Building a Deck: Calculating Total Costs with Taxes
As A. Leigh prepares to build a deck in her backyard, she needs to consider the total cost of the materials required for the project. In this article, we will create an interactive Excel spreadsheet to calculate the total cost of the supplies before taxes and after taxes, assuming a given tax rate.
Supply List for the Deck
Before we dive into creating the Excel spreadsheet, let's take a look at the supply list for the deck:
| Material | Quantity | Unit Price |
|---|---|---|
| Lumber | 100 | $5.00 |
| Decking Screws | 500 | $2.50 |
| Decking Nails | 200 | $3.00 |
| Wood Glue | 1 | $10.00 |
| Power Drill | 1 | $50.00 |
| Measuring Tape | 1 | $5.00 |
| Safety Glasses | 1 | $10.00 |
| Work Light | 1 | $20.00 |
| Total |
Creating the Excel Spreadsheet
To create the interactive Excel spreadsheet, we will use the following steps:
- Open a new Excel spreadsheet and create a table with the following columns: Material, Quantity, Unit Price, and Total Cost.
- Enter the supply list data into the table.
- Create a formula to calculate the total cost of each material by multiplying the quantity and unit price.
- Create a formula to calculate the total cost of all materials by summing up the total cost of each material.
- Create a formula to calculate the tax amount by multiplying the total cost by the tax rate.
- Create a formula to calculate the total cost after taxes by adding the tax amount to the total cost.
Formulas and Functions
Here are the formulas and functions used in the Excel spreadsheet:
| Formula | Description |
|---|---|
| =B2*C2 | Calculate total cost of each material |
| =SUM(D2:D7) | Calculate total cost of all materials |
| =E2*F2 | Calculate tax amount |
| =G2+H2 | Calculate total cost after taxes |
Interactive Excel Spreadsheet
Here is the interactive Excel spreadsheet:
| Material | Quantity | Unit Price | Total Cost | Tax Rate | Tax Amount | Total Cost After Taxes |
|---|---|---|---|---|---|---|
| Lumber | 100 | $5.00 | $500.00 | 8% | $40.00 | $540.00 |
| Decking Screws | 500 | $2.50 | $1,250.00 | 8% | $100.00 | $1,350.00 |
| Decking Nails | 200 | $3.00 | $600.00 | 8% | $48.00 | $648.00 |
| Wood Glue | 1 | $10.00 | $10.00 | 8% | $0.80 | $10.80 |
| Power Drill | 1 | $50.00 | $50.00 | 8% | $4.00 | $54.00 |
| Measuring Tape | 1 | $5.00 | $5.00 | 8% | $0.40 | $5.40 |
| Safety Glasses | 1 | $10.00 | $10.00 | 8% | $0.80 | $10.80 |
| Work Light | 1 | $20.00 | $20.00 | 8% | $1.60 | $21.60 |
| Total | $2,485.00 | $196.80 | $2,681.80 |
Calculating Total Costs with Taxes
As we can see from the interactive Excel spreadsheet, the total cost of the supplies before taxes is $2,485.00. The tax rate is 8%, so the tax amount is $196.80. Therefore, the total cost after taxes is $2,681.80.
