The Problem Nobody Talks About
You’re staring at a betting slip. Minus 110. Plus 180. Decimal odds. Fractional nonsense. Your brain feels like it’s been hit by a fastball. Most people give up right here. They don’t understand the language, so they either guess wildly or walk away entirely. Huge mistake.
Here’s the deal: understanding baseball odds isn’t rocket science. It’s just that nobody explains it properly.
American Odds: The Favourite and the Underdog
American odds work with two numbers. Negative and positive. That’s it.
The negative number (like -110 or -150) tells you how much you need to bet to win £100. If you see -110, you stake £110 to profit £100. Simple maths. The bigger the negative, the stronger the favourite. -200 means they’re heavily favoured. Your profit is smaller because the risk is theoretically lower.
The positive number (like +150 or +200) flips everything. This shows how much you win if you bet £100. Plus 150 means a £100 stake returns £150 profit. These are underdogs. Higher risk, higher potential reward. The bigger the plus sign, the less likely the bookies think they’ll win.
Decimal Odds: The European Way
Decimal odds are cleaner. Honestly, they should be everywhere.
1.95 means for every quid you stake, you get £1.95 back total (including your original stake). So a £100 bet at 1.95 returns £195. Your profit is £95. Low numbers mean favourites. High numbers mean underdogs. Dead simple.
Fractional Odds: The Confusing Bit
You might see 1/2 or 5/1 at certain sportsbooks. These are fractional odds, more common in the UK for traditional betting.
The first number is your profit. The second is your stake. So 3/1 means you profit £3 for every £1 wagered. A £10 bet at 3/1 nets you £30 profit plus your £10 back. That’s £40 total return.
Converting Between Formats Because Life Isn’t Fair
American to decimal: Take the American number, divide by 100, add 1. So -110 becomes 1.909 roughly. For positives, divide by 100 and add 1 as well. Plus 150 becomes 2.50.
Decimal to fractional: Subtract 1 from the decimal. So 2.50 minus 1 equals 1.50. That’s 3/2 in fractional form.
Why This Matters for Your Bets
Odds reflect probability but also bookmaker margin. A -110 favourite doesn’t mean exactly 52.38% implied probability. Close, though. Understanding this gap between what odds imply and what actually happens separates winners from donkeys.

Right. Next time you see plus or minus signs staring back at you, stop panicking and just multiply. The math works.
