Introduction to Electricity Cost Calculator in Excel
The energy cost calculator is a straightforward tool for determining the cost of energy used by homes and businesses. By using the results of this calculation, you can establish a budget. Additionally, this power cost calculator assists in creating family or workplace budgets and managing expenses. The equation for calculating the cost is as follows:
Where:
 W = Power (Watts)
 H = Time (Hours)
 R = Rate (KWH)
In this article, weâ€™ll explore how to use SUM, IF functions, and Excel formulas for this calculation. Weâ€™ll also manually verify the calculator. Letâ€™s proceed step by step.
Step 1: Basic Information of the Electricity Cost Calculator in Excel
 Add the following headers in column B: User, User Address, and Pay Per Unit.
 Populate these headers with the correct values.
 Add additional headers: Home Appliance, Quantity, Power Rating, Total Watts, Hours/Day, Daily Cost, Monthly Cost, Yearly Cost, Total Electricity Cost, and Tax (3%).
 Fill in the appropriate values under Quantity, Power Rating, and Hours/Day.

Step 2:Â Using Excel Formulas to Calculate Daily, Monthly & Yearly Power Bills
Calculate the total Watts used for each appliance:
 In cell E9, enter the formula:
=C9*D9
Â

 Here, we multiplyÂ Power RatingÂ byÂ QuantityÂ to get the total Watts.
 PressÂ Enter.

 Autofill this formula for the rest of the column.
 Calculate the daily cost:
 In cell G9, use the formula:
=(($C$6/1000)*F9*E9)*1

 Here, we divide the Pay per Unit 0.80 by 1000 and multiply it by 450 & 8.
 Lastly, we multiply by 1 as we wish to get the daily cost.
 Press Enter.

 Autofill this formula.
 Calculate the monthly cost:
 In cell H9, use the formula:
=(($C$6/1000)*F9*E9)*30

 Press Enter.
 Autofill this formula.
 Calculate the yearly cost:
 In cell I9, use the formula:
=(($C$6/1000)*E9*F9)*365

 Press Enter.

 Autofill this formula.
 Use the absolute cell reference in C6 as we do not wish to change the cell.
Step 3:Â Estimating Total Electricity Cost with the SUM Function
 To estimate the total daily cost, use the SUM function in cell G17:
=SUM(G9:G16)

 Press Enter.
 Similarly, calculate the total monthly cost in cell H17:
=SUM(H9:H16)

 Press Enter.
 For the yearly cost, use the SUM function in cell I17:
=SUM(I9:I16)

 Press Enter.

Step 4:Â Adding Tax Using the IF Function
Calculate Tax for Daily Cost (Cell G18):
 In cell G18, use the following formula:
=IF(G17>33,G17+G17*3%,G17)

 Explanation:
 If the value in G17 (daily cost) is greater than 33, add a 3% tax to it.
 Otherwise, keep the original daily cost.
 Explanation:
 Press Enter.
Calculate Tax for Monthly Cost (Cell H18):
 In cell H18, use this formula:
=IF(H17>1000,H17+H17*3%,H17)

 Explanation:
 If the value in H17 (monthly cost) exceeds 1000, apply a 3% tax.
 Otherwise, retain the original monthly cost.
 Explanation:
Calculate Tax for Yearly Cost (Cell I18):
 In cell I18, use the following formula:
=IF(I17>12000,I17+I17*3%,I17)
 Press Enter.
