Knowing how to calculate percentage difference in Excel is a skill everyone needs; whether you’re managing a budget, comparing grades, or analyzing sales data. The best part? It’s way easier than it sounds, and we’ll walk you through it with examples, shortcuts, and fun analogies!
Whether you’re a student, entrepreneur, or someone trying to track expenses, understanding percentage change helps you make smart decisions.
🧮 What Is Percentage Difference?
In simple terms, percentage difference compares the difference between two numbers, showing how much one value has increased or decreased in relation to the original.
Here’s the formula we’ll use in Excel:
Formula: (New Value - Old Value) / ABS(Old Value) x 100
Let’s break it down!
Step-by-Step: How to Calculate Percentage Difference in Excel
✏️ Example 1: Sales Comparison
Let’s say you’re comparing last month’s sales to this month.
| Month | Sales |
|---|---|
| January | $1,200 |
| February | $1,500 |
In Excel, you’d type:
sql=(B2-B1)/ABS(B1) x 100
🔍 This formula subtracts the older value from the newer one, divides by the absolute value of the old number (to avoid negative math confusion), and multiplies by 100 to get a percentage.
Result:
25% → meaning sales increased by 25% in February.
✏️ Example 2: Grade Improvement
Let’s say your grade went from 60 to 75.
| Test | Score |
|---|---|
| Test 1 | 60 |
| Test 2 | 75 |
Formula: sql=(B2-B1)/ABS(B1) x 100
Result:
25% improvement in performance 🎉
When to Use Percentage Difference vs. Percentage Change
Both are used interchangeably, but technically:
- Percentage Change shows movement from one value to another (e.g., sales up or down).
- Percentage Difference compares two numbers without defining a base value (like price comparison).
In Excel, the formula works the same; it’s how you interpret the result that varies.
