Q1: What factors affect the principal amount calculation?
A: The principal amount is determined by three main factors: monthly payment amount, interest rate, and loan term. Higher payments, lower rates, or longer terms result in higher principal amounts.
Q2: Does this calculation include taxes and insurance?
A: No, this calculation only considers principal and interest. For a complete mortgage payment estimate, you should add property taxes, insurance, and any HOA fees.
Q3: How does interest rate affect the principal amount?
A: Lower interest rates allow you to borrow more money for the same monthly payment, while higher rates reduce the amount you can borrow.

Q5: Should I consider additional costs beyond the principal?
A: Yes, you should also budget for closing costs, moving expenses, home maintenance, and potential renovations when determining your overall housing budget.
