farming Calculators
Last updated: May 2026
Crop Yield Estimator
Estimate total crop tonnage by multiplying field area in hectares by expected yield per hectare.
Fertilizer Application Rate Calculator
Calculate the total fertilizer required for a field by multiplying field size in hectares by the recommended application rate in kilograms per hectare.
Irrigation Water Requirement Calculator
Calculate the total daily irrigation water requirement in cubic meters by multiplying crop area and water need per day, then dividing by system efficiency.
Seed Planting Rate Calculator
Calculate the total seed quantity needed for a field including a buffer for germination losses, wastage, and seeder calibration.
Livestock Feed Calculator
Calculate total feed required for a herd over a chosen feeding period from animal count, daily intake per animal, and feeding days.
Greenhouse Heating Cost Calculator
Estimates the daily electricity cost to heat a greenhouse based on its size, heating intensity, and your local energy rate.
Pesticide Spray Volume Calculator
Calculates the volume of concentrated pesticide needed for a given field area based on spray volume and concentration.
Farm Profit Margin Calculator
Computes the percentage of revenue that remains as profit after all farm costs are deducted.
Lime Requirement Calculator
Estimates the tonnes of agricultural lime needed to raise soil pH to a target level across a given field area.
Crop Spacing Calculator
Calculates the total number of plants that fit in a rectangular field given plant-to-plant and row-to-row spacing.
Crop Yield Calculator
Estimate the total tons of harvested crop per acre by entering your plant population, harvest success rate, and average plant weight.
Farm Profitability Calculator
Determine your net profit per acre by subtracting variable, fixed, and labor costs from total farm revenue.
Seed Spacing Calculator
Calculate exactly how many seeds you need to plant a field by specifying field dimensions, row spacing, plant spacing, and seeds per hole.
Pesticide Mixing Calculator
Determine how much pesticide concentrate to add to your spray tank for a given field area, application rate, and tank size.
Soil pH Adjustment Calculator
Estimate how many tons of agricultural lime (to raise pH) or elemental sulfur (to lower pH) your field needs, based on current and target pH values, field size, soil type, and organic matter content.
Harvest Timing Calculator
Estimate the optimal harvest date for your crop by combining planting date, growing degree day accumulation, and field drying rate.
Irrigation Scheduling Calculator
Determine how many inches of water your crop needs right now based on evapotranspiration, recent rainfall, days since last irrigation, and soil type.
Livestock Feed Cost Calculator
Calculate annual feed costs per herd based on animal type, average weight, production stage, and current feed prices.
Farm Loan Payment Calculator
Calculate monthly, seasonal, or annual loan payments for farm land, equipment, or operating credit.
Crop Insurance Premium Calculator
Estimate your annual crop insurance premium based on insured acres, APH yield, price election, coverage level, and county risk.
Field Capacity Calculator
Estimates how many days your farm machinery needs to complete a field operation.
Pasture Stocking Rate Calculator
Calculates how many animal units a pasture can sustainably support across a grazing season.
Grain Storage Ventilation Calculator
Estimates the airflow needed to dry or safely store grain in a bin based on grain type, bin geometry, and moisture targets.
Farm Break-Even Analysis Calculator
Calculates the minimum price per bushel a farmer must receive to cover all production costs.
Fertilizer Cost Calculator
Estimates total fertilizer expenditure for a field based on N-P-K application rates, field size, and product type.
Irrigation Water Calculator
Estimate seasonal irrigation water needs and total water costs for any crop and field size.
Greenhouse Climate Calculator
Estimate monthly heating and cooling energy costs for a greenhouse based on its size, climate zone, insulation, and target temperature.
Soil Amendment Calculator
Calculate how much agricultural lime and organic matter you need — and what it will cost — to bring your soil to its target pH and fertility level.
Farm Equipment Depreciation Calculator
Calculate the annual tax-deductible depreciation on farm equipment using purchase price, salvage value, usage intensity, and your tax rate.
Pasture Rotation Calculator
Calculate the sustainable carrying capacity of your rotational grazing system based on paddock count, grass growth, and livestock units.
Crop Yield Estimator
Estimate total harvest weight from any field by entering its size, planting density, per-plant yield, mortality rate, and a weather adjustment factor.
Farm Equipment Depreciation Calculator
Find the current book value of any piece of farm equipment after years of use, using straight-line depreciation down to its salvage value.
Grain Storage Cost Calculator
Determine whether storing grain after harvest is financially worthwhile by comparing the net gain from a higher future price against storage, drying, and interest carrying costs.
Farm Break-Even Analysis Calculator
Calculate the minimum crop price per bushel needed to cover all fixed and variable production costs on your farm.
Crop Yield Profit Calculator
Calculate net farm profit by subtracting per-acre seed, fertilizer, labor, and equipment costs from total crop revenue.
