PROJECT 2 – MORTGAGE CALCULATOR

Due Date: Midnight, Friday 21 September 2018 Weighting: 30%
Type: Individual
Submission: Electronic Submission via AUT Online

Instructions for the Project

Students are required to build a mortgage calculator in Excel 2016. The calculator should have the following features:

  • It should be capable of calculating the maximum amount a home-buyer can borrow, based on the user’s choice of preferred output. The appropriate inputs should include but not limited to: family incomes and assets, living expenses and debts, and regulations on deposit of residential property loan.
  • It should allow users to calculate the value of the outputs based on one of three different types of mortgage

    o Normal Mortgage
    o Growing Annuity Mortgage (payments grow at a constant rate over

    the life of the mortgage aka a growing annuity)
    o Interest Only Mortgage (payments cover only the interest

    component until the final payment which covers the entire principle

    of the mortgage)

  • The calculator should be capable of dealing with payments occurring over

    varying payment frequencies

  • The calculator should contain an amortisation table with at a minimum the

    following columns (payment, interest component of the payment, principle

    component of the payment and principle balance)

  • The calculator should be capable of dealing with items such as loan

    processing fee/low equity margin.

  • The calculator should contain a graph breaking down payments
  • The calculator should follow the rules of good financial model design.

    Students are expected to be able to explain or demonstrate any features or techniques in their assignments if requested.
