Factors That Affect Mortgage Payments
Interest Rate

Loan Amount
Borrowing more increases overall repayment expenses.
Down Payment
Larger down payments reduce monthly mortgage obligations.
Loan Term
Longer terms lower monthly payments but increase total interest.
Property Taxes and Insurance
These costs significantly impact total monthly housing expenses.
Understanding Principal and Interest
Principal
The principal is the original amount borrowed from the lender.
Interest
Interest is the cost charged by the lender for borrowing money.
In the early years of a mortgage, a larger portion of payments goes toward interest rather than principal.
What Is PMI?
Private Mortgage Insurance
PMI is usually required if the borrower makes a down payment below 20%.
Purpose of PMI
It protects the lender if the borrower defaults on the loan.
Removing PMI
PMI may be removed once sufficient home equity is reached.
The calculator can help estimate PMI costs if applicable.

The calculator allows users to compare both options.
