Plan winter hay
Calculate whole bales, total weight, cost, storage loss, and feeding waste for a mixed herd or one species.
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.
Work through hay, price, storage, water, and manure in one temporary five-step workspace. Nothing is saved.

What do you need to work out?
Compare bale costs
Compare offers by bale, pound, and ton, or compare round and square bales after waste.
Check storage space
Turn a bale count into storage volume and floor area, or check a measured rectangular bay.
Plan winter logistics
Estimate daily water, backup storage, manure, bedding, and hauling loads.

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.
Every result is a planning estimate. Confirm animal needs, actual bale weights, barn constraints, and local prices before acting.
