Visual Percentage Calculator helps students, teachers, parents, and professionals understand percentages by seeing them. No sign-up, no paywall—just clear visuals that turn everyday percentage problems into step-by-step, trustworthy solutions.
Who we are
VisualPercentageCalculator.com is owned by and is the brainchild of Sonali Khandelwal, and it is developed and maintained by
Softusvista.
Sonali holds an MBA in Finance and Marketing and has hands-on experience in accounting, reconciliations, receivables and payables, plus volunteer work as an IRS-certified tax preparer. That grounding in numbers, accuracy, and real-world problem solving informs how this calculator is designed, verified, and improved.
Sonali’s approach emphasizes clarity and interactivity, allowing users to see percentages in action with step-by-step visuals. Whether it’s calculating discounts, profit margins, or percentage changes, the platform turns abstract numbers into tangible insights, helping students, professionals, and everyday users grasp concepts quickly and confidently.
Beyond her professional expertise, Sonali is passionate about financial literacy and educational technology. She believes in bridging the gap between numerical theory and practical understanding, empowering users to make informed decisions with numbers. Under her guidance, VisualPercentageCalculator.com combines accuracy, usability, and transparency, ensuring calculations are reliable, instant, and easy to follow.
How the idea started
The spark came at home while Sonali was helping her elder child with elementary mathematics—especially discounts, test scores, and percentage increase/decrease. After trying multiple visual approaches that could work across all common percentage tasks, she arrived at a clear, consistent visual pattern that lets learners see the structure of a problem before they compute the answer.
What makes this calculator different (our USP)
- One consistent visual language: Bars, grids, and number-line cues make “part–whole–percent” relationships obvious across all problem types.
- Concept first, steps next: Visuals build intuition; annotated steps make procedures stick.
- Classroom-ready outputs: Clean diagrams and intermediate steps are easy to project, print, or screenshot.
- Real-life coverage: From sale discounts and taxes to percent change, markups/markdowns, and growth rates—presented with worked examples.
- Bridges between forms: Smooth conversion among percent, fraction, and decimal so learners see how representations connect.
- Learner-first design: Lightweight, fast, and distraction-free so focus stays on understanding.
What it covers (core capabilities)
Sonali started with the basic Percentage of Number Calculator (and a few others). She shared the early versions with her kids’ friend circle and their parents. Based on their feedback, she realized the same visual-first concept could be extended to many aspects of percentage math with a consistent design language.
