Our free Retention Rate Calculator is a simple yet powerful digital marketing calculator that helps companies measure how many customers they retain over a specific time period. Whether you run a SaaS, eCommerce store, or agency, customer retention is one of the strongest indicators of long-term success.
What is Retention Rate?
Retention Rate is the percentage of customers a business retains over a given period, excluding new customers acquired during that time.
Formula:
Retention Rate (%) = ((Customers at End – New Customers) ÷ Customers at Start) × 100
Example:
Customers at Start = 1,000
New Customers = 300
Customers at End = 1,100
Retention Rate = ((1,100 – 300) ÷ 1,000) × 100 = 80%
Why Retention Rate Matters?
Shows customer loyalty and satisfaction
Helps predict long-term revenue- Directly impacts Customer Lifetime Value (CLV)
- Guides marketing and retention strategies
- Reduces dependency on costly acquisition campaigns
High retention means customers are happy and engaged, while low retention signals potential issues with product, service, or competition.
