Gross Revenue Retention (GRR)

The percentage of recurring revenue retained from existing customers over a period, including expansion revenue from upsells and cross-sells. NRR above 100% indicates that growth from existing customers outpaces losses from churn, a hallmark of strong product-market fit.

The percentage of customers (measured by count, not revenue) that remain active over a given period, regardless of changes in their contract value. Logo retention — also called customer retention rate or gross retention by customer count — isolates the frequency of customer loss from revenue expansion or contraction and is a key indicator of product-market fit and customer satisfaction.

The total predictable revenue a subscription business earns each month, normalised to exclude one-time charges. MRR is tracked as new MRR, expansion MRR, contraction MRR, and churned MRR to understand the drivers of revenue movement.

A method of tracking the behaviour of groups of customers (cohorts) who share a common characteristic — typically their acquisition date — over time. Cohort retention analysis reveals whether product improvements are genuinely improving customer retention by isolating the performance of each intake group, and is essential for forecasting lifetime value and revenue trajectory in subscription businesses.

A valuation multiple calculated by dividing enterprise value by revenue, used to value businesses where profitability is not yet meaningful — such as early-stage companies, high-growth SaaS businesses, and pre-profit biotech firms. EV/Revenue is less susceptible to manipulation through accounting choices than earnings-based multiples but provides less insight into operating efficiency.

Revenue minus the cost of goods sold (COGS), expressed as a percentage of revenue. Gross margin indicates how efficiently a company produces its goods or delivers its services and determines how much revenue is available to cover operating expenses and generate profit.

Revenue that is contractually expected to continue on a regular basis, such as subscriptions, maintenance contracts, or licensing fees. Recurring revenue is more predictable than one-time sales and is valued at higher multiples because it reduces risk and improves forecasting accuracy.

Total revenue divided by the number of employees, providing a high-level measure of workforce productivity and operational efficiency. Revenue per employee varies significantly by industry and business model, and is influenced by the level of automation and intangible asset investment.

SaaS Intangible Assets: ARR, Churn, and Customer Value

SaaS businesses generate value through intangible assets that compound over time — customer relationships measured by ARR and retention, technology platforms that scale without proportional cost, and data assets that improve with usage. Understanding the intangible asset composition of a SaaS business changes how you value it.

What is Net Revenue Retention (NRR)?

NRR measures the revenue retained from a cohort of customers plus expansion revenue (upsells, cross-sells) minus churn, expressing it as a percentage of starting revenue.

How is the Rule of 40 calculated and when does it apply?

The Rule of 40 states that a healthy SaaS company's revenue growth rate plus profit margin should exceed 40% — it applies primarily to SaaS companies at scale and is used by investors to assess growth-profitability balance.
