What Is This Tool?

This calculator helps you determine the percentage increase from an original value (A) to a new increased value (B). It simplifies the process of quantifying growth or increments in various contexts such as prices, grades, or performance metrics.

How to Use This Tool?

  • Enter the original value (A) which is the starting amount
  • Input the new value (B) which must be greater than the original value
  • Click the calculate button to see the percentage increase
  • Review the result displayed as a percentage showing how much the value has risen

Key Features

  • Calculates percentage increase using the formula: ((B - A) / A) × 100
  • Supports accurate decimal and percentage calculations with consistent floating-point precision
  • Easy input for original and new values
  • Quick results for instant analysis
  • Browser-based and user-friendly interface

Examples

  • If a product price goes from $80 to $100, the percentage increase is ((100 - 80) / 80) × 100 = 25%
  • For a grade improvement from 70 to 85, the calculator shows the increase in percentage terms for easy comparison

Common Use Cases

  • Evaluating price increases in retail or wholesale scenarios
  • Tracking performance improvements such as grades or test scores
  • Analyzing financial metrics for investments or revenue growth
  • Comparing measurements that have increased over time in scientific or business data

Tips & Best Practices

  • Ensure the new value B is greater than the original value A to get a valid percentage increase
  • Double-check inputs for accuracy to maintain precise results
  • Use consistent units when entering values to avoid confusion
  • Apply the tool for clear comparisons in reports or presentations

Limitations

  • This calculator only measures increases; it does not compute decreases in value
  • For percentage decreases, a separate calculation or different tool is required
  • Values must be numerical and B must be strictly greater than A to produce a result
