About the Delay Cost Calculator
Construction delays can be extremely costly, impacting everything from labor to financing.
This calculator quantifies the financial impact of delays.
This tool calculates the total cost of construction delays.
Formula
Total Delay Cost = Daily Delay Cost × Delay Days - TDC
- — Total Delay Cost
- DDC
- — Daily Delay Cost
- DD
- — Delay Days
Total Delay Cost = Daily Delay Cost × Delay Days.
Daily delay costs include labor, equipment, financing, and overhead.
How to use this calculator
- 1
Enter daily delay cost
The cost of one day of delay.
- 2
Enter delay days
The number of days the project is delayed.
Example calculations
Construction delay impact
Example 1A project is delayed 15 days with a daily delay cost of $5,000.
- Total delay cost:
- $75,000
- Weekly delay cost:
- $35,000
Interpreting your results
Delay costs can quickly escalate and impact project profitability.
Prevention is almost always cheaper than paying for delays.

- Cost studies: analyze delay cost drivers.
Common mistakes to avoid
-
Underestimating daily delay costs
Include all costs: labor, equipment, overhead, and lost revenue.
-
Ignoring ripple effects
Delays can cascade and impact other projects and contracts.
