Formula shown
(950 − 100) ÷ 1,000 × 100 = 85.00%
Target scenario: 90.0%
Retain 50 more starting customers to reach the target.
That means retaining 900 starting customers and ending with 1,000 total customers if new acquisitions stay at 100.
Customer churn is shown as 100% minus retention for this same starting cohort. It is not revenue churn and does not reveal which customers or revenue were retained.
Transparent calculation
retention rate formula
Subtract customers acquired during period से ending total करने के लिए isolate people who could have belonged करने के लिए starting cohort. Divide that retained count by starting cohort और multiply by 100.
Customer retention rate
(ending − new) ÷ starting × 100
Example: start के साथ 1,000 customers, end के साथ 950, और acquire 100 during month. Retained customers हैं 850, so retention है 85%. matching customer churn complement है 15%.
Measurement discipline
Keep cohort और period consistent
arithmetic है simple; definitions determine whether answer है useful. Document these choices पहले comparing periods या teams.
01
Define active consistently
इस same rule के लिए active customer या user at both cutoffs. paid account, login, purchase, या subscription renewal कर सकते हैं produce different retention rates.
02
Align start और end cutoffs
Use करें one timezone, reporting source, और complete time window. Partial days और late-arriving events कर सकते हैं distort short periods.
03
Separate नए acquisitions
Subtract केवल customers who joined बाद period began. Otherwise growth कर सकते हैं hide losses से starting cohort.
04
Decide how reactivations count
Choose करें whether returning customers हैं नए, retained, या reported separately, then apply that policy करने के लिए every comparison.
Interpretation और limits
इस target as planning scenario
calculator converts target percentage में required retained-customer count. It does नहीं predict behavior या prescribe universal benchmark.
Retention versus churn
For same starting cohort, customer churn है complement का retention: 100% minus retention rate.
Customer versus revenue retention
This page counts customers या users. Gross और net revenue retention use recurring revenue और require different inputs.
Compare करें like के साथ like
monthly product-user cohort चाहिए नहीं be compared directly के साथ annual contract renewals बिना explaining different window और eligibility rules.
Segment पहले acting
overall rate कर सकते हैं hide differences by plan करें, channel, region, tenure, या use case. Calculate करें separate cohorts पहले deciding what करने के लिए change.
