THE NUMBERS, EXPLAINED
How to use this calculator.
Mutually exclusive reason per account; supplied cohort can be filtered before entry. Gross contraction excludes new accounts and expansion offsets.
Start with your inputs
Enter beginning recurring revenue by account (currency), ending recurring revenue by account (currency), reason code by account (1=seats, 2=plan, 3=other). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Beginning recurring revenue by account (currency) | 100,200,300 |
| Ending recurring revenue by account (currency) | 80,150,350 |
| Reason code by account (1=seats, 2=plan, 3=other) | 1,2,3 |
A worked example
With the example inputs above, gross contraction by account (currency) is 20, 50, 0. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Gross contraction by account (currency) | 20, 50, 0 |
| Contraction by reason: seats, plan, other | 20, 50, 0 |
| Gross recurring-revenue contraction (currency) | 70 |
How this is calculated
Gross contraction by account (currency)
Keep only decreases and do not net them against expansions.
Contraction by reason: seats, plan, other
Aggregate each account decrease under its supplied exclusive reason.
Gross recurring-revenue contraction (currency)
Add all account decreases independently of positive changes.

Assumptions and limits
Mutually exclusive reason per account; supplied cohort can be filtered before entry. Gross contraction excludes new accounts and expansion offsets.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Gross contraction by account (currency); Contraction by reason: seats, plan, other; Gross recurring-revenue contraction (currency). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Mutually exclusive reason per account; supplied cohort can be filtered before entry. Gross contraction excludes new accounts and expansion offsets.
