How to Read Betting Odds Like a Pro

Learn the Three Main Betting Odds Formats
American Odds
American odds show plus and minus signs to tell you what you can win. If you see +150, a $100 bet gives you $150 in profit. If you see -150, you must bet $150 to win $100. This style is big in North American betting and shows clear favorites and underdogs.
Decimal Odds
Decimal odds show your total return with your first bet included. For example, odds of 2.50 mean a $100 bet gives back $250 in total ($150 profit and your $100 bet). Markets in Europe and Australia often use this simple format. 여기서 안전성 확인하기
Fractional Odds
Fractional odds like 5/1 show what you could win against your bet. A $100 bet at 5/1 brings back $500 in profit and your first bet. This old style is still used in UK horse racing and other places.
Changing Between Odds Formats
From Decimal to American
For decimal odds over 2.0, multiply by 100 to get American odds. For odds under 2.0, use the formula: -(100/(decimal-1)) to get negative American odds.
From Fractional to Decimal
To change fractional odds to decimal, divide the top number by the bottom and add 1. For example, 5/1 turns into (5÷1) + 1 = 6.0 in decimals.
Finding Good Bets
Smart bettors look at odds across styles to find good bets and odd market values. Knowing how to change formats shows true odds and good spots to bet.
All About American Odds
Basics of American Odds
American odds use plus and minus numbers to tell you profits on a $100 bet. Seeing +150 means you win $150 on a $100 bet. With -150, you need $150 to get a $100 profit.
Calculating Odds for Different Bets
For +150 odds, a $40 bet makes $60 (40/100 × 150 = 60). For -150 odds, to win $40, bet $60 (40/100 × 150 = 60).
Getting the Odds and Favorites Right
American odds are clues in sports betting:
- Negative numbers mean favorites likely to win
- Positive numbers show underdogs
- Bigger numbers mean clearer odds
- -300 is a stronger favorite than -150
- +300 shows a bigger underdog than +150

Getting Decimal Odds Right in Sports Betting
What are Decimal Odds?
Decimal odds, or European odds, show total possible payout per bet unit. These odds show as simple decimals like 2.50 or 1.80, displaying cleanly how much a successful bet will return, including the original bet.
How to Figure Out Payouts with Decimals
Decimal odds calculations are simple: multiply your bet by the decimal to find the total return. For example:
- Bet: $100
- Decimal odds: 2.50
- Total return: $100 x 2.50 = $250
- Profit: $150 ($250 minus original $100)
Knowing the Odds and Value
The decimal number is tied directly to the chance of the event:
- Lower decimals (1.20-1.50): Mean sure favorites
- Medium decimals (2.00-3.00): Point to even matches
- Higher decimals (4.00+): Signal underdogs
Understanding Fractional Odds in Sports Betting

What’s Up with Traditional British Betting?
Fractional odds show how you can profit in sports betting, mainly in British markets. These odds look like ratios, such as 5/1 or 2/7, showing how much you might win against your bet.
How to Find Potential Profits
With odds like 5/1, you get $5 for every $1 bet, plus get back your first bet. The method is simple:
- Profit = (Bet × Top Number) ÷ Bottom Number
- Total Return = Profit + Original Bet
