Customer Reactivation Rate Calculator

Measure how effectively you win back churned customers — and the MRR recovered from win-back campaigns.

Reactivation rate measures the percentage of churned customers who return and become paying customers again. Reactivated customers typically have lower CAC than new customers (they already know your product) and often have better retention. A 5–15% reactivation rate is typical for SaaS win-back campaigns.

The Formula

Reactivation Rate = Reactivated Customers ÷ Churned Customers Contacted × 100

In plain English

Divide reactivated customers by total churned customers contacted. Multiply by 100.

Worked Example

18 reactivated ÷ 200 contacted = 9% reactivation rate. MRR recovered: 18 × $150 = $2,700/mo.

Win-Back Campaigns — High ROI, Low CAC

Churned customers already know your product and brand. Win-back CAC is typically 30–50% of new customer CAC. Even a low reactivation rate can produce significant MRR at minimal cost.

Best win-back segments: customers who churned due to price (offer discount), due to missing features (announce new capabilities), or due to no time (offer concierge onboarding). Customers who churned due to poor fit are rarely worth pursuing.

Common Mistakes

⚠️

Contacting all churned customers with the same message

Churned customers leave for different reasons. Segment by churn reason and personalise the win-back message — price-sensitive churners need a discount, feature-gap churners need a product update announcement.

⚠️

Waiting too long to attempt win-back

The ideal win-back window is 30–90 days post-churn. After 6 months, customers have moved to competitors and the chance of return drops dramatically. Automate win-back sequences to trigger immediately after churn.

⚠️

Not measuring reactivated customer lifetime

Track whether reactivated customers have better or worse retention than new customers. If they churn again quickly, win-back effort is wasted on non-viable customers.
