Gross Margin Calculator: Find What Your Blended Number Is Hiding

Your blended margin hides the product that’s dragging it down. One line at 14% in a 38% portfolio erases EUR 840K per year for a EUR 40M manufacturer. Add up to 5 product lines below to find it.

How to Read Your Results

The comparison table ranks every product line from worst to best margin. Check the worst-performing row first: it shows how many percentage points that line pulls the blended number down, and what portfolio margin would look like without it.

A low margin isn’t always a problem. A line at 18% on EUR 8M revenue may be a deliberate volume play to anchor a customer or fill factory capacity. The question isn’t whether the margin is low. It’s whether you made an active decision to accept it, or whether it drifted there while the blended number looked fine.

Key Insight: If removing your worst line would push the portfolio margin up by more than 3 points, you have a mix problem worth a pricing or discontinuation conversation this quarter.

What to Do With These Numbers

If one line is dragging significantly

Model a 5% price increase on that line only. At 18% margin, a 5% price increase adds roughly 4 points to that line’s margin assuming volume holds at 85%. Run the calculator again with adjusted figures before taking the number to a pricing meeting.

If all lines are within benchmark but blended margin is declining

The problem is mix shift, not a single bad product. Compare the revenue share of your lowest-margin lines this year versus two years ago. If they’ve grown as a share of total, that explains the drift. The fix is growth strategy, not cost cutting.

If COGS looks right but margin is still below benchmark

Check your COGS boundary. Sales commissions classified above the gross line, or freight costs absorbed into product cost, can shift the margin figure by 3-5 points without reflecting any real change in unit economics.
