Net Income / Sales ... what does this number represent?

I have a quick question:

If I divide my Net Income by my Total Amount of Sales, what does that number represent? How would you interpret that business-wise?

Thanks in advance.

Well, that would give you the ratio of your net income to sales.

i would think the average money you make per sale

Aka your net profit margin.

That gives you your Net Profit Margin.

The percent of sales that eventually “trickle down” to your bottom line.

I knew there was a name for that. But I couldn’t remember it, so I decided to be obnoxious.
