Percentage Calculator — 3 Modes for Every % Problem
Percentages are everywhere — discounts, marks, salary hikes, GST, and interest rates. Our Percentage Calculator solves all three types of percentage problems instantly:
Mode 1: What is X% of a number? (e.g. What is 15% of ₹5,000?)
Mode 2: X is what percentage of Y? (e.g. 750 is what % of 5,000?)
Mode 3: What is the % change? (e.g. Salary increased from ₹50,000 to ₹60,000 — what % hike?)

How to Calculate Percentages – All Types
Our calculator handles four common percentage types:
Type 1 — What is X% of Y₹
Result = (X / 100) × Y
Example: What is 18% of ₹5,000₹ = (18/100) × 5,000 = ₹900
Type 2 — X is what % of Y₹
Percentage = (X / Y) × 100
Example: 450 is what % of 1800₹ = (450/1800) × 100 = 25%
Type 3 — Percentage Increase
% Increase = ((New Value − Old Value) / Old Value) × 100
Example: Price increased from ₹200 to ₹250: % increase = (50/200) × 100 = 25%
Type 4 — Percentage Decrease
% Decrease = ((Old Value − New Value) / Old Value) × 100
Example: Price fell from ₹500 to ₹400: % decrease = (100/500) × 100 = 20%
