Choosing a crop insurance coverage level is a trade-off between protection and out-of-pocket premium, and the federal subsidy makes that trade-off non-linear. This estimator builds the guarantee from your APH yield and price, applies your base rate, then layers in the RMA subsidy to show the net premium you actually pay at each coverage level.
How it works
The guarantee sets liability, the rate sets premium, and the subsidy reduces what the farmer pays:
guarantee/ac = APH yield × coverage level × projected price
liability = guarantee/ac × acres
total prem = liability × base rate
subsidy $ = total prem × subsidy %
farmer prem = total prem − subsidy $Subsidy percentages fall as coverage rises, so the farmer-paid premium climbs faster than coverage, which is why the highest coverage levels are not always the best value.
Illustrative example
A corn producer with a 180 bu/ac APH, a projected price of $5.00, and 320 insured acres, electing 75% Revenue Protection:
- Guarantee per acre: 180 × 0.75 × $5.00 = $675/ac
- Total liability: $675 × 320 = $216,000
- Total premium at a 0.045 base rate: $216,000 × 0.045 = $9,720
- Enterprise-unit subsidy at 75% coverage: approximately 55%
- Subsidy amount: $9,720 × 0.55 = $5,346
- Farmer-paid premium: ~$4,374
Now consider electing 85% instead. The guarantee rises to $765/ac, liability to $244,800, and total premium to roughly $11,016. But the subsidy at 85% drops to about 38%, leaving a farmer-paid premium near $6,830 — roughly 56% more out-of-pocket for 13 percentage points of additional coverage. Whether that insurance-per-dollar exchange rate is worth it depends on your financial position and marketing plan.
Understanding the subsidy structure
The federal subsidy is designed to make coverage broadly accessible while discouraging extremely high-coverage elections that carry high actuarial cost. Typical enterprise-unit subsidy percentages by coverage level (these are general illustrative ranges — confirm with your agent’s RMA worksheets):
| Coverage level | Approximate subsidy |
|---|---|
| 50–70% | ~67% of total premium |
| 75% | ~55% |
| 80% | ~48% |
| 85% | ~38% |
Because the subsidy is a percentage of total premium (not a fixed dollar amount), the absolute subsidy still rises as you move to higher coverage, but the farmer’s share rises faster.
YP vs. RP: which plan to use
Yield Protection (YP) only pays when you suffer yield loss, valued at the projected price. It does not protect against a price drop between planting and harvest. Revenue Protection (RP) pays on the higher of projected or harvest price, so a yield loss during a year of rising prices pays more, and a yield hit in a falling-price year is also covered. RP carries a higher base rate for that additional protection. Most row-crop producers elect RP for the price-floor benefit, but YP can be appropriate when you have forward contracts that lock in your price independently.
Notes and caveats
This estimator uses embedded subsidy percentages and a base rate you supply. Actual premiums depend on the county actuarial data, unit structure (basic, optional, enterprise, whole-farm), practice (irrigated vs. non-irrigated), and approved APH history. Always obtain a binding quote from a licensed crop insurance agent using official RMA actuarial documents before electing coverage.
