How to Use the Project Delay Calculator
Enter the original project deadline and how many days the project is delayed. Choose whether to count calendar days or business days. The calculator shows the new delivery date and how many additional days the project has slipped.
How to Minimize Delay Impact
- Communicate the delay to stakeholders immediately and transparently.
- Set the new deadline with enough buffer to account for further risks.
- Analyze the root cause and document corrective actions.
- Reallocate resources to critical-path tasks to recover time where possible.
Frequently Asked Questions
Does the business day calculator account for holidays?
This calculator excludes Saturdays and Sundays only. Public holidays vary by country and are not included. If the project period includes major holidays, add those days manually to the delay count.
Can I use this for contract penalty calculations?
Yes. Use the calendar-day or business-day result as your delay count, then multiply by the penalty rate specified in your contract (e.g., 0.1% of contract value per day) to estimate the penalty amount.
