What Is Customer Retention Rate?

Customer retention rate measures the percentage of existing customers who remain active over a given period. Unlike churn rate — which focuses on who left — retention rate focuses on who stayed. It's the flip side of the same coin.

Importantly, this is about customer retention, not employee retention (a common source of confusion in search results). In the subscription business context, retention rate answers: of the customers I had at the start of the period, what percentage are still customers at the end — excluding any new customers I acquired during that time?

Customer Retention Rate Formula

The formula is:

Retention Rate = ((Customers at End − New Customers) ÷ Customers at Start) × 100

The key detail is subtracting new customers acquired during the period. Without this adjustment, you'd be mixing retention performance with acquisition performance.

Example: You start the month with 1,000 customers, acquire 120 new ones, and end with 1,050. Your retention rate is ((1,050 − 120) ÷ 1,000) × 100 = 93%. The inverse churn rate is 7%. Even though your total customer count grew, you lost 70 existing customers during the period.

Retention Rate Benchmarks for Subscription Businesses

Healthy retention rates vary by vertical and billing cycle:

B2B SaaS (annual contracts): 90–97% annual retention is typical. Best-in-class companies exceed 95%. Monthly retention rates for these businesses are 99%+.

B2B SaaS (monthly contracts): 95–98% monthly retention, or roughly 55–80% annual retention. The wider annual range reflects the compounding effect of small monthly differences.

DTC/Ecommerce subscriptions: 80–90% monthly retention is typical. Subscription boxes and consumables tend toward the lower end; digital products and memberships toward the higher end.

Media and streaming: 92–96% monthly retention for established services. New entrants often see 85–90% as they find product-market fit.

How to Improve Your Retention Rate

Retention improvements compound fast — a 1% monthly gain turns into a 12%+ annual improvement. Here's where the biggest gains are.

The cancellation moment is your highest-ROI intervention point. A cancel flow that offers alternatives based on the customer's stated reason (pause for low usage, discount for price sensitivity, plan change for feature gaps) saves 20-40% of customers who start the cancellation process. If you don't have a cancel flow, this is step one.

Onboarding is step two. Customers who don't hit their "aha moment" in the first 7–14 days churn at dramatically higher rates. Map your activation milestones and build nudges that guide new users to value before they lose interest.

Payment failures are the silent retention killer — they account for 20–40% of all churn in many subscription businesses. Smart retry logic and dunning emails recover most of these without the customer even realizing there was a problem. And don't overlook win-back: targeted reactivation campaigns within 30 days of cancellation recover 10–30% of churned customers who already know your product.
