FINANCIAL LOGIC, MADE SIMPLE

Know the rules.
Understand the result.

Explore how income and a custom credit-score rule work together, through a simple interactive educational example.

Educational tool — not a real loan application. These rules are simplified examples from the original Python project. A score of 1,000 is on a custom demo scale and is not a FICO, CIB or bank credit score. No lender uses this calculator to approve loans.

ⓘ

The original Python exercise checks income > 1,000,000 and demo score ≥ 1,000. Both conditions must be true.

02 / BEHIND THE LOGIC

Simple by design

Follow the same decision tree in the website or Python terminal.

01

Check annual income

The educational example requires an annual income greater than 1,000,000 BDT, not equal to it.

02

Check demo score

The custom practice score must be at least 1,000 on a made-up 0–2,000 scale, separate from real credit scoring.

03

Combine the conditions

Both requirements must be satisfied. The result is a demonstration of conditional logic, not an actual lending decision.
