Percentage Calculator Guide
What this calculator does
This tool supports four common percentage workflows: percentage of a value, increase by percentage, decrease by percentage, and percentage difference between two values. It is useful for discounts, markups, exam score analysis, budgeting, and comparing changes across two numbers without manually applying formulas each time.
How to use it
Pick a mode from the top tabs, then fill both inputs. The label text changes based on selected mode so you always know what each field means. Results refresh instantly while typing, and the badge summarizes whether the outcome is positive or negative change. Use the total row in increase/decrease modes to see the final adjusted amount.
Example usage
If the original price is ₹2,000 and discount is 15%, choose decrease mode to see discount value and final payable amount quickly. For growth tracking, if sales move from 800 to 1,000, choose difference mode to estimate percentage change and understand trend direction before reporting or planning next targets.
