Your estimate

Estimated refrigerator running cost

₹302

At the entered 35% duty cycle, the refrigerator may use about 37.8 kWh over 30 days.

Energy for period37.8 kWh
Equivalent run time/day8.4 hours
Annualised cost₹3,679

Keep in mind

Duty cycle is a user-entered estimate of compressor running time, not a built-in appliance claim.

Ambient temperature, door opening, defrost heaters, load and appliance condition can materially change consumption.

How this estimate works

A simple formula, visible assumptions

Energy (kWh) = rated watts × 24 hours × duty-cycle percentage × days ÷ 1,000; cost = energy × tariff.

The result updates in your browser as you change an input. It is a planning estimate, so compare it with real bills, product specifications and a qualified professional's assessment.
