Retention Rate
The percentage of customers or revenue a business keeps over a defined period.
Also known as: Customer retention rate, Retention
Retention rate measures the percentage of customers, accounts, or revenue that a business keeps over a defined period. It answers a simple but critical question: of everyone you had at the start, how many stayed with you by the end? A high retention rate signals that customers find ongoing value in your product or service, while a low one points to churn problems that can quietly undermine growth.
For B2B teams, retention rate is one of the clearest indicators of long-term health. Winning new logos is expensive, and revenue built on a leaky base grows far more slowly than revenue built on customers who renew and expand. Sales, customer success, and revenue leaders track retention to understand whether the business is compounding or constantly refilling a bucket with holes in it.
How retention rate is calculated
The standard customer retention rate formula compares customers at the end of a period to customers at the start, excluding any new customers acquired during the period so you measure only your ability to keep existing ones.
The formula is: retention rate equals customers at end of period minus new customers acquired, divided by customers at start of period, multiplied by 100. For example, if you began a quarter with 200 customers, ended with 210, and acquired 30 new ones, your retention rate is (210 minus 30) divided by 200, which equals 90 percent.
- Choose a consistent time period (monthly, quarterly, or annually) and stick with it for comparisons.
- Always subtract newly acquired customers so growth does not mask losses.
- Retention rate plus churn rate always equals 100 percent for the same period.
Customer retention versus revenue retention
In B2B, retention is measured in two main ways, and confusing them causes reporting errors. Logo or customer retention counts the number of accounts kept, treating every customer equally regardless of contract size. Revenue retention counts the dollars kept and weights each account by how much it pays you.
Net revenue retention (NRR) includes upsells, cross-sells, and expansions, so it can exceed 100 percent even when some customers leave. Gross revenue retention (GRR) ignores expansion and only measures losses from churn and downgrades, so it caps at 100 percent. A company can lose several small accounts yet still post strong net retention if larger accounts expand.
- Logo retention: percentage of accounts kept, ignoring contract value.
- Gross revenue retention: revenue kept before expansion, always 100 percent or lower.
- Net revenue retention: revenue kept including expansion, can exceed 100 percent.
Where retention rate comes up in B2B
Retention appears across sales, customer success, and finance reporting. Board decks, quarterly business reviews, and investor updates all lean on it because it predicts future recurring revenue and the true return on acquisition spending.
For frontline roles, retention shapes how territories and quotas are structured. Account executives may carry renewal responsibility, customer success managers are often measured directly on retention, and SDRs benefit indirectly because a retained base frees resources for new growth rather than replacing lost revenue.
- Renewal forecasting and revenue planning.
- Customer success team goals and compensation.
- Investor and board reporting on business health.
- Evaluating the payback on customer acquisition cost.
Common mistakes with retention rate
The most frequent error is failing to exclude newly acquired customers, which inflates the number and hides real churn. Another is mixing logo and revenue retention in the same report so stakeholders draw the wrong conclusions.
Teams also compare retention across inconsistent time windows, or report a single company-wide figure that masks big differences between segments. A healthy overall rate can conceal severe churn in a specific customer tier, product line, or acquisition channel.
- Forgetting to remove new customers from the calculation.
- Blending customer and revenue retention without labeling which is which.
- Using different period lengths, making trends unreliable.
- Reporting one blended number instead of segmenting by tier, product, or cohort.
Frequently asked questions
What is a good retention rate in B2B?
It varies by segment and business model, but B2B SaaS companies generally aim for high gross revenue retention in the 80s or 90s percent and net revenue retention above 100 percent. Rather than chasing a universal benchmark, compare against your own historical trend and peers in your category.
What is the difference between retention rate and churn rate?
They are two sides of the same coin. Churn rate measures what you lose and retention rate measures what you keep, so they always add up to 100 percent for a given period. If your quarterly churn is 8 percent, your retention is 92 percent.
Can retention rate be over 100 percent?
Customer or logo retention cannot exceed 100 percent because you cannot keep more accounts than you started with. Net revenue retention can, because expansion revenue from existing customers can more than offset losses from churn and downgrades.
