How the mortgage calculator works

Your monthly payment has two parts. Principal and interest is fixed for the life of a fixed-rate loan and is calculated with the standard amortization formula:

M = P × r ÷ (1 − (1 + r)−n)

where P is the amount you borrow, r is the annual rate divided by 12, and n is the number of payments (360 for a 30-year loan). On top of that, most lenders collect property tax and homeowner's insurance through escrow, plus PMI if you put less than 20% down on a conventional loan. Together these are called PITI.

Monthly payment by loan amount (30-year fixed)

Principal and interest only — add taxes, insurance and PMI for your full payment.

Loan amount6.0%6.5%7.0%
$200,000$1,199$1,264$1,331
$300,000$1,799$1,896$1,996
$400,000$2,398$2,528$2,661
$500,000$2,998$3,160$3,327

How to lower your mortgage payment

  • Put 20% down to avoid PMI, which typically costs 0.5–1.5% of the loan per year.
  • Raise your credit score before applying — 740+ usually gets the best rates. See what credit score you need to buy a house.
  • Shop at least three lenders. Rates and fees vary, and comparing Loan Estimates can save thousands.
  • Appeal your property tax assessment if it's higher than comparable homes — learn how property taxes work.
  • Consider a lower price. Every $10,000 less you borrow at 6.5% saves about $63 a month.

Should you make extra payments?

Extra payments go straight to principal, so they cut both your loan term and total interest. Whether it's the best use of your money depends on your rate: above roughly 6.5%, prepaying is a strong guaranteed return; below about 5%, investing has historically earned more.

Frequently Asked Questions

Principal and interest use the formula M = P × r ÷ (1 − (1 + r)^−n), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly payments. Your full payment (PITI) adds monthly property tax, homeowner's insurance, PMI if you put less than 20% down, and any HOA dues.
At 6.5% for 30 years, principal and interest on a $300,000 loan is about $1,896 per month. Property tax, insurance and PMI typically add $400–$700 more depending on where you live.
A 15-year mortgage has a higher payment but a lower rate and far less total interest — often less than half. A 30-year mortgage keeps the payment lower and more flexible. Many people take a 30-year loan and make extra payments when they can.
On a $300,000, 30-year loan at 6.5%, paying an extra $500 a month pays the loan off about 12½ years early and saves roughly $180,000 in interest. Use the extra payment field above to see your own numbers.
On a conventional loan, PMI automatically ends when your balance reaches 78% of the home's original value, and you can request removal at 80%. FHA mortgage insurance usually lasts for the life of the loan unless you put at least 10% down.
Lenders generally want total housing costs under 28% of gross monthly income and all debts under 36%. On $100,000 a year, that's about $2,330 a month for your full mortgage payment including taxes and insurance.
