# ROI Calculator
## Overview
An ROI calculator turns "this seems valuable" into "this pays for itself in 4 months." It is the most powerful document in enterprise sales because it translates product capabilities into financial outcomes that economic buyers can approve.
## When to Use
- "Build an ROI calculator"
- "Create a business case"
- "Calculate the ROI for [prospect]"
- "Quantify our value"
- "Build a TCO comparison"
## Step-by-Step Process
### Phase 1: Identify Value Drivers
What measurable outcomes does your product deliver? Time saved, revenue increased, costs reduced, risk mitigated. Map each to a financial metric.
### Phase 2: Build Scenario Models
- Conservative (what most customers achieve)
- Moderate (what typical customers achieve)
- Aggressive (what best customers achieve)
### Phase 3: Calculate
For each scenario: cost of current state, cost of your solution, net benefit, payback period, 1-year ROI, 3-year ROI.
### Phase 4: Assumption Documentation
Every input must be documented with its source. "Customer survey data" > "Industry average" > "Our estimate." The more defensible the assumptions, the more credible the business case.

3. **One-size output** — different stak
