Weeks Needed vs Total Effort (Hours)

Formula

Divide total effort by weekly available hours, then add a buffer for unknowns and scope changes.

Buffered Hours = Effort x (1 + Buffer %)

Weeks = Buffered Hours / Hours Per Week

120-hour project, working 20 hours/week, with 20% buffer.

How much buffer should I add?

10-20% for well-defined projects, 30-50% for projects with significant unknowns. Buffer absorbs scope creep, debugging, and unexpected delays.

Why use available hours instead of total work hours?

Not all work hours go to a single project. Account for meetings, email, admin, and other projects when estimating available time.

How do I estimate total effort hours?

Break the project into tasks, estimate each one, and sum them. Use past projects as benchmarks. When in doubt, triple your initial gut estimate.
