Calculate comprehensive ROI for AI implementation projects. Takes current costs, manual process time, team size, and hourly rates. Generates detailed roi-analysis.md with executive summary, cost-benefit tables, sensitivity analysis, break-even timeline, and comparison scenarios. Use when evaluating AI investments, building business cases, or justifying automation spend.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 - `references/rules-and-protocol.md` — calculation rules, interaction protocol, quality checklist ## Workflow 1. 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. 2. Apply defaults. For optional parameters the user omits, use the conservative defaults in `references/inputs.md` and note that defaults were applied. 3. 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`. …

How to install
mdr add onewave-ai/claude-skills/roi-calculator@sha256:88ba249198c28e0dThe line at the top of this page pins the label git:20260608.d82d20f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
