A moderately complex application, such as an enterprise application with web and mobile functionality or a customer-facing service application, will range from \$80,000 to \$150,000.

## How do you calculate man months for a project?

HOW IS IT CALCULATED? The estimated human effort by work package in Part B can be calculated as follows (indicative method): if 1 year = 220 (working) days, then 1 month = 220/12 = 18.33 (working) days. So 24 full working days for one person would be 24/18.33 = 1.31 person‑months.

## What can I use instead of man hours?

## How do you estimate time required for a software development project?

A project’s duration = overall task time estimation (E) + E*risk buffer + E*time eaters. So, if a project’s overall task time estimation is 7,200 hours, the total project duration will be: 7,200 + 7,200*0.25 + 7,200*0.20 = 10,440 hours.

## How is Manhour calculated?

Multiply the number of workers by the number of hours each one worked to calculate the number of man-hours your business used during that time period. In this example, multiply 10 workers by 160 hours per worker to get 1,600 man-hours. This means that you produced 50,000 pieces using 1,600 man-hours.
