Maliyet Formülü
Elektrik maliyeti, tüketilen enerjinin elektrik şirketinizin kWh başına fiyatıyla çarpılmasından ibarettir.
Günlük Maliyet
Cost = kWh × Rate ($/kWh) Herhangi bir cihazın veya sistemin günlük işletme maliyetini bulmak için günlük kWh tüketimini elektrik tarifenizle çarpın.
Yıllık Projeksiyon
Annual = Daily Cost × 365 Maliyetleri yıllıklandırmak, görünüşte küçük günlük harcamaların gerçek etkisini ortaya çıkarır ve enerji tasarrufu yükseltmelerini haklı çıkarmayı kolaylaştırır.
How to Calculate Your Electricity Cost
Understanding exactly what each appliance costs to run empowers smarter energy decisions — from choosing when to run the dishwasher to calculating the payback period on a new heat pump. The calculation is straightforward: find the power in kW, multiply by hours of operation, and multiply by your electricity rate per kWh.
Finding Your Electricity Rate
Your electricity rate ($/kWh or p/kWh) appears on your utility bill — look for "energy charge" or "unit rate." In the US, the average residential rate is around $0.12–$0.16/kWh, but it varies widely by state and time of day (time-of-use tariffs). In the UK, the Ofgem price cap sets a standard unit rate. Always use your actual rate for precise calculations.
Biggest Contributors to Your Electricity Bill
- Space Heating / Cooling (40–50%): Heat pumps are 3–4× more efficient than resistance heaters — replacing old electric baseboard heaters can cut this portion dramatically.
- Water Heating (15–20%): Heat pump water heaters use 60–70% less electricity than conventional electric tank heaters.
- Appliances and Lighting (10–15%): LEDs and Energy Star appliances provide the biggest savings here with shortest payback periods.
- Electronics and Standby (10%): Smart power strips and unplugging devices cuts phantom load — small savings that add up over a year.
Time-of-Use Pricing Tips
Many utilities offer time-of-use (TOU) tariffs with cheaper rates during off-peak hours (typically late night and early morning). Shifting energy-intensive tasks — EV charging, running dishwashers and laundry, pre-cooling your home — to off-peak hours can reduce your bill by 20–40% without reducing consumption at all.
