Why Cost Analysis?
February 2007
You may be asking yourself; “Why do I care about cost
analysis. I don’t place government contracts where a cost breakdown analysis is
required. The seller’s bottom line price is all I need to know.”
You have a good point. It would be very nice to only
have to worry about the final price; but consider these examples:
- The seller calls to say that because of a 10%
world-wide price increase for copper, the selling price of the valve must be
raised by 10%
- The seller announces that his utility company has
raised electric rates by 10% because of a water shortage and so all of his
selling prices are being raised by 10%.
- Your maintenance manager decides that he does not
need the $10 gasket and the seller agrees to reduce the selling price by
$10.
- You agree to accept the valve unassembled so your
inspectors don’t have to take it apart to inspect on receipt. The seller
claims that will result in 1 less hour of labor at $9.00 per hour and so
reduces the selling price by $9.00.
- You have a chance to back-haul the shipment from
the seller’s plant on one of your trucks. In exchange the seller agrees to
reduce the selling price by $175 – the actual cost of commercial
transportation.
- Because you are in the food service business,
sellers are required to use very expensive food-grade grease that is only
available in 5-gallon pails. The seller raised the price of his normal
roller assembly by the value of a 5-gallon pail of the special grease.
- The seller calls one week before the valve is due
to ship and says in order to make the delivery schedule he will need 4-hours
of overtime for the shop to rework a defective casting.
True, you may not have to prepare a cost breakdown
analysis before awarding your order – but in each of these real life situations,
the more you know about the seller’s cost, the better.
Using the above scenarios, here are a few reasons why
knowing the cost breakdown might help:
- Sure, the price of copper may have risen 10%. But
the copper part of our valve is only a small percentage of the total price.
You know that the seller adds indirect overhead costs on top of the copper
material, plus G&A, plus profit. Thus, if the copper part is only worth $10
then you only want to agree to a $1 increase not a 10% increase to the
whole selling price.
- Utility costs are generally included in G&A
expenses and added to the selling price. But Utility costs are only a piece
of the G&A adder. So even if it might be appropriate to pass along the whole
utility price increase (and it might not be for a lot of reasons) the 10%
increase should only be allocated based on the net change to G&A. example:
utility costs are $500 (per year) and other G&A expenses are $500 so a 10%
net change to utility costs means that the total G&A pool rises to $1050
(only a 5% increase to the pool).
- A $10 gasket has been incremented by overhead, G&A
and profit adders and could be worth $13 by the time it gets to the bottom
line.
- Obviously – requesting that the valve not be
assembled will save some amount of labor – but how much time is that per
valve? Is it just assembly, or does it also affect time for cleaning,
testing and packaging. Don’t forget that labor charges will have an
indirect overhead component added, plus G&A plus profit. So even if we save
an entire hour of time, the time is worth much more than just the direct
wages of the laborer.
- Is the commercial transportation a separate adder
on top of all the other components of the selling price? If so, it’s easy to
compare with other transportation options if you know how much the
transportation was quoted in the first place.
- Sometimes it just makes sense to supply a
specialty commodity to the seller instead of paying the seller to procure it
on his own. In this situation we end up paying for a lot of wasted grease
(plus cost adders). Our option is to supply the seller with a small amount
of grease to use on the job and cut the grease expense completely out of the
price.
- Casting defects happen all the time and generally
allowances are made as part of a normal casting process. Was there a backup
casting poured? Is there already rework time and labor allowances included
in the price? Even if not, the casting defect should have been discovered
early in the production process not at the last minute. Also we'd want to
know which labor category has to work overtime because some are paid at
different rates.
Have I convinced you that in some cases it would be
helpful to have a cost breakdown of a seller's proposal even if it wasn't needed
it to satisfy a procedure? Having the cost breakdown - or at least a
good idea of the process and cost adders can open a lot of doors in a
negotiation. Process knowledge can also help spot delays and impacts to the job
much earlier - when corrective action will be more helpful. Understanding the
cost breakdown will also help us correctly identify impact of price increases or
specification changes.
IMPORTANT NOTE: It is much easier to find out what a seller’s true production
expenses are before you place an order. I consider Fact Finding before placing
an order mandatory – it’s not an optional exercise. The more you know before you
buy - the better. We'll talk more about fact finding later.
