Estimate your US monthly mortgage payment — principal, interest, taxes and insurance (PITI).
Calculate your monthly mortgage payment in the United States with home price, down payment, interest rate, loan term, property tax and home insurance. See the full PITI breakdown, total interest paid over the life of the loan and a year-by-year amortization chart for 15-year and 30-year fixed mortgages.
Use this free mortgage calculator to estimate your monthly home loan payment in the United States — including principal, interest, property taxes and homeowners insurance (PITI). Whether you are shopping for a 30-year fixed mortgage, a 15-year refinance or your first FHA loan, model different home prices, down payments and US interest rates side by side. The calculator works for conventional, FHA, VA and jumbo loans, and instantly shows your total interest paid, loan-to-value ratio and a year-by-year amortization chart so you can compare offers from any US lender with confidence.
M = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)
On a $300,000 home loan at a 6.5% fixed APR over 30 years, the monthly principal & interest works out to about $1,896. Add $300/mo property tax (1.2% annual) and $125/mo insurance and your total monthly PITI is roughly $2,321. Over the full 30-year term you’ll pay around $382,000 in interest — more than the home itself. Refinancing to a 15-year term at 6% raises the monthly P&I to ~$2,531 but slashes lifetime interest to about $156,000.
PITI stands for Principal, Interest, Taxes and Insurance — the four components most lenders include in a monthly mortgage payment estimate. The principal and interest portion repays the loan; taxes and insurance are typically collected into an escrow account and paid on your behalf.
Monthly P&I uses the standard amortization formula: M = P × r(1+r)^n / ((1+r)^n − 1), where P is the loan amount (home price minus down payment), r is the monthly interest rate, and n is the total number of months. Tax and insurance are added on top.
Conventional loans in the US typically require 5–20%; FHA loans accept as little as 3.5%. Putting down 20% lets you avoid private mortgage insurance (PMI) and lowers the loan amount, which lowers your interest cost over the life of the loan.
A 15-year term has a higher monthly payment but dramatically less total interest — often less than half. A 30-year term keeps the monthly payment manageable. Many buyers take the 30-year for flexibility and prepay when they can.
No. This calculator focuses on PITI (principal, interest, property tax and insurance). PMI, HOA dues, closing costs and points are not included — add them separately when comparing offers.
