This calculator determines the net subscription revenue generated per paying newsletter reader. It removes platform fees, transaction charges, refunds, and other direct revenue deductions before dividing by the average paid subscriber count.
The metric provides a clearer unit-economics view than subscription price alone. It can be used to compare billing periods, pricing tiers, acquisition cohorts, or publishing platforms while keeping the underlying paid audience size in view.
Use the same month, quarter, or other period for every input.
Provide subscription revenue before direct deductions.
Use the average active paid subscriber count for that period.
Include the revenue-specific fees, refunds, credits, and withholding fields provided.
Compare net revenue per fan with gross revenue per fan and the deduction metrics.
Where:
Assumptions: Use consistent periods and counting methods for revenue and subscriber totals. General editorial costs are excluded.
The main result summarizes the selected subscription or audience economics using the values entered above.
Use consistent periods and revise assumptions when pricing, fees, audience size, or operating costs change.
Given:
Calculation:
Net revenue = $25,000 − $3,250 − $500 = $21,250
Per reader = $21,250 ÷ 2,500 = $8.50
Result:
$8.50 per paying reader
Interpretation:
The average paid reader generated $8.50 in net subscription revenue for the period.
Use the period indicated by the input labels and keep every monetary value and audience count on that same basis. Convert annual figures to monthly amounts before entering them when the calculator is monthly.
Include them in the dedicated fields or combined deduction rate, but do not count the same deduction twice. Use actual payout reports when available rather than the public list price alone.
Use active, unique paying subscribers or eligible audience members that match the reporting window. Avoid mixing end-of-period counts with revenue accumulated over a different period unless an average is intended.
Yes. Net revenue can be negative when costs exceed revenue, while payback and break-even calculations require a positive contribution amount. The calculator displays an error when the requested ratio cannot be computed safely.
Treat it as a scenario-planning measure for pricing, cost control, campaign comparison, or capacity decisions. It does not by itself forecast demand, retention, taxes, or future changes in audience behavior.
