## How to Estimate a Project Timeline
Divide total effort by weekly available hours, then add a buffer for unknowns and scope changes.
### Formula
**Buffered Hours = Effort x (1 + Buffer %)**
**Weeks = Buffered Hours / Hours Per Week**
Divide total effort by weekly available hours, then add a buffer for unknowns and scope changes.
### Formula
**Buffered Hours = Effort x (1 + Buffer %)**
**Weeks = Buffered Hours / Hours Per Week**
Exemplo Resolvido
120-hour project, working 20 hours/week, with 20% buffer.
- Buffered hours = 120 x 1.20 = 144 hours
- Weeks needed = ceil(144 / 20) = 8 weeks
- Months = 8 / 4.33 = 1.8 months
