Calculate campaign ROI by script: ROAS, CPA, attribution views, LTV payback. "what's the ROI on this campaign".
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
# /digital-marketing-pro:roi-calculator
> **Script location.** If your host does not set `${CLAUDE_PLUGIN_ROOT}`, the scripts are in this plugin's `scripts/` folder, next to `skills/`. Run them with Python 3.10 or newer: `python`, or `python3` where `python` is not found (macOS, many Linux systems).
## Purpose
Campaign ROI calculator with multi-touch attribution models. Produces a comprehensive ROI analysis across channels for budget justification, optimization recommendations, and executive reporting.
## Input Required
The user must provide (or will be prompted for):
- **Campaign spend by channel**: Dollar amounts invested per channel (paid search, paid social, email, SEO, content, events, etc.)
- **Conversions and revenue by channel**: Number of conversions and total revenue attributed to each channel
- **Time period**: The date range for the analysis (week, month, quarter, year)
- **Attribution model preference**: Last-touch, first-touch, linear, time-decay, or position-based (or compare all models)
- **Customer LTV**: Optional -- average customer lifetime value for long-term ROI projection
- **Industry vertical**: For benchmark comparison context

How to install
mdr add indranilbanerjee/neels-plugins/roi-calculator@sha256:02d3d70682d95819The line at the top of this page pins the label git:20261011.1a0c374, 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.
