Net revenue retention as a GTM metric
For years, go-to-market in B2B SaaS focused almost entirely on new logos. Today, net revenue retention (NRR) is recognised as one of the most important indicators of long-term growth – and it belongs at the centre of the GTM plan.
What NRR measures
NRR shows how much recurring revenue you keep and grow from existing customers over a period, including expansion, contraction and churn.
Formula: NRR = (Starting ARR + Expansion – Contraction – Churn) ÷ Starting ARR
Example: Starting ARR of £1m, £200k expansion, £50k contraction and £80k churn gives NRR of 107%.
An NRR above 100% means your existing customer base grows even without new sales.
Why NRR belongs in the GTM plan
It reduces dependence on new business
Strong NRR lowers the pressure on acquisition to hit growth targets.
It reveals ICP quality
Customers who churn quickly or never expand are often a sign of poor fit – feedback that should shape targeting.
It improves unit economics
Expansion revenue typically costs far less to acquire than new logo revenue, improving CAC payback.
How to make NRR part of GTM
- Set an NRR target alongside new business targets in the annual plan
- Give customer success a revenue number, not just health scores
- Share churn and expansion data with marketing and sales to refine the ICP
- Define clear ownership for renewals and expansion between CS and account management
- Build expansion into pricing and packaging, with a value metric that grows with usage
Leading indicators to watch
- Product usage and adoption trends
- Number of active users per account
- Executive sponsor engagement
- Support ticket volume and sentiment
Conclusion
New logos build the base, but retention and expansion determine how efficiently a SaaS business grows. Putting NRR into the GTM plan aligns every team around the full customer lifecycle.
