A new version of Financial Calculator has been released!🎉

Shahab Baradaran Dilmaghani (bdshahab) — Thu, 05 Feb 2026 07:12:57 +0000

Version 7.9

The payment section has been corrected, making it possible to properly verify payments.

Version 7.10

Fixed bugs related to the background color of the number input boxes.

The payment system bug was discovered in the early days of 2026. However, due to a complete internet outage in Iran🇮🇷, resolving the issue took nearly a month.
The issue introduced in version 7.9 was fixed within one day and was caused by technical incompatibilities.

To prevent similar situations in the future, a new option has been added that allows the software to be used for free. This ensures you can continue using the application without waiting for the next release.

Due to ongoing internet limitations in Iran🇮🇷, a Linux🐧 version cannot be released at this time. It will be made available as soon as a stable connection allows.

Payment section is under maintenance

Shahab Baradaran Dilmaghani (bdshahab) — Sun, 04 Jan 2026 20:59:03 +0000

We’re currently working on improving the payment section of Financial Calculator. It’s under maintenance🛠 for now, and a new version with a more reliable payment system will be released in a few days. Thank you for your patience.🙏

New Version of Financial Calculator Released 🎉

Shahab Baradaran Dilmaghani (bdshahab) — Tue, 30 Dec 2025 16:09:37 +0000

A new version of the Financial Calculator is now available.

This update mainly improves window behavior on Linux, where some dialogs could previously appear without blocking the main window. This sometimes made it hard to notice or close error messages. The issue has now been fixed to provide a smoother and less confusing experience.

These changes also help future compatibility with Windows, should similar behavior occur there.

Additionally, there is a very small visual update to the error icon in the Internet section. This change is subtle and only visible when the product is not purchased—most users won’t notice any difference.

The Evolution of the Financial Calculator Software

Shahab Baradaran Dilmaghani (bdshahab) — Sat, 06 Dec 2025 20:36:57 +0000

The story behind the evolution of my Financial Calculator software — from a simple internship project in Iran to a fully international product!

The original project was created for an "E-Business" course and was later registered as "Basic Financial Calculator". That’s why the “0” in this video actually represents two separate early versions.

https://youtu.be/-R3erbO9yr4

Since its inception in 2011, the Financial Calculator has grown through multiple versions, each adding new features, languages, and improved interfaces. Below is a timeline of its development, highlighting key milestones and enhancements.

Development Timeline:

2011 (Initial Prototype): Developed as a university internship project in C#, originally named Basic Financial Calculator (in Persian). It included 8 sections and was released publicly as a free tool.

2014 (Version 1): Rewritten in Object Pascal, available only in English, and expanded to 10 sections for broader functionality.

2015 (Version 2): Redeveloped in Java, supporting both English and Persian, with 11 sections and built-in language translation features.

2015 (Version 3): Released with minor updates to Version 2, improving stability.

2016 (Version 4): Introduced a modern JavaFX interface for enhanced visuals and user experience.

2018 (Version 5): Released early 2018 with the JavaFX interface, refining existing features.

2018 (Version 6): Released late 2018, fixing all prior issues and remaining in use until 2025.

2025 (Version 7): Released in late 2025, rebuilt in Python, and expanded to include 16 sections.

Key improvements include:

Introduction of new sections: Barcode, Building, Invoice, Password, and QR Code, providing broader functionality.
More accurate calculations, eliminating previous logic errors.
Visual Reports for displaying data trends across sections.
Text Reports exportable in multiple formats, including PDF and RTF.
Smart Number Grouping, automatically inserting commas while typing.
Support for multiple numeral systems, such as English and Persian digits.
Full appearance customization, including color schemes and font type.
Improved database performance and an expanded feature set.
Runs independently without requiring any additional software.
In-app purchase support through cryptocurrencies.
