Software Development Cost Calculator Formula Explained
The calculator uses several formulas to estimate the total software project cost.
1. Base Development Cost Formula
The basic development cost is calculated as:
Base Development Cost = Development Hours × Developer Hourly Rate × Number of Developers
Example:
Development hours = 2,000 hours
Developer rate = $75/hour
Number of developers = 3
Calculation:
2,000 × 75 × 3 = $450,000
The base development cost is:
$450,000
2. Complexity Adjusted Cost Formula
Different software types require different levels of complexity. Advanced projects generally require more planning, testing, security, and expertise.
Formula:
Complexity Adjusted Cost = Base Development Cost × Complexity Factor
Example:
Base cost = $450,000
Business software factor = 1.5
Calculation:
450,000 × 1.5 = $675,000
The complexity-adjusted cost becomes:
$675,000
3. Maintenance Cost Formula
After software development, ongoing maintenance expenses must be considered.
Formula:
Maintenance Cost = Complexity Adjusted Cost × Maintenance Percentage ÷ 100
Example:
Complexity-adjusted cost = $675,000
Maintenance percentage = 15%
Calculation:
675,000 × 15 ÷ 100 = $101,250
Estimated maintenance cost:
$101,250
4. Total Estimated Cost Formula
The final project estimate combines development and maintenance expenses.
Formula:
Total Estimated Cost = Complexity Adjusted Cost + Maintenance Cost
Example:
Complexity-adjusted cost = $675,000
Maintenance cost = $101,250
Total:
675,000 + 101,250 = $776,250
Estimated total cost:
$776,250
5. Development Time Formula
The calculator estimates project duration based on team capacity.
Formula:
Monthly Working Hours = Number of Developers × 160 Hours
Development Time = Total Development Hours ÷ Monthly Working Hours
Example:
Development hours = 2,000
Developers = 3
Monthly capacity:
3 × 160 = 480 hours
Development time:
2,000 ÷ 480 = 4.16 months
Estimated duration:
Approximately 4.2 months
Software Development Cost Example
Suppose a company wants to build business management software.
Project details:
- Software type: Business Software
- Development hours: 3,000 hours
- Developer rate: $80/hour
- Developers: 4
- Maintenance: 15%
Step 1: Calculate Base Cost
3,000 × 80 × 4
= $960,000
Step 2: Apply Complexity Factor
Business software factor = 1.5
960,000 × 1.5
= $1,440,000
Step 3: Calculate Maintenance
1,440,000 × 15%
= $216,000
Step 4: Total Estimated Cost
1,440,000 + 216,000
= $1,656,000
Estimated software investment:
$1.65 million
