# Usage-Based vs Per-Seat MRR Calculator — Model the Revenue Impact | Enso

> Compare per-seat and usage-based pricing revenue models side by side. Enter your customer base, usage assumptions, and growth rate to calculate MRR, ARR, and 12-month revenue trajectories for each pricing approach.


The shift from per-seat to usage-based pricing changes your revenue model fundamentally — your best customers pay more, your lightest users pay less, and your MRR becomes a function of product adoption rather than headcount.

The calculator above lets you model both pricing approaches side by side for your current customer base. Enter your seat counts, usage assumptions, and monthly growth rate to see how MRR and ARR diverge over 12 months under each model.

**What to look for:** A large gap between per-seat and usage-based revenue in the early months indicates your current seat pricing may be leaving money on the table with power users. Convergence at high growth rates suggests usage pricing scales better as your customer base expands.
