) means the underdog, while the minus sign (-) points to the favorite.
A bigger plus number means a bigger underdog, while a bigger minus number means a stronger favorite in the match.
Changing US Odds to Chance
Minus Odds Change
For minus odds, use this rule:
Chance = (minus odds) / (minus odds + 100) × 100
Example: -150 changes to 60% chance (150/250 × 100)
Plus Odds Change
For plus odds, work out:
Chance = 100 / (plus odds + 100) × 100
Example: +150 makes 40% chance (100/250 × 100)
Smart Betting Choices
Getting these chance changes lets bettors:
- See good bet chances
- Work out likely outcomes
- Make smart bet choices
- Look at odds across different sports places
