USDA’s 2027 county base values, the same on every grid in the county. Protection per acre is the value times your coverage level times a productivity factor of 60 to 150: grazing at 90% and 100 is $20.52 an acre.
Example, not a recommendation: 100 acres of grazing at 90% coverage, productivity factor 100, half in April to May and half in June to July, on grid 20209, the middle of the county’s 12 grids by premium. The full premium is $342: USDA pays $174 and you pay $168, or $1.68 an acre. Run over 1951 to 2025 at 2027 rates, it would have paid in 54 of 75 years, an average of $296 a year, or $2.96 an acre. That is the past record, not a forecast, and it leaves out the administrative fee.
What each pair of months costs in Cimarron County
At 90% coverage, across the 12 grids that touch the county: the middle grid first, then the lowest and highest. The premium is the full rate per $100 of protection; USDA pays 59% at 70%, 59% at 75%, 55% at 80%, 55% at 85%, 51% at 90%. Normal is the grid’s average precipitation for those months. A year counts, of the 75 from 1951 to 2025, when the grid’s index for those months came in under 90% of normal, which is when a 90% policy pays.

The wettest pair of months here is July to August (5.26 in on the middle grid) and the driest is January to February (0.74 in). Coverage costs least in July to August and most in October to November. The months to insure are the ones when a dry spell costs you grass or hay, not the cheapest ones.

Which PRF grid is Cimarron County in?
Grids 19908, 19909, 19910, 19911, 19912, 20208, 20209, 20210, 20211, 20212, 20508, 20509 touch Cimarron County. A grid is a quarter degree of latitude by a quarter degree of longitude, about 17 miles north to south. Your grid follows from a point inside the acres you insure; type a ZIP or coordinates in the calculator to find it.
How much does PRF cost per acre in Cimarron County?
It depends on the grid, the months, the coverage level and your productivity factor. USDA’s 2027 county base value is $22.80 an acre for grazing, $124.00 for non-irrigated hay. At 90% coverage and a productivity factor of 100, grazing land is protected for $20.52 an acre, and the full premium runs $12.07 to $31.31 per $100 of protection depending on the months, on the middle grid. USDA pays 51% to 59% of the premium. In the example above, 100 acres of grazing at 90% with half in April to May and half in June to July, you pay $1.68 an acre on grid 20209. The calculator gives the figure for your acres and months.
How often has PRF paid in Cimarron County?
At 90% coverage a pair of months pays when the index comes in under 90% of normal. Over 1951 to 2025, on the middle grid, that happened in 29 to 46 of 75 years, depending on the months. Run at 2027 rates, $1 of full premium at 90% would have paid back a middle $0.88 across the county’s grids and months. That is the past record, not a forecast.
