cost-in-nok

CLI tool that analyzes a codebase and estimates development cost in NOK.

Install

npm install -g cost-in-nok

Or run directly without installing:

npx github:hiemil/cost-in-nok

Usage

Run in any project directory:

cost-in-nok

Options

-d, --dir <path>          Directory to analyze (default: ".")
--min-rate <number>       Minimum monthly rate in NOK (default: 120000)
--max-rate <number>       Maximum monthly rate in NOK (default: 180000)
--hours-per-loc <number>  Hours per line of code (default: 0.05)
--exclude <patterns>      Additional exclude patterns (comma-separated)

How it works

The tool scans your codebase, counts lines of code (excluding node_modules, vendor directories, config files, etc.), and estimates development time using a simple formula:

Hours = LOC × 0.05 × complexityMultiplier

This translates to 5 hours per 100 lines of code for a senior developer working without AI tools.

Why not COCOMO?

COCOMO II is an industry-standard estimation model from the 1980s. However, it overestimates modern web development by roughly 4x. It was calibrated for an era where developers wrote much more code themselves, before npm had 2 million packages and modern frameworks handled most boilerplate.

This tool uses a simpler model calibrated against real-world projects.

Complexity adjustment

• Simple code (low cyclomatic complexity): 20% faster
• Complex code (high cyclomatic complexity): 30% slower
