Estimate delay cost
What this calculator covers
Free procurement delay cost calculator. Convert late approvals, late PO release or supplier delivery delays into a clear financial impact for management. It converts each day of late delivery into cost by combining daily manpower, equipment, penalty, overhead, and lost production exposure. The build-up matches the standard delay-cost categories used in EOT (extension of time) claims under FIDIC and NEC construction contracts.
When to use it
Use it when a late procurement action affects site progress, production continuity, installation sequence, project milestones, rental equipment, subcontractor availability, or contractual penalties.
How the logic works
The calculator multiplies the number of delay days by daily cost categories, then adds any fixed one-time cost. The result gives a practical estimate of the commercial impact of procurement delay.
Practical procurement example
Worked example: a fabrication package delivered 12 days late. Site has 8 crew idle at $60/hr x 8 hrs/day, $2,500/day equipment rental, $1,200/day site overhead, and no lost production. Delay cost = (8 x 60 x 8 x 12) + (2,500 x 12) + (1,200 x 12) = 46,080 + 30,000 + 14,400 = $90,480. The premium supplier who would have delivered on time was $8,000 more expensive at award - a $82,480 net loss from choosing the cheaper quote, before penalty clauses are counted.
What to watch out for
Do not use delay-cost numbers as legal claims without contract review. The tool is for decision support, escalation, and internal visibility, not automatic entitlement or penalty recovery.
How to read the delay cost result
The result shows the estimated commercial exposure created by the delay. It should be used to show scale, urgency, and management impact. If the daily cost is high, a faster but slightly more expensive procurement decision may be commercially better than waiting for a small price reduction.
Inputs to document before escalation
Keep evidence for manpower idle time, equipment rental, subcontractor standby, overhead, production loss, penalty exposure, and fixed costs. If the number will be used outside internal escalation, check whether the contract allows the cost category and whether notices, approvals, and records are complete.
Good practice before using the output
Use the result to support urgency and prioritization. It is especially useful when a delayed approval, delayed PO, or unresolved supplier issue is blocking other work. The number should be treated as an estimate until verified by project controls, finance, operations, or contract administration. Before sharing it outside the immediate team, confirm whether each cost category is real, avoid double counting, and separate recoverable contractual cost from internal business impact.
How to use this in real procurement work
Use this when a late approval, delayed PO, supplier slip, missing document, or payment hold threatens the plan. Enter delay days and the daily cost of site overhead, idle labour, equipment standby, production loss, or penalty exposure. The result helps procurement show why a faster action can be cheaper than waiting for a small discount.
In real life, use the number for escalation, not blame. Attach the calculation to an expediting request, approval reminder, recovery-cost comparison, or management note. If the delay is contractual, confirm notice requirements before using the figure externally.
Visual example: delay-to-cost path
Use this when slow approval is more expensive than a negotiated discount.
Delay cost assumptions to document
Procurement delay cost is not limited to the late item itself. A delayed purchase order, supplier delivery, inspection approval, or release payment can create idle manpower, standby equipment, missed installation windows, production interruption, liquidated damage exposure, and additional supervision cost. Use conservative numbers first so the result is credible, then run a realistic scenario if the impact needs escalation.
The output should support a decision, not replace project controls. If the cost impact is high, use it to justify urgent approval, partial shipment, alternate supplier review, air freight, or formal escalation with clear commercial reasoning.

Procurement Delay Cost Calculator FAQ
What counts as procurement delay?
Procurement delay includes any late action or event in the procurement chain that affects delivery, installation, commissioning, operations, or project completion. It can be caused by late material requisitions, unclear specifications, delayed technical approval, slow budget approval, late PO release, supplier manufacturing delays, missing documents, failed inspections, shipping problems, customs clearance issues, payment holds, or site access constraints. The cause should be recorded clearly because different causes have different owners. A supplier delay, internal approval delay, and client decision delay should not be treated as the same issue.
Why convert delay into cost?
Converting delay into cost helps decision makers understand that procurement delay is not only a schedule problem. A late PO or shipment can create idle labor, equipment standby, extended preliminaries, storage charges, air freight, expediting cost, liquidated damages exposure, lost production, missed revenue, or management escalation time. Showing the cost impact makes it easier to prioritize approvals, support urgent sourcing, negotiate recovery plans, or justify additional resources. It also helps procurement communicate delay in commercial language that finance and leadership can act on.
Can this be used for claims?
The calculator can support early claim analysis, internal discussion, and preparation of a delay narrative, but it is not a formal claims determination. A real claim must be checked against contract wording, notice requirements, programme logic, causation evidence, mitigation records, correspondence, approval history, and applicable law. Use the result to estimate possible exposure and organize the facts. Before sending a claim to a supplier, client, or contractor, the commercial, contract, and legal teams should review the calculation and supporting records.
