When should I use NPV over a simple ROI calculation?

Use NPV for multi-year investments where the time value of money matters. ROI is generally sufficient for quick sanity checks or single-year projects.

What is included in the sensitivity analysis feature?

Sensitivity analysis models three scenarios—Base Case, Conservative, and Optimistic—by adjusting variables like discount rates and expected benefits to see how they impact the final NPV.

What financial metrics can this skill calculate?

This skill can calculate ROI (Return on Investment), NPV (Net Present Value), IRR (Internal Rate of Return), Payback Period, and TCO (Total Cost of Ownership).

How does the skill handle build-vs-buy decisions?

It provides a TCO comparison framework that evaluates CapEx, OpEx, opportunity costs, and hidden costs like maintenance and switching risks across both options.
