Age 15Explain it to a 15-year-oldConnect it to the formula
Exclude upgrades and expansion so the metric isolates preservation of the original recurring-revenue base. The rule is GDR = (starting revenue − churn − contraction) ÷ starting revenue × 100. Its input values are Starting recurring revenue, Churned recurring revenue, Contraction recurring revenue, Expansion recurring revenue, and the main result is Gross dollar retention. Try changing one number and watch what happens to Gross dollar retention.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is GDR = (starting revenue − churn − contraction) ÷ starting revenue × 100, evaluated from Starting recurring revenue, Churned recurring revenue, Contraction recurring revenue, Expansion recurring revenue to produce Gross dollar retention. Exclude upgrades and expansion so the metric isolates preservation of the original recurring-revenue base. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Measure beginning recurring revenue retained before expansion revenue.
Why the business model works
Exclude upgrades and expansion so the metric isolates preservation of the original recurring-revenue base.
Inputs and operating assumptions
This model uses Starting recurring revenue, Churned recurring revenue, Contraction recurring revenue, Expansion recurring revenue. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
GDR = (starting revenue − churn − contraction) ÷ starting revenue × 100
What the calculator produces
The primary output is Gross dollar retention; it also exposes Net dollar retention, Recurring revenue lost before expansion. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
