How much buffer should I price in for heavy users?
Need to size a pricing buffer for heavy users? Underprice and every heavy user erodes your margin; overprice and you lose the sale. This page helps teams with flat pricing find the number that covers AI costs and still leaves the margin you want.

Why this isn't trivial
The part people underestimate: a minority of heavy users can consume most AI cost, so pricing to the average leaves you exposed to the tail. In practice the biggest savings come from building the heavy-user tail into the price or capping it, so it is worth modelling before you commit.
How it's calculated
We estimate this by modeling heavy-user cost versus average and sizing a buffer so blended margin holds. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
How big is the heavy-user tail?+
Often a small share of users drives most cost; model it explicitly.
Buffer or cap?+
A buffer keeps pricing simple; a cap limits worst-case exposure — many use both.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
