A basic mortgage calculator estimates principal and interest using the amount borrowed, the interest rate, and the number of monthly payments.
Loan amount is not always home price
If a home costs $400,000 and you make an $80,000 down payment, the starting loan amount is generally $320,000 before considering any financed fees.
Principal and interest are only part of housing cost
Property taxes, homeowners insurance, mortgage insurance, HOA fees, maintenance, utilities, and other costs can materially change the monthly budget.
Term changes the tradeoff
A longer term often lowers the required monthly principal-and-interest payment, but the loan can accrue interest over more years. A shorter term can do the opposite.
