AI Implementation ROI Calculator
Gather inputs about current operations and produce a comprehensive roi-analysis.md with data-backed financial insights and a clear recommendation.
Contents
references/inputs.md — required and optional inputs, with defaults
references/methodology.md — all calculation formulas and sensitivity/comparison logic
references/output-template.md — full roi-analysis.md structure to fill in
Collect inputs. Gather every required cost, time, and labor input. If any required input is missing, ask for it in one organized message grouped by category. Do not guess. See references/inputs.md for the full input list and defaults.
Apply defaults. For optional parameters the user omits, use the conservative defaults in references/inputs.md and note that defaults were applied.
Calculate metrics. Compute time savings, cost savings, net monthly savings, ramp-up adjustment, payback period, 12-month ROI, NPV, and productivity gain using the formulas in references/methodology.md.
Run sensitivity and comparison scenarios. Produce conservative/base/optimistic cases and at least three comparison scenarios per references/methodology.md.
Generate the report. Write roi-analysis.md to the current working directory following references/output-template.md. Apply the formatting and calculation rules in references/rules-and-protocol.md.
Verify and summarize. Run the quality checklist in references/rules-and-protocol.md, then report the top 3 findings and the saved file path.
