Net Revenue Retention (NRR)
Net Revenue Retention measures how much revenue a SaaS or subscription company retains from its existing customer cohort over a twelve-month period after accounting for churn, contraction, and expansion, with a figure above 100 per cent indicating that upsells and expansions more than offset losses.
NRR — also called net dollar retention (NDR) in dollar-denominated businesses — is the most comprehensive single metric for evaluating the revenue quality of a subscription business. Unlike gross revenue retention which only measures how much revenue is retained from customers who stay, NRR incorporates the full commercial relationship with the existing customer base: what is lost through churn and downgrades, and what is gained through upsells, cross-sells, and seat expansions.
The calculation takes the beginning-of-period ARR for a defined customer cohort, adds any expansion revenue earned from that cohort during the period, subtracts any contraction (downgrade) revenue, subtracts any churned revenue, and divides the result by the beginning ARR. The output is expressed as a percentage. An NRR of 115 per cent means that even if the company acquires zero new customers, its existing customer base will generate 15 per cent more revenue next year than it did this year through organic expansion within the account base.
NRR above 100 per cent is considered the hallmark of a high-quality SaaS or subscription business because it means the company can grow revenue from its existing base alone — net new customer acquisition adds to this organic engine rather than being the sole driver of growth. Best-in-class enterprise software companies globally have reported NRR of 120 to 130 per cent, indicating powerful land-and-expand dynamics.
In India, listed software product companies rarely disclose NRR in the standardised way that US-listed SaaS companies do under SEC reporting conventions, making it harder to benchmark. However, companies like Newgen Software and Nucleus Software have discussed the proportion of revenues from existing customers versus new customers, which provides indirect evidence of retention quality. As more Indian SaaS companies listed or disclosed metrics to institutional investors, NRR was increasingly requested in analyst calls as a standard KPI.
For investors evaluating Indian IT companies that have begun transitioning from project-based to subscription models, building an implied NRR estimate from disclosed recurring revenue cohort data provides a powerful insight into whether the subscription business is genuinely healthy or is experiencing high churn masked by aggressive new logo acquisition.
