What are Decimal Odds?

Decimal odds (also called European odds or Australian odds) represent your total return for a $1 bet, including your stake. For example, odds of 3.50 mean you'll receive $3.50 back for every $1 wagered (including your original stake).

📊 How Decimal Odds Work

  • 3.50: Win $2.50 profit + $1 stake = $3.50 total
  • 4.00: Win $3 profit + $1 stake = $4.00 total
  • 1.50: Win $0.50 profit + $1 stake = $1.50 total

🔢 Conversion Formula

Fractional = (Decimal - 1) simplified

Example: 3.50 = (3.50 - 1) = 2.50 = 5/2

The "-1" removes your stake from the calculation.

🌍 Where They're Used

  • Europe (most countries)
  • Australia & New Zealand
  • Canada
  • Most online bookmakers

Common Conversions

Decimal Odds Fractional Odds Example ($10 Stake)
1.10 1/10 Win $1, Return $11
1.20 1/5 Win $2, Return $12
1.25 1/4 Win $2.50, Return $12.50
1.50 1/2 Win $5, Return $15
2.00 1/1 (Evens) Win $10, Return $20
3.00 2/1 Win $20, Return $30
3.50 5/2 Win $25, Return $35
4.00 3/1 Win $30, Return $40
5.00 4/1 Win $40, Return $50
11.00 10/1 Win $100, Return $110

Key Difference: Stake vs. Total Return

Decimal Odds (3.50)

Shows: Total Return

$10 stake × 3.50 = $35 total return

($25 profit + $10 stake back)

Fractional Odds (5/2)

Shows: Profit Only

$10 stake at 5/2 = $25 profit

(Plus $10 stake returned separately)
