MIDH's 2025 cost norms: production unit 30 lakh rupees, spawn unit 20 lakh, compost unit 30 lakh, each with 40 percent assistance for private growers and 50 percent in north-eastern and Himalayan states and scheduled areas. The low-cost unit is 2 lakh for a 200 square foot structure at 50 percent, up to five units per beneficiary. Assistance is credit-linked and back-ended: a bank loan is mandatory and the money arrives after the build. A cost norm is a ceiling for subsidy, not the price of a unit. Get local quotations.
