How to read the result

Above 100% means the customers you already had are worth more than they were, before any new sale. Below 100% means new sales first have to refill what leaked.

Read it beside gross retention. A high NRR built on a few large expansions can sit on top of heavy churn that gross retention will show.

The formula

Retention

NRR = (starting MRR + expansion − contraction − churn) ÷ starting MRR.

GRR leaves expansion out.
