Overview
The COCOMO (Constructive Cost Model) is an algorithmic software cost estimation model developed by Barry Boehm. This tool provides a user-friendly interface to calculate:
- Development Time (in months)
- Effort Required (in person-months)
- Average Team Size (number of people)
The calculator supports all three COCOMO models with customizable coefficients and cost drivers.
✨ Features
- 🎨 Modern, Responsive UI - Split-panel design with real-time results
- 📊 Three COCOMO Models - Organic, Semi-Detached, and Embedded
- ⚙️ Customizable Coefficients - Override default values for a, b, c, and d
- 💡 Cost Drivers Support - Single multiplier for Semi-Detached, multiple drivers for Embedded
- 📈 Real-time Calculations - Instant results via REST API integration
- 🎯 Visual Feedback - Color-coded modes and intuitive result cards
- 📱 Fully Responsive - Works seamlessly on desktop, tablet, and mobile devices
Tech Stack
- Frontend Framework: React 19.1.1

Usage
Basic Estimation
Enter KLOC (Thousand Lines of Code)
- Example: For 10,000 lines of code, enter
10
Select Project Mode:
- Organic 🟢 - Small teams, familiar environment (2-50 KLOC)
- Semi-Detached 🟡 - Medium teams, mixed experience (50-300 KLOC)
- Embedded 🔴 - Large teams, complex constraints (>300 KLOC)
Click "Calculate Results" to see:
- Development time in months
- Effort required in person-months
- Average team size
Advanced Options
Custom Coefficients: You can override the default COCOMO coefficients:
- a - Effort equation constant
- b - Effort equation exponent
- c - Time equation constant
- d - Time equation exponent
Cost Drivers:
- Semi-Detached Mode: Single effort multiplier (e.g., 1.2)
- Embedded Mode: Multiple key-value cost driver pairs
Example Calculation
Input:
- KLOC: 10
- Mode: Organic
- Default coefficients
Output:
- Development Time: ~6 months
- Effort: ~30 person-months
- Team Size: ~5 people
System Requirements
Before you begin, ensure you have the following installed in any of the systems(Linux/Windows/Mac OS):
