Crop Yield per Acre Calculator
Calculate harvested grain yield per acre in bushels, metric kg/ha equivalents, total tonnage, and gross revenue per acre.
Calculate Crop Yield per Acre
Enter total harvested grain bushels, field acreage, and crop type to compute yield per acre.
Calculation Results
Calculated using standard agricultural extension yield formulas: \text{Yield per Acre (bu/acre)} = \frac{\text{Total Bushels}}{\text{Harvested Acres}}
Quick Summary
The Crop Yield per Acre Calculator evaluates field production density ($\text{Yield}_{\text{bu/acre}} = \frac{\text{Total Bushels}}{\text{Acres}}$) in bushels per acre, metric kilograms per hectare (kg/ha), total scale tonnage, and revenue per acre.
Formula Explanation
\text{Yield per Acre (bu/acre)} = \frac{\text{Total Harvested Grain (bushels)}}{\text{Harvested Acres}}
\text{Yield per Hectare (kg/ha)} = \frac{\text{Yield (bu/acre)} \times \text{Lbs per Bushel} \times 0.453592}{0.404686}
\text{Revenue per Acre} = \text{Yield (bu/acre)} \times \text{Selling Price per Bushel}How It Works
The Crop Yield per Acre Calculator divides total harvested scale bushels by field acreage to derive per-acre productivity. It converts US bushels per acre into metric kilograms per hectare (kg/ha) using official grain test weights (56 lbs/bu for corn, 60 lbs/bu for soybeans and wheat).
Step-by-Step Worked Example
Practical Problem: A grower harvests 20,000 bushels of corn from 100 acres at a market price of $4.80/bushel. Calculate yield per acre in bushels and kg/ha.
- Step 1: Yield per acre: $20,000 / 100 = \mathbf{200.0\text{ bu/acre}}$.
- Step 2: Total harvested weight: $20,000 \times 56\text{ lbs} = \mathbf{1,120,000\text{ lbs}}$ ($560\text{ short tons}$).
- Step 3: Metric conversion (kg/ha): $(200 \times 56 \times 0.453592) / 0.404686 = \mathbf{12,554\text{ kg/ha}}$ ($12.55\text{ t/ha}$).
- Step 4: Revenue per acre: $200 \times \$4.80 = \mathbf{\$960.00\text{ per acre}}$.
- Step 5: Total gross revenue: $20,000 \times \$4.80 = \mathbf{\$96,000\text{ gross revenue}}$.
Real-World Calculation Examples
Scenario 1: High-Yield Irrigated Corn
Parameters: 24,000 bu, 100 acres, $4.80/bu
Result: 240.0 bu/acre (15,065 kg/ha, $1,152/acre rev). High-yield corn benchmark.
Scenario 2: Midwest Soybean Harvest
Parameters: 6,500 bu, 100 acres, $12.50/bu
Result: 65.0 bu/acre (4,371 kg/ha, $812.50/acre rev). Top soybean yield.
Scenario 3: Winter Wheat Field
Parameters: 5,500 bu, 80 acres, $5.80/bu
Result: 68.8 bu/acre (4,623 kg/ha, $398.75/acre rev). Winter wheat performance.
Scenario 4: Dryland Drought Corn
Parameters: 13,000 bu, 100 acres, $4.50/bu
Result: 130.0 bu/acre (8,160 kg/ha, $585/acre rev). Drought stress yield.

Frequently Asked Questions (FAQ)
How is crop yield per acre calculated?
Divide total clean grain bushels harvested from a field by total harvested field acreage ($\text{Yield} = \text{Total Bushels} / \text{Acres}$).
How do I convert bushels per acre to kilograms per hectare (kg/ha)?
For corn (56 lbs/bu): Multiply bu/acre by 62.77. For soybeans or wheat (60 lbs/bu): Multiply bu/acre by 67.25.
What is average US corn yield per acre?
US national average corn yield ranges between 170 and 180 bushels per acre, with top irrigated acres exceeding 250 bu/acre.
What is average US soybean yield per acre?
US national average soybean yield ranges between 50 and 55 bushels per acre, with high-yield Midwest fields reaching 70–85 bu/acre.
What is the difference between wet yield and dry yield per acre?
Wet yield uses unadjusted scale harvest weight. Dry yield adjusts for moisture shrink down to commercial standard (15% for corn, 13% for soybeans).
How many acres are in a hectare?
1 hectare equals 2.47105 acres ($1\text{ ha} = 2.471\text{ acres}$; $1\text{ acre} = 0.404686\text{ ha}$).
How does combine yield monitor mapping work?
Yield monitors use impact sensors and GPS to log instantaneous yield per acre across a field grid, generating precision yield maps.
Why does crop yield per acre vary across a single field?
Field yield variability stems from soil type differences, organic matter, topography, drainage, soil compaction, and nutrient availability.
What is 100-bushel corn in metric terms?
100 bu/acre corn equals approximately 6,277 kg/ha or 6.28 metric tons per hectare (t/ha).
How can farmers increase crop yield per acre?
Yield increases through variable-rate seeding and fertilization, split nitrogen applications, fungicide disease protection, and soil compaction reduction.
