How Plus Odds Work
Understanding plus odds is actually straightforward once you break it down.
Formula:
Profit = (Odds ÷ 100) × Bet Amount
Example:
- Odds: +250
- Bet: $50
👉 Profit = (250 ÷ 100) × 50 = $125 profit
👉 Total payout = $125 (profit) + $50 (stake) = $175

| Odds | Bet Amount | Profit | Total Payout | Meaning |
|---|---|---|---|---|
| +100 | $100 | $100 | $200 | Even odds |
| +150 | $100 | $150 | $250 | Slight underdog |
| +300 | $100 | $300 | $400 | Clear underdog |
| +500 | $100 | $500 | $600 | Big underdog |
| +1000 | $100 | $1000 | $1100 | Major upset |
