Methodology & Assumptions
Hasebah uses transparent formulas and editable assumptions. This page explains how we calculate, how we explain, and when you should ask a professional.
Calculation vs. explanation
The calculator computes the number. The AI explains it. The AI does not perform official calculations and does not invent values.
Country-specific assumptions
Every assumption is tied to a country, a category, a source, a confidence level, and a last-updated date. You can always override an assumption to fit your situation.
Hasebah Score
A 0–100 score that summarizes the result. Below 40 is high risk; 40–59 needs caution; 60–79 is acceptable; 80+ is strong. Weights are reviewed per calculator.
Update frequency
Electricity tariffs, fuel prices, and lending rates are reviewed on a defined cadence as official sources publish updates. Every change is logged in the change log.
Limits of the calculators
Results are estimates, not legal, tax, religious, or financial advice. For big decisions, consult a qualified professional.
Global / Other mode
When official country-specific rules are not available, the calculator runs on your custom inputs and clearly labels the result as a general estimate.
