This answers “what does this feature cost me, spread over the subscribers in each tier?” You create one unit economic per tier. Every one uses the same cost, the feature’s total, and divides it by that tier’s subscriber count. Time: 10 minutes per tier.
Each tier carries the whole cost of the feature, so the figures do not add up to the feature cost and are not a split of it. Read each one as the feature cost per subscriber if that tier alone paid for it, and compare it with the tier’s price.

​
Before you start

  • A node for the feature. See Cost per feature.
  • A subscriber count for each tier, as one metric per tier, for example active_subscriptions_pro and active_subscriptions_enterprise. The Active Subscriptions by Tier template is a good starting point. See Business metrics.

​
Create a unit economic for each tier

Under Measure, select Unit Economics, then New unit economic. Repeat for each tier:
  • Name: Search cost per Pro subscriber
  • Cost from: the model and the feature node, the same node for every tier
  • Divide by: Published metric, then that tier’s subscriber count
  • More details: set Currency and a Unit Display Name of per Pro subscriber
Check the Preview shows a value, then select Create.

​
Read the result

  • Compare the tiers side by side on the Unit Economics page, or put them on a dashboard.
  • Set a goal on each, for example keeping the cost of Search per Pro subscriber below a share of the Pro price.
  • Because the cost is the same in every unit economic, differences between tiers come only from subscriber numbers. A rising figure for one tier means that tier is shrinking or the feature is getting more expensive. Check the feature’s cost trend to tell which.

​
Check your numbers

  • Each tier’s subscriber count must cover the same period as the cost, or the Preview shows no value.
  • For a single figure across every tier, create one more unit economic with the same cost divided by total subscribers.
