How to Type the Delta Symbol in Excel
How to use Δ and δ in Excel for change, difference, math, and reporting.
When delta is useful
In spreadsheets, Δ usually means change or difference. For example, “Revenue Δ” can mean the difference between this month and last month. Lowercase δ is more common in math and science notes.
Fast insertion options
You can copy Δ directly, use Excel’s Insert → Symbol menu, or set up an AutoCorrect shortcut if you use it often. Copy-paste is quickest when you only need the symbol occasionally.
Make reports easier to read
Use delta in headings, not everywhere. A column title like “Cost Δ” is clear; filling every row with extra symbols can make a report harder to scan.

Should I use Δ or ∆?
