PRACTICAL GUIDE
Choose a billing unit customers can understand, then model how the bill and your execution costs move as usage changes. Cost math establishes a floor and exposure; it cannot tell you what a buyer will pay.

Count the full attempted workflow: model calls, tool calls, compute, and human review if it is part of delivery. Failed attempts can still cost money. Add other monthly cost per customer separately.
For action cost C, other monthly cost H, and usage n, modeled cost is C × n + H. This is an included-cost view, not net profit: taxes, payment fees, sales, fixed overhead, refunds and other costs are excluded unless you add them.
Revenue stays at S while usage changes. It gives the customer a predictable bill and puts the variable-usage risk on you. An unlimited plan is used below for arithmetic only, not as a recommendation.
Revenue is A × n. Define the billable unit clearly: attempted action or successful outcome. If failed runs cost money, include them in your cost basis even when they are not billed.
Revenue is S + O × max(0, n − Q), where Q is the included allowance and O the overage price. State how retries, failures, and partial work count.
Suppose one attempted action costs €0.30 and other monthly cost per customer is €5. These are illustrative inputs, not observed provider rates or a validated offer.
At 60 actions, cost is €0.30 × 60 + €5 = €23.
At 120 actions, the same €49 fixed plan costs €41 and leaves a 16.3% margin. The three plans trade off bill predictability, usage alignment and exposure to heavy use. Buyer research is still needed to decide whether any price or allowance is acceptable.
If each action consumes k credits, a balance of B credits buys floor(B/k) whole actions. Leftover credits do not buy a fraction of an action. Changing the number of credits per action changes the displayed unit; it does not improve the underlying margin.
For target margin m, a cost-based marginal revenue floor per credit is C / ((1 − m) × k). A subscription’s nominal value per credit, S/B, is a separate display and must not replace the plan revenue model. See the credit allowance worked example.
A useful export has one attempted customer action per row with full-attempt cost and success/failure status. The calculator reports mean, median, failure rate and nearest-rank p95 attempt cost. With fewer than 100 attempts, p95 is unstable. Attempt-cost p95 is not p95 cost per successful outcome because unpaired failures cannot be assigned to successful runs.
More observations improve your estimate of observed costs. They do not establish willingness to pay.
Enter component totals or import your own CSV, set light, typical and heavy monthly usage, then compare the contribution and margin for each plan. Usage weights must add to 100% for the blended view. Export a report or explicitly copy a link that contains only numerical assumptions.
