Actual Production History crop insurance uses a farm’s historical production records to help establish its insured yield and coverage guarantee. Commonly called APH, this system connects documented farm performance with the amount of protection available under many federal crop insurance policies.
A higher approved APH yield can increase the farm’s production or revenue guarantee. A lower approved yield can reduce that guarantee. Because the calculation affects coverage, premiums and potential indemnities, accurate production reporting is one of the most important parts of a crop insurance policy.
This guide explains how APH works, which records farmers need and how options such as Yield Adjustment, Yield Exclusion and Trend Adjustment may affect the final approved yield.

Key Takeaways
- Actual Production History, or APH, is based on historical crop production and acreage records.
- An APH database normally contains at least four and no more than ten crop-year yields.
- When fewer than four acceptable actual yields are available, transitional yields may be used.
- The approved APH yield helps determine production and revenue guarantees.
- Production generally must be reported by the applicable production reporting date.
- Missing or unsupported records can result in an assigned yield.
- APH databases may be separated by crop, unit, type, practice or other policy characteristics.
- Eligible yield options can protect the APH calculation from unusually low years or account for improving yield trends.
- Higher approved yields can increase coverage but may also affect premiums.
- Actual Production History crop insurance calculations should be reviewed with the agent every year.
1. What Is Actual Production History Crop Insurance?
Actual Production History crop insurance is not always a separate insurance plan. APH is also the historical yield system used to establish approved yields under several federal crop insurance plans.
The USDA Risk Management Agency describes an annual yield as the yield per acre entered for a crop year in an APH database. Depending on the producer’s history and policy circumstances, an annual yield may be:
- An actual yield
- A transitional yield
- An assigned yield
- Another yield calculated under approved FCIC procedures
The resulting approved yield may be used with plans such as:
- Yield Protection
- Revenue Protection
- Revenue Protection with Harvest Price Exclusion
- Certain crop-specific APH policies
- Other yield-based federal crop insurance products
For example, Revenue Protection uses the approved yield when calculating the farm’s initial revenue guarantee. Yield Protection uses it to establish the number of bushels, pounds, tons or other units protected.
You can review the differences between these plans in our guide to Revenue Protection vs. Yield Protection crop insurance.
2. How Does an APH Database Work?
An APH database is a record of annual yields associated with a particular insured crop and production arrangement.
The USDA Risk Management Agency insurance cycle states that an APH database must generally contain a minimum of four and a maximum of ten crop-year yields.
The database is updated as newer crop years become available. Once the maximum base period has been reached, the oldest yield generally drops out when a new yield is added.
This rolling structure means the approved APH yield can change every year.
APH Databases Can Be Separated
A producer does not necessarily have one APH average covering every acre on the farm. Separate databases may be required according to factors such as:
- Crop
- County
- Insurance unit
- Irrigated or non-irrigated practice
- Crop type or variety
- Production method
- Map area
- Land classification
- Policy-specific requirements
For example, irrigated corn may have a different yield history from non-irrigated corn. Combining those records without authorization could misrepresent the productive capacity of both practices.
Optional units also require acceptable separate acreage and production records. If a producer cannot support the separation, the insurer may combine acreage into a larger unit or apply other policy consequences.
3. How Is an APH Yield Calculated?
The basic concept is straightforward:
Annual yield = Total production ÷ Planted acres
The annual yields included in the database are then averaged, subject to applicable policy procedures and elected yield options.
Consider a simplified ten-year corn history:
| Crop year | Reported yield |
|---|---|
| Year 1 | 180 bu./acre |
| Year 2 | 170 bu./acre |
| Year 3 | 190 bu./acre |
| Year 4 | 160 bu./acre |
| Year 5 | 200 bu./acre |
| Year 6 | 140 bu./acre |
| Year 7 | 185 bu./acre |
| Year 8 | 175 bu./acre |
| Year 9 | 195 bu./acre |
| Year 10 | 155 bu./acre |
| Average | 175 bu./acre |
Without additional adjustments, the simple average is 175 bushels per acre.
If the producer selects a 75% coverage level:
175-bushel approved yield × 75% = 131.25-bushel production guarantee per acre
If the applicable projected price is $4.50 per bushel, a simplified Yield Protection guarantee would be:
131 bushels × $4.50 = $589.50 per acre
Actual insurance calculations may apply rounding rules, insured share, acreage, price percentages, options and crop-specific provisions.
Average Yield vs. Approved Yield
The simple historical average and the final approved APH yield are not always identical.
The approved yield can be affected by:
- Transitional yields
- Assigned yields
- Yield Adjustment
- Yield Exclusion
- Trend Adjustment
- Yield cups
- Yield floors
- Beginning farmer provisions
- New-producer procedures
- Added-land procedures
- High-variability tests
- Changes in farming practices
- Policy-specific limitations
Therefore, producers should not calculate a simple average and assume it will automatically become the official insured yield.
4. Why APH Matters for Crop Insurance Coverage
Actual Production History crop insurance calculations directly affect the size of the farm’s guarantee.
Consider two otherwise identical farms:
| Farm | Approved APH yield | Coverage level | Production guarantee |
| Farm A | 180 bu./acre | 75% | 135 bu./acre |
| Farm B | 140 bu./acre | 75% | 105 bu./acre |
Farm A receives a larger production guarantee because its approved yield is higher.
Under a revenue policy, the approved yield also affects the revenue guarantee. Using a $4.50 projected price:
- Farm A: 135 × $4.50 = $607.50 per acre
- Farm B: 105 × $4.50 = $472.50 per acre
This does not mean a higher APH automatically makes a policy more profitable. Greater coverage can increase the amount of insurance, but premiums and premium rates may also change.
The purpose of APH is to create a supportable estimate of the farm’s expected production—not to select the highest possible number.
5. What Production Records Are Required?
A production report must contain acceptable yield information and be supported by verifiable records.
Depending on the crop and marketing method, useful records may include:
- Grain elevator settlement sheets
- Scale tickets
- Warehouse receipts
- Processor records
- Gin records
- Sales receipts
- Measurement records for stored production
- Feed records
- Harvest records
- Commercial storage statements
- Appraisal records
- Claim documents
- Maps identifying production by unit
- Acreage records
- Production worksheets
The records should show enough information to connect the reported production to the correct crop, crop year, acreage and insurance unit.
Commingled Production
Problems can occur when grain from multiple units is mixed before separate production is measured.
If a producer wants optional units or other separated databases, production records normally must preserve that separation. A single total from several fields may not support the individual yields reported for each unit.
Before harvest, ask the crop insurance agent how production should be measured and documented.
Farm-Stored Production
Grain stored on the farm may require bin measurements, load records or other acceptable documentation. Existing grain should be measured before new production is added to the same structure.
A practical process includes:
- Identify the bin or storage structure.
- Measure any existing inventory.
- Record the crop and crop year.
- Track loads placed into storage.
- Keep production separated when the policy requires separate records.
- Retain measurement and disposition records.
Quality-Adjusted Production
Production affected by low test weight, toxins, foreign material or other qualifying quality problems may be adjusted under applicable policy provisions.
The production used to settle a claim may also affect the yield recorded for that crop year. Producers should review claim documents carefully and confirm how production to count will be entered in the APH database.
6. What Happens With Fewer Than Four Years of Records?
A new farmer, a producer planting a new crop or a farmer adding land may not have four years of acceptable actual production
