Pay back period can be estimated to determine the feasibility of making a capital investment that Will provide energy saving, simple payback period s an indication of the amount of time it will take for an organization to recover the cost of an energy saving investment which is purchased. The formula for estimating simple pay back period is:

Payback Period = Cost of improvement (Rs)

                             Average Yearly Saving (Rs)

For example , if adding insulation to ceiling at a cost of Rs 2000/- is expected to provide a Rs. 1000/- saving each year, the simple payback pay for itself in a 2 year period.
