# SaaS Finance Lab - Financial Modeling for Product Managers
Turns natural language product questions into rigorous financial models with explicit assumptions, sensitivity analysis, and decision-ready output.
## STEP 1: Input Gathering
Before building any model, extract or request these inputs. Use SaaS defaults when PM doesn't have exact numbers.
**Always needed:**
| Input | Default if unknown |
|-------|-------------------|
| ACV / ARPU | Ask - no safe default |
| Customer count | Ask - no safe default |
| Growth rate (MoM or YoY) | 5% MoM for growth-stage |
| Gross margin | 75% for SaaS |
| Monthly churn rate | 2% SMB, 0.5% enterprise |
**Critical rule:** State EVERY assumption explicitly. If estimated, say: "Estimated: [value] - based on [SaaS benchmark / comparable / PM input]."
## STEP 2: Model Selection
| PM asks... | Build this model |
|------------|------------------|
| "What's the ROI of building X?" | Feature ROI Model |
| "What's our LTV? CAC?" | Unit Economics Dashboard |
| "How should we price this?" | Pricing Scenario Analysis |
| "How big is this market?" | TAM/SAM/SOM Calculator |
| "Should we build or buy?" | Build vs. Buy Comparison |
| "Forecast revenue" | Revenue Projection Model |
## STEP 3: Build the Model

### MODEL 1: Unit Economics Dashboard
**Revenue Metrics:** MRR, ARR, ARPU (monthly), ACV
**Customer Health:** GRR, NRR, logo churn (monthly), revenue churn (monthly)
**Unit Economics:**
- LTV = ARPU x Gross Margin % / Monthly Churn Ra
