Betting on the “Total” (Over/Under) is one of the most popular ways to wager on sports, second only to the Point Spread. Whether you are betting on the total points in an NFL game or the run line in MLB, knowing your potential payout is essential.
However, knowing your payout isn’t enough. You also need to know your Implied Probability—the percentage chance the sportsbook thinks you have of winning based on the odds. Our Over/Under Payout Calculator does both instantly, helping you make smarter decisions on every total you play.

How to Use the Over/Under Calculator
This tool is designed for speed. It allows you to quickly check the math on a Total bet before you lock it in.
- Select Your Position: Toggle between Betting Over or Betting Under.
- Note: This is primarily for your reference to track which side you are analyzing.
- Enter Wager Amount: Input the amount of money you intend to bet.
- Enter Odds: Input the price offered by the sportsbook.
- Most standard totals are priced at -110 (US) or 1.91 (Decimal).
- If you are betting an “Alternative Total” (e.g., buying points), the odds might change to -130 or +100.
- Review the Data:
- Net Profit: What you will pocket if you win (excluding your stake).
- Implied Win %: The “Break-Even” percentage. If you don’t win at least this often, this bet is mathematically unprofitable in the long run.
Related Tools: If you want to calculate the “Fair Odds” by removing the sportsbook’s fee, use our No-Vig Calculator. To combine multiple Over/Under bets into one ticket, use the Parlay Calculator.
Real-World Examples: Understanding the Math
Why does the calculator show a probability higher than 50% for a standard bet? Let’s look at the numbers.
Example 1: The Standard NFL Total (-110)
You bet $110 on the Over 47.5 at standard -110 odds.
- Total Payout: $210.00.
- Net Profit: $100.00.
- Implied Probability: 52.4%.
- Insight: Even though an Over/Under feels like a coin flip (50/50), the “Vig” (fee) means you must be right 52.4% of the time just to break even.
Example 2: The Alternative Line (+100)
You choose an “Alternative Total,” taking a slightly harder line to get +100 (Even Money) odds. You bet $100.
- Total Payout: $200.00.
- Net Profit: $100.00.
- Implied Probability: 50.0%.
- Insight: By finding Even Money odds, your break-even point drops to a true 50%.
Frequently Asked Questions (FAQ)
What happens if the score lands exactly on the Total?
This is called a “Push.” If the Over/Under is set at a whole number (e.g., 47.0) and the final score is exactly 47, your bet is refunded. No money is lost or won. Most bookmakers use half-points (e.g., 47.5) to prevent this from happening.
What does Implied Probability mean?
Implied probability is the conversion of odds into a percentage. It represents how often you need to win that specific bet to break even. If your personal confidence in the bet is higher than the implied probability, it is a “Value Bet.”
Does overtime count for Over/Under bets?
Yes. In the vast majority of sports (NFL, NBA, MLB), overtime scores count toward the full game Total. The major exception is Soccer (Football), where totals are usually graded after 90 minutes plus injury time (excluding Extra Time/Penalties).
