A Skills Approach Excel 2013 Chapter 3: Using Formulas and Functions

In this assignment, you are tasked with completing a vehicle-shopping workbook designed to compare the purchase costs of several vehicles. The project involves applying various Excel skills including naming ranges, calculating averages, using lookup functions like VLOOKUP, working with named ranges, utilizing function arguments, employing logical functions such as IF, calculating loan payments with PMT, referencing data across worksheets, displaying and printing formulas, troubleshooting errors with trace precedents and dependents, identifying minimum and maximum values, using Formula AutoComplete, updating and managing named ranges through the Name Manager, and error checking.

The workbook includes data on different vehicle options with details such as prices, vehicle types, MPG, costs, and loan information. You will name specific cell ranges for easier reference, perform calculations for average MPG, registration fees, financing needs, monthly loan payments, monthly costs of gas, maintenance, and insurance, and determine vehicle affordability based on monthly budget constraints.

Additionally, you will create statistical analysis formulas using named ranges, ensure error-free worksheets, and prepare the workbook for submission. This project aims to strengthen your practical knowledge of Excel functions and data management within a multi-sheet workbook related to vehicle purchase analysis.

The comprehensive assessment of vehicle purchase options through Excel demonstrates the importance of mastering multiple functions and techniques to facilitate data analysis and decision-making. This paper details the process and skills involved in constructing and analyzing a vehicle purchase workbook, illustrating their roles in accurate and efficient financial evaluation.

The initial step involves setting up the workbook with relevant data, including vehicle prices, types, MPG figures, and costs such as maintenance, registration, insurance, and loan details. To streamline data management, naming ranges for key data tables like registration fees enhances formula readability and maintainability. The range "RegistrationFees" is created for this purpose, simplifying lookup references and modifications without editing individual formulas.

Calculating the average miles per gallon (MPG) for each vehicle is fundamental for estimating fuel costs. Using the AVERAGE function with a single argument, cells are filled with formulas computing these averages. Excel’s error alert may flag potential issues, but these are easily ignored with the SmartTag, assuming the formulas are correct. These MPG values serve as baseline fuel efficiency metrics crucial for subsequent cost calculations.

Registration fees vary depending on vehicle type. Using the VLOOKUP function, registration fees are retrieved from a dedicated table, with the vehicle type in C5 as the lookup value and the "RegistrationFees" named range as table array. Exact match is required to ensure accurate fee assignment. Applying this formula across vehicle entries ensures each vehicle's registration fee is accurately linked, facilitating fair comparisons.

The need for a loan depends on whether the vehicle's purchase price exceeds available cash. An IF function compares the price against the cash amount (A3 on the Assumptions sheet), returning "no" if the vehicle is affordable without financing and "yes" if it isn't. Absolute references are used to ensure formulas remain correct when copied across multiple vehicles.

Calculating the amount to borrow involves subtracting available cash from the vehicle price. An Excel formula employs absolute references for the cash amount, ensuring consistency as it is copied across the row of vehicles. This calculation informs the subsequent loan payment analysis.

Loan payments are computed using the PMT function, which considers interest rate, number of periods, and amount borrowed. The formula multiplies the number of years by 12 to convert to monthly payments, ensuring proper calculation of loan amortization. The PMT function is formatted to display the payments as positive numbers by adjusting the sign.

Fuel costs are an essential component of total monthly expenses. The formula divides the annual miles driven by the average MPG, multiplies by the cost per gallon, and uses absolute references for constants such as miles per month, MPG, and gas price, ensuring accuracy when copying formulas across vehicles. Error checking involves displaying formulas and tracing precedents if values appear unexpected or are zero.

Maintenance and insurance costs are calculated yearly and divided by 12 to determine monthly amounts. These formulas incorporate fixed costs, referencing cells on the Assumptions sheet for maintenance and insurance, and allow for quick adjustments across vehicle options.

The total monthly expense for each vehicle combines fuel, loan, maintenance, and insurance costs. Using simple addition formulas, these totals are computed, providing a comprehensive monthly cost overview. To assess affordability, an IF formula compares this total with the total monthly budget outlined in cell A4 of the Assumptions sheet, displaying "yes" or "no" accordingly.

To facilitate detailed analysis, the range of data is converted into named ranges via the Create from Selection feature, using labels for each row as their names. The Name Manager is reviewed to verify correct creation and naming conventions. Using Formula Autocomplete minimizes typing errors and ensures formulas link to the correct ranges.

Finally, prior to submission, the worksheet is thoroughly checked for errors using Excel’s built-in tools, and the workbook is saved and closed. The completed project showcases a solid understanding of how to leverage various Excel functions to evaluate vehicle purchase options comprehensively, assisting decision-making with data-driven insights.
