Measure what share of your active readers became new paying members during one campaign or measurement window. The calculator also translates a target rate into a member goal and shows the recurring revenue represented by the observed conversions.
Use the same time window and audience definition for both counts.
Use the main result as a planning estimate tied to the assumptions entered. Compare scenarios with the same definitions and period rather than treating the output as a guaranteed outcome.
This calculator is an operational estimate. It does not include taxes or costs you do not enter.
If 250 of 10,000 reachable people subscribe, conversion is 2.50%. A 3% target equals 300 members, so the gap is 50. At $10 each, current monthly recurring revenue is $2,500.
Count active readers who had a realistic chance to see the paid offer during the selected period.
Only count them if the measured campaign specifically converted them during the same window.
The inputs use incompatible definitions or periods; align them before calculating.
No. It measures acquisition conversion, while churn should be evaluated separately.
A partial member is not possible, so the calculator rounds the required count up to the next whole person.
| Input | Use |

| Reachable audience | People who realistically received the offer |
| New paid members | Conversions from the same window |
| Target rate | Your own planning target, not an assumed benchmark |
