S308 Assignment 5 – Car Loan Calculator
The Kelley Car Company wants to create an application to help potential customers calculate and
understand the car loan options they have available. The application must allow a user to enter the
amount of the desired loan, an interest rate, and the term of the loan then calculate the monthly
payment. Customers have also requested to know the total cost and total interest they should expect.
Kelley Car Company has mocked up an interface of what they think the application might look like
which is provided below. Consider this to be a starting place and good illustration of the information
and functionality they expect in the end product.
Important!
This is an individual assignment. Students are NOT allowed to work together or seek help from
anyone else including current and former S308 students. Any questions about the assignment
should be sent to the instructor. Anyone found to have received help from another person will
receive a zero (0) for the assignment and will be reported for academic misconduct.
Requirements:
The purpose of this assignment is to practice object oriented programming and integrate our new
skills with creating desktop applications. Accordingly, you will need to do the following:
1. Create the GUI with a) input controls for the 3 loan parameters (principal in USD, interest
rate, and term in months), b) a button that calculates the desired output and a clear button,
and c) a group of output controls for the calculated variables (payment, total cost, interest).
2. Create a class Loan with a) 3 properties for the loan parameters (along with their
corresponding get and set accessors) and b) 3 methods to calculate the variables called
CalcPayment, CalcTotalCost, and CalcInterest that take no input arguments and return a
double with the calculated results.
3. When your Calculate button is clicked, your program a) instantiates an object from the Loan
class with the input parameters from the user, b) calculates the output variables using the
classes methods (storing them in variables), and c) outputs the values of the calculated
variables to the GUI.

Monthly Payment
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
M = monthly payment
P = principal
i = monthly interest (interest rate / 12)
n = number of months
Total Cost
TC = M * n
Total Interest
TI = TC – P
