- Power = 2000
- Hours per day = 1
- Days per year in use = 365
- Electricity price = 0.28
- Standby power = 1
- Grid carbon intensity = 250
- kw = 2000 / 1000 = 2
- daily_kwh = 2 * 1 = 2
- standby_kwh = 1 / 1000 * (24 - 1) = 0.023
- Energy per day = 2 + 0.023 = 2.023
- Energy per year = 2.023 * 365 = 738.395
- Cost per day = 2.023 * 0.28 = 0.566 44
- Cost per year = 738.395 * 0.28 = 206.751
- Cost per month = 206.751 / 12 = 17.2292
- Cost per hour of use = 2 * 0.28 = 0.56
- Carbon dioxide per year = 738.395 * 250 / 1000 = 184.599
- Annual cost of standby alone = 0.023 * 365 * 0.28 = 2.3506
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- daily energy = power in kW x hours
- annual cost = daily energy x days x price per kWh
Nameplate wattage is the maximum draw, not the average. A cycling appliance like a fridge or a freezer averages far less.
Standby draw is small per device and adds up across a house: ten devices at 2 W each is 175 kWh a year.
