Nine free farm-planning calculators

Calculate hay, bale costs, barn space, water, and manure.

Each free tool turns your herd, winter, bales, storage, and prices into a specific result: bales and tons, total cost and savings, square feet, gallons, or pounds of manure. No signup, no saved data, and every calculation runs in your browser.

Why these numbers hold up

BaleMath starts with published university extension rates, then makes the farm-specific choices visible: animal weight, season length, storage loss, feeding waste, bale weight, and price. Assumptions that still need stronger sourcing are labeled as estimates instead of dressed up as certainty.

Methods draw on named sources including University of Maryland Extension, Penn State Extension, Missouri Extension, West Virginia University Extension, and UMass Extension. Read the methodology and full source list before you buy, build, or change a ration.
