Understanding the Calculator Results
Decimal Odds
Decimal odds represent the total amount returned, including your original stake.
Formula:
Decimal Odds = Total Return ÷ Stake
Example:
If you bet $20 and receive $50:
50 ÷ 20 = 2.50
Your decimal odds are 2.50.
Implied Probability
Implied probability shows the chance of an outcome according to the odds.
Formula:
Implied Probability = (1 ÷ Decimal Odds) × 100
Example:
Decimal odds:
2.00
Calculation:
(1 ÷ 2.00) × 100 = 50%
This means the bookmaker odds suggest a 50% probability.
Potential Profit
Potential profit represents the money you win excluding your original stake.
Formula:
Profit = Stake × (Decimal Odds – 1)
Example:
Stake:
$100
Decimal odds:
3.00
Calculation:
100 × (3 – 1)
= $200 profit
Total Return
Total return includes both your winnings and original stake.
Formula:
Total Return = Stake × Decimal Odds
Example:
$100 stake at 3.00 odds:
100 × 3
= $300 total return
Your profit is $200, and your original $100 stake is included.
Example: Using the Bookies Odds Calculator
Imagine you want to bet on a football match.
Your information:
- Odds format: Decimal
- Odds: 2.50
- Stake: $40
Step 1: Calculate Probability
Formula:
1 ÷ 2.50 × 100
= 40%
The implied probability is 40%.
Step 2: Calculate Profit
Formula:
40 × (2.50 – 1)
= $60
Your potential profit is $60.
Step 3: Calculate Total Return
Formula:
40 × 2.50
= $100
Your total payout would be $100, including your original $40 stake.

Tips for Using Betting Odds Calculations Effectively
Compare Odds From Multiple Bookmakers
Different bookmakers may offer different odds for the same event. Small differences can significantly affect long-term results.

Keep records of:
- Bets placed
- Stakes
- Profits
- Losses
- Betting strategy
This helps improve decision-making over time.
Avoid Focusing Only on High Odds
