Understanding Your Mortgage
This mortgage calculator helps you estimate your monthly home loan payment, total interest costs, and shows a detailed amortization schedule. Understanding these figures is crucial for budgeting and making informed financial decisions when buying a home.
Principal & Interest
Your monthly payment primarily consists of principal (paying down the loan amount) and interest (the cost of borrowing). Early in the loan, most of your payment goes toward interest.
Impact of Down Payment
A larger down payment reduces your loan amount, monthly payment, and total interest paid. Putting down 20% often avoids Private Mortgage Insurance (PMI).
Loan Term Trade-offs
A shorter term (e.g., 15 years) means higher monthly payments but significantly less interest paid over the life of the loan compared to a 30-year term.
How Mortgage Payments Are Calculated
The standard formula used by this calculator is the amortization formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
Where:
M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate ÷ 12)
n = Total number of payments (loan term in years × 12)
This formula calculates a fixed monthly payment that ensures the loan is paid off in full, with interest, by the end of the term.
