Enter Segment Inputs

Use direct ending size, or leave it blank and let the tool calculate ending size from additions, reactivations, and churn.

Example Data Table

Segment Beginning Size New Reactivated Lost Ending Size Growth Rate
SMB Trial 420 88 12 40 480 14.29%
Mid-Market 150 24 6 10 170 13.33%
Enterprise 75 8 2 3 82 9.33%
Expansion Risk 96 7 1 11 93 -3.13%

Formula Used

Ending Segment Size
Ending Size = Beginning Size + New Customers + Reactivated Customers − Lost Customers
Segment Growth Rate
Growth Rate (%) = ((Ending Size − Beginning Size) ÷ Beginning Size) × 100
Acquisition and Churn Rates
Acquisition Rate (%) = ((New + Reactivated) ÷ Beginning Size) × 100
Churn Rate (%) = (Lost ÷ Beginning Size) × 100
Retention Rate
Retention Rate (%) = ((Beginning Size − Lost) ÷ Beginning Size) × 100
Annualized Growth Rate
Annualized Growth (%) = (((Ending Size ÷ Beginning Size) ^ (1 ÷ Years)) − 1) × 100
Pipeline Growth Rate
Pipeline Growth (%) = ((Ending Pipeline − Beginning Pipeline) ÷ Beginning Pipeline) × 100

How to Use This Calculator

Enter the segment name first so your exported report stays labeled. Add beginning size, customer movements, and pipeline values for the selected time window.

You may either provide the ending segment size directly or leave it empty to let the tool calculate it from additions, reactivations, and losses.

Choose the period length and unit to calculate annualized growth correctly. Add a target growth rate if you want to measure the gap between actual and planned performance.

Press the calculate button. The tool shows detailed results above the form, including growth, churn, retention, pipeline changes, efficiency, and projected next-period size.

Use the export buttons to save the results as CSV or PDF for pipeline reviews, team meetings, board updates, or forecasting documentation.

Frequently Asked Questions

1. What does segment growth rate measure?

It measures how much a customer or pipeline segment increased or decreased over a chosen period. It highlights momentum, contraction, and whether segment-specific strategy is working.

2. Can I leave ending size empty?

Yes. The calculator can derive ending size from beginning size, new customers, reactivations, and lost customers. That is useful when teams track flows rather than final counted totals.

3. Why include reactivated customers separately?

Reactivated accounts reflect recovery performance. Tracking them separately helps distinguish fresh acquisition from win-back activity, which improves campaign evaluation and retention strategy analysis.

4. What is annualized growth?

Annualized growth converts the observed segment change into a yearly equivalent. It helps compare segments fairly when their reporting periods differ in days, months, quarters, or years.

5. Why is pipeline value included?

Segment size alone can hide quality differences. Pipeline value shows whether growth added commercial value or only increased volume without improving expected revenue potential.

6. What does net add efficiency mean?

Net add efficiency compares net growth against total additions. A lower figure can signal that strong acquisition is being offset by churn, downgrade, or poor segment fit.

7. When is a negative growth rate useful?

A negative value is useful because it reveals contraction early. Teams can investigate churn, product mismatch, pricing problems, or market saturation before revenue impact becomes severe.

8. Who should use this calculator?

CRM managers, RevOps teams, sales leaders, lifecycle marketers, and founders can all use it to monitor segment health, compare performance, and support better resource allocation.
