What Are Good Results and What Are Bad Results from This Calculator?

A good retention rate indicates that you’re keeping a high percentage of your customers-meaning they love what you offer and keep coming back. Generally, anything above 80% is considered fantastic in most industries.

A bad retention rate means a significant portion of your customers are leaving after their first purchase or engagement. If your retention is dipping below 40%, it might be time to revisit your customer engagement strategies or improve your customer experience.

3 Realistic Examples of Good Results (And Why They’re Good)

90% retention rate over 6 months: This shows strong customer loyalty and satisfaction. Customers aren’t just buying once-they’re returning, which means you’re offering great value.
85% retention rate for a subscription service: Excellent! This means customers see ongoing value in your service and are likely to stay subscribed for longer.
75% retention rate for a growing e-commerce store: Solid results, especially if you’re still scaling. It shows customers are enjoying what you offer and coming back for more.

3 Realistic Examples of Bad Results (And How to Fix Them)

30% retention rate for a new business: Yikes! A low retention rate means you’re not engaging your customers post-purchase. Try improving your onboarding process or offering more incentives to return.
50% retention rate in a saturated market: This could mean your competitors are grabbing your customers’ attention. A loyalty program or personalized marketing campaigns could help increase your retention.
40% retention rate for a subscription service: Ouch. Time to assess why subscribers are leaving-perhaps there’s a disconnect between what’s promised and what’s delivered. Consider adding more value to your service, such as exclusive content or discounts.

History and Future of the Customer Retention Rate Calculator
