Every tool on this site was designed for Columbia Basin and Pacific Northwest production agriculture — with real numbers, real formulas, and zero fluff.
Find the minimum price per bushel and yield per acre needed to cover every dollar of your production costs. Enter costs once — see break-even price, break-even yield, net return, profit margin, and a 5×5 price/yield sensitivity table.
Find the maximum rent you can afford per acre, or evaluate whether a specific rent pencils out. Outputs land value at 2.5–3.5% cap rates and a rent sensitivity table.
Calculate GPM requirements, application rates in acre-inches, and system sizing for center pivot irrigation. Built for Columbia Basin conditions.
Calculate total production, gross revenue, and yield per acre for up to five crops at once. Supports corn, soybeans, wheat, canola, dry beans, and potatoes with multiple price and yield units.
Two calculators in one: grain and row crop seeding rates (seeds/acre, lbs/acre) with germination and emergence adjustments; and potato seed calculations with chip loss, sacks to purchase, and seed cost breakdown.
Calculate moisture shrink when drying grain, bushels lost to moisture removal, and total drying cost. Shows net bushels after drying and cost per bushel of moisture removal.
Calculate product amounts per acre or per tank for pesticides and fertilizers. Single product mode and a tank mix / blend mode for multi-product applications, with total cost and cost per acre.
Reverse-engineer the nozzle output required to hit a target GPA at your field speed and boom spacing. Live TeeJet nozzle grid shows required PSI for 760 size/series combinations, color-coded by droplet size.
Assess blackspot and shatter bruise risk for potato harvest and handling operations. Rates risk based on pulp temperature, drop height, soil conditions, variety sensitivity, and handling speed.
Calculate grain bin capacity in bushels for round bins, flat storage, and bunkers. Enter diameter and grain depth for round bins; length and width for flat storage. Adjusts for corn, wheat, soybeans, canola, and other grains.
Calculate potato storage capacity in hundredweight for cellars, quonsets, and pile storage. Accounts for pile dimensions, packing density, and tare weight. Useful for contract reconciliation and inventory planning.
Calculate monthly and annual payments for agricultural loans — operating lines, equipment financing, and real estate. Includes an amortization schedule and total interest cost, plus a multi-loan debt overview for your full debt stack.
Enter your cost of production and expected yield or price to find the exact price or yield you need to break even. The 5×5 sensitivity table shows net return or loss at 25 price/yield combinations around your inputs.
Two modes: find the maximum rent you can afford (residual after all costs and your target operator return), or evaluate a specific rent offer against your crop budget. Outputs implied land value at 2.5%, 3.0%, and 3.5% cap rates.
Size your center pivot pump and calculate application rates. Enter field size and desired application depth to find required GPM, or enter pump GPM to find application rate in acre-inches per revolution.
Calculate field area in acres for circles, squares, partial circles (any degree), and custom polygons (3–8 sides). The pivot field mode breaks down irrigated circle area, dry corners, end-gun area inside and outside the field boundary, and outer buffer strips.
MyFarmCalc was built by people who understand Columbia Basin production agriculture — irrigated corn, potatoes, wheat, beans, and the economics that go with them. Every default value, hint, and benchmark reflects what farmers in Central Washington, Idaho, and the wider Pacific Northwest actually see in the field.
That said, the formulas work anywhere. Whether you're farming in Kansas, Alberta, or anywhere else, the math is the same — just swap in your local numbers.
