Percentage Calculator
Calculate any percentage in four different ways instantly, including a bill-splitting tip calculator.
About Percentage Calculator
Percentages are used everywhere — from discounts to statistics, grades to finance. Our Percentage Calculator offers four calculation modes. Mode 1 calculates X% of Y (e.g., 20% of 250 = 50). Mode 2 calculates what percentage X is of Y (e.g., 50 out of 250 = 20%). Mode 3 calculates the percentage change between two values — useful for tracking growth, discounts, or any change over time. Mode 4 is a tip calculator: enter the bill, a tip percentage, and how many people are splitting it, to get the tip amount, total, and the exact amount each person owes. All calculations are instant with a clear, easy-to-read result.
Frequently Asked Questions
Use Mode 1: Enter the discount percentage and the original price. For example, 15% of 1000 = 150, meaning you save ₹150.
Use Mode 3: Enter the original value as "From" and the new value as "To". A positive result means increase, negative means decrease.
Percentage change = ((New Value - Old Value) / |Old Value|) × 100. It tells you by how much a value has grown or shrunk.
Yes! Use Mode 2: enter your score as X and total marks as Y to get your percentage score.
It adds your tip percentage to the bill to get the total, then divides that total evenly by the number of people — showing both the per-person total and the per-person tip alone.
Division by zero is undefined. The tool will show 0% if the denominator is zero.
