How the Calculation Works

1. Decimal Odds Formula

Total Return = Stake × Decimal Odds
Profit = Total Return − Stake

---

2. Fractional Odds Formula

If odds are A/B:

Total Return = Stake × (A ÷ B) + Stake
Profit = Stake × (A ÷ B)

---

3. American Odds Formula

For positive odds (+150):
Profit = Stake × (Odds ÷ 100)

For negative odds (-150):
Profit = Stake × (100 ÷ Odds)

---

4. Implied Probability Formula

$P = \frac{1}{\text{Decimal Odds}} \times 100$P=Decimal Odds1​×100

This formula helps you understand the bookmaker’s estimated chance of winning.

Practical Example

Let’s say you place a bet:

• Stake: $100
• Decimal Odds: 2.50

Calculation:

Total Return = 100 × 2.50 = 250
Profit = 250 − 100 = 150

So, if your bet wins, you earn:

• Total return: $250
• Profit: $150

Now, implied probability:

$P = \frac{1}{2.50} \times 100 = 40\%$P=2.501​×100=40%

This means the bookmaker suggests a 40% chance of winning.
