I don’t believe your analysis is relevant because the tread is about whether or not Blendco detergent cost is out of this world for in-bay (Vector) not a conveyor tunnel.
“Basic Tunnel wash may include pre soak,
Soap, Wheel Cleaner and drying agent. Let's say you save 5 Cents each or 20 cents per car and you charge $3.00 for a basic wash and wash 100K cars a year.” “Save 20 cents per car and the $20K falls directly to the bottom line.”
This is biased. Start at the beginning. 100K CPY * $3.00 = $300K
Say, cost of goods is
credit card fees of $500 and chemical. Chemical is $0.10 per application or $0.40 per wash or total $40,000. Other expense is $45,000. Labor burden is $75,000. Property tax is $17,000.
This leaves net operating income of $122,500. Mortgage is $100,000.
Difference is EBTD of $22,500.
So, even if you scrimp and manage to add $20,000 to bottom line, the business still sucks!
“In other words, it’s easier to make more money by seeking a higher price than trying to find fractional savings in cost.”
By seeking a higher price, I am referring to the notion of applying
marketing principals to sell more value added to customers, not just raising price in a vacuum.
