FAQ
How do you calculate SaaS metrics?
MRR = customers × average revenue per customer. ARR = MRR × 12. Churn = customers lost ÷ customers at the start of the month. LTV = ARPA ÷ monthly churn. CAC = sales and marketing spend ÷ new customers. Burn multiple = net burn ÷ net new ARR.
What is a good LTV to CAC ratio?
3:1 is the common benchmark. Below 1:1 you lose money on every customer; above 5:1 you are usually underspending on growth.
What growth rate does YC expect?
YC's stated benchmark during the batch is 5–7% weekly growth, with 10% described as exceptional. Roughly 22–33% month over month.
What is a burn multiple?
Net burn divided by net new ARR. Under 1 is excellent, 1–2 is good, and above 3 signals you are buying growth inefficiently.
