Project Inputs
Enter your project parameters. 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.

Lifecycle Cost Optimised System
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-optimized scenario over the project's design life.
Return on Investment
Cumulative net present value over 20 years, with power costs escalated and all future cashflows discounted to present value. The optimised system is sized for lowest lifecycle cost (the non-optimized scenario carries 50% higher power and maintenance cost, 20% lower capital cost, and 5% lower yield).
Assumptions & Notes
- As operational lifetime increases, Operating Cost (OPEX) forms an increasing proportion of the total lifecycle cost.
- Capital cost is derived from an indicative rate per hectare for the selected system type, based on typical Southern African conditions, and is for high-level planning only (not a formal design or quotation).
- Power consumption is calculated from the irrigation demand, system efficiency, pump head and application rate, using typical pump, VSD and motor efficiencies.
- A management factor specific to each system type is applied to the target yield to reflect achievable performance.
- Total CAPEX carried into the ROI calculation is System CAPEX plus the approximate design cost (5% of System CAPEX).
- The non-optimized scenario assumes 50% higher power and maintenance cost, 20% lower capital cost, and 5% lower yield than a lifecycle-optimised system.
- Repayments are calculated on the loan interest rate and term entered, and cease once the loan is repaid.
