Maybe the sheet utilisation factor should be applied?

If the design is good and no breakaways are needed, you might be able to fit 4 boards on a 18x24 and you end up with about 10% loss which boosts your price to $5.28.

Just a thought.

Thanks Joe... 

So are you saying that a 8X10 inch 4 layer board would be 320 square inches
times .015 dollars? That would be $4.80-USD per board... 
Hmmm... are we are paying too much?... or are the numbers used in the
calculation in need of some adjustment?

:)

There can never be any really hard numbers Bill, because  variables are many

and the devil is always in the details. 
 
That aside, 1.5 cents per layer square inch is a number that has popped up  
often in the past. 
 
With that as a ranging round, we might see some more accurate rounds lobbed

in landing a bit closer to the target.... ;-)
 
Kind regards, 
Joe
