Methodology
Great Future separates calculation logic, dated rules and presentation so results can be tested and reviewed.
Reviewed 21 September 2026Calculations and dated rules
Calculator formulas live in tested domain packages rather than page components. Changeable statutory or institutional rules carry an effective date, official source and verification date. Tool pages identify method versions, assumptions and review dates where applicable.
Results are planning estimates. Payroll, credit, tax, education and other official outcomes can differ because contracts, timing and individual facts matter.
Privacy and review
Core calculator and document inputs are processed in the browser where the tool states that model. Raw financial, educational, date, document and personal inputs are excluded from analytics events.
Stable universal methods and changing rules have different review schedules. Material changes require focused tests, full repository checks and static export evidence before release.
