This calculator indicates the payback period when investing in an LED luminaire compared to a lighting installation using conventional lightsources.
Please insert your figures below. The payback time is calculated by dividing the difference in operating costs by the difference in investments. From this calculation you can determine how many years it would take to "earn back" your initial investment. The method returns a simplified result, i.e. all parameters like cleaning costs, discount rate, etc. are not included.
Please input information in all cells for the calculator to work correctly.
