Understand Cost of delay

One idea, three depths

Choose how deeply to explain Cost of delay

Cost of delay: Estimate foregone benefits and continuing team burn caused by delaying a project.

Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Cost of delay to answer this question: estimate foregone benefits and continuing team burn caused by delaying a project? Enter Expected monthly benefit after launch, Delay duration, Monthly team and holding cost during delay, and 1 other input; the calculator shows Estimated cost of delay. Try changing one number and watch what happens to Estimated cost of delay. The answer tells you Estimated cost of delay.

Age 15Explain it to a 15-year-oldConnect it to the formula

This makes schedule economics visible but depends on counterfactual assumptions. Use a range for benefits and avoid counting costs that would occur regardless of delay. The rule is Cost of delay = monthly benefit × delay months + monthly team burn × delay months + one-time loss. Its input values are Expected monthly benefit after launch, Delay duration (months), Monthly team and holding cost during delay, One-time opportunity loss, and the main result is Estimated cost of delay. Try changing one number and watch what happens to Estimated cost of delay.

CollegeExplain it at college levelState the model precisely

This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Cost of delay = monthly benefit × delay months + monthly team burn × delay months + one-time loss, evaluated from Expected monthly benefit after launch, Delay duration (months), Monthly team and holding cost during delay, One-time opportunity loss to produce Estimated cost of delay. This makes schedule economics visible but depends on counterfactual assumptions. Use a range for benefits and avoid counting costs that would occur regardless of delay. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.

The decision this tool supports

Estimate foregone benefits and continuing team burn caused by delaying a project.

Why the business model works

This makes schedule economics visible but depends on counterfactual assumptions. Use a range for benefits and avoid counting costs that would occur regardless of delay.

Inputs and operating assumptions

This model uses Expected monthly benefit after launch (at least 0), Delay duration (at least 0), Monthly team and holding cost during delay (at least 0), One-time opportunity loss (at least 0). Keep currencies, accounting treatment and time periods consistent with one another.

The formula

Cost of delay = monthly benefit × delay months + monthly team burn × delay months + one-time loss

What the calculator produces

The primary output is Estimated cost of delay; it also exposes Foregone benefit, Continuing delay-period cost, Cost per week of delay. Change one assumption at a time so the comparison remains explainable.

Before using the result in a decision

This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.

Frequently asked questions

What does the Cost of delay do?

Estimate foregone benefits and continuing team burn caused by delaying a project.

How does the Cost of delay work?

The calculator applies Cost of delay = monthly benefit × delay months + monthly team burn × delay months + one-time loss. This makes schedule economics visible but depends on counterfactual assumptions. Use a range for benefits and avoid counting costs that would occur regardless of delay.

What can I learn from the Cost of delay?

It connects company inputs to a transparent business result. Change one value at a time to compare operating scenarios.

Does MW SysArc receive or store what I enter?

No. The calculation runs locally in your browser. MW SysArc does not receive or store your calculation inputs.

How should I use the result?

Use the result as a practical reference. Review the inputs, assumptions and stated limitations before relying on it.
