Electricity bill calculation for all devices:

First, you need to find the total electricity consumption, for that you can use your energy meter, by finding the initial and final reading.

Total energy consumption = Final reading –  Initial Reading.

Electricity bill = Total energy consumption * per unit cost.

Or

Technically, you can use the below-mentioned electricity consumption formula, Electricity consumption E(kWh) in kWh is equal to multiplication of power P(W) Watts and the Time period in a day divided by 1000.

E(kWh) = P(W) × t(h) / 1000(W/kW)

If your device is rated in kW means, you can use the below formula,

E(kWh) = P(kW) × t(h)

For month calculation,

E(kWh) = P(kW) × t(h) x 30

For yearly calculation,

E(kWh) = P(kW) × t(h) x 365

For hourly calculations,

E(kWh) = P(kW) × t(h)

Remember that 1 kWh is equal to one unit. It means if your device is running with 1 kW for an hour means, your device electricity consumption is 1kWh.

Electricity cost calculation:

The total electricity cost per hour in euro/rupees/dollar is equal to the multiplication of the energy consumption E in kWh and per kWh cost.

Cost(dollar) = E(kWh) × Cost(cent/kWh) / 100(cent/dollar)

Example:

Let us take an example of 1.5kW microwave oven operated for 20 hours calculate the electricity bill for the same with per unit cost is 0.15 $.

Use our formula,

E(kWh) = P(kW) × t(h)

Total electricity consumption = 1.5 * 20 = 30 kWh

Electricity cost is,

Cost(dollar) = 30 * 15 /100 = 4.5 $

Hence the totally you have to pay 4.5 USD as electricity bill.

By using our electricity bill calculator, you can get the same results.
