PERT Task Duration Estimator – Project Time Estimation Calculator

⏱️ PERT Task Duration Estimator

Calculate accurate task durations using the Program Evaluation and Review Technique (PERT). Input your optimistic, most likely, and pessimistic estimates to get realistic project timelines.

📊 How PERT Works

PERT uses three time estimates to calculate a weighted average that accounts for uncertainty:

Expected Time = (Optimistic + 4 × Most Likely + Pessimistic) ÷ 6

This formula gives more weight to the most likely scenario while considering best and worst-case scenarios.

🔵 Most Likely Estimate
Realistic scenario – normal conditions with typical challenges

Project Risk Impact Estimator - Risk Assessment & Mitigation Planning Tool

⚠️ Project Risk Impact Estimator

Quantify and prioritize project risks by calculating their probability and potential impact on time and cost. Make data-driven decisions for effective risk mitigation.

📊 Risk Assessment Methodology

Risk impact is calculated using probability and impact assessments:

Risk Score = Probability × Impact Value

Higher scores indicate risks requiring immediate attention and mitigation planning.

🎯 Probability Assessment

How likely is this risk to occur during the project?

Very Unlikely (0%) Uncertain (50%) Very Likely (100%)
50%
Uncertain
⏱️ Time Impact

How much additional time would this risk add if it occurs?

days
💰 Cost Impact

What additional cost would this risk create if it occurs?
