Formula

Cyclomatic (est.) = Functions * Avg Nesting Depth
  • Code Complexity Estimator calculates its result from Lines of Code (LOC), Number of Functions, Average Nesting Depth, Comment Lines. It uses the formula Cyclomatic (est.) = Functions * Avg Nesting Depth. Change any input to recalculate the result instantly.
  • The main inputs are Lines of Code, Number of Functions, Average Nesting Depth, Comment Lines. Enter them in the units and format shown in the calculator.
  • Keep comparable quantities in compatible units whenever the formula combines or compares them.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Code Complexity

Inputs
  • Lines of Code: 5000 LOC
  • Number of Functions: 80
  • Average Nesting Depth: 3
  • Comment Lines: 500

Using Lines of Code (LOC) = 5000, Number of Functions = 80, Average Nesting Depth = 3, Comment Lines = 500, the calculated result is 240.

Sample result: Calculating…
