Mounting Inventory Risks Profit Erosion



  • Compact and subcompact tractor supply levels have ballooned. Combines are not far behind and now larger tractors may be following suit.
  • Tracking important inventory metrics can help control holding costs before they erode a significant portion of your dealership’s profits.
  • Understanding the components of holding costs allows a dealership to know which levers to pull to control their costs.
  • Read how other dealerships are tracking and managing their inventory to reduce risky inventory and improve margin and turns.

The Inventory Challenge

First compact and subcompact tractors. Then combines. Now our Tractor Zoom data is starting to show a similarly alarming trend of growing months of supply of row crop tractors. Granted, increasing the supply year over year based on 2021 and 2022 supplies is a low bar. Some dealerships went over a year without any appreciable inventory on their lot. Now, as most major commodities plunge below profitability levels while at the same time equipment supply returns to the market, there is reason to sit up and pay attention to the growing risk of inventory holding costs.

Holding costs are not typically the top financial metric reviewed at any business. Do you know the number of business leaders I have worked with who started the feel-good portion of a meeting with what is eating away at their bottom line? Zilch. No, they start with the top-line revenue growth. It makes everyone feel good. That’s why it’s on the top line! But I have had a few who placed holding costs on our top 5 KPI scorecard. Those leaders were one of the two reasons why, during my tenure as an operations management professor, I drilled this metric into my students. The other reason is because it is vital to financial success for asset-carrying businesses in a flat or down market!

One reason holding cost is not often emphasized is because it can be ambiguous to measure. If your dealership truly wants to capture the full cost of holding your inventory, you can include:

  • Capital Costs. This includes the most obvious interest expense, but also covers the opportunity cost of what else you could be doing with your money.
  • Storage. Even if you currently have plenty of room on your lot, you are still insuring all your equipment, right? Is it depreciating? Do you have to spend money on having your crew move it around and maintain it? What about stocking parts? All of this wraps into your storage costs.
  • Service. Taxes and insurance are the most common examples of inventory services costs.
  • Risk. The more assets you have on your lot, the more you are at risk of losing something. Whether it is theft (shrink), depreciation, or worse… it becomes obsolete! More than likely obsolescence isn’t going to happen immediately, but just think of the rate of new technology being introduced. How long will it take for a farmer to look past your older model because it doesn’t have that new shiny feature? As far as depreciation goes, our Tractor Zoom analysis shows that usage, typically in hours, is the largest depreciating factor. Age is second.

Not all equipment is the same, I get it. You can throw a rock picker out in the back lot for a year and not cover it with insurance, it’s not going to be one-upped by a new model anytime soon, and a numbskull is not going to drive off with it (hopefully?). That is why calculating your holding costs by category is vital. Some categories, like those with drivetrains and tech, are going to have a much higher holding cost as a percentage of their value.

Inventory Trends and Costs

Let’s start with what we know. Smaller tractors, like every other equipment category, were backlogged all the way from the chip manufacturers overseas, to the ports off California, to the mess that was our trucking industry, to the labor constrained manufacturing floor. Calling it a mess is putting it lightly. But humans are great problem solvers, and smaller problems are easier to solve than bigger problems. Plus, add a carrot in front of small tractor manufacturers in the form of huge pandemic-inflamed hobbyist demand, and it is not hard to see why so many manufacturers prioritized pumping out tractors with less than 100 horsepower. The big problem here was that there was such a massive immediate demand that coincided with a mounting production rate behind a pinched off pipe. When that pinched pipe was released this past year, truckloads of tractors flooded the market. There likely wasn’t going to be enough demand to soak them all up anyway, but when you add significantly higher interest rates to this concoction, demand starts to look like attendance in my 8 AM Friday morning classes.

Subcompact and Compact Tractors

So what does this small tractor segment look like?


Hank Mandsager, our data scientist here at Tractor Zoom, recently analyzed the value of equipment across 39 dealerships who have been partnering with Tractor Zoom since 2021. It is important to use this consistent subset of data to control variability from the growth of new dealerships listing on Tractor Zoom since then. The holding value represents the sum of the list price for each dealership, then averaged across all 39 dealers. These dealers cover 40 states yet have a significant presence in the Midwest.

The trend is consistent across the board for subcompact and compact tractors alike at these dealerships. Average dealerships’ inventory values are drifting towards a 100% increase for these tractors in one year’s time.


Combines are highly seasonal and were not nearly as easy to ramp up production at the manufacturers as subcompacts were. Plus combine customers are almost entirely different buyers.  Farmers typically make purchase decisions with ROI in mind. Yet farmers are still being pinched by high interest rates just like acreage owners. While acreage owners are being forced to trade their tractor seats for office chairs, grain farmers have the current pressure that is the crumbling commodity markets. At the time of this writing, corn is $2 off its high and wheat can only be described as a head spinning spiral between bad and horrid. Below you can see the change in average holding value of combines at a dealership across the same 39 dealerships in this study.

Class 8 combines certainly stand out here. It’s not just that they are selling slower than other sizes, or that they are higher value machines, or that their supply is growing faster. It’s the combination of all those factors. Class 8s are one of the riskiest categories right now. If your dealership is not located near the Midwest, your inventory is likely lighter on these harvesters. Yet notice how 7s and 9/10s have still doubled in holding value over the past year. That million-dollar average increase still translates into an appreciable amount of holding cost expense which we’ll cover in a later section.

Row Crop Tractors

Not all dealerships are carrying a scary level of combines and other dealerships do not have a significant proportion of compact tractors. Yet row crop tractors do typically make up a weighty amount of the total assets at many dealerships. Supply has not returned to this category as fast as the others mentioned above, but the data is pointing in that direction.

The holding value has approximately doubled over the past year. No metric should be considered in isolation and without context. So here is that context. New supply is still moving off the lots at a decent clip. There has been, and still is, backed-up demand from farmers, and that shows when we analyze Tractor Zoom’s data, within our Iron Comps platform, to determine the growth of Months of Supply.  Months of Supply was simply calculated by dividing the current inventory advertised by that month’s sales volume.

Last April the average Months of Supply of row crop tractors was three months. After peaking at almost five months last summer and dipping in December, it is back up to four months of supply this April, an increase of 33%.  So an increasing trend, but not to the extent of combines or smaller tractors. Yet?

How much does inventory holding value actually matter?

Starting with capital costs, no one can argue with the reality of interest rates right now. Assume you can finance your equipment at 7% interest. For an opportunity cost, take the current one-year CD rate at 5%. As close to stuffing your mattress and sleeping on your money as you can get. These two bring your capital costs to 12%. (If you don’t prescribe to this opportunity cost, hold on. I’ll get to this a little later)

1.5% is estimated for taxes and insurance, although taxes are dependent on your state’s laws. The storage space costs are variable from dealership to dealership. One good way to make an estimation here is to look at your books and ask “What costs would be eliminated if you carried no inventory?” and “What costs would be cut in half if you cut your inventory levels in half?” The answers here should provide a good indication of your storage space percentages. While upside down the last couple of years, depreciation is directly correlated with inventory value, and will start to play its typical tune going forward.

Finally ‘Obsolescence’. This will take the form of a price decline, which is different from depreciation which drops with usage. Obsolescence takes place with time, not hours in the field. Take a look at your inventory. If a good portion has a chip in it, then 4% might be too low. Some may think that good ole’ iron will rust away before it becomes obsolete, and for the most part they are correct… although there are always exceptions…

Calculating Holding Costs

For every $10 million in annual inventory your dealership is carrying, your true holding cost could be as large as $2.5 million.

It’s understandable if your dealership is not measuring all these factors into your costs. If your dealership is established, the likelihood you are going to cash it all in for the opportunity of a CD sits down there on the decision ladder next to insane.  A conservative estimation though should still include at least the following, which still equates to over $1 million dollars.


“What gets measured, gets managed” – Peter Drucker

The first essential step is to gain consensus at your dealership about what will be used to calculate your holding cost, monitor it frequently (and automatically if possible), then make that measurement publicly available.  At some level your dealership requires inventory.  You don’t want to run into a scenario where your sales team cuts deals just to eliminate inventory. This is where category and even model-specific monitoring can be key if you are watching the market for hot spots. Some categories are less likely to accumulate holding costs than others. Equipment that is at high risk for obsolescence, depreciation, insurance, and is higher-value increase your holding costs. (Class 8 combines…?)

So how does one actually get ahead of this market? If we all could see the future, we would likely not be sitting where we are. You need visibility into how the market is performing compared to your pricing, and then an efficient process to act on those insights. While we cannot perfectly predict the future, now in the digital-age you can instantly access real-time information and respond strategically when appropriate.

Of course, almost everything is easier said than done. If you are anything like my students, adding in another system or program to check doesn’t go over well. My students struggled to adopt a new homework software system until we discovered it integrated with email. What was once ‘one more thing to check’, simply became responding to their email, which they were already adept at doing. Insights to Action is the name of the game.  At Tractor Zoom, we’ve seen the fastest adoption and best success stories for our partners come when we built solutions that focused on helping them get to decisions faster.

Whatever system you use to monitor and manage your inventory levels, make sure you are accounting for the full holding cost to your dealership, track it, and share those metrics. It will be especially important now as we enter a new phase in the ag economy.
