Greenhouse Calculator

A naturally ventilated polyhouse (NVPH) costs around ₹1,360 per sq. metre (about ₹65 lakh per acre turnkey), a fan & pad climate-controlled greenhouse with NFT hydroponics around ₹4,600 per sq. metre, and a net house around ₹600 per sq. metre. All figures are approximate — use the calculator above for an estimate based on your exact area.

Two schemes apply. For a 1-acre NVPH, the National Horticulture Mission (NHM) gives roughly ₹22 lakh and the National Horticulture Board (NHB) roughly ₹28 lakh (NHB is capped at ₹1 crore per project). The exact amount and caps vary by state and scheme year.

Yes. The Agriculture Infrastructure Fund (AIF) offers loans up to ₹2 crore with a 3% interest subvention and tenures up to 7 years, making the effective interest rate significantly lower than standard farm loans.

It depends on the crop. As an indicative example, a 1-acre polyhouse growing cucumber or coloured capsicum can earn roughly ₹15–18 lakh net profit per year, giving a payback of about 1.5–2 years on the post-subsidy investment. Polyhouse farm income is also 100% tax-free under Section 10(1). The calculator above estimates revenue, net profit, ROI % and payback for your chosen crop.

High-value, long-duration crops give the best returns. Coloured (red and yellow) capsicum and seedless cucumber are the most popular and profitable choices in a naturally ventilated polyhouse, followed by exotic vegetables, tomato and flowers such as gerbera and rose. A 1-acre polyhouse growing coloured capsicum or cucumber can earn roughly ₹15–18 lakh net profit per year. Select your crop in the calculator above to see its estimated revenue, profit and ROI.

You can start small — from just a few hundred square metres — but 1 acre (about 4,000 sq. m) is the most common and bankable size, because it makes the best use of government subsidy and gives strong economies of scale. Many farmers begin with a quarter- to half-acre and expand as cash flow grows. Enter any land size in the calculator to see the cost, subsidy and returns for your plot.

It depends on your crop, climate and budget. A naturally ventilated polyhouse (NVPH, around ₹1,360 per sq. m) is the most popular all-round choice for capsicum, cucumber and exotic vegetables. A Fan & Pad greenhouse with NFT hydroponics (around ₹4,600 per sq. m) is fully climate-controlled for the highest yields — ideal for premium leafy crops like lettuce. A Net House (around ₹600 per sq. m) is the lowest-cost option with the quickest payback, ideal for capsicum and tomato. Compare all three side by side in the calculator above.

Under the National Horticulture Board (NHB) scheme you register your project on the NHB portal, get a term loan sanctioned from your bank, and submit a Detailed Project Report (DPR). The credit-linked subsidy — up to ₹1 crore per project — is released after the polyhouse is built and inspected. Agrifirst prepares your DPR and guides you through the entire application, loan and inspection process end to end.

A well-built polyhouse structure lasts around 15–20 years. The UV-stabilised polyethylene film is usually replaced every 3–4 years and the insect net periodically, while the galvanised-steel frame is built for the long term. Routine upkeep — cleaning, drip-system checks and timely film and net replacement — keeps the structure productive for its full life. Agrifirst provides agronomy support and after-sales service throughout.

It gives a reliable indicative estimate using current NHB subsidy and AIF loan norms. All figures are approximate — final cost, subsidy eligibility, loan terms and crop returns depend on your state, vendor quotation, bank approval and market prices, so talk to Agrifirst for a precise quote.
