Korea Agricultural Revenue Insurance Baseline & Payout Calculator

What does agricultural revenue insurance compare?

A similar harvest can produce less revenue when the market price falls.
A smaller harvest can also produce revenue above an insurance threshold when the applicable price rises.
Agricultural revenue insurance evaluates quantity and price together.
It does not automatically insure net profit after farming expenses or every won received from sales.

Farmers and family members can use it to reconcile price and yield changes or advances against a final benefit.
Have the policy, loss assessment, official price notice and payment record ready so the figures refer to the same field and benefit.
The English experience uses the same pure calculation function as the Korean page.

Keep baseline revenue separate from the sum insured

These amounts can differ because of truncation, contract changes or the confirmed normal yield.
Treating them as identical can overstate a reconciliation.
When the sum insured is smaller than baseline revenue, the payout for a given revenue shortfall is scaled by that ratio.

Do not substitute a simple average of your own recent harvests for the assessed normal yield.
The applicable terms and insurer’s assessment procedures use insured history, standard yield, planting and field conditions.
Area in direct-revenue mode records the insured scope; it is not multiplied into an already total amount.

Assessed revenue includes excluded yield loss

Adding excluded yield keeps losses from uninsured causes out of the covered revenue loss.
Its imputed revenue is not money received from a sale.
Assessed revenue can therefore exceed cash sales without being a calculation error.
A confirmed excluded yield of zero is different from an amount that has not yet been assessed.

Where quality, pests, varieties or area-weighted factors matter, obtain the final assessed inputs with those rules correctly reflected.
This calculator does not estimate crop damage from photographs or determine grades and pest losses.
Leave the final-value confirmation unchecked while a price notice or quantity verification remains pending.

Past-revenue formula and product boundaries

This rearranges the terms’ sum insured × (loss ratio − deductible ratio).
The loss ratio is (baseline revenue − assessed revenue) ÷ baseline revenue and must strictly exceed the deductible ratio.
Coverage is 100% minus the deductible: 80% coverage corresponds to a 20% deductible.
It does not mean receiving 80% of the premium back.

Use the calculator with your documents

1. Year and field: Confirm a 2026 contract, ordinary past-revenue product, crop, region and insured field area.
   The guideline’s minimum area is 1,000 m²; eligible regions and sales periods vary by crop.
   
2. Baseline and insured amount: Enter confirmed total baseline revenue or calculate it from confirmed kg/10a, area and price.
   Copy the sum insured separately from the policy.
   
3. Policy coverage: Select the actual 60%, 70%, 80% or 85% rate.
   Confirm additional 85% conditions and applicable restrictions.
   
4. Assessment and advances: Enter harvested quantity, excluded yield, final applicable price and prior payments for the same revenue benefit.
   Confirm that no termination or special adjustment applies.
   
5. Next action: Distinguish the gross benefit from the remaining payment, save the worksheet, and ask the insurer or local NH office to verify final amounts and rounding.
   

The 85% option requires the relevant participation conditions and crop eligibility under the 2026 guideline, such as yield reporting, combined-field enrollment, supply-stability programs or rice-area reduction.
It is not available to every farmer automatically.
A five-year cumulative loss ratio of at least 500% restricts selection of 80% or higher cover for products whose sales begin from July 2026.
Ask the enrolling NH office whether your contract falls within that restriction.

Worked examples with fictional quantities

The following figures illustrate the arithmetic rather than an individual entitlement.
4,000 m² × 2,500 kg/10a ÷ 1,000 × KRW 3,500/kg gives baseline revenue of KRW 35,000,000.
At the same sum insured and 80% coverage, the guaranteed threshold is KRW 28,000,000.
Hold harvested quantity at 6,000 kg and harvest price at KRW 2,500/kg while changing excluded yield and sum insured.

Price and yield thresholds indicate benefit onset

These thresholds are not forecasts or farm-profit break-even points that account for costs.
They describe a gross payout before advances, so a positive gross amount can still leave no additional payment.
If price and quantity both change, update both inputs instead of applying the original threshold unchanged.

Zero assessed quantity has no finite price threshold; zero applicable price has no finite quantity threshold.
If excluded yield alone reaches the guaranteed threshold, no harvested quantity, including zero, produces a benefit at that price.
The calculator explains these cases separately.
It compares values before rounding and displays thresholds to six decimal places.

Separate gross benefits from remaining payments

Do not combine replanting, reseeding, cultivation-failure or harvest-failure payments into the prior-payment field.
Some benefits terminate the field’s contract, so first verify whether any revenue-reduction benefit remains available.
Neither subtracting unrelated benefits to force a zero result nor ignoring termination to show an additional payment is appropriate.

When prior payments exceed the gross candidate, the remaining amount is zero and the excess is shown separately for review.
It is not a repayment determination.
Check mixed benefits, fields, seasons and special settlement conditions with the insurer.
Displayed amounts are rounded to whole KRW for reference; actual payment rounding follows the insurer’s rules.

Practical scenarios and reasons to withhold results

• Wait for final price notices and assessed harvested and excluded quantities.
  
• Review other years, expected-revenue or actual-receipt products, and areas below 1,000 m² separately.
  
• Crop-quality and pest factors, endorsements, combined-field assessments, shared cover and termination cannot be resolved by the ordinary formula alone.
  
• The coverage table compares arithmetic only.
  It does not assume identical eligibility, premiums or public subsidies and does not recommend a product.
  

This calculator does not price premiums, central or local subsidies, or next-year premium changes.
Obtain current eligibility and quotes from the insurer and local NH office.
The KRW 1 trillion, 100 million quantity or price, and four-decimal limits are technical input bounds, not statutory coverage limits.
