Greenhouse and irrigation cost calculator
Plan the capital scope for a retrofit, expansion or new commercial project using your own prices. Editable assumptions, immediate totals — not supplier quotations.
Project inputs
Changing currency relabels numbers; it does not convert them. Re-enter prices in the selected currency. Default allowances are editable planning assumptions, not fees.

Enter all non-negative values and at least one positive area. Enter zero for an unused scope.
Confirm tax, shipping, site works, water supply, pumps, treatment, climate equipment, power and permits. Include them only when covered by your prices or allowances. Do not count irrigation twice if it is already in the greenhouse price.
Commercial projects from USD 250K are reviewed by a supplier-neutral sourcing specialist. Submitting a request is free for buyers; the selected currency does not establish eligibility.
Method and scope
Area × unit cost for each system, then ancillary costs, then reserve. Irrigation may serve the greenhouse or separate open-field land: specify which in your request. All input prices must use one currency and a consistent tax basis. Operating costs, lost production, financing, revenue and ROI are not calculated.
Frequently asked questions
Does this calculator use live supplier prices?
No. Results update as you edit your own unit prices from recent quotes or a professional budget. There is no supplier-price feed or currency conversion.
How is the investment calculated?
Greenhouse area in m² × cost per m², plus irrigated area in hectares × cost per hectare. Ancillary costs are added to that subtotal; reserve is then calculated on the subtotal including ancillary costs.
Can I compare retrofit and expansion options?
Yes. Enter only the area and systems in each option, record each result and compare the same tax and equipment scope. Include shared-system upgrades and production disruption separately. This tool calculates capital costs, not savings, revenue or ROI.
