What This Calculator Does
This SaaS pricing model calculator compares three common pricing strategies side by side: per-seat (user-based), usage-based (consumption), and flat fee (fixed monthly). It projects revenue for each model over 3 years factoring in customer growth, churn, seat expansion, and usage growth to help you identify which pricing model maximizes long-term revenue for your specific business.
The Formula
Each model has different growth dynamics. Per-seat revenue grows as customers add users (seat expansion). Usage-based revenue grows as customers increase consumption. Flat fee revenue only grows with new customer acquisition. The 3-year projection applies net customer growth (new customers minus churn) and model-specific revenue expansion rates to forecast annual recurring revenue for each approach.
Step-by-Step Example
Enter base metrics
100 current customers. 20% annual customer growth. 8% annual churn.
Configure per-seat model
5 avg seats per customer at $25/seat/month. 15% annual seat expansion.
Configure usage model
500 avg units per customer at $0.10/unit. 25% annual usage growth.
Compare results
Year 1: Per-Seat $150K, Usage $60K, Flat $119K. Year 3: Per-Seat $228K, Usage $146K, Flat $133K. Best 3-year model: Per-Seat.

Common Mistakes to Avoid
Choosing a pricing model based only on current revenue without projecting growth dynamics. Usage-based models often start lower but can scale faster with product adoption.
Ignoring churn impact on different models. Flat fee models are hit hardest by churn because there is no expansion revenue to offset losses.
Not considering customer perception. Per-seat pricing penalizes collaboration (adding users costs more), while usage-based rewards efficiency.
Assuming linear growth. Real SaaS growth compounds, and the difference between models becomes much more significant in years 2 and 3.
