Irrigation System ROI Calculator
Calculate the return on investment associated with a new or upgraded irrigation system.
Capital cost is derived from a rate per hectare for the selected system type, and a management factor adjusts the achievable yield. Power and maintenance costs are expressed as net present values over the analysis period. Defaults reflect typical Southern African conditions.
Headline economics of a professionally engineered system, sized for lowest lifecycle cost.
Power consumed assumes typical efficiencies of 75% (Pump), 95% (Variable Speed Drive) and 75% (Motor). Repairs & maintenance is estimated at 2% of capital cost per year. Design cost is an approximate allowance only (actual professional fees are confirmed in a formal proposal) and is included in the total CAPEX carried into the ROI calculation.
See the year-by-year return, 5/10/20-year ROI, and how a lifecycle-cost optimised system compares to a non-optimised scenario over the project's design life.

Optimised system versus a non-optimised scenario (20% less capital, 50% higher power & maintenance cost, 5% less yield uplift), discounted over the project's design life.

This tool models a well-designed system in isolation. Whether your project gets there depends on the engineering behind it.
