Gross Margin Calculator & Compare Your Crops
Ranks crops
“The best tip on this tool is probably in the comments already.
Compare crops the way farm planners do — from yield, price and variable costs get the gross margin per acre/hectare and in total, the GM %, and the break-even yield and price.
Enter your crop budget
Next: compare crops side by side on gross margin per acre — the highest GM/area is usually the better use of that land. To lift a thin margin, cut variable costs (cheaper inputs, better timing) or raise yield/price; aim to clear the break-even of 23 yield or ₹1,125 price.
GM excludes fixed costs (land, machinery, family labour); use it to rank enterprises, not to judge whole-farm profit.

The metric farm planners actually use
When you're deciding what to grow on limited land, comparing full net profits is messy — fixed costs like rent and machinery are much the same whatever you plant. Gross margin strips those out and shows the return that actually varies with the crop: gross income minus variable costs, per acre or hectare. It's the standard yardstick in farm business planning for exactly this reason.
This tool computes the gross margin per area and in total, the GM percentage, and the break-even yield and price, so you can rank crops, stress-test prices, and build a whole-farm plan (sum the gross margins, subtract fixed costs, and you have your profit). Include all variable costs, be consistent across the crops you compare, and use the break-even figures to judge risk. Pair it with the Crop Profit, Break-Even Yield and Cost of Cultivation tools.

Frequently Asked Questions
What is gross margin?+
Gross margin is gross income minus variable (direct) costs, usually expressed per acre or hectare: GM = (yield × price) − variable costs. It's the standard farm-planning metric for comparing crop enterprises, because it isolates the return that varies with the crop before fixed costs muddy the picture.
How is gross margin different from net profit?+
Gross margin subtracts only variable costs (seed, fertiliser, sprays, casual labour, fuel); net profit also subtracts fixed/overhead costs (land rent, machinery depreciation, permanent labour, interest). GM is best for comparing enterprises; net profit tells you whether the whole farm pays. Use both.
What counts as a variable cost?+
Costs that change with the crop and area: seed, fertiliser, pesticides, irrigation water/fuel, contract operations, casual harvest labour and crop-specific inputs. Costs that you'd pay regardless of which crop you grow (rent, owned machinery, salaried staff) are fixed and are excluded from gross margin.
Why compare crops on gross margin?+
Because fixed costs are largely the same whichever crop you choose, the enterprise with the higher gross margin per area usually contributes more to covering those fixed costs and to profit. Ranking crops by GM/area is the quickest, fairest way to decide what to grow on limited land.
What is a good gross-margin percentage?+
It varies by crop and system, but as a rough guide a GM below ~30% of income is thin, 30–55% is healthy, and above ~55% is strong. A negative gross margin means the crop doesn't even cover its variable costs — a clear signal not to grow it as planned.
What is break-even yield and price here?+
Break-even yield = variable cost ÷ price (the yield needed to cover variable costs), and break-even price = variable cost ÷ yield (the price needed at your expected yield). Below either you have a negative gross margin. The tool shows both so you can judge the risk.
How do I improve gross margin?+
Raise yield (better agronomy, varieties, irrigation), get a better price (quality, timing, direct sale), or cut variable costs (efficient inputs, less waste, shared operations) — without raising them so much that yield falls. The tool shows the GM response instantly as you change each figure.
Should I use gross margin for whole-farm planning?+
Yes — sum each enterprise's gross margin (GM/area × area) across the farm, then subtract total fixed costs to get the farm profit. This 'gross margin budgeting' is the backbone of farm business planning and lets you test crop-mix changes before committing.
Does gross margin include my own labour?+
Family/owner labour is often treated as fixed and excluded from gross margin, but if you hire casual labour for that crop it's a variable cost and should be included. Be consistent across enterprises you're comparing, and if labour is scarce consider also calculating GM per labour-hour.
Can I use this for livestock or per-unit enterprises?+
Yes — enter output per unit (e.g. per cow or per 100 birds) as the 'yield', the price, and the variable cost per the same unit, with the number of units as the area. The gross margin per unit and total still apply. It's a general enterprise-margin tool.
