American vs. Decimal Odds: Myths Debunked

Confused about American and decimal odds? Here's the quick breakdown:

  • American Odds use "+" and "–" symbols. A positive number (+150) shows profit on a $100 bet, while a negative number (–150) shows how much you need to bet to win $100.
  • Decimal Odds show total return per $1 wagered. For example, odds of 2.50 mean a $1 bet returns $2.50 (including your stake).

Key Facts:

  • Both formats give the same value, just displayed differently, though sportsbook vs. betting exchange odds can differ in overall profitability.
  • American odds are common in the U.S., while decimal odds are popular internationally.
  • You can easily convert between formats:
    • Example: +150 (American) = 2.50 (Decimal).
    • Example: –150 (American) = 1.67 (Decimal).

Quick Comparison Table:

Display Format +150 or -150 2.50 or 1.67

Decimal vs American Odds

American and Decimal Odds Basics

Let’s break down how these two odds formats work and how they calculate returns.

American Odds Explained

American odds show profit or required stakes based on a $100 base. They use plus (+) and minus (–) symbols:

  • Positive odds (+X) indicate how much profit you'd make on a $100 bet.
    Formula: Profit = (Stake × X) ÷ 100
  • Negative odds (–X) show how much you need to bet to make a $100 profit.
    Formula: Stake required = (Stake × 100) ÷ X

For example, if the odds are +200, a $50 bet would yield a $100 profit: (50 × 200) ÷ 100 = $100. If the odds are -200, you’d need to bet $200 to win $100: (200 × 100) ÷ 200 = $100.

Decimal Odds Explained

Decimal odds show the total return for every $1 you bet, including your original stake. The formula is straightforward:
Return = Stake × Odds

For instance, if the odds are 2.50 and you bet $10, your total return would be $25: 10 × 2.50 = $25. This includes your $10 stake and $15 profit.

Now that you know the basics, we can clear up common misconceptions about these formats.

4 Common Myths About Odds Types

Myth 1: Decimal Odds Are Always Better

Decimal odds show the total return on a bet but aren't necessarily superior. For example, placing a $100 bet at -150 (American odds) or 1.67 (decimal odds) will still result in a total return of $167.

Myth 2: American Odds Are Too Confusing

American odds might seem tricky at first, but they're straightforward once you break them down. A favorite listed at -150 means you need to bet $150 to win $100. On the other hand, an underdog at +150 will give you $150 in profit for a $100 bet.

If you're switching between formats, converting them is simple:

Myth 3: You Can't Compare Formats

You can easily convert odds between formats. Here's a quick reference:

American Odds Decimal Equivalent
+200 3.00
+150 2.50
-150 1.67
-200 1.50

Myth 4: Decimal Odds Aren't Used in the US

While decimal odds are more common internationally, they are available on many US betting platforms. They clearly display total payouts, making them a convenient option. You can choose the format that aligns best with your betting style.

In the next section, we'll compare these odds formats side by side for a deeper understanding.

Side-by-Side Format Comparison

American odds show the profit or stake relationship for a $100 bet. A positive number indicates the profit on a $100 wager, while a negative number tells you how much you need to bet to win $100. Decimal odds, on the other hand, represent the total return for every $1 wagered, making it easy to calculate your return with a simple formula: Bet × Odds.

Here’s a comparison of the two formats:

Quick Reference Chart

Feature American Odds Decimal Odds
Display Format -150 or +150 1.67 or 2.50
Total Return Calculation Varies for positive and negative odds Simple: Bet × Decimal
Profit Display Direct for $100 bets Requires subtracting the stake
Best Use Case Standard bet amounts Flexible bet sizes
Break-Even Point -100/+100 2.00
Implied Probability Needs conversion Easy: 1 ÷ Decimal

For example, if you bet $75:

  • With American odds of -150, the profit would be calculated as (75 ÷ 150) × 100 = $50.
  • With decimal odds of 1.67, the total return would be $75 × 1.67 = $125.25.

American odds are great for quickly understanding profit on round-number bets, while decimal odds work better for varying wager amounts. Up next, learn how these formats contribute to fair and clear betting on peer-to-peer platforms.
