Understanding These Examples

Key factors that influence mortgage calculations

Interest Rate Impact

Even small changes in interest rates significantly affect monthly payments and total interest paid over the life of the loan.

Down Payment Benefits

Higher down payments reduce monthly payments, eliminate PMI, and decrease total interest costs.

Loan Term Effects

Shorter terms mean higher monthly payments but significantly less total interest paid over the life of the loan.

PMI Considerations

Private Mortgage Insurance is required for down payments under 20% and adds to your monthly costs.
