Illustrative example inputs
These starting values show how the math works. They are not industry averages, customer results or a quote.
| Input | Example value |
|---|---|
Customers enrolled in selected group One defined customer group, counted once each. | 50 |
Enrolled customers with complete observation window Same actual time opportunity to return. | 40 |
Fully observed customers with a recorded return Actual qualifying attendance, not prepaid credits. | 18 |
Fully observed comparison customers Comparable entry/window rule. | 40 |
Comparison customers with a recorded return Customer counted once, even with several visits. | 14 |
Example results
| Measure | Result |
|---|---|
Observation coverage Fully observed customers among entered enrollments. | 80% |
Observed enrolled-group return share Actual returns among eligible fully observed customers. | 45% |
Observed comparison return share Same-window comparison customer share. | 35% |
Calculation detail
| Measure | Result |
|---|---|
| Observed percentage-point return difference | 10 |
| Enrollments still outside a complete observation window | 10 |
| Observed enrolled customers without a recorded return | 22 |
| Comparison customers without a recorded return | 26 |
Model assumptions
- Define an initial attended event and qualifying later attendance.
- Use a complete, comparable observation window before eligibility.
- Count each eligible customer once, regardless of number of returns.
- Purchased credits and subscriptions do not establish attendance or causation.
Read alongside these results
- No credit, offer, appointment or attendance record is changed.
- Pending observation is not a lost customer.
- Shares are descriptive, not proof the program caused returns or improved health.
Download this worked example (CSV). Use the interactive version to export your own inputs and results.
A customer buys a prepaid package but has only one recorded visit. Which event belongs in the repeat-attendance report? Use actual attendance and a complete observation window. A sale is a commercial event, not proof of a return. One person's several later visits do not become several returning customers in a customer-level cohort.
The tool above reviews enrolled, fully observed and returned customers with fictional starting counts. Enter authorized totals instead of individual names or histories. The worksheet changes no membership or visit record and predicts no future return. It displays descriptive customer shares, not proof a program caused attendance or produced a health benefit for anyone.
Use with this guide
Review actual program availability
Access and messaging readiness are not attendance records.
Review fulfillment economics separately
A cost scenario does not establish incremental demand.
Measure a wellness-class reminder against attended seats
One class booking needs one actual attendance outcome. Several messages about the same booking do not create several seats.

Define the customer and complete observation window
Define the initial attended event, qualifying later attendance and observation window before counting returns. Use one documented customer identity rule in the proper system. Deduplicate under that rule without importing the person-level data here. An enrollment entered yesterday has not had the same opportunity to return as one entered months earlier and should not silently become a failure.
Mark the observation date and identify customers whose full window has elapsed. Keep pending observations separate from fully observed customers without returns. HubSpot documents task owners, due dates and associated records. Use equivalent fields for missing source checks, while visit evidence stays in its authorized record. A completed task establishes neither a return visit nor an attended class.

Keep prepaid sales outside the attendance numerator
Keep purchased credits, subscriptions and deposits outside the attendance numerator unless an actual qualifying visit occurred. An active package might still be unused. Attendance and revenue recognition answer different questions. The SBA's contribution guidance separates price, variable costs and fixed expenses. A customer-return share is not a calculation of accounting income, fulfilled reward cost or incremental profit.
Count each eligible customer once whether they attended one or several later classes. If analyzing individual seats or bookings, use a separate attendance report with its own unit. Review comparable observation windows for the enrolled and comparison groups. Different entry rules, availability or customer mix limit interpretation even when the displayed shares look straightforward and complete.

Read the fictional observed-return comparison
The fictional enrolled group contains 50 customers, of whom 40 have a complete observation window and 18 have recorded returns. Observation coverage is 80 percent. Return share among fully observed customers is 45 percent. The comparison group has 40 fully observed customers and 14 returns, a 35 percent share. These figures are illustrative, not wellness benchmarks or client results.
The observed return difference is ten percentage points. Ten enrollments remain outside a complete window. Twenty-two fully observed enrolled customers and 26 comparison customers lack recorded returns. NIST discusses proportions and separate statistical questions. This descriptive tool proves no causation or statistical significance. Empty eligible groups leave the relevant rate and comparison unavailable instead of manufacturing a zero retention result.

Review actual sources before changing the offer
BlueFinch's optional paid loyalty service requires accepted terms, activation and applicable allowances. Customer permission and channel readiness apply, with the relevant registration process for SMS. Confirm actual enabled features and source connections. Software access does not establish customer attendance, guarantee returns or replace the class system. Use the business's real visit evidence for this report.
Download the cohort for the owner review. Answer offer and communication questions separately from the attendance measure. A pending enrollment is not a lost customer, and a prepaid purchase is not a completed return. Tie later observations to their original group and report changes only when the proper source and stated counting rule support the update.
