What are good Early stage metrics?

Early stage (under $1M ARR) benchmarks: monthly churn 3% (strong: 1.5%), NRR 88% (strong: 100%), gross margin 70% (strong: 80%), CAC payback 15 months (strong: 9). Before $1M ARR, investors weigh retention and payback over scale. The example's runway is 20.7 months, with LTV:CAC of 2.9:1.

ARPU = MRR ÷ customers; gross profit per customer g = ARPU × gross margin; annual churn = 1 − (1 − c)^12; NRR = ((1 − c) × (1 + e))^12; GRR = (1 − c)^12; simple LTV = g ÷ c; LTV = Σ g × q^t for t = 0 … H − 1, q = (1 − c)(1 + e) ÷ (1 + d)^(1/12); CAC = sales and marketing ÷ new customers; payback = CAC ÷ g; LTV:CAC = LTV ÷ CAC; cash(t+1) = cash(t) + MRR(t) × margin − sales and marketing − other costs; runway = months until cash < 0

Worked example

A seed-stage SaaS on $25,000 MRR from 125 customers at $200 a month, adding 10 a month on $18,000 of sales and marketing, with 3% monthly churn, 2% monthly expansion, 72% gross margin, $55,000 of other monthly costs and $900,000 raised and unspent.

  1. 1ARPU: $25,000 ÷ 125 = $200; gross profit $144 a month at 72%
  2. 2Retention: 3% churn and 2% expansion a month give NRR 88% and GRR 69%
  3. 3LTV over 60 months at 10% discount: $5,254 (simple: $4,800)
  4. 4CAC: $18,000 ÷ 10 = $1,800; payback 12.5 months
  5. 5LTV:CAC: 2.9:1, below the 3:1 rule of thumb
  6. 6Cash: burning $55,000 a month on $900,000; runway 20.7 months, break-even in month 59

LTV:CAC 2.9:1, payback 12.5 months, NRR 88%, growing 79% a year: about $945,000 at 3.1× ARR.

Frequently asked questions

Which SaaS metrics matter most at seed stage?

Retention first: whether the customers you have stay and grow, shown by monthly churn and NRR by cohort. Then CAC payback, to show acquisition can scale, and burn multiple or runway. LTV is less meaningful before you have two years of churn data, so present it as a range.

How do I estimate churn with only a few months of data?

Use customers lost divided by customer-months: three cancellations over 100 customer-months is 3% a month. Small samples swing a lot, so show a range, separate customers who never activated from those who did, and update the figure as cohorts age.
