How mortgage payments are calculated

Your monthly payment is determined by three factors: the loan amount (home price minus your down payment), the annual interest rate, and the loan term. The standard amortization formula spreads your total cost across equal monthly payments — each covering both interest and a portion of the principal.

In the early years, most of each payment goes toward interest. As the balance decreases, more goes to principal. The amortization table above shows the exact breakdown for every month of your loan.

Frequently asked questions

How is my monthly mortgage payment calculated?
Your payment uses the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^nāˆ’1], where P is the loan amount, r is the monthly interest rate, and n is the number of monthly payments.
What is not included in this mortgage calculator?
This calculator shows principal and interest only. It does not include property taxes, homeowner's insurance, PMI (private mortgage insurance), or HOA fees.
What is mortgage amortization?
Amortization is paying off a loan through regular scheduled payments. Early payments cover mostly interest; later payments cover mostly principal. The full schedule is shown in the amortization table.
How much house can I afford?
A common guideline is to keep total housing costs (principal, interest, taxes, and insurance) below 28% of your gross monthly income. Your total debt payments should stay below 36%.
