What it measures

Understanding Gross Revenue Retention

Calculate recurring revenue retained before expansion from an opening customer cohort. Unlike net revenue retention, GRR excludes expansion and therefore exposes the durability of the original recurring-revenue base.

Interpretation

What the result means

A 90% result means the cohort retained 90% of its opening recurring revenue before any upsell or expansion.

Action

How to use it

Track by cohort, segment, plan, and contract size and reconcile every contraction and churn movement to the MRR bridge.

Limits

What it leaves out

Currency, pauses, credits, reactivations, migrations, usage revenue, and cohort rules can materially alter reported retention.

The math

Gross Revenue Retention formula

GRR = (Starting MRR - Contraction MRR - Churned MRR) / Starting MRR x 100

Worked example

Example calculation

A $500,000 opening cohort loses $18,000 to contraction and $32,000 to churn.
Calculation
($500,000 - $18,000 - $32,000) / $500,000 x 100
Result
90% GRR

Frequently asked questions

Which inputs should I use for Gross Revenue Retention?

Use starting cohort mrr, contraction mrr, churned mrr, measured from the same source and period. Include only values that match the definitions shown beside each field.

Why might two Gross Revenue Retention calculations differ?

The systems or accounting policies may define starting cohort mrr, contraction mrr, churned mrr differently. Compare the time period, scope, source, and treatment of exceptional items before comparing results.

How often should I recalculate Gross Revenue Retention?

Recalculate when any input changes materially and on the same reporting cadence used for the decision. Save the source and date of each input so the trend remains comparable.

Can I use Gross Revenue Retention by itself?
