Mortgage calculators that actually calculate.

Your monthly mortgage payment is made up of four parts, often called PITI: principal, interest, taxes, and insurance. Use the Monthly Payment calculator above: enter the home price, your down payment, the interest rate, and the loan term, and it estimates your full monthly payment and shows how much goes to each part. It's a free estimate for planning — your real payment depends on your actual rate, property taxes, and insurance.

A common rule lenders use is the 28/36 guideline: your monthly housing payment should stay under about 28% of your gross monthly income, and all your monthly debts combined under about 36%. Enter your income, monthly debts, and down payment in the Affordability calculator above and it estimates your maximum home price. It's an estimate — a lender reviews your full file to confirm what you actually qualify for.

An amortization schedule shows how each monthly payment splits between interest and principal over the life of your loan. Early on, most of your payment goes to interest; over time it shifts toward principal until the balance reaches zero. The Amortization calculator above shows your remaining balance year by year and the point where principal overtakes interest.

Refinancing can make sense when a new rate lowers your monthly payment enough to cover the cost of refinancing within a reasonable time. The Refinance calculator above compares your current loan to a possible new rate and estimates your monthly and lifetime savings. It doesn't include closing costs to refinance, so ask us for your true break-even point before deciding.

Paying a little extra toward principal each month can shave years off your loan and save a large amount of interest. The Extra Payment calculator above shows exactly how many years and how much interest you'd save for any extra amount you enter — often tens of thousands of dollars over a 30-year loan.

On a conventional loan, private mortgage insurance (PMI) automatically terminates once your loan balance reaches 78% of the home's original value, and you can request cancellation earlier, at 80%. The smaller your down payment, the longer that takes. The Down Payment & PMI calculator above estimates when PMI falls off based on your down payment, rate, and term. With 20% or more down, you usually avoid PMI entirely.

They give helpful estimates for planning and are based on standard mortgage math, but they're only as accurate as the assumptions you enter and can't account for your full financial picture. They are not a quote or an offer of any specific rate, payment, or terms. For real numbers tailored to you, talk with us directly — we'll shop hundreds of lenders and give you a straight answer.
