Calculate net and gross revenue retention from expansion, contraction and churn.
NRR includes expansion revenue and can therefore exceed 100 per cent, while gross retention excludes it and is capped at 100. Comparing the two separates genuine account growth from the underlying churn rate. An NRR above 100 per cent means revenue grows even with no new customers, which is what allows a business to compound without proportional sales spend.
Net Revenue Retention (NRR)
NRR = (start + expansion − contraction − churn) ÷ start; GRR excludes expansion
