Irrigation Pumping Cost Calculator
Estimate the energy and rupee cost to pump a volume of irrigation water at a given head and tariff.
Energy (kWh) = volume(m³) × head(m) ÷ (367 × efficiency). Lower the head (avoid undersized pipe, keep the foot-valve clean) and run an efficient pump to cut the bill. Diesel pumping costs far more per m³ than grid electricity.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Irrigation Pumping Cost Calculator
Pumping is often the biggest running cost in irrigated farming, yet few growers know what a watering actually costs them. The energy needed to lift water rises with both the volume and the total head, divided by how efficiently the pump-and-motor set works. This tool turns your volume, head, efficiency and electricity tariff into the kilowatt-hours consumed and the rupee cost — including cost per cubic metre, so you can compare flood versus drip or grid versus diesel pumping.

Frequently asked questions
How much does it cost to pump irrigation water?+
Energy (kWh) = volume(m³) × head(m) ÷ (367 × efficiency); multiply by your tariff for the cost. For example, 1000 m³ at 30 m head and 55% efficiency uses about 1490 kWh — around ₹10,400 at ₹7/kWh. Reducing head and improving efficiency cut this directly.
How can I reduce my pumping cost?+
Lower the total head (use adequately-sized, clean pipe and minimise lift), maintain pump efficiency (correct impeller, no air leaks), switch thirsty flood irrigation to drip to pump less volume, and pump during cheaper tariff hours where available.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline and your data never leaves the device.
