SaaS pricing model choice dramatically affects revenue trajectory. Per-seat pricing provides predictability; usage-based pricing scales with customer value delivery. This calculator compares both models, finds the crossover point, and shows monthly and annual revenue projections.

How to Use the SaaS Pricing Calculator
SaaS pricing strategy determines not just revenue but customer acquisition cost, churn rates, and expansion revenue potential. This calculator helps you model both major pricing approaches.
Step 1: Model Per-Seat Pricing
Enter the number of paying users, monthly price per seat, the size of your free tier, and your freemium-to-paid conversion rate. The calculator shows MRR from direct paying users plus the incremental revenue from freemium conversions. Industry freemium benchmarks: 1–3% for consumer tools, 5–15% for B2B productivity tools with strong product-led growth.
Step 2: Model Usage-Based Pricing
Enter the average units consumed per customer per month (API calls, emails, storage GB, etc.), your price per unit, number of customers on the usage plan, and monthly usage growth rate. Usage-based models often start small but compound quickly as customers grow — a 10% monthly usage growth rate doubles consumption in about 7 months.
Step 3: Compare 12-Month Projections
The projection table shows how both models evolve over 12 months. Per-seat revenue is stable and predictable; usage-based revenue starts lower but accelerates if customers grow their usage. Look for the crossover point where usage-based revenue surpasses per-seat revenue — this shows which model dominates at scale.
Hybrid Model Strategy
Most mature SaaS companies use hybrid pricing: a base fee that covers included usage, with overage charges above the threshold. For example, $50/seat/month includes 10,000 API calls, then $0.005 per additional call. This provides revenue predictability from the base fee while capturing expansion revenue as customers scale. The base fee typically needs to cover COGS at minimum usage levels to maintain positive unit economics.
FAQ

What are the main SaaS pricing models?
The two dominant models are per-seat (user-based) pricing and usage-based pricing. Per-seat charges a fixed monthly fee per user — predictable and scalable with team size. Usage-based charges based on API calls, data volume, transactions, or other consumption metrics — aligns cost with value but creates revenue volatility. Hybrid models combine a base seat fee with usage overages.
What is a freemium conversion rate?
Freemium conversion rate is the percentage of free users who convert to paid plans. Industry benchmarks range from 1%–5% for consumer SaaS to 5%–25% for B2B SaaS with strong free-to-paid funnel design. A 2% freemium conversion rate on 10,000 free users = 200 paying customers.
Which SaaS pricing model generates more revenue?
It depends on usage patterns. Per-seat pricing wins when users are consistent power users who would consume high volumes if you charged by usage. Usage-based pricing wins when customers have highly variable usage and you want revenue to scale directly with value delivered. Most modern SaaS companies ($1B+ ARR) use hybrid models — a base fee that covers minimum usage, plus overages for high-volume customers.
