A developer's Day 11 project in the 30 Days of Python series tackles a pressing financial issue for Nigerian and African SMEs. The tool uses Python functions to calculate loan repayments with interest, addressing a common challenge for businesses borrowing from microfinance banks and cooperative societies.

Many SMEs rely on manual calculations with paper or Excel, leading to errors and delays. This project provides a simple, reusable tool for simulating repayment scenarios and tracking multiple loans, helping business owners plan accurately and avoid confusion.

By improving financial literacy and confidence, such tools support SMEs, the backbone of Africa's economy. Accurate planning reduces loan defaults. The project demonstrates practical Python concepts like function creation and reusability to solve real-world problems for market traders and startup founders.
