Usage-Tier Pricing

Inspect the usage and cost source files and identify the candidate metered units, then evaluate each against three tests: it grows with customer value, the customer can predict it, and it correlates with your cost to serve.

Choose one unit and define exactly what counts as consumption, including what is excluded, when the counter resets, and whether unused volume expires at the period boundary.

Place bracket boundaries at the gaps in the actual account distribution from the source files rather than at round numbers, so most accounts sit comfortably inside a bracket instead of hovering at an edge.

Price each bracket so the effective per-unit rate falls as volume rises, and display that declining rate explicitly, since the falling unit price is the reason a growing account stays rather than shopping around.

Build a usage estimator that takes one number the buyer already knows, maps it to a bracket, and shows the monthly figure, because unpredictable bills are the main objection to metered models.

Define the movement rules between brackets: how an account crosses upward mid-period, whether it is billed pro rata or at the next boundary, how it moves back down, and how the customer is warned before either happens.

Specify responsive behavior: on mobile, put the estimator first with the bracket table collapsed beneath and the resulting figure sticky at the bottom; on tablet, place the estimator above a horizontally scrollable bracket table; on desktop, show the estimator and full bracket ladder side by side with the buyer's current bracket highlighted as they adjust the input.
