Percentage Calculator — Calculate % of Any Number Instantly | Calczia

Percentages show up everywhere — your exam scores, your salary hike, shopping discounts, GST, EMI interest rates, and investment returns. And yet, calculating them quickly in your head isn't always easy. Calczia's Percentage Calculator handles all common percentage problems instantly.

3 Types of Percentage Calculations

1. What is X% of Y? — Formula: (X/100) × Y. Example: What is 15% of ₹3,500? → (15/100) × 3,500 = ₹525.
2. X is what % of Y? — Formula: (X/Y) × 100. Example: 450 marks out of 600 = (450/600) × 100 = 75%.
3. Percentage increase/decrease — Formula: ((New – Old) / Old) × 100. Example: Salary went from ₹40,000 to ₹46,000 → ((46,000 – 40,000) / 40,000) × 100 = 15% increase.

Common Percentage Problems Students Face

• Calculating exam percentage from marks obtained vs total marks
• Finding discount price after a percentage off
• Calculating what percentage of budget has been spent
• Determining percentage change in crypto prices

Calczia's calculator handles all of these with separate input fields for each type of problem, so you always pick the right formula automatically.

Percentage vs Percentile — Know the Difference

Percentage is your actual score expressed per 100. Percentile tells you what percentage of students scored below you. A 90 percentile in JEE means you scored better than 90% of candidates — not that you got 90% marks.
