Why Calculation Details matter
RanchAssist is designed so users can audit the assumptions behind a planning result. Before using the output for purchasing, scheduling, budgeting, or field decisions, review the source inputs and any user-editable assumptions.
Core calculation relationships
- Total forage is based on usable acres × user-entered forage production.
- Usable forage is reduced by the planning assumptions for utilization/harvest/reserve/buffer as configured in the tool.
- Daily animal demand is based on live weight × daily dry-matter intake percentage.
- Herd demand scales animal demand by head count.
- The selected question mode rearranges the same supply-and-demand relationship to solve for head count, days, or acres.
Results to review together
- Planning head count
- Grazing days
- Acres per head
- Total and usable forage
- Daily animal and herd demand
- Forage reserve
- Animal units and aum equivalents
How to sanity-check the result
Change one important assumption at a time and confirm the result moves in the direction you expect. If a small change creates a very large result change, check units, percentages, duplicated rows/features, and any hidden Advanced settings.
Rounding and purchase quantities
Where the tool converts a calculated need into purchasable whole units—such as bales, rolls, packages, loads, or other discrete quantities—the purchase quantity may round upward even when the mathematical requirement is fractional. Review Calculation Details for the current tool behavior.
Planning limitation
Local forage conditions and professional or local guidance should govern real stocking decisions. Calculator outputs are planning estimates, not carrying-capacity guarantees.
