Three steps for operators. One primary calculator each.
01
Anchor the recurring base
Before you argue about growth rate, know this month's recurring revenue. MRR is the floor the rest of the model stands on.
Open MRR calculator →02
Time the acquisition payback
Spend on customers only makes sense if you recover CAC from contribution in a window your cash can survive. Run payback before you scale spend.
Open CAC payback calculator →03
Check if the book still grows
Net revenue retention shows whether expansion offsets churn. A growing logo count can still hide a shrinking revenue base.

Decision lanes
Pick the job you have. Each lane is a short set of tools, not the whole catalog again.
Recurring revenue
Monthly and annual subscription base, plus revenue per account.
Acquire and pay back
What it costs to win a customer, how long payback takes, and what that customer is worth.
Retain and expand
Logo and revenue loss, retention rate, and whether expansion repairs the book.
Margins and break-even
Gross and contribution margins, EBITDA, and the volume that covers fixed cost.
Price and cash plan
Pricing levers and near-term cash so growth plans do not starve the bank account.

Gotchas before you scale spend
Short warnings with a calculator handoff.
CAC without payback is incomplete
A low CAC looks fine until contribution takes a year to recover it. Time the payback before you raise spend.
CAC payback →Logo churn and revenue churn diverge
Losing small accounts can look mild in logos while dollars fall hard, or the reverse. Measure both before you celebrate retention.
Revenue churn →NRR can hide logo loss
Expansion from remaining accounts can lift NRR while customer count shrinks. Pair NRR with logo churn.
NRR →Gross margin is not contribution
Gross margin ignores variable selling cost. Contribution margin is what actually funds fixed overhead and payback math.
Contribution margin →Related hubs
