Method and assumptions
The recommended price spreads fixed monthly costs across projected customers, adds variable and fixed payment costs, then solves for a price that preserves the target operating margin after percentage processing fees.
This is a unit-economics floor, not a substitute for value-based pricing or customer research. Taxes, refunds, churn, acquisition cost, annual discounts, and support complexity need separate modeling.

Common questions
What costs belong in fixed monthly costs?
Include costs that do not change directly with each customer, such as salaries, hosting minimums, software subscriptions, and baseline support.
What belongs in variable cost per customer?
Include usage-linked infrastructure, email, storage, third-party API usage, and other costs that grow with each account.
Should I charge exactly the recommended price?
Treat it as an economic floor. Your final price should also reflect customer value, positioning, willingness to pay, and the support burden of each segment.
