By Gary SchnitkeyDepartment of Agricultural and Consumer EconomicsUniversity of IllinoisFor farmland having an expected corn yield of 190 bushels per acre, a reasonable expectation of 2017 gross revenue is $741 per acre. Obviously, revenue will vary from the $741 expectation depending on price and yield outcomes. In this article, possible 2017 crop revenues, crop insurance payments, and Agricultural Risk Coverage (ARC) payments are evaluated using the historical price and yield changes from 1975 to 2016. The analysis uses corn yields from Logan County, Illinois. For each year, the sum of crop revenue, crop insurance payments, and ARC payments equals gross revenue. The historical analysis suggests that 2017 gross revenues can range from a low in the mid-$600 range to a high of over $900 per acre.Possible Revenues based on Historical Price and Yield ChangesPossible revenues are based on harvest prices, market year average (MYA) prices, and yields calculated given price and yield changes from 1975 to 2016. Table 1 shows harvest prices, MYA prices, and yields used in the analysis. Calculation of each price and yield are as follows:
The above procedures results in 42 price and yield combinations. Each combination represents the price and yield that would result if conditions in the respective year occurs in 2017. For example, if 1975 conditions are repeated in 2017, the harvest price would be $4.25 per bushel, the MYA price would be $3.89 per bushel, and Logan County yield would be 211 bushels per acre (see Table 1).From these prices and yields, the components of gross revenue are calculated:
Note that county yields are used in this study. Farm yields typically are more variable than county yields. AS a result, Use of farm yields would increase variability illustrated below. However, lowest revenues will not vary much from those shown here because crop insurance provide payments so that revenue does not decrease below the crop insurance guarantee.Prices and YieldsMYA prices average $3.68 per bushel over the 42 simulated years, with a low of $2.65 and a high of $5.14. Again, these prices are calculating using historical price changes occurring in the past. In 12% of the simulated cases, MYA prices are below $3.00 per bushel. Therefore, historical changes suggest a chance of very low corn prices.Logan county yield averages 190 bushels per acre over the simulated cases, with the low yield being 105 bushels per acre (occurring in a year like 2012) and the high yield being 236 bushels per acre (occurring in a year like 2014). Figure 1 shows that scatter of yields and prices for the simulated years. Each dot represents a year's yield and MYA price combination. Two of these dots are denoted by year: 2014 and 2016. These two years represent the first and third highest yield over the entire time period. Overall, yields have been high in recent years in Illinois, tempering income declines that occurred because of low prices. The historical analysis suggests continuing high yields like those in 2014 and 2016 should not be expected.As expected, higher yields generally are associated with lower prices (see Figure 1). Logan County is in the heart of the Corn Belt and high yielding years generally indicate high corn supplies, leading to lower prices. While strong, this relationship also is not certain. There are situations in which yields and prices are not as direct, particularly when yields are within 15 bushels of the 190 bushel mean. In these cases, a wide range of prices has occurred in the past, suggesting a wide range is possible in 2017 if yields are near normal.Revenue estimatesThe average crop revenue across the 42 simulated years is $691 per acre (see Table 1). The lowest crop revenue is $485 per acre and occurs in the simulated year like 2012. In this year, the yield is 105 bushels per acre and the MYA price is $4.62 per bushel. Crop revenues in the high end are slightly over $900 per acre and occur in a year like 2006. In this year, the simulated yield is 191 bushels per acre and MYA price is $4.81 per bushel. A dramatic increase in price occurred in 2006, mostly associated with the introduction of more corn use in the production of ethanol.An 85% RP policy makes payments in 43% of the simulated years. Average crop insurance payments, including the years in which RP does not make payments, is $28 per acre (see Table 1).ARC makes payments in 43% of the years, a higher percentage than many may be expecting (see Table 1). Two types of situations result in ARC payments. The first are very low-yielding years. Three years in which yields were well below trend in Logan County are 1988, 2005, and 2012. Simulated ARC payments for two of these three years are at the maximum of $66 per acre, with the other year at $54 per acre. The second type of year that results in ARC payments are when MYA prices are projected to be below $3.25 (1977, 1981, 1998, 1999, 2000, 2001, and 2008). The average ARC payment for the 42 simulated years, including years in which ARC does not make payments, is $22 per acre.Average gross revenue is $741 per acre (see Table 1). There is, however, a considerable range in possible revenues. Revenues above $850 per acre are possible and occur in six years (1987, 1988, 2007, 2007, 2010, and 2012). In all these years, MYA price is above $4.00 per bushel.There also are 35% of the years in which revenue is projected to be below $700 per acre, with the lowest revenue projected at $631 per acre. The combination of crop insurance and ARC provides a safety net so that gross revenues below $630 per acre do not occur. The red dots in Figure 1 show the yield and price combinations associated with revenue below $700 per acre. In those simulated years, yields are not exceptionally large or small, generally within 15 bushels of the expected yield of 190 bushels per acre. Prices tend to be below $3.50 per bushel.Commentary and SummaryAs always is the case before planting, there is a considerable range of possible revenues. This analysis indicates that a reasonable expectation for corn land with expected yield of 190 bushels per acre is gross revenue of $741 per acre, with a range of possible gross revenues from around $650 per acre to just over $900 per acre. Similar ranges could be found for a different farmland productivity. Adding or subtracting the difference in expected yield times $3.70 per bushel would give a ballpark range for revenues. If expected yield is 200 bushels per acre, 10 bushels higher than used here, expected revenue would increase by about $37 per acre to $778 per acre.Central Illinois budgets suggest non-land costs of $530 per acre for corn. Adding a $240 cash rent results in a total cost of $770 per acre. Average gross revenues of $741 per acre are below those costs by $29 per acre. If gross revenue occurs at the high end of the range, corn production on central Illinois farmland will be profitable. On the other hand, revenues below $700 would result in losses. The historical analysis suggests the likely most likely scenario resulting in low gross revenue is when yields are within 15 bushels of normal and prices fall below $3.40 per bushel.Actual revenues will depend on price and yield changes occurring this summer and fall. As always, planting progress, growing conditions, and demand changes will be of importance in determining revenues and incomes.
