1. What is Available Man Hours?

Available man hours represent the total productive hours available from a workforce after accounting for planned absences. It's a crucial metric for project planning, resource allocation, and workforce management.

2. How Does the Calculator Work?

The calculator uses the Available Man Hours formula:

Where:

• \( \text{Total Employees} \) — Number of workers available
• \( \text{Hours per Day} \) — Working hours per employee per day
• \( \text{Days} \) — Number of working days in the period
• \( \text{Absences} \) — Total hours of planned absences

Explanation: The equation calculates total potential hours and subtracts known absences to determine actual available working hours.

3. Importance of Available Man Hours

Details: Accurate man hour calculation helps in project scheduling, cost estimation, and ensuring adequate staffing levels to meet deadlines.

4. Using the Calculator

Tips: Enter total number of employees, standard working hours per day, number of days in the period, and total planned absence hours.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between man hours and available man hours?
A: Man hours is the total potential hours, while available man hours subtracts absences and non-productive time.

Q2: How should I account for part-time workers?
A: Either count them as fractional employees (e.g., 0.5 for half-time) or adjust their hours per day accordingly.

Q3: What types of absences should be included?
A: Include planned vacations, holidays, training days, and other known time-off.

Q4: How precise should my inputs be?
A: For most purposes, rounding to nearest quarter-hour is sufficient, but adjust based on your needs.

Q5: Can this be used for overtime calculations?
A: This calculates available hours at standard capacity. Overtime would be additional hours beyond these.
