About Polyhouse Cost Calculator

Polyhouse capital cost is area x rate per square metre, which varies with structure type — bamboo and wooden houses are cheapest, galvanised iron naturally ventilated houses mid-range and fan-and-pad climate-controlled houses several times more. Netting off subsidy and spreading the balance over the structure life gives the annual capital charge the crop must cover.

Formula

Polyhouse cost

Gross = area x cost per m2; net = gross x (1 - subsidy %); annualised = net / life in years

Worked example

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Subsidy rates, ceilings and eligibility vary by scheme, state and category of beneficiary. Confirm current terms with the horticulture department before committing.

Frequently Asked Questions

What does the cost per square metre cover?

Structure, cladding film, doors and basic ventilation. Irrigation, fertigation, shade nets, insect screens and a water source are usually extra and can add 20-40%.

How often must the film be replaced?

UV-stabilised polythene lasts 3-5 years depending on grade and sunlight. Budget a recurring cost for recladding separately from the structure life.
