This page explains exactly how Visual Percentage Calculator works — what runs locally in your browser,
how percentage computations are handled, and what technologies power the site.
We aim for full transparency to ensure user trust, accuracy, and educational clarity.
Privacy at a glance: All percentage calculations occur directly in your browser.
We DO NOT store, log, or send your inputs or results to any external server.
1) Core Calculation Logic
Purpose: Computes a wide range of percentage operations — including
percentage increase or decrease, finding what percentage one number is of another,
converting fractions to percentages, and calculating reverse percentages.
It is designed to serve students, teachers, and professionals who require
instant and precise percentage computations.
Note: All logic is implemented natively for precision and speed without using
any external math or statistical libraries.
1.1 Implementation Summary
- Each percentage operation is handled through optimized C# arithmetic functions.
- Supports addition, subtraction, and reverse percentage calculations for both integer and decimal values.
- Rounding and decimal precision are handled consistently to ensure accurate results for all input sizes.
- No external math or visualization libraries are used — all calculations are performed using .NET’s native capabilities.
2) Percentage Calculations
- Compute what percentage one number is of another.
- Find percentage increase or decrease between two values.
- Perform reverse calculations — find the base number when a percentage and result are known.
- Determine how much a value represents as a percentage of a total.
3) Visualization Methodology
Once calculations are completed, results are displayed using clean, interactive, and responsive
HTML and CSS visuals. The percentage output is represented textually and visually through
progress bars and formatted highlights to improve comprehension. No third-party libraries or frameworks
are used for rendering or computation. This lightweight design ensures compatibility across
all browsers and devices while maintaining high speed and accuracy.
4) Application Stack
Frontend: ASP.NET (Web Forms), HTML5, CSS3, JavaScript
Language: C#
Database: Microsoft SQL Server
Target Framework: .NET Framework
Note: No user-entered data or results are stored on the server.
5) Accessibility & UX Notes
- Input fields allow users to enter numbers, percentages, and reference values intuitively.
- High-contrast color schemes and clear percentage bars enhance visual understanding.
- The calculator is fully responsive and optimized for accessibility, ensuring usability on all screen sizes and devices.
6) Security & Integrity
- All percentage computations and interactions occur locally in the browser — ensuring full data privacy.
- No cookies, local storage, or tracking analytics are linked to user input or output data.
