Oven Electricity Cost Calculator
Calculate the electricity cost of an electric oven or toaster oven.
About the Oven Electricity Cost Calculator
Built for Pakistani users, the Oven Electricity Cost Calculator turns a fiddly manual calculation into a one-glance result you can trust for planning and everyday decisions.
Running an air conditioner, heater, refrigerator or other appliance has a monthly cost that is easy to underestimate. This Oven 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.
Use the Oven Electricity Cost Calculator as often as you like — it is free, needs no account, and pairs well with the other calculators in this category for a fuller picture.
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

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.
