Newsletter ROI Calculator

The calculator models a single email's revenue and multiplies it by 52 to represent a weekly newsletter cadence, which is a common publishing rhythm. If your actual send frequency is different — say, twice a month or daily — scale the multiplier accordingly rather than relying on the 52 figure as written.

It multiplies revenue per subscriber per send by 52 weeks and then by 1.5, which models an assumed 18-month average subscriber lifetime before they unsubscribe or stop engaging. That retention window is a general assumption rather than a figure pulled from your specific list's actual churn behavior.

Not directly — the underlying subscriber count is treated as fixed across the annual projection, and only the Subscriber LTV figure builds in an assumed retention period. A list with high churn will underperform this projection more than one with a loyal, long-tenured subscriber base.

No — it's gross revenue attributable to conversions from a single send, with no subtraction for the cost of acquiring those subscribers, the email platform's subscription fee, or the time spent producing the content. Treat it as a top-line revenue estimate to compare against those costs separately, not a net profit figure.
