Frequently Asked Questions
What is MRR and ARR?
MRR (Monthly Recurring Revenue) is your predictable monthly subscription income. ARR (Annual Recurring Revenue) is MRR multiplied by 12. These are the core metrics that define SaaS business health.
What is a good LTV:CAC ratio?
A 3:1 LTV:CAC ratio is considered healthy - you earn $3 for every $1 spent acquiring a customer. Below 2:1 means acquisition costs are too high. Above 5:1 may mean you are under-investing in growth.
What is CAC payback period?
CAC payback is how many months it takes to recover customer acquisition costs. Under 12 months is ideal for B2B SaaS. Under 6 months indicates very efficient acquisition.
What is the Rule of 40?
The Rule of 40 states that growth rate plus profit margin should exceed 40%. A company growing 30% with 15% profit margins scores 45%, passing the test. This balances growth against profitability.
What is a good churn rate for SaaS?
Monthly churn under 3% is excellent for B2B SaaS. 3-5% is acceptable. Above 5% requires immediate attention. For B2C, rates tend to be higher, with 5-7% considered acceptable.
What is the Quick Ratio?
Quick Ratio measures growth efficiency: (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR). A ratio above 4 indicates healthy growth. Below 1 means you are shrinking.
