Bill-budgeting is a crucial part of being fiscally responsible. Even if you can easily pay off your monthly bills, there is no harm in paying attention to __energy usage__ and to make sure that the bills are accurate.

Accurately estimating an __electricity bill__ requires you to find how much each device and appliance in your house is used. Thankfully, finding this out is not as difficult as it seems.

## Calculating Electricity Usage:

As we mentioned, the first step in this calculation is determining the amount of electricity watts every device and appliance in your house is consuming. This can be calculated by the following formula: **The appliance/device wattage x number of hours that the device/appliance is used daily. **

However, this formula will result in a ‘watt-hours’ answer and, in order to convert it to kilowatt-hours, you need to divide the answer by 1,000 (this is because 1,000 watts = 1 kilowatt). Hence, by dividing the watt-hours number by 1,000, you will be able to learn the per-day kWh usage of the device or appliance.

The next step is to calculate the per-month usage – this requires multiplying the per-day kWh number by 30 (this is because a month, on average, has 30 days). So, the formula for monthly usage is: **kWh per-day usage x 30**.

## Calculating Electricity Costs:

Calculating the __electricity__ cost for a device or appliance will require you to take the kWh monthly usage (discussed above) and multiply it by the electricity rate specified by your electric plan and/or utility company.

The formula for calculating the electricity cost would be: **kWh monthly usage x monthly electricity rate ($/kWh). **

For those on variable tariffs, calculating the electricity cost might be considerably trickier. Therefore, we recommend using a usage monitor which provides an estimated monthly cost.

## Calculating Cost per kWh:

In order to calculate the per __kWh cost__, you will need to find out your specific electric rate, and the wattage of your device or appliance (this can often be found on the item itself; if not, you should be able to find it through Google).

Once you have the above two numbers, use the following formula:

(Appliance or device wattage x per day use (in hours) ) / 1,000 x per kWh electric rate.

The answer would be your per kWh for the particular appliance or device.
