Calculation method
Calculation method
Gross margin by crop ($)
Area × (yield per hectare × sale price − variable cost per hectare).
Gross margin by hectare ($/ha)
Yield × price − variable cost per hectare.
Total crop revenue ($)
Sum area × yield × sale price.
Total variable cost ($)
Sum area × direct variable cost per hectare.
Combined gross margin ($)
Total crop revenue − total variable cost.
