🧮 How These Percentage Calculations Work
Understanding percentages is essential for everything from budgeting and shopping discounts to business and data analysis. Below, we explain how each type of percentage calculation works in simple terms, along with the formulas used.
✅ 1. What is X% of Y?
This calculation helps you find a portion of a number based on a percentage. For example, if you want to know what 15% of ₹2,000 is, this calculator will give you the answer.
🔢 Formula:
Result = (X / 100) × Y📌 Example:
What is 15% of 2000?
→ (15 / 100) × 2000 = 300
💡 Use Case: Helpful for discounts, tax, commission, interest, etc.
✅ 2. X is what percent of Y?
This helps you find what percentage one number is of another. For instance, if you scored 45 out of 60, what percentage did you get?
🔢 Formula:
Result = (X / Y) × 100📌 Example:
45 is what percent of 60?
→ (45 / 60) × 100 = 75%
💡 Use Case: Exam scores, progress tracking, comparing values.
✅ 3. Percentage Increase/Decrease from A to B
This tells you how much a value has increased or decreased in terms of percentage between two numbers.
🔢 Formula:
Result = ((New Value - Old Value) / Old Value) × 100📌 Example:
Price increased from ₹500 to ₹600
→ ((600 - 500) / 500) × 100 = 20% increase
Price dropped from ₹1000 to ₹800
→ ((800 - 1000) / 1000) × 100 = -20% → 20% decrease
💡 Use Case: Track price changes, growth, weight loss, performance, etc.
📎 Final Thoughts:
This calculator is designed to simplify percentage math — no more manual calculations or spreadsheets. Whether you're a student, professional, or everyday user, these tools help you compute real-world scenarios quickly and accurately.
