If you’re working in Excel and need to represent change or difference in values — like growth, variation, or trends — you’ll often need to use the delta symbol (Δ) 🔺. In mathematics and data analysis, delta means “change”, and Excel gives you multiple ways to insert it. Whether you’re on Windows, macOS, or Ubuntu/Linux, this post will show you how to insert the delta symbol in Excel, along with useful keyboard shortcuts and pro tips 💡.
🔺 What Is the Delta Symbol Used For in Excel?
The delta symbol (Δ) typically represents:
- 📈 Change in values (e.g., ΔRevenue, ΔPrice)
- 📉 Difference between two numbers
- 💹 Percentage increase or decrease
Using delta in Excel can enhance the clarity of dashboards, KPIs, and reports — especially when paired with conditional formatting or arrow symbols.
✅ Method 1: Insert Delta Symbol Using Keyboard Shortcuts
| Platform | Shortcut/Method | Output |
|---|---|---|
| Windows | Alt + 30 (on numeric keypad) | ▲ |
| macOS | Option + J or use Emoji & Symbols panel | Δ or ▲ |
| Ubuntu/Linux | Ctrl + Shift + U, then type 0394, press Enter | Δ |
💡 Alt + 30 gives you the upwards arrow (▲) often used as a delta symbol. For the Greek capital delta (Δ), use the Symbol dialog or Unicode method.
✅ Method 2: Insert Delta via Excel’s Symbol Menu
- Click the cell where you want to insert Δ
- Go to Insert > Symbol
- In the Symbol window:
- Set Font to “Symbol” or “Arial Unicode MS”
- Find and select Greek Capital Letter Delta (Δ)
- Click Insert, then Close
✅ Delta symbol will now appear in the selected cell!
✅ Method 3: Use the UNICHAR Function in Excel
If you want to insert Δ using a formula:
=UNICHAR(916)
✅ Returns: Δ
🔁 For the upward triangle:
=UNICHAR(9650)
✅ Returns: ▲
This is useful in dashboards or when generating dynamic symbols with formulas.
🧩 Bonus: Custom Conditional Formatting with Δ
Use conditional formatting + delta symbol to create visual indicators:
- Use a formula like
=B2>A2 - Apply format: insert
"▲"or"Δ"with green color - Add a second rule for
=B2<A2and use"▼"with red color
🎯 Helps quickly spot trends, increases, or decreases visually.
