Considerable interest exists in examining per acre costs for grain farms of different sizes. Herein data from grain farms enrolled in Illinois Farm Business Farm Management are examined to determine per acre costs of farms of different size, breaking down those costs into non-land and land components.
Only financial costs are included in this study, opportunity costs for unpaid labor, management, and equity are not included. Average non-land costs do not vary across farms of different size. Land costs tend to increase with farm size.
Farms Included in the Evaluation
FBFM data for the calendar year 2011 are used to quantify per acre costs. To be included in this study, farms have to meet the following criteria:
-The farm's records have to be certified usable by FBFM field staff,
-The farm has to be located in northern and central Illinois,
-The farm has to receive the majority of income from grain operations,
-The farm has to have a high-productivity farmland,
-The farm has minimal livestock enterprises, and
-The farm has to receive less than $20 per acre in custom farming income.
-These criteria are meant to select specific farms with only grain operations so the focus is on costs from grain farm production. There were 641 farms that meet these criteria.
Non-land Costs for Different Farm Sizes
Per acre non-land costs do not vary much across farm size categories (see Table 1). Non-land costs average $484 per acre for farms with less than 500 tillable acre, $481 per acre for farms between 501 and 750 acres, $487 per acre for farms with 751 to 1000 acres, $485 per acre for farms between 1001 and 1500 acres, $480 per acre for farms between 1501 and 2000 acres, $486 per acre for farms between 2001 and 3000 acres, $477 per acre for farms between 3001 and 4000 acres, and $525 per acre for farms over 4000 acres.

Note that farms in the over 4,000-acre category have higher costs than farms in smaller size categories. The over 4,000acre farms have average costs of $525 per acre compared to smaller size categories (see Table 1). Much of the difference can be explained by higher percent of acres in corn. Farms in the over 4,000-acre category have 76% of their acres in corn while farm size categories between 1,000 and 4,000 acres are in the low-to- mid-60% range. Costs associated with corn acres tend to be higher than those for soybean acres, thereby accounting for the higher costs for farms with over 4,000 acres.
Land Costs for Different Farm Sizes
Land costs also are shown in Table 1. Land costs include the financial cost of owning land (interest on mortgage debt and property tax), share- renting farmland (equivalent cash rent on share-rent acres) and cash-renting farmland (cash rent). Note that these costs do not include opportunity costs. This is especially important on owned land. Many farms have low debt levels on owned land and hence will have low financial land costs. For example, farms without mortgage debt will only have property tax costs on owned land, roughly $30 per acre. Including an opportunity charge on owned land would increase the costs shown in Table 1.
Non-land costs increase as farm size increases. Land costs are $119 per acre for farms with less than 500 tillable acres, $157 per acre for 501 to 750 acres, $186 per acre for farms with 751 to 1000 acres, $195 per acre for 1001 to 1,500 acres, $199 per acre for 1,501 to 2,000 acres, $200 per acre for 2,001 to 3,000 acres, $191 per acre for 3,001 to 4,000 acre farms, and $234 per acre for farms with over 4,000 acres.
Farms below 1,000 acres have the lowest land costs of all farm size categories, with non-land costs below $200 per acre. These farms have low costs because more of their farmland is owned, likely at low debt levels. Farm size categories below 1,000 acres have more than 25% of their acres owned, compared to less than 20% for the larger size categories.
Farms between 1,000 and 4,000 acres have non-land costs between $186 per acre and $200 per acre. These farms have roughly 70% of their acres cash rented, with average cash rents ranging from $206 per acre up to $242 per acre.
Farms with over 4,000 acres have higher non-land costs than farms with smaller farm sizes: $234 per acre for the over 4,000-acre category compared to $200 per acre or less for the lower farm sizes. This occurs because a larger portion of farmland is cash-rented (77% for over 4,000-acre farms compared to 71% or less for lower farm sizes) and cash rents are higher for farms with over 4,000 acres ($276 per acre for over 4,000-acre farms while smaller categories average $241 per acre or less).
