Project Requirements
Project: Office renovation
Total Hours Needed: 400 hours
Available Workers: 5 people
Hourly Rate: $25/hour
Man Hours Calculation
Formula: Man Hours = People × Hours per Person
Hours per Person: 400 ÷ 5 = 80 hours each
Duration: 80 hours = 10 business days (2 weeks)
Total Cost: 400 hours × $25 = $10,000
Cost per Person: $10,000 ÷ 5 = $2,000 each

Understanding Man Hours Calculation
What are Man Hours?
Man hours (also called person hours or labor hours) represent the total amount of work performed by a team, calculated by multiplying the number of people by the hours each person works. This metric is essential for project planning, budgeting, and resource allocation.
Why Calculate Man Hours?
- •Project timeline estimation
- •Budget planning and cost control
- •Resource allocation optimization
- •Team size determination
Calculation Formulas
Basic Formula:
Man Hours = People × Hours per Person
Cost Formula:
Total Cost = Man Hours × Hourly Rate
Reverse Formula:
Hours per Person = Total Hours ÷ People
