How to Use the Percentage Calculator
This calculator has three modes. Select the one that matches your question:
Mode 1: What is X% of Y?
Formula: Result = (X ÷ 100) × Y
What is 20% of ₹5,000?
= (20 ÷ 100) × 5000 = ₹1,000
Mode 2: X is what % of Y?
Formula: Percentage = (X ÷ Y) × 100
350 is what % of 1,400?
= (350 ÷ 1400) × 100 = 25%
Mode 3: Percentage Change
Formula: Change = ((New − Original) ÷ |Original|) × 100
Price changed from ₹800 to ₹1,000:
= ((1000 − 800) ÷ 800) × 100 = +25% Increase
