Farm profitability comes down to a simple identity — revenue minus cost — but the inputs that feed it swing widely by crop, region, and season. This calculator turns your yield, price, and five cost lines into per-acre profit, break-even points, and a price-sensitivity view so you can see where the money is made and how much risk you carry.
How the calculator works
Revenue is acres times yield per acre times price per unit. Costs are the sum of seed, fertilizer, pesticide, equipment/labor, and land rent — each entered per acre, then scaled by acreage. Net profit is revenue minus cost, and dividing by acres gives the per-acre figure that lets you compare fields of any size. Break-even price and break-even yield isolate the two variables you cannot fully control — what the market pays and what the field produces — and tell you how far each can fall before the crop stops covering its costs.
Inputs and what they mean
Yield and price together set revenue, so small changes in either move profit sharply. Grains are priced in bushels per acre; cotton, tomatoes, strawberries, potatoes, and alfalfa are priced per pound, which is why those crops show much larger yield numbers. On the cost side, fertilizer and land rent are usually the largest lines for row crops, while specialty crops like tomatoes carry far higher seed, labor, and equipment costs per acre but also much higher revenue. Enter realistic local numbers — university extension budgets are a good source — for the result to reflect your operation.
Limits and edge cases
This is a single-season, single-crop snapshot. It does not model crop insurance, government program payments, marketing-year average prices, basis, storage, multi-year rotations, or the risk of total crop failure. It assumes everything you plant is harvested and sold at one price. Use it for planning and comparison, not as a substitute for a full enterprise budget or advice from your lender or extension economist.
