Pay Back Calculator

This calculator gives payback period when you upgrade your lighting to LED lights i.e. the amount of time in which the investment on LED lights is recovered by the savings made in electricity costs.
Please note that this calculation does not factor in various other savings in the form of replacement costs of other lights, low maintenance costs and life of the LED lights.
