1. What is Project Delay Cost (PDC)?

Project Delay Cost (PDC) is a metric that calculates the average daily cost impact of delays in a project. It helps quantify the financial impact of project delays by averaging the delay costs over the total project duration.

2. How Does the PDC Calculator Work?

The calculator uses the PDC formula:

Where:

• \( \sum(Delays) \) — Sum of all delay costs (in currency)
• \( Total\:Days \) — Total duration of the project (in days)

Explanation: The equation calculates the average daily cost impact of delays by dividing the total delay costs by the total project duration.

3. Importance of PDC Calculation

Details: Calculating PDC helps project managers understand the financial impact of delays, make informed decisions about schedule adjustments, and justify additional resources or budget when needed.

4. Using the Calculator

Tips: Enter daily delay costs as comma-separated values (e.g., "100,200,150" for three days of delays costing 100, 200, and 150 currency units respectively). Enter the total project duration in days.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for delay costs?
A: Use consistent currency units for all delay costs (e.g., all in dollars or all in euros).

Q2: Should I include zero values for days without delays?
A: No, only include actual delay costs. The calculator sums these values and divides by total project days.

Q3: How can I reduce PDC in my project?
A: Focus on critical path activities, improve risk management, allocate contingency reserves, and implement delay mitigation strategies.

Q4: Is PDC the same as liquidated damages?
A: No, PDC is a calculated metric while liquidated damages are predetermined penalties specified in contracts.

Q5: Can PDC be negative?
A: Typically no, since delay costs are usually positive values representing additional costs incurred.
