Our investment analysis calculator calculates the repayment time when
investing in an LED installation versus an installation with
conventional light sources.
The repayment time is calculated by dividing the difference in the operational costs by the difference in investments. This can be understood as the number of years you need to “earn back” your initial investment. The calculator also provides energy savings figures (in percentage) by choosing the LED alternative.
All of the fields in the calculator must be completed as precisely as possible. This applies to, among other things, the number of luminaires and the price per luminaire that will be installed, as well as the installation costs and energy use for new and existing light luminaires. Also the annual operating time for the installation and light source lifetimes are important.
