Visible formulas
Every calculator shows its inputs, formula and result labels. You can replace defaults with figures from your own billing, payroll and infrastructure records.
Metric definitions
SaaS metrics vary by accounting policy and cohort window. Read the assumptions beside the calculator and keep the same definitions across periods.
- Revenue figures should use a consistent recognition basis.
- Churn and retention need the same cohort and time window.
- Cost and margin results are estimates until reconciled to actual books.
Corrections
Send the tool URL, inputs, expected result and source when reporting an issue. Confirmed changes receive a new review date and a regression test.
