SaaS Revenue Model

Subscription-based MRR/ARR model with new customer acquisition, expansion revenue (upsell/cross-sell), and churn tracking. Build separate cohort sheets for each customer acquisition vintage.

Revenue Drivers

  • New MRR from new customers (volume x ACV)
  • Expansion MRR from existing customers (NRR - 1.0 component)
  • Gross churn MRR (churned logo count x average ACV)
  • Net new ARR bridge month-by-month

COGS Structure

  • Cloud infrastructure and hosting (AWS/GCP/Azure)
  • Customer success and onboarding labor
  • Third-party API costs (per usage)
  • Payment processing fees

Unit Economics to Model

  • Customer Acquisition Cost (CAC) by channel
  • CAC Payback Period (months to recover CAC at gross margin)
  • Lifetime Value (LTV) at cohort gross margin
  • LTV:CAC ratio target (3:1 minimum for Series A)
  • Gross Revenue Retention and Net Revenue Retention

Key Model Assumptions

Growth stage models require GAAP financial statements as the foundation. All projections must reconcile to audited financials. Quality-of-earnings adjustments should be clearly documented with investor-friendly presentation.

  • Monthly new logo adds and churn assumption toggle
  • Expansion revenue rate as % of ARR base
  • Sales productivity ramp (months to full quota)
  • Average ACV by customer segment

Funding Scenarios

Include IPO, strategic acquisition, and secondary scenarios with implied multiples based on comparable company trading and transaction comps.
