SaaS Revenue Model by Niche: B2B, PLG, Vertical & Enterprise Benchmarks (2026)
Not all SaaS is the same. Model B2B SMB ($99 ARPU, 4% churn), PLG consumer ($15 ARPU, 7% churn), vertical niche SaaS, and enterprise sales-led with grounded benchmarks and 5-year ARR projections.
One SaaS Default Doesn't Fit All
A PLG consumer app at $15 ARPU and 7% monthly churn has completely different unit economics than vertical SaaS at $149 ARPU and 3% churn or enterprise at $599+ and 2% churn. Using generic "$49/mo, 5% churn" assumptions produces misleading ARR projections.
InnovexFlow ships niche SaaS benchmarks: B2B SMB, PLG Consumer, Vertical/Niche, Enterprise Sales-Led, and Marketplace/Platform — each with tier mix, CAC, churn, and traffic defaults sourced from OpenView and Bessemer medians.
Benchmark Comparison
| SaaS Type | Typical ARPU | Monthly Churn | CAC |
|---|---|---|---|
| PLG Consumer | $9–$25 | 6–10% | $25–$50 |
| B2B SMB | $49–$199 | 4–6% | $80–$200 |
| Vertical / Niche | $79–$399 | 2–4% | $150–$350 |
| Enterprise | $299–$1,500+ | 1–2% | $400–$2,000 |
| Marketplace | Take-rate + subs | 4–6% | $50–$120 |
Core SaaS Projection Formula
Our engine models 60 months of:
- Visitor growth → signup conversion → trial-to-paid
- Monthly churn on paid base
- Expansion revenue (% of MRR)
- Tier mix (monthly vs annual billing)
- CAC applied to new paid customers each month
Output: MRR, ARR, LTV:CAC, and profit by year. See also our LTV:CAC ratio guide and unit economics explainer.
How to Pick Your Niche Benchmark
- Who pays? Consumers → PLG. Teams → B2B SMB. Regulated industry → Vertical.
- How do they buy? Self-serve vs sales-led determines CAC and conversion rates.
- What's expansion? Seat-based? Usage-based? Model expansion % separately.
