Wrap cast vinyl $0.97 per square foot - $1.02 per square foot. Add 15% for waste (leading edge, no one prints all the way to the edge...) and you are at about $1.15. Now add ink cost - let's say $0.30. So $1.45 per square foot pure material cost without laminate or labor, overhead, depreciation, or profit. The old rule is 25% material cost, 25% labor, 25% overhead etc., 25% profit. In this case we would be talking $5.80 as a fair price.
Intermediate wrap vinyl $0.43 per square foot. Add 15% and you are at $0.50. Add ink - let's say $0.30. So $0.80 pure material cost without laminate. 25% rule and we are at $3.20 per square foot as a fair price.
But notice profit goes from $1.45 per square foot to $0.80 = a $0.65 per square foot difference.
The job also brings in the same percentage less for labor, overhead and depreciation so $1.30 less on those as well total. Total difference in profit and expenses is $1.95 per square foot. ($4.35 per square foot for profit, labor, overhead - compared to $2.40 for same... material cost removed.) So just comparing Premium versus Intremediate material, the contribution to expenses and profits drops by almost 50%...
Now if you do the job at $2.72 per square foot, you are dropping $0.48 per square foot. Your material, labor and overhead are the same, so it must come out of profit. So we drop from $0.80 to $0.48 per square foot which = a profit now of $0.32 per square foot.
At 100 square feet you go from making $80 to $32 using Intermediate. If the job is down in wrap cast, even without lamination, profit would have been $145. So spending your time courting bottom dollar jobs nets you $113 less - you need 4.5 on these jobs to equal one better job.
Gino is right.
