What retention rate measures: Retention rate is the percentage of existing customers who remain customers over a period. If you started with 1,000 customers and ended with 900 after adding 100 new ones, your retention is (900 − 100) / 1,000 = 80%. That means 20% of your original customers left.
The formula explained: Retention = (End Customers − New Customers) / Start Customers × 100. This isolates your existing customer base from new acquisitions. Without subtracting new customers, you would overstate retention because new sign-ups inflate the ending count.
Retention vs churn: Benchmarks by industry: SaaS companies aim for 90–95% monthly retention (5–10% churn). Consumer subscriptions in Chicago and Miami run 80–90% monthly. Gyms and salons run 70–85% monthly. A New York fintech with 95% monthly retention retains 54% of customers after 12 months — solid for financial services. How to improve retention: Onboard new customers immediately (first 7 days are critical), identify at-risk users before they churn (low engagement is a leading indicator), offer annual plans with discounts to lock in commitment, and survey churning customers to understand why they leave. Every 1% improvement in retention can increase lifetime value by 5–10%.

Frequently Asked Questions
- What is a good retention rate?
- For SaaS, 90–95% monthly is excellent. For consumer subscriptions, 80–90% monthly is solid. For gyms and salons, 70–85% monthly is typical. Always compare within your industry and business model.
- How do I calculate without new customer data?
- You need the new customer count to isolate existing customer retention. Without it, you cannot distinguish between customers staying and new customers inflating the numbers. Track new sign-ups separately.
- Should I measure monthly or annually?
- Both. Monthly retention shows short-term health and product engagement. Annual retention shows long-term value and is what investors and acquirers look for. A 95% monthly retention is 54% annual — both numbers matter.
- What if retention is over 100%?
- This means more existing customers stayed than you started with — possible if you count reactivated customers or have data errors. Check your definitions: are you counting people or accounts? Are reactivations included?
- How does retention relate to LTV?
- Lifetime Value = ARPU / Churn Rate. If your monthly ARPU is $50 and churn is 5%, LTV = $1,000. Improving retention from 95% to 97% monthly increases LTV from $1,000 to $1,667 — a 67% improvement.
- Can retention be negative?
- No — retention ranges from 0% (all customers left) to 100% (no customers left). If your calculation shows negative, you likely have a data error — more new customers than ending customers means your end count is wrong.
