The challengešŸ¤ŗ

Here’s the scenario to be solved from the download file:

We want to buy a house and need to ask the bank for a loan of $400,000. 

The bank offers the following loan terms:

  • Loan Amount: $400,000.
  • Interest Rate: 4.25% (per annum).
  • Payment Period: 30 years.
  • Payment Due: End of the month.

Our monthly budget for this loan is $2500.00. 

Part 1: Calculate the monthly payments

We need to calculate our monthly repayments to see if we can realistically afford the loan and if it falls within our budget. 

Note the following:

  • All calculations must be monthly, not yearly. 
  • We are not making a bulk payment (future value) at the end of the loan to clear the balance down to zero.
  • The monthly payment should be displayed as a positive value.

Part 2: Recalculate the loan

Once we have performed this calculation, we can see that it falls below our monthly budget. 

Use What-If Analysis tools to work out how much more money we could afford to borrow from the bank if we were paying our maximum budget value of $2500.00 per month.
