📚 Percentage Calculation: The Complete Reference Guide

Percentages are everywhere — from store discounts and taxes to profit margins and test scores. Understanding how to calculate them accurately saves time and prevents costly mistakes. This guide explains the three essential percentage operations you'll encounter daily.

1. Finding a Percentage of a Number

Formula: Result = (Percentage ÷ 100) × Total

Example: What is 15% of 400,000?
(15 ÷ 100) × 400,000 = 60,000

This is the most common calculation — used for discounts, tips, and sales tax.

2. Reverse Percentage (What Percent One Number Is of Another)

Formula: Percentage = (Part ÷ Total) × 100

Example: 150,000 is what percent of 700,000?
(150,000 ÷ 700,000) × 100 = 21.43%

Use this to understand proportions — e.g., what portion of your budget is spent on rent.

3. Percentage Increase or Decrease

Formula: Percentage Change = ((New Value - Old Value) ÷ Old Value) × 100

Example: Sales increased from 500 to 650 units.
((650 - 500) ÷ 500) × 100 = 30% increase

Essential for tracking growth, inflation, and performance.
