Investment analysis calculator
This calculator indicates the payback period when investing in an LED installation compared to a lighting installation using conventional light sources. Please insert your input below. The payback time is calculated by dividing the difference in operating costs over the difference in investments. From this calculation it could be understood as to how many years you would need to “earn back” your initial investment. The method returns a simplified result, i.e. all parameters like cleaning cost, discount rate etc. are not included.
Please put in information in all cells for the calculator to work correctly.
