You want to buy a house financed with a 15-year fixed-rate mortgage. The best interest rate you could find is 7% APR. Payments are made monthly, so the APR should be assumed to be a simple interest rate (i.e. a stupid interest rate) added up over 12 months.
What is the most you can borrow if you can only afford to pay $1,800 per month?
We are given the following information:
Monthly payment | PMT | 1800.00 |
Rate of interest | r | 7.00% |
Number of years | n | 15.00 |
Monthly compounding | frequency | 12.00 |
Loan amount | PV | To be calculated |
We need to solve the following equation to arrive at the required PV
So the maximum loan amount possible is 200260.72
Below is the amortization schedule:
Opening balance = previous year's closing balance
Closing balance = Opening balance-Principal repayment
PMT is calculated as per the above formula
Interest = 0.07 /12 x opening balance
Principal repayment = PMT - Interest
