Retention Rate

Definition Retention rate measures the percentage of customers, or revenue, a business successfully retains over a specific period. It is the clearest indicator of product-market fit and customer satisfaction.

Customer Retention vs. Revenue Retention In subscription models (like SaaS), retention is split into two distinct tracking categories:

1. Customer (Logo) Retention This measures the raw number of accounts that stayed. If you start the year with 100 customers and 10 cancel, your logo retention is 90%. While useful, this metric treats a $100/month customer and a $10,000/month customer equally, which can misrepresent the financial health of the business.

2. Gross Revenue Retention (GRR) GRR measures the percentage of recurring revenue retained from the existing customer base, excluding any revenue from upsells or cross-sells. The maximum possible GRR is 100%. A high GRR (typically 90%+) indicates that the core product is sticky and customers are not downgrading or churning.

3. Net Revenue Retention (NRR) NRR is arguably the most important metric in a subscription business. It measures total retained revenue including expansions (upsells, cross-sells, price increases) minus contractions (downgrades, churn).

• NRR = (Starting Revenue + Expansion Revenue - Contraction Revenue - Churn) / Starting Revenue

If your NRR is over 100% (e.g., 115%), it means your existing customer base is growing financially faster than you are losing money to churn. A company with >100% NRR can theoretically grow its overall revenue without acquiring a single new customer.

Cohort Analysis Retention is typically analyzed in cohorts (grouping customers by the month or quarter they signed up). Cohort analysis helps teams identify specific lifecycle drop-off points. If the data shows that 40% of users churn in Month 3, the business knows exactly where to focus its customer success and onboarding efforts.
