What is MRR and how is it calculated?
MRR (Monthly Recurring Revenue) is calculated by multiplying your number of paying customers by the average revenue per user (ARPU). It's the most fundamental SaaS metric, showing your predictable monthly revenue stream.
What is a good LTV:CAC ratio?
A healthy LTV:CAC ratio is 3:1 or higher. This means for every dollar spent acquiring a customer, you earn at least three dollars over their lifetime. Below 3:1 suggests you're spending too much on acquisition; above 5:1 may mean you're underinvesting in growth.
What is a good monthly churn rate for SaaS?
For B2B SaaS, a good monthly churn rate is under 2%. For B2C or SMB-focused SaaS, under 5% is acceptable. Best-in-class companies achieve under 1% monthly churn, which means retaining customers for an average of 8+ years.
How much runway should a startup have?
Most experts recommend maintaining 12-18 months of runway. Under 6 months is critical and requires immediate action (fundraising, cost cuts, or revenue acceleration). Over 24 months gives comfortable room to experiment and pivot.
What is Net Revenue Retention (NRR)?
NRR measures revenue retained from existing customers including expansion (upsells) minus churn and contraction. An NRR above 100% means your existing customers are growing in value over time, even without new customers. Top SaaS companies achieve 120%+ NRR.
