Player Prop betting (also known as player performance markets) has exploded in popularity, largely driven by the rise of “Bet Builders.” Instead of betting on who wins the match, you bet on individual battles: Will Haaland have over 1.5 shots on target? Will Rodri complete over 80 passes?
The problem is that most bettors just look at an average (“He averages 2.5 shots per game”) and guess. That is not enough. Our Player Props Calculator uses the Poisson Distribution adjusted by an Opponent Difficulty Modifier to give you the true mathematical probability of a player hitting their line.

How to Use the Player Props Calculator
This tool converts simple averages into actionable “Over/Under” probabilities. Here is your winning workflow:
- Choose Your Stat: Use the tabs to select the market: Shots, Shots on Target, Passes, Tackles, or Assists.
- Find the Average: Enter the player’s average stat per 90 minutes.
- Pro Tip: Use data from FBref or WhoScored. Ensure you check the player’s recent form (last 5 games) rather than just season averages.
- Adjust for the Matchup (Crucial): Use the Opponent Difficulty Slider.
- Is he playing against a weak defense that concedes many shots? Slide to the Right (+).
- Is he playing against Manchester City or a team that dominates possession? Slide to the Left (-) to reduce his expected output.
- Compare Odds: The calculator outputs the “Fair Odds.” If the calculator says the probability of “Over 0.5 Shots on Target” is 65% (1.54), and the bookie offers 1.75, you have found value.

Real-World Examples: Context is Key
The “Average” doesn’t tell the whole story. Here is how to use the adjustment slider to win.
Example 1: The Possession Trap (Passes Market)
You want to bet on a Center Back to have Over 60.5 Passes. He averages 65 passes per game.
- Scenario: His team is playing against a high-pressing team (like Liverpool or Arsenal).
- Adjustment: You calculate that he will have less time on the ball. You move the slider to -15% (Harder Opponent).
- Result: The calculator shows the probability of hitting 60+ passes drops significantly. You avoid a losing bet that looked good on paper.
Example 2: The Shooting Volume (Shots Market)
A winger averages 2.1 shots per game. The bookie sets the line at Over 2.5 Shots @ 2.20.
- Scenario: He is playing a bottom-table team that allows the most shots in the league.
- Adjustment: You move the slider to +20% (Easier Opponent).
- Result: The adjusted probability for Over 2.5 Shots rises to 55% (Fair Odds 1.82). Since the bookie offers 2.20, this is a massive value play.
Frequently Asked Questions (FAQ)
What counts as a “Tackle” in betting?
Most bookmakers use Opta data. A tackle is defined as when a player connects with the ball in a ground challenge where he successfully takes the ball away from the man in possession. Important: Interceptions (cutting a pass) do not count as tackles.
What happens if the player is substituted?
If the player starts the match, the bet stands, even if they are subbed off after 10 minutes (unless your specific bookie has a “Super Sub” offer). If the player does not play at all, the bet is void. If they come off the bench, rules vary—check if your bet applies to “Starters Only.”
Does “Shots” include “Shots on Target”?
Yes. The “Total Shots” market includes all attempts: shots on target, shots off target, and blocked shots. The “Shots on Target” market is stricter and only includes shots that go in or are saved by the keeper.
Where can I find Pass Completion stats?
Sites like FBref, WhoScored, and SofaScore provide detailed passing data. Look for “Passes Attempted” vs. “Passes Completed” depending on which market you are betting on (most bookies bet on Attempted Passes).
