Grazing Plan Calculator

Plan Your Rotation

Size your herd against your acres and see what rotation your land can sustain.

What managed grazing comes down to

Managed grazing is one question: how many animals can you run on how many acres for how long without damaging next year’s stand? Overgrazing costs you in forage the following year — thinner stand, weedier ground, slower recovery after drought.

This calculator lets you enter your acres, herd, and paddock count, pick a rotation pattern, and see what rest periods your land would need. Print the results for your NRCS planner — the math here is what they’ll want to see.

1. Your Pasture

DM = dry matter (accounts for water content in fresh forage)

2. Your Herd

This calculator works for cattle, sheep, goats, horses, and bison. Add your operation type to start.

months
How many months do your pastures actively grow?

3. Rotation Setup

More paddocks = longer rest periods = better forage recovery. Most rotational systems use 4-12 paddocks.

This calculator provides planning estimates based on regional averages. Actual forage productivity depends on soil type, precipitation, grazing history, and management. Farmer's Navigator is not affiliated with USDA or NRCS.
