Why actual use varies
Power draw changes with appliance model, age, condition, voltage, settings, load, standby behaviour, ambient temperature, thermostat cycling, and household habits. A label value or typical preset may not match a particular appliance.
Why actual bills vary
Tariffs, slabs, time-of-use periods, taxes, fuel adjustments, duties, fixed charges, subsidies, minimum bills, and billing periods can change. A calculator result may exclude some of these items unless they have been entered explicitly.
Important decisions
Verify material purchasing, budgeting, electrical, or safety decisions with the appliance documentation, a current utility tariff, a suitable meter, and a qualified professional where appropriate.
