Actual Production History (APH) or Yield Protection (YP)
This option of crop insurance insure producers against yield losses due to natural causes such as drought, excessive moisture, hail, wind, frost, insects, and disease. Select the amount of average yield you wish to insure; from 50-75 percent (in some areas to 85 percent). You also select the percent of the predicted price you want to insure; between 55 and 100 percent of the crop price established annually by RMA. If the harvest is less than the yield insured, you are paid an indemnity based on the difference. Indemnities are calculated by multiplying this difference by the insured percentage of the established price selected when crop insurance was purchased

Revenue Protection

This option of crop insurance provides revenue protection based on price and yield expectations by paying for losses below the guarantee at the higher of an early-season price or the harvest price.  Try this calculator to see how this works   click here.

Revenue Protection With Harvest Price Exclusion
 
This option insure farmers in the same manner as Revenue Protection polices, except the amount of insurance protection is based on the projected price only (the amount of insurance protection is not increased if the harvest price is greater than the projected price). If the harvested plus any appraised production multiplied by harvest price is less than the amount of insurance protection, the farmer is paid an indemnity based on the difference.
 

Group Risk Plan (GRP)
These policies use a county index as the basis for determining a loss. When the county yield for the insured crop, as determined by National Agricultural Statistics Service (NASS), falls below the trigger level chosen by the farmer, an indemnity is paid. Payments are not based on the individual farmer's loss records. Yield levels are available for up to 90 percent of the expected county yield. GRP protection involves less paperwork and costs less than the farm-level coverage described above. However, individual crop losses may not be covered if the county yield does not suffer a similar level of loss. This insurance is most often selected by farmers whose crop losses typically follow the county pattern

Group Risk Income Protection (GRIP)
Makes indemnity payments only when the average county revenue for the insured crop falls below the revenue chosen by the farmer.
