Key idea

The reported earnings here stop above rent, and that is where the whole business is decided. A center under $600,000 of sales earns $16,692 before occupancy cost, against annual rent of $72,000 to $375,000. A center above $1.2 million earns $398,698. The distance between them is 26 more cars a day.

Units reporting174 of 233 centers, 2025
Weighted average net sales$1,068,198
Vehicles a day12 at the smallest, 38 at the largest
Earnings before rent3.8% to 23.5% of sales
  1. Earnings before rent of $16,692 fall short of even the cheapest rent estimate. Centers under $600,000 of sales against a low estimate of $6,000 a month *, 2.8 months of occupancy cost from a full year of trading.
  2. Crossing $600,000 of sales converts 43 cents of every extra dollar into earnings. $271,915 more sales turning $16,692 into $134,312 *. The sharpest step change in the whole table.
  3. Wages take 40.1% of sales at the smallest centers and 30.2% at the largest. $175,680 against $510,520, nearly ten points of margin sitting in how many cars the same crew serves.
  4. One more car a day is worth $36,495 to $43,952 a year. At each group’s own ticket across about 316 trading days *, so a single extra vehicle each day moves a small center from losing to breaking even.
  5. Ticket varies by 20% across the system and volume by 217%. $115.49 to $139.09 against 12 cars a day to 38 *.

Questions worth putting to Grease Monkey

The filing answers what it answers. These are the gaps an owner or a buyer should close directly.

  1. Is the profit figure in Item 19 before or after owner pay, and how many locations sit below it?
  2. What separates the highest-selling locations from the lowest: trade area, years open, size, or the owner?
  3. How long does a new location take to reach the average you publish, and what does the build-up look like month by month?
  4. At what level of sales do the minimum charges stop applying and the percentage take over?
  5. How many Grease Monkey locations closed, were sold, or changed hands last year, and why?

Every figure here comes from Grease Monkey Franchising. LLC’s 2026 FDD and is unaudited by us. We are unaffiliated with the brand.

If you want this done for you

What happens next

Everything above came out of a filing. Doing it on your own numbers means the books have to produce the same lines: sales, wages, occupancy, fees and what is left, by location, every month. That is the work.

  1. The call, twenty minutesYou describe the business and where the numbers are letting you down. We tell you honestly whether we can help, and what we would start with. No pitch deck.
  2. We look at the fileYou give us read access to the books as they are. We come back with what is wrong, what it will take to fix, and whether the answer is bookkeeping, controller work, or something else.
  3. A written scope and a priceWhat we do each month, what you get, the date it lands, and the fee. Agreed before anything starts, and it does not move without you agreeing it.
  4. Transition, then the first closeAccess, systems, and the opening balances. The first close lands on the date in the scope, and every one after it does too.

Averan is not a CPA firm and does not file taxes. Your CPA keeps that, and we keep the books they file from.
