Understanding Your Mortgage Payment
Your monthly mortgage payment consists of several components. The principal is the portion that reduces your loan balance. Interest is what the lender charges for the loan. Together, these make up the base payment calculated using standard amortization formulas. Property taxes are typically collected monthly by your lender and held in an escrow account. Homeowners insurance protects your property and is usually required by lenders.
The Mortgage Payment Formula
The standard formula for calculating a fixed-rate mortgage payment is: M = P × [r(1+r)^n] / [(1+r)^n - 1], where M is the monthly payment, P is the principal loan amount, r is the monthly interest rate, and n is the number of payments. This calculator automates this formula and provides a complete amortization breakdown.
Mortgage Tips to Save Money
Making even one extra payment per year can shave years off your mortgage and save thousands in interest. Consider a 15-year term if you can afford higher payments — the interest rate is typically lower and you will build equity much faster. Shop multiple lenders to compare rates, as even a 0.25% difference in rate can save you tens of thousands over the life of a 30-year loan. If your down payment is under 20%, you will pay PMI — saving up for a larger down payment can eliminate this extra cost.
