Understanding Mortgage Calculations
A mortgage calculator helps you estimate your monthly home loan payments based on the loan amount, interest rate, and term length. The calculation includes principal and interest, and can also factor in property taxes, homeowners insurance, and PMI.
How Mortgage Payments Are Calculated
Your monthly mortgage payment consists of four main components (often called PITI):
- Principal: The amount borrowed that goes toward paying down your loan balance
- Interest: The cost of borrowing money from the lender
- Taxes: Annual property taxes divided by 12 months
- Insurance: Homeowners insurance and PMI (if applicable)
Factors That Affect Your Mortgage Payment
Several key factors determine your monthly payment amount:
- Loan amount and down payment size
- Interest rate (fixed vs. adjustable)
- Loan term (15-year, 30-year, etc.)
- Property taxes in your area
- Home insurance costs
- PMI if down payment is less than 20%
