Thinking About Expanding Your Shop?

by Dennis Kiyohara

Almost all shop owners who have been in this business for a considerable length of time have considered expanding or at least remodeling their shops. The desire to expand and/or remodel is usually caused by previous growth and success, but it's important that the decision to expand is carefully made. Expansion at the wrong time can create unnecessary hardship on the business. Following some very simple and basic steps will make the decision and implementation process easier and financially safer.

Are You Currently Making A Profit?
With few exceptions, expansion with the idea of turning losses into profits is a formula for disaster. It is essential that your business consistently generate profits before initiating expansion for three basic reasons:

Creating Your Plan

There are five basic steps to consider when creating a sound expansion plan:

The easiest way to illustrate these concepts is to use a sample shop, ABC Auto Repair, as an example. ABC is a 7,500-square-foot shop and is considering a 2,500-square-foot addition. The contractor estimates the completed expansion will cost $75,000. The following is ABC's current financial profile for an average month:

Monthly Percent of sales
Sales $50,000 100%
Gross profit20,000 40
Operating expenses15,00030
Net profit 5,000 10

ABC is making a profit! The bank has agreed to a $100,000 loan at 10 percent over five years. The monthly payments are $2,125 per month. To create the business case for the bank, ABC had to establish that it could attract and produce the sales and profits to repay the loan.

Business Capacity
Do you need to expand or just become more efficient? A simple test to determine the business capacity is to use sales per square foot. For ABC, $50,000 in sales divided by 7,500 square feet equals $6.67 per square foot in monthly sales. Multiply $6.67 by 12 months, and it equals $80 in sales per square foot per year. If the industry is producing an average of $78 in sales per square foot per year, then ABC is already producing more per square foot than most shops and expansion is probably the most reasonable method to increase sales. Here are current industry averages for individual shop sales:

Sales per square foot
Mechanical shops
Annual sales:
Sales per square foot
Average of all shops: $78
<$250,000 65
$250,000 to 500,000 70
$500,000 to 750,000 79
$750,000 to 1,000,000 85
>$1,000,000 89
Collision shops
Annual sales
Sales per square foot
Average of all shops $135
<$500,000 81
$500,000 to 1,000,000 127
$1,000,000 to 1,500,000 156
$1,500,000 to 2,000,000 157
>$2,000,000 163

Creating the plan

Step 1: Reason For Expansion
The ultimate objective from any expansion should be to maintain or increase profits. There are several reasons why expansion strategy is used to maintain profits:

By definition, expansion in a business sense means to increase sales and production. The expansion plans must be consistent with the sales strategy. For example, the following are some strategies to increase sales:

An expansion strategy that calls for more customer appeal might not be consistent with a strategy to reduce operating costs by providing more efficient repairs. Clearly defining the sales objectives also makes it possible to determine the sales requirements needed to pay for the expansion.

Expansion $75,000
Equipment $25,000
Total Investment $100,000
Cost of Capital 10%
Expected pay back 5 years
Monthly Payment $2,125

Step 2: Calculating Expansion Costs
Calculating the needed sales to cover your expansion plan starts with determining the incremental additional monthly costs for expansion, and for how long. For ABC, we know that their budgeted expansion expense will be $2,125 per month for five years.

Some other items to examine in determining the total cost per month for the expansion include:

To anticipate all the costs would be impossible, but it is essential to allow for contingencies.

Step 3: Reasonable Calendar Of Events During The Expansion
Remodeling and expansion is disruptive. It is important that a calendar of events be documented. Performance clauses should always be written in both contractor agreements and equipment purchase agreements. The most common complaints in most expansion projects are delays in the build-out or receiving all the equipment. Even if the expansion does not have a negative effect on business operations, delays will increase the total cost of the project. Be sure the calendar compensates for delays and attempts to anticipate the cost of potential delays.

Step 4: Benchmarks To Measure Expansion Success
The main benchmark is total sales. As mentioned before, increasing profit via expansion almost always means increasing sales. Following is a basic formula to determine the needed sales to create the required gross profit to pay for the investment (assuming you are already making a profit): Needed monthly burden divided by gross profit percent equals the required sales (monthly requirements Ö GP % = required sales). For ABC, the burden (monthly cost) is $2,125 and the gross profit is 40 percent. Therefore, $2,125 Ö 40% = $5,313 in monthly sales x 12 months = $63,750 in annual sales.

ABC, currently operating at a 40 percent gross profit and with expansion costs of $100,000 over five years at 10 percent, has to sell an additional $5,313 per month ($63,750 annually) to cover the $2,215 monthly expansion costs. However, selling less than an additional $5,313 per month would reduce ABC's cash flow, with a worst-case scenario of ABC losing $2,125 per month (if sales did not decrease below the normal $50,000 per year expected).

Note, the higher the gross profit (more profit per job), the fewer sales that will be required to pay for the investment. The following is an incremental chart for ABC:

Gross profit Additional sales required to
offset the monthly expansion cost
Percent Monthly Annually
35 % $6,071 $72,857
36 5,903 70,833
37 5,743 68,919
38 5,592 67,105
39 5,449 65,385
40 5,313 63,750
41 5,183 62,195
42 5,060 60,714
43 4,942 59,302
44 4,830 57,955
45 4,722 56,667

Anticipating the actual monthly costs can be difficult. The task is not only to know what the additional monthly payments might be, but the additional costs that expansion might cause, including additional personnel, equipment, operating costs, etc. These additional expenses should be added to the sales and production burdens.

With a gross profit of 40 percent, each additional $1,000 monthly payment or cost would require $2,500 in additional monthly sales. The following chart illustrates this formula for a $1,000 investment:

Gross profit Additional sales required to
offset each additional $1,000 cost
Percent Monthly Annually
35% $2,857 $34,286
36 2,778 33,333
37 2,703 32,432
38 2,632 31,579
39 2,564 30,769
40 2,500 30,000
41 2,439 29,268
42 2,381 28,571
43 2,326 27,907
44 2,273 27,273
45 2,222 26,667

If you decide you need to include a $1,000 advertising campaign to increase your sales, you must add $2,500 to your sales requirement. If your utility bills go up by $1,000 per month, add $2,500 to your sales requirement. If you need additional equipment and the lease payments are $1,000, add $2,500 to your sales requirement.

It is often assumed that the expansion will increase efficiency, and this can only be measured by an increase in gross profit. If the expansion increases efficiencies and the gross profit increases to 45 percent, the sales requirements will be much less.

Note that without increasing sales, if the expansion could increase the efficiencies and the gross profits, then the increase in the profits could cover the additional expansion debt of $2,125. (For the sake of simplicity in this illustration, additional interest from the loan and depreciation from the equipment were not added to the operating expense).

Sales $50,000 100%
Gross profit 22,500 45
(after increased efficiencies through expansion)
Operating expenses 15,000 30
(w/o additional interest/depreciation)
Net Profit 7,500 15

Step 5: Be Flexible
Be ready to adjust your plans because it is impossible to anticipate everything. This is an understood business principle.

In summary, making a profit before expansion gives the shop the flexibility to cover the additional expenses until enough sales and production are created to meet the financial requirements of expansion.
