Usage Pricing Floors and Base Fees

Set a pricing floor for usage models and decide when a base fee is required to cover fixed costs.

Quick checklist

  • Separate fixed overhead from variable unit cost.
  • Model p50 and p90 usage to stress-test unit pricing.
  • Add a base fee when fixed cost is meaningful.
  • Use tiers to keep pricing predictable at scale.

Step-by-step

  1. Compute all-in unit cost: variable cost + fixed cost per unit.
  2. Set a margin target and solve for the unit price floor.
  3. Stress-test p90 usage to ensure margins hold at scale.
  4. Add a base fee if low-usage customers underpay.
  5. Use tiers to control bill shock and revenue volatility.

Signals that you need a base fee

  • Fixed overhead >20% of total cost at p50 usage.
  • Unit price looks uncompetitive without a minimum.
  • Usage is highly volatile month to month.

Common mistakes

  • Pricing only on variable cost and ignoring fixed overhead.
  • Using a unit customers cannot estimate.
  • Skipping tiers and exposing users to bill shock.
  • Setting a free tier without modeling paid unit volume.
