How it works
Calculate cost capacity
Plan price, marginal unit cost and the allowed cost share set the maximum economically supported usage.
Set warnings and grace
The result gives a primary allowance, an 80% warning and a temporary grace ceiling.
Frequently asked questions
What if there is no real usage data yet?
Use a conservative scenario and label it as an assumption. Recalculate after the first representative cohort completes a billing period.
Should the limit equal the highest observed usage?
Not automatically. Compare customer behavior with the cost the plan can support, then decide whether high usage belongs in another tier.
What happens at the limit?
Prefer a visible warning, clear upgrade path and reasonable grace behavior. A hard stop may be appropriate for genuine cost or abuse risk, but it should not surprise customers.
Does this calculate the right subscription price?
No. It tests whether a proposed allowance fits a given plan price and marginal cost.
