Iowa farmland leasing overview

Cash rent lease agreements are popular because the lease is simple, the rent is fixed and the owner is relieved of making operating and marketing decisions. Likewise, the tenant has maximum freedom to plan and develop the cropping and livestock programs. The risk and returns from changing prices, yields, and costs are all borne by the tenant.

Types of Cash Rent

A farm may be rented for a fixed amount per acre for all acres in the farm (e.g. 160 acres in a quarter section) regardless of the number or acres of cropland, pasture, buildings, or waste. This is referred to as a whole-farm rental rate. Or, the farm may be rented for a fixed amount per cropland acre (i.e., 145 acres cropland in a 160-acre farm) with a different rental rate for any pasture or buildings.

Normally, whole farm rental rates are lower than cropland rental rates because the land that is not cropped is often of lower productivity or not used. Exceptions are building sites and grain storage facilities.

Several methods for computing cropland rental rates are outlined below. A separate rental rate should be used for pasture, storage, livestock facilities. All of the rental items can be included in the same lease agreement.

Approaches for Determining a Rental Rate

Determining a fair rate is not easy. Cash rents are likely to be too low during periods of rising prices and high yields and too high during periods of declining prices and low yields. Rates often reflect the results of the past few years more than the upcoming year.

Estimating a cash rental rate for cropland can be based on:

  • what others are charging/paying
  • average yields
  • corn suitability ratings (CSR2 index)
  • share of gross crop value
  • return on investment
  • crop share equivalent
  • tenant’s residual.

What Others are Charging/Paying

The most common method of establishing a cash rent is to set a rate similar to what other people in the area are charging. ISU Extension and Outreach publication FM 1851/AgDM C2-10, Cash Rental Rates for Iowa, shows typical rental rates reported for high-, medium-, and low-quality cropland in each county in Iowa, as well as land in oats, hay, and pasture.

This method assumes that what others are charging is fair and equitable. A landowner receiving less rent per acre than the neighbors feels that he or she is not receiving what is rightfully due. However, a landowner receiving more than a neighbor may feel that he or she is being unfair to the tenant.

There are three potential pitfalls with this approach:

  • Charging what others are charging may not be appropriate for a particular farm. Remember that most other tenants and landowners are in the same position you are. They are looking for someone to tell them what rental rate is fair and equitable. If you use this method, compare your rate to many other rates instead of just one.
  • Rumors about cash rental rates may be quite different than the typical rates, especially in a rapidly changing market.
  • Differences in the quality of land should be taken into account when comparing your rental rate to those of others. Landlords who are unfamiliar with farming often assume all land is of equal productivity. So, when using this method, be sure to compare your rate to rates for land of comparable quality, based on actual yields or productivity indices.

Average Yields

A cash rental rate can be based on a farm’s average yields (e.g.,5-year or 10-year average). For example, assume the average rental rates in your county are $1.25 per bushel for corn and $4.40 per bushel for soybeans, based on the latest survey information. If your farm has an average corn yield of 160 bu. per acre this results in a rental rate of $200 ($1.25 x 160 bu. = $200) per acre. An average soybean yield of 58 bushels per acre results in a rental rate of $255 ($4.40 x 58 bu. = $255) per acre.

ISU Extension and Outreach publication FM 1851/AgDM C2-10, Cash Rental Rates for Iowa, shows rental rates per bushel of corn and soybeans by county. Remember, use a long-term average yield (both good and bad years), and don’t just pick out the good years.

Corn Suitability Ratings

The Corn Suitability Rating System (both CSR andCSR2) are farmland productivity indexes developed for property tax assessment purposes. Values range from 0 to 100, with higher numbers indicating higher land productivity.

Each soil type in Iowa has a CSR2 value. The ISU Soil and Land Use website explains CSR2 in greater detail. By identifyingthe soil types and acres of each soil type in a tract of land, the weighted average CSR2 can be calculated for the tract. AgDM Information File C2-87, Computing theCorn Suitability Rating for Your Farm, shows how to use the Web Soil Survey website from the USDA Natural Resource andConservation Service (NRCS) to find your farm’s CSR2 value. Include only the land suitable for row crop productionin the "area of interest" to find the CSR2 for row crop land.

A cropland cash rental rate can be computed by multiplyingthe average CSR2 by a rental rate per CSR2 point. For example, assume a typical rental rate per CSR2 index pointof $3 for your county. A tract of land with a CSR2 of 80 would have a rental rate of $240 ($3 × 80 CSR2 = $240)per acre. ISU Extension and Outreach publication FM 1851/AgDM C2-10, Cash Rental Rates for Iowa, shows typical rental rates per CSR2 index point by county.

Share of Gross Crop Revenue

Cash rental rates tend to follow the gross revenuegenerated from the crop being produced. Table 1 showsaverage cash rents in Iowa as a percent of the grosscrop value for the past 10 years. Gross crop value is the state average yield times the state average price fromOctober through December. Gross crop revenue is also shown, which includes gross crop value plus all USDA commodity program payments and crop insurance indemnity payments. In recent years, these values havebeen nearly identical because only direct paymentshave been received from the USDA and crop insurance payments have been small. In the earlier years, larger USDA payments were received.

These percentages and estimated yields and prices forthe coming year can be used to estimate a fair cash rental rate. Expected crop insurance payments are zero when average yields are assumed.

Return on Investment

Another method is to multiply the estimated current market value for cropland by an expected rate of return. Surveys show that cash rents for good cropland in Iowa in recent years have averaged about 3 to 4 percent of current land values.

Land value $4,000 $6,000
Rate of return 3-4% 3-4%
Rental rate $120-$160 $180-$240

Estimates of current land market values are available in ISU Extension publications AgDM C2-70, Farmland Value Survey - Iowa State University and AgDM C2-75, Farmland Value Survey - Realtor’s Land Institute. However, this method is rather imprecise, especially during periods of rapidly changing land values.

Table 1

Crop Share Equivalent

Table 2Another way of calculating cash rental rates is by comparing the rental rate to the return that would be received from a 50-50 crop-share lease. With a crop-share lease, the owner’s return is automatically adjusted by changes in yield, selling price, and input amounts and prices. However, to compute a cash rental rate using this method, estimates of yields, selling prices and input costs must be made for the coming year, which is sometimes difficult to do.

An example using this method is presented in Table 2. Use 5-year or 10-year average yields and current prices for harvest delivery. If prices are below the USDA county loan rate, use the loan rate instead, to reflect potential loan deficiency payments. You may want to refer to ISU Extension publication FM 1872a/AgDM A1-32, Commodity Programs for Crops. Then subtract the landowner’s half of the seed, fertilizer, pesticides, and other shared expenses.

In the example, the landowner will receive a net return of $213and $197from corn and soybeans respectively. With a corn/soybean rotation, the average return will be (213+ 197) / 2 = $205per acre.

Tenant’s Residual

Another approach is to calculate how much income the tenant has available for rent payments after subtracting all the tenant’s costs associated with producing the crop.

Table 3As in Table 2, you first need to estimate yields, selling prices,and other crop income received. Then subtract the operating expenses. Next, subtract the tenant’s cost of machinery and equipment ownership. This includes depreciation, a return on investment, insurance, and machinery housing. Some people contend that these costs (fixed costs) are incurred by the tenant whether the land is rented or not and need not be subtracted when determining a rental rate. But in the long run, these costs are incurred on all acres farmed and must be paid. Finally, a charge for the tenant’s labor and management is subtracted. The remaining amount is available for the payment of cash rent.

Based on the example values in Table 3, $259is available for rent payment from corn production and $279 from soybean production. With a corn/soybean rotation, the average amount available for rent payment is $269per acre.

Remember, no allowance has been made for risk due to variations in crop prices and yields. With a cash rent lease, the tenant assumes all of the risk. So the tenant should be compensated for assuming this risk. Do this by either using conservative price and yield estimates or adjusting the rental rate downward.
