Frequently asked questions
How much does it cost to build a polyhouse in India?
A naturally ventilated polyhouse (NVPH) costs around ₹1,250 per sq. metre (about ₹50 lakh per acre), a fan & pad climate-controlled structure around ₹2,200 per sq. metre, and a net house around ₹635 per sq. metre. All figures are approximate — use the calculator above for an estimate based on your exact area.
What government subsidy is available for polyhouses?
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.
Can I get a loan for a polyhouse project?
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.
What ROI and profit can a polyhouse give?
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.
How accurate is this polyhouse calculator?
It gives a reliable indicative estimate using current NHM/NHB and AIF 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.
