# ROI Calculator

This skill helps you calculate and communicate the return on investment for influencer marketing campaigns using various methodologies appropriate for your goals and available data.

> **Cross-discipline (paid ads):** this is the shared **return-math engine** for paid ads, [paid-measurement-loop](../../../ad/scale/paid-measurement-loop/SKILL.md), [attribution-reconciler](../../../ad/scale/attribution-reconciler/SKILL.md), and budget-optimizer delegate ROAS/CPA/payback ratios here rather than recomputing them. Save paid runs under `memory/ad/roi-calculator/`.

## Quick Start

Shortest invocation:

```
Calculate ROI for our influencer campaign: $25K spend, $72K revenue, 2.1M reach
```

Common scenario, compare methods before reporting:

```
What's the ROI of our campaign using direct revenue, EMV, and LTV-based methods?
```
