Estimate your crop insurance revenue guarantee, total liability, premium cost, and the amount you actually pay after premium subsidy. This calculator helps you compare coverage levels and understand your indemnity trigger — the yield below which an insurance payment is triggered.
Select your crop, enter APH yield, projected price, coverage level (50-85%), insured acres, premium rate, and premium subsidy percentage. The calculator computes guarantee per acre, total liability, total premium, farmer-paid premium, and the trigger yield.
Guarantee per Acre ($) = APH Yield × Coverage% × Projected Price
The guarantee is the revenue level protected by the policy. For Revenue Protection (RP) policies, the guarantee may increase if the harvest price is higher than the projected price.
Total Liability = Guarantee per Acre × Insured Acres
Total Premium = Total Liability × Premium Rate%
Farmer-Paid Premium = Total Premium × (1 − Subsidy%)
The federal government subsidizes a portion of crop insurance premiums, ranging from 38% at 85% coverage to 100% for catastrophic (CAT) coverage at 50%.
Trigger Yield = APH × Coverage%
If actual yield falls below the trigger yield (for yield-based policies), an indemnity is paid.
Corn with APH of 170 bu/acre, $4.50 projected price, 75% coverage: Guarantee = 170 × 0.75 × 4.50 = $573.75/acre. On 100 acres: Liability = $57,375.
At 3% premium rate: Total premium = 57,375 × 0.03 = $1,721. With 59% subsidy: Farmer pays = 1,721 × 0.41 = $706 ($7.06/acre). Trigger yield = 170 × 0.75 = 127.5 bu/acre — yields below this trigger an indemnity.
1. Select your crop type. 2. Enter your Actual Production History (APH) yield — typically a 4-10 year average approved by the insurance provider. 3. Enter the projected price (set by RMA before planting). 4. Choose coverage level (50-85% in 5% increments; higher coverage = higher premium). 5. Enter insured acres. 6. Enter the premium rate from your insurance quote (varies by county, crop, and practice). 7. Enter the premium subsidy percentage (varies by coverage level). Click Calculate.
Federal crop insurance is a key risk management tool for US farmers, administered by the USDA Risk Management Agency (RMA). The two most common policies are Yield Protection (YP) and Revenue Protection (RP). RP protects against revenue loss from both low yields and price declines, while YP only protects against yield shortfalls. Premium subsidies are set by Congress and vary by coverage level — higher coverage levels receive lower subsidy percentages. Understanding your guarantee and trigger yield helps you make informed decisions about coverage level and marketing strategies.
Common mistakes: Confusing Yield Protection with Revenue Protection — RP includes a price component that YP doesn't. Using a single-year yield instead of the approved APH (which is a multi-year average). Forgetting that premium rates vary significantly by county — rates in high-risk areas can be 2-3× higher. Not accounting for the harvest price option in RP policies, which can increase the guarantee if prices rise during the growing season.
