Growth & Marketing FAQs
How do I calculate MRR?
Sum this month's recurring revenue: e.g., 120 customers × $49 = $5,880 MRR. Track net-new separately from expansion, contraction, and churned revenue to see true growth.
What is a healthy LTV to CAC ratio?
3:1 or better — each customer returns at least three times their acquisition cost. Below 1:1 you lose money on every signup; above 5:1 you're likely under-investing in growth.
How does churn compound over a year?
Brutally: 5% monthly churn leaves only ~54% of customers after 12 months (0.95^12). Cutting churn from 5% to 3% keeps ~70% — the calculator shows the retention curve.
ROAS vs ROI — what's the difference?
ROAS measures gross revenue per ad dollar (4:1 = $4 back per $1 spent); ROI subtracts all costs including product and overhead. Profitable ROAS can still mean negative ROI — compute both.
