| Leased cultivated land |
Fixed |
Use $22,500 per month in the first year: 450 leased acres at $50 per acre per month. |
Treating land lease as crop-linked, even though rent is due before harvest. |
| Seeds, fertilizers, crop protection |
Variable |
Model as 9.0% of revenue in the first year, falling to 8.0% by Year 5. |
Putting input purchases into fixed overhead and hiding margin swings. |
| Fuel, equipment maintenance and repairs |
Semi-variable |
Use 4.0% of revenue in the first year, with a usage-linked pattern as acreage and field activity rise. |
Assuming fuel and repairs are fully fixed because equipment is already owned. |
| Logistics and transportation |
Variable |
Model as 3.5% of revenue in the first year because shipping rises with harvested and sold volume. |
Leaving freight in overhead instead of tying it to sales volume. |
| Quality testing and certification fees |
Variable |
Use 1.5% of revenue in the first year, especially for food-grade and certified sustainable lots. |
Ignoring testing fees until premium crops scale, which overstates contribution margin. |

Fixed |
Include $10,000 per month from Month 1 through the planning period. |
Treating storage as variable when the lease runs whether bins are full or empty. |
| Utilities for office and basic storage |
Semi-variable |
Start with the $1,200 monthly base amount, then review usage if storage or processing load changes. |
Modeling utilities as fully fixed and missing higher operating load in harvest months. |
| Equipment operators |
Semi-fixed |
Step payroll up as acreage grows: 2.0 FTE in Year 1, 3.0 in Year 2, and 5.0 by Year 5. |
Spreading operator payroll as a percent of revenue instead of adding labor in staffing steps. |
