How the Grain Moisture Yield Adjustment Calculator works
Yield at standard moisture = measured yield × (100 − harvest moisture) ÷ (100 − standard moisture). Wet grain weighs more because of water, so the measured bushels are cut back to the moisture used for sale, which is 15.5% for corn, 13% for soybeans, and 13.5% for wheat in much of the United States. Drying cost per acre = points of moisture above standard × cost per point per bushel × yield. This is a pure water shrink and does not include the handling shrink some buyers add on top. Check your elevator for its own table. Example: with Measured yield 210 bu/ac, Moisture at harvest 19.5 %, Standard moisture 15.5 %, Drying cost per point per bushel 0.04 $, and Field size 100 acres, the result is Yield at standard moisture (bu/ac) = 200.1; Water shrink (bu/ac) = 9.9; Shrink share of the measured yield = 4.73%.
Inputs and results
The Grain Moisture Yield Adjustment Calculator takes 5 inputs and gives 6 results.
What you enter
- Measured yield (bu/ac) — starts at 210.
- Moisture at harvest (%) — starts at 19.5.
- Standard moisture (%) — starts at 15.5.
- Drying cost per point per bushel ($) — starts at 0.04.
- Field size (acres) — starts at 100.
What you get
- Yield at standard moisture (bu/ac)
- Water shrink (bu/ac)
- Shrink share of the measured yield
- Drying cost per acre
- Drying cost for the whole field
- Total bushels at standard moisture
Example: Grain Moisture Yield Adjustment Calculator with the starting values
With measured yield 210 bu/ac, moisture at harvest 19.5 %, standard moisture 15.5 %, drying cost per point per bushel 0.04 $ and field size 100 acres, the calculator returns:
| Yield at standard moisture (bu/ac) | 200.1 |
|---|---|
| Water shrink (bu/ac) | 9.9 |
| Shrink share of the measured yield | 4.73% |
| Drying cost per acre | $33.6 |
| Drying cost for the whole field | $3,360 |
| Total bushels at standard moisture | 20,006 |

Grain Moisture Yield Adjustment Calculator FAQ
How do I use the Grain Moisture Yield Adjustment Calculator?
Enter measured yield, moisture at harvest, standard moisture and drying cost per point per bushel in the fields, then read yield at standard moisture (bu/ac), water shrink (bu/ac), shrink share of the measured yield and drying cost per acre in the result panel.

What does the Grain Moisture Yield Adjustment Calculator calculate?
Adjust harvest yield to standard moisture and price the drying. It returns yield at standard moisture (bu/ac), water shrink (bu/ac), shrink share of the measured yield and drying cost per acre from the 5 values you provide.
What values does the Grain Moisture Yield Adjustment Calculator start with?
It opens with measured yield 210 bu/ac, moisture at harvest 19.5 %, standard moisture 15.5 % and drying cost per point per bushel 0.04 $ so you can see a working result straight away. Replace them with your own numbers, or press Reset to return to these starting values.
