Refrigerator Electricity Cost Calculator
Calculate the running cost of a refrigerator — it runs 24 hours a day.
About the Refrigerator Electricity Cost Calculator
Whether you are comparing options or just need a quick check, the Refrigerator Electricity Cost Calculator delivers an accurate result instantly, with every input editable so you can model your own scenario.
Running an air conditioner, heater, refrigerator or other appliance has a monthly cost that is easy to underestimate. This Refrigerator Electricity Cost Calculator converts an appliance's wattage and your usage pattern into a real monthly and annual electricity cost, using your local per-unit tariff.
The calculation is straightforward: wattage times hours of use gives energy in kilowatt-hours, which multiplied by the per-unit rate gives cost. Because the tariff is an input, the result reflects your actual electricity price rather than a national average.
The biggest surprise for most households is the cost of cooling and heating. A 1.5-ton air conditioner running 8 hours a day can consume a large share of a household bill — which is why this calculator is the first step to an energy-saving plan: compare appliances, adjust usage hours, and see the saving instantly.
Use the tool to rank your appliances by monthly cost. The list usually shows ACs, heaters and water pumps at the top — and those are exactly the places where small behaviour changes deliver the largest savings on the next bill.
For the most accurate outcome from the Refrigerator Electricity Cost Calculator, keep the editable rates and defaults up to date with current figures before reading the result.
How to estimate an appliance's running cost
- 1
Enter the appliance's power rating in watts (printed on its label).
- 2
Enter the average hours it runs per day.
- 3
Enter your electricity tariff in PKR per unit, if different from the default.
- 4
Read the daily, monthly and annual cost, updated live.
Frequently Asked Questions
How is appliance cost calculated?
Consumption = watts × hours ÷ 1000 (kWh). Cost = kWh × your tariff (Rs/kWh). A 1,500 W AC running 6 hours at Rs 40/kWh costs Rs 360/day.
How do I find an appliance's wattage?
Check the rating label on the appliance or its manual — it is usually printed as watts (W) or kilowatts (kW). For example, a 1.5-ton inverter AC typically draws 1,200–1,500 W while running.
Which appliances cost the most to run?
Air conditioners, heaters, geysers, water pumps and old refrigerators dominate household bills. High-wattage appliances used for many hours cost the most — exactly what this calculator quantifies.
Do inverter appliances save money?
Yes — inverter ACs and fridges use variable-speed compressors that draw far less power at partial load, often cutting running costs by 30–50% compared with non-inverter models.
