Why Automate Your BBDBuy Spending Calculation?

Manual calculation of expenses is time-consuming and prone to errors. By automating the process with spreadsheet formulas, you can:

• Save time on data entry and calculations
• Reduce human error in totaling costs
• Get instant updates when you add new purchases
• Track your spending trends more effectively

Setting Up Your BBDBuy Spreadsheet

Create columns for the following data in your spreadsheet:

• Item Name: Description of purchased item
• Item Cost: Base price of the item
• Shipping Fee: Delivery charges
• Service Charge: Any additional fees
• Total Cost: Automatically calculated column

Automation Formulas for Total Spending

Excel Formulas

In the Total Cost column, use this formula to sum all cost components:

=SUM(B2:D2)

Where B2 is Item Cost, C2 is Shipping Fee, and D2 is Service Charge.

To calculate the grand total of all purchases, use:

=SUM(E2:E100)

Where E2:E100 represents your Total Cost column range.

Google Sheets Formulas

The formulas work similarly in Google Sheets:

=SUM(B2:D2)

For individual item totals, and:

=SUM(E2:E100)

For the overall spending total.

Advanced Automation Tips

Using Array Formulas (Google Sheets)

For automatic calculation across all rows without dragging formulas:

=ARRAYFORMULA(IF(B2:B="","",B2:B+C2:C+D2:D))

Conditional Formatting for Overspending

Highlight purchases exceeding your budget:

• Select your Total Cost column
• Go to Format     Conditional Formatting
• Set rule: "Greater than" your budget amount
• Choose highlighting color

Creating a Summary Section

Add a dashboard with key metrics:

Total Items: =COUNTA(A2:A100)
Total Spending: =SUM(E2:E100)
Average Cost per Item: =AVERAGE(E2:E100)
Highest Single Purchase: =MAX(E2:E100)
