Current active members

Your current paying members or subscribers.

Why it matters: Defines the base you are defending-every churn or acquisition percentage references this starting point.

Average revenue per member / month (USD)

Why it matters: ARPU/ARPPU determines how much every retained customer contributes to MRR, so small tweaks create large deltas.

New members per month

Average new signups you expect each month.

Why it matters: Rolls in CAC, campaigns, and referrals-if this dips, you immediately feel it in net growth.

Monthly churn (%)

Percent of members who cancel each month.

Why it matters: Retention is the most compounding lever; reducing churn lowers the acquisition treadmill.

Months to simulate

Why it matters: Defines how long the math compounds before we summarize totals, helping you compare quarters vs. years.
