The Gross Profit Margin Formula

The formula for calculating gross profit margin is:

Gross Profit Margin = (Revenue – COGS) / Revenue × 100

Step-by-Step Calculation in Excel

Organize Your Data: Create columns for Revenue and COGS in your Excel sheet
Calculate Gross Profit: In a new cell, enter “=Revenue_Cell – COGS_Cell”
Calculate Margin: In another cell, enter “=(Gross_Profit_Cell/Revenue_Cell)*100”
Format as Percentage: Right-click the margin cell → Format Cells → Percentage

Paste this code:

Sub CalculateMargin()
    Dim revenue As Double, cogs As Double
    revenue = Range("B1").Value
    cogs = Range("B2").Value
    Range("B3").Value = revenue - cogs
    Range("B4").Value = (Range("B3").Value / revenue) * 100
    Range("B4").NumberFormat = "0.00%"
End Sub

Maintain consistent accounting practices
Separate COGS from operating expenses

Case Study: Retail Business

A clothing retailer with $500,000 revenue and $300,000 COGS:

Gross Profit = $200,000
Gross Margin = 40%
Action: Negotiated 5% better fabric prices → margin improved to 43%
