Retention Rate
Retention rate is the percentage of customers (or users) who remain active over a period — the mirror image of churn. Calculated as customers retained divided by customers at the period's start, it measures whether a product delivers durable, repeated value rather than a one-time hit, and underpins almost every other growth metric.
Key takeaways
- Retention rate is the share of customers or users still active over a period — the mirror image of churn.
- Measure it at three altitudes: logo (account), revenue (dollar, including expansion), and user (engagement) retention.
- A cohort retention curve that flattens to a plateau proves durable value; one that decays toward zero signals no lasting hook.
- Net revenue retention above 100% marks a compounding business where existing customers more than replace those who leave.
Retention is measured at three altitudes. Logo (account) retention asks whether customers stay; revenue (dollar) retention asks whether the money stays, including expansion; and user (engagement) retention asks whether individual people keep showing up. A product can retain logos while quietly losing engaged users inside each account — an early warning that the logo will eventually leave too.
The clearest way to see retention is a cohort retention curve: group users by when they joined, then plot the share still active at week 1, 4, 12, and beyond. A healthy curve flattens to a stable plateau, proving a core of users found lasting value. A curve that decays toward zero signals the product has no durable hook, no matter how strong acquisition looks.
Net revenue retention (NRR) above 100% is the signature of a compounding business: existing customers spend more over time than the ones who leave take away. Investors scrutinize NRR precisely because it isolates product value from new-logo acquisition spend.
Planoda builds retention curves from real completion and activity events, so teams can watch whether a cohort's engagement holds the same place they watch throughput and cycle time.

- Churn RateChurn rate is the percentage of customers (or revenue) lost over a period, calculated as customers lost divided by customers at the start of the period. It is the inverse of retention and the single most-watched health metric for subscription businesses, because small monthly losses compound into large annual ones.
- Cohort AnalysisCohort analysis groups users by a shared starting characteristic — most often their signup or first-purchase date — and tracks how each group behaves over time. By comparing cohorts side by side, it separates the effect of when someone joined from the effect of how long they have been around, revealing trends that blended averages hide.
- DAU/MAU RatioThe DAU/MAU ratio divides daily active users by monthly active users to gauge engagement intensity — the share of a product's monthly audience that returns on a typical day. Expressed as a percentage, it is a stickiness measure: a ratio of 50% implies the average monthly user is active about fifteen days a month.
- Customer Lifetime Value (LTV)Customer Lifetime Value (LTV or CLV) is the total profit a business expects to earn from a customer across the entire relationship. A common estimate is average revenue per customer times gross margin, divided by churn rate. LTV quantifies what a customer is truly worth, setting the ceiling on what a business can sensibly spend to acquire and keep them.
- Activation RateActivation rate is the percentage of new users who reach a defined first-value milestone — the moment they experience the product's core benefit. Sitting between signup and retention in the funnel, it measures whether onboarding actually delivers on the promise that brought users in, and is one of the strongest early predictors of whether they will stay.
