NDR Cohort
Net Dollar Retention by Cohort shows how recurring revenue from customers evolves over time based on their sign-up month. The report groups customers into cohorts and tracks how their Monthly Recurring Revenue changes in subsequent months.
In Rillet, each cohort is defined by the customer’s sign-up month.
What This Report Shows
The Net Dollar Retention by Cohort report displays recurring revenue retention for each sign-up cohort across multiple months.

The table includes the following elements:
Sign-Up Month Defines each cohort based on the month customers first generated recurring revenue.
Cohort MRR The total Monthly Recurring Revenue generated by customers who signed up in that month.
Retention Columns Columns labeled In-Month, Month 1, Month 2, and subsequent months show how revenue from that same group of customers changes over time.
Average Displays the average retention percentage across all cohorts for each month.
Each row represents customers who began generating recurring revenue in the same month. The In-Month column represents the baseline revenue level for that cohort. Subsequent columns display how revenue from that same group changes in later months.
How Net Dollar Retention by Cohort Is Calculated
For each cohort, the system compares recurring revenue in the initial month with recurring revenue in later months.
The calculation follows this formula:
The system defines each value as follows:
Cohort MRR in the Initial Month (M0) The total recurring revenue generated by customers in their sign-up month. This is your baseline (100%).
Cohort MRR in a Given Month (Mn) The total recurring revenue from the same customers in a later month.
The In-Month column represents the baseline value of 100 percent. Future months reflect revenue changes from that original cohort, including expansion, contraction, or churn.
