Cyclomatic Complexity Calculator

Calculate McCabe cyclomatic complexity from decision-point counts (if, else if, case, &&, ||, catch, ternary, loops) with risk-band guidance.

Frequently Asked Questions

Why does each && add complexity?

Because short-circuit logical operators introduce a hidden branch: the right side runs only if the left side resolves a particular way. Each is an independent path.

Should I always refactor at CC > 10?

Use it as a signal, not a rule. A switch over 20 enum cases may have CC of 21 but be very simple to read. CC catches dense conditional logic best.

What is cognitive complexity?

A metric by SonarSource that adds extra weight to nested constructs, recursion, and break/continue. It correlates better with how hard code is to understand.
