01
Governance self-assessment
Make a first-pass assessment across five equally weighted dimensions.
Enter your assumptions, then calculate.
Formula: (Ownership + quality + lineage + access + standards) / 25 × 100
An unvalidated self-assessment with equal weights. It is not certification, an audit or a compliance verdict. Record evidence and uncertainty for each rating; the number does not establish maturity.
02
Migration payback estimate
Compare a one-time investment with a positive change in monthly cost.
Enter your assumptions, then calculate.
Formula: One-time migration cost / (current monthly cost − future monthly cost)
Simple cash payback, not an investment recommendation. Time value of money, tax effects and costs you have not entered are excluded. There is no positive payback when future cost is at least current cost.

Your data and calculation method
Inputs, results and notes are processed in this browser. No scenario data is uploaded. Save stores one scenario per hub in this browser profile; anyone using the profile may be able to read it. Delete saved removes that copy. Exported files remain yours to manage.
Exact decimal inputs; rational arithmetic; final result rounded to 2 places, half away from zero. Blank inputs stay unknown. Each calculator uses the units shown; money is USD and no currency conversion is performed.
