CRR (%) = ((End Customers - New Customers) / Start Customers) × 100About this tool
Customer Retention Rate (CRR) reflects the percentage of active subscribers who remain paying customers over a defined timeframe, deliberately excluding any new acquisitions added during that window. For subscription businesses, customer retention rate is the mathematical inverse of customer churn rate: retaining 94% of your accounts over a month directly correlates to a 6% monthly churn rate. Tracking CRR across quarterly and annual milestones highlights long-term account stickiness and helps teams identify the inflection points where user engagement decays. Higher retention rates dramatically reduce customer acquisition payback pressures and amplify the lifetime value (LTV) of every marketing dollar spent. Use this calculator to measure retention consistency across monthly, quarterly, or annual cohorts.
How It Works

- 2Enter the total number of customers active at the end of the period (E).
- 3Enter the number of brand new customers acquired during the period (N).
- 4View your Customer Retention Rate and corresponding churn percentage.
Formula & Math
Transparent LogicCRR (%) = ((End Customers - New Customers) / Start Customers) × 100
Worked Practical Example
A SaaS company begins January with 250 customers, ends with 280 customers, and signed up 50 new accounts during the month.
Calculation / Steps
((280 - 50) / 250) × 100 = (230 / 250) × 100 = 92.00%
Expected Result
92.00% customer retention rate (8.00% monthly churn).
Frequently Asked Questions
Why subtract new customers from the ending customer total?+
If you don't subtract new customers, your acquisition volume disguises your true attrition, producing a misleading figure that conflates marketing success with retention quality.
How does CRR relate to customer lifetime?+
Average customer lifetime in months can be estimated as 1 / (1 - CRR in decimal form). A 95% monthly retention rate yields an average lifespan of 20 months.
What timeframe should I use for CRR?+
Match the timeframe to your billing cycle. Monthly plans call for monthly CRR. Annual plans are better measured over twelve months, because those customers can only leave at renewal.
