Estimating expected revenue before harvest helps with everything from arranging storage and transport to negotiating advance sale contracts. This calculator converts your field area into an expected yield and revenue figure, letting you adjust for field-specific conditions like pest pressure, soil quality, or a difficult season that would push actual output below the crop's typical average.
Expected Yield = Field Area × Average Yield per Unit Area for the Crop × (1 + Condition Adjustment %). Expected Revenue = Expected Yield × Market Price. The condition adjustment lets you scale the baseline average up or down based on your own field's performance history.
| Crop | Average Yield |
|---|---|
| Wheat | 1,100-1,300 kg/acre |
| Rice (paddy) | 1,000-1,400 kg/acre |
| Maize | 1,600-2,200 kg/acre |
| Cotton (seed cotton) | 500-700 kg/acre |
| Sugarcane | 25,000-30,000 kg/acre |
For 8 acres of wheat with an average yield of 1,200 kg/acre, but a -10% adjustment for late sowing this season: Expected yield = 8 × 1,200 × 0.9 = 8,640 kg. At a market price of PKR 4,200/40kg (PKR 105/kg), expected revenue = PKR 907,200. Comparing this to your Crop Cost of Production figure tells you your margin before harvest even begins.
A well-informed estimate using your field's historical performance and this season's known conditions is typically within 10-15% of actual harvest, though extreme weather events late in the season can move actual results further from any early estimate.
Common negative adjustments include late sowing, disease or pest outbreaks, water stress during critical growth stages, and poor stand establishment. Positive adjustments apply when a field has a strong fertility history or received timely, adequate irrigation throughout the season.
Your own field's 3-year average is generally more reliable than a regional average, since soil quality and management practices vary significantly between farms even within the same district.
Many farmers pre-sell part of their crop to lock in a price before harvest. Having a realistic yield and revenue estimate helps you decide how much of the crop to commit to a forward contract versus holding for the open market.
