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 $7.83 an acre.
Example: the calculator opens on April to May and June to July, and this county does not offer both for grazing, so no example is priced here. The calculator prices the months it does offer.
What each pair of months costs in San Diego County
At 90% coverage, across the 26 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 January to February (5.33 in on the middle grid) and the driest is June to July (0.17 in). Coverage costs least in January to February and most in April to May. The months to insure are the ones when a dry spell costs you grass or hay, not the cheapest ones.

The index for each pair of months as a percent of normal (100 is a normal year), on the middle grid (each grid has its own; the calculator shows yours). Shaded cells came in under 90%, where a 90% policy on those months would have paid. 2026 shows the 6 pairs of months USDA has published so far.

Which PRF grid is San Diego County in?
Grids 15052, 15053, 15054, 15055, 15056, 15351, 15352, 15353, 15354, 15355, 15356, 15651, 15652, 15653, 15654, 15655, 15656, 15950, 15951, 15952, 15953, 15954, 15955, 15956, 16250, 16251 touch San Diego 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 San Diego County?
It depends on the grid, the months, the coverage level and your productivity factor. USDA’s 2027 county base value is $8.70 an acre for grazing. At 90% coverage and a productivity factor of 100, grazing land is protected for $7.83 an acre, and the full premium runs $28.53 to $37.32 per $100 of protection depending on the months, on the middle grid. USDA pays 51% to 59% of the premium. The calculator gives the figure for your acres and months.
How often has PRF paid in San Diego 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 39 to 43 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.
