People feel satisfied if they have taken sufficient care of whatever will happen in future. What if you know about the approximate cost you will spend on electricity before buying any appliance? Will that change the buying decision? We are sure it will. How will that get impacted if we tell you that the operating cost (or cost of electricity used) of any electrical appliance is mostly more than the cost of buying any appliance, will that make you feel that you should buy an efficient appliance? If yes then do continue reading.

Sample operating costs of appliances

To prepare this article we did a small research on prices of various kinds of appliances and combined them with the knowledge that we have gained about electricity consumption of various appliances through sample home audits. And below are some results of the same:

Lifetime operating cost calculated above is derived using average unit cost of electricity across the country, which is Rs 6 per unit. Also the cost of appliance taken above is average cost of the appliance available in the market. Please note that the cost varies with time and it mostly increases. So the ratio will mostly be more than what is calculated above. Also you can check your own cost of electricity per unit using our calculator: Online Electricity Bill Calculator – For all states in India.

Usage is important factor to calculate Operating Cost

The values calculated above are based on standard usage values. If your usage is higher than that, then the operating cost will be more, if it is less, then it will be less. Higher the value of Operating Cost, more important it is to go for an efficient appliance so that the operating costs are less. So if you use an appliance more, it makes much more sense to buy an energy efficient version of the same.

Efficient appliances have lower operating costs

The values above are representative numbers and actual value of any appliance will depend on its efficiency and efficient use. Efficient versions of the appliances will always have lower operating costs as represented in case of tubelights and bulbs in the above table.

The point that we are trying to drive home with this article is that the operating costs of most appliances is more than the cost of buying, thus it is very important to keep that in mind while buying any appliance.
