What is a Project Time Calculator?

A project time calculator estimates total duration and cost based on team size, hours per day, and contingency buffers. Helps set realistic timelines and budgets before committing.

Formula

Total Hours = Estimated Hours x (1 + Buffer%)
Duration (days) = Total Hours / (Team x Hours/Day)
Total Cost = Total Hours x Hourly Rate
Weeks = Duration / Working Days per Week

Examples

US — 240 hours, 3 people, 6hrs/day, $75/hr, 20% buffer, 5-day week

Duration: 15 days | 3 weeks | Total hours: 288 | Cost with buffer: $21,600

UK — 160 hours, 2 developers, £80/hr, 15% buffer

Duration: 16 days | ~3.5 weeks | Cost: £14,720

Example — Canada

240 hours, 2 devs at C$90/hr, 20% contingency buffer. Buffered hours: 288 | Duration: 7.2 weeks | Dev cost: C$25,920 | With PM 15%: C$29,808

Why Use This?

Accurate estimation prevents scope creep, missed deadlines, and budget overruns — the three most common causes of project failure.

How much buffer?▼

10-15% for well-defined projects. 20-30% for unclear requirements. 30-50% for R&D or novel work.

Effort vs Duration?▼

Effort = total person-hours. Duration = calendar time. More people reduces duration but not always total effort (Brooks Law).

Why do projects take longer?▼

Optimism bias, scope creep, underestimating dependencies. The PERT technique uses: (Optimistic + 4×Likely + Pessimistic) / 6.

💡 Tip: Studies show software projects take 2x the initially estimated time on average. Build in at least a 25-30% buffer.
