在线免费房贷计算器

This calculator shows principal and interest only. Your actual payment will also include property taxes and homeowners insurance (often called PITI — Principal, Interest, Taxes, Insurance), and private mortgage insurance (PMI) if your down payment is under 20%.

At a 6.5% interest rate on a 30-year loan with a 20% down payment, a $2,000/month payment corresponds to roughly a $315,000 home price. Use the calculator to reverse-engineer your target by adjusting the loan amount until the monthly figure matches your budget.

An amortization schedule shows how each payment is split between paying off principal and covering interest over the life of the loan. Early payments are mostly interest; later payments are mostly principal. The schedule here updates in real time as you change inputs.

A larger down payment reduces the financed amount, which lowers both your monthly payment and the total interest paid over the loan term. A 20% down payment also eliminates the need for private mortgage insurance (PMI), saving you further.

Yes. Enter the remaining balance of your current mortgage as the Loan Amount, input the new interest rate you've been quoted, and set the remaining or new term. The result shows what your refinanced monthly payment would be.
