Cyclomatic Complexity Calculator: Measure Code Quality & Maintainability

Calculate Your Code's Cyclomatic Complexity

Total connections between nodes in your control flow graph.
Total statements or decision points in your control flow graph.
Typically 1 for a single program/function. Adjust if your graph has multiple exit points.

Unlock insights into your code's complexity with our Cyclomatic Complexity Calculator. Understand the number of independent paths in a program's source code, crucial for identifying areas needing refactoring and improving test coverage. This tool helps developers write more maintainable and less error-prone software.

Formula:

The most common formula for Cyclomatic Complexity (M) is:

M = E - N + 2P

  • E: The number of edges in the control flow graph.
  • N: The number of nodes in the control flow graph.
  • P: The number of connected components (e.g., exit points, usually 1 for a single program or function).
