Agriculture & Farming Calculators
7 free calculators · Updated for 2026/27
Farm margins depend on yield per hectare, input rates, labour costs and whatever environmental payments the holding can claim. Agriculture calculators work at that level, covering fertiliser application, expected harvests, stocking density, wages by grade and scheme payments, which makes them useful when planning a season, budgeting a field or preparing for a rent review.
Per-hectare costs and the break-even price per tonne come out of the Farm Operating Cost Calculator, while the Crop Yield Calculator estimates the harvest and what it is worth. The Livestock Stock Unit Calculator converts cattle, sheep, pigs and horses into stock units and the land they require, the BPS/ELM Payment Calculator adds up Sustainable Farming Incentive and ELM payments across environmental actions, and the Agricultural Worker Minimum Wage Calculator sets pay by AWO grade with overtime and holiday entitlement included.
