What is clv in betting?

Closing Line Value (CLV) in betting is a measure used by sports bettors to assess the value of the odds they’ve wagered on compared to the odds at the time the event starts, known as the closing odds. It’s a way to evaluate the skill in bet selection. A positive CLV indicates that a bettor got better odds than those available at the game’s start, suggesting a higher value bet. In essence, consistently beating the closing odds can be a sign of long-term betting success and skill.

Professional bettors diligently track, calculate, and discuss closing line value (CLV). It’s a telling indicator of a bettor’s expertise.

#1 Closing Line Value Calculator: Two Way (decimal odds)

Example 1: Baseball Betting (Red Sox vs. Yankees)

  • Taken Odds: You bet on the Red Sox at 2.06.
  • Closing Odds: At game time, the odds were 1.95 for the Red Sox and 1.93 for the Yankees.
  • Calculation: The script first calculates the bookmaker’s margin from the closing odds. It then computes the fair closing odds for both teams, considering this margin. Finally, the CLV is calculated as the percentage difference between your taken odds and the fair closing odds for the Red Sox.

Example 2: Basketball Betting (Lakers vs. Celtics)

  • Taken Odds: You bet on the Lakers at +7 with odds of 1.95.
  • Closing Odds: When the game starts, the odds are 1.80 for the Lakers at +7 and 2.1 for the Celtics at -7.
  • Calculation: Similarly, the margin is derived from the closing odds. The script calculates fair closing odds for the Lakers and Celtics. The CLV is then determined by comparing your taken odds for the Lakers to their fair closing odds.
