Net new revenue is the actual revenue growth in a period after accounting for losses: new plus expansion revenue, minus churned and contracted revenue. It shows whether the business genuinely grew, cutting through gross additions that can hide heavy losses underneath.

Net new revenue is the honest growth number. Gross new revenue can look impressive while churn quietly eats most of it, leaving you exhausted and barely ahead. Net new strips that illusion away by subtracting what you lost. If your gross additions are strong but net new is weak, the problem is not acquisition, it is the leak underneath it.

Example:

Adding $200k in new and expansion revenue while losing $150k to churn produces just $50k in net new revenue. The gross number flattered a near-standstill.

Why is net new revenue more honest than gross additions?

Gross additions ignore losses. Net new subtracts churn and contraction, revealing whether the business actually grew rather than just added before losing.

What does weak net new revenue with strong gross additions indicate?

A retention problem. You are acquiring well but losing nearly as much, so the leak, not acquisition, is the constraint.
