Common Mortgage Calculator Terms

You can use our mortgage payments calculator to provide yourself with information about the estimated monthly mortgage payments you’ll make on a new home, with the option to include your anticipated tax, insurance and PMI costs. The following types of information can be entered into the mortgage calculator to give you the best results:

By Home Price

Work forward based on the price of the home you want to figure out your best loan term and potential monthly payment.

By Affordability

Use your down payment and monthly budget to discover how much home you can afford, then save up to $3000 by comparing top lender quotes.

By Monthly Payment

Input your monthly payment to discover what kind of loan will work best for you, then fill out an application with a lender to verify the estimate.

Bi-Monthly Payment

Pay every other week instead of once a month and save thousands over your loan term by reducing the principal amount quickly.

Home Price

You can input the amount you plan to offer for the home of your dreams or run the numbers based on the home list price.

Down Payment

Take your savings, deduct the amount you’ll need for closing costs, and what’s left will serve you as a down payment.

Interest Rate

Remember that your interest rate will vary depending on the lender you choose, your loan program, and your credit score.

Loan Program

Depending on the type of loan you get (FHA, VA, USDA, or conventional), your finances will be impacted differently.

Property Tax

The assessed value of the home multiplied by the local tax rate will give you the estimated amount of your property tax.

Home Insurance

Home value and location will both impact how much you will have to pay for home insurance to protect your investment.

Monthly Private Mortgage Insurance

You’ll need to pay PMI ranging from 0.5% to 2% of the loan amount if your down payment amounts to less than 20% of the home price.

HOA Dues

A homeowners association (HOA) will charge monthly or annual dues, so find out if your home is located in an affected neighborhood.

Additional Principal Payment

If you can make a larger than required payment every month, the additional funds can go to reduce your loan principal.

Annual Income

Divide your annual income by 12 months to arrive at the monthly income that will be used when determining your ability to repay.

Monthly Debts

Add all recurring expenses or payments that you owe every month (like credit card bills or auto loan payments) to arrive at your monthly debt.

DTI

Compare your monthly income and monthly debt to find out what your debt to income (DTI) ratio is, the lower this number is, the better.

Desired Monthly Payment

A bigger monthly payment means you’ll pay off your loan more quickly, cutting years and interest costs off your mortgage.

Biweekly Payments

If you make half of a mortgage payment every other week, it works out to a whole extra mortgage payment every year.

Estimated Payoff

Ask your mortgage company to provide you with your amortization schedule so you can learn your estimated payoff date.

Ryan Shane and Shawn Keegan from Sammamish Mortgage were simply awesome to work with throughout this process! I originally started with Chase Bank but decided to go with Sammamish Mortgage for the personal touch. When I first contacted Ryan, he took the time to explain aspects of the process I had never even considered. It was a great decision. Working with their team was an amazing experience from start to finish. They are super professional, highly proficient, and provided zero surprises. Their guidance made the entire process clear and easy.

I cannot recommend Sammamish Mortgage enough!!!!! Jessica Ebner and Barb Kite were AMAZING and so helpful for a first-time home buyer who was unfamiliar with the process. The rates they offered were also very competitive and the transaction was smooth/pleasant throughout. I would recommend them to friends/family ANY DAY. Closed on time with no issues and I am now officially a homeowner! THANK YOU

I had a fantastic experience working with the team at Sammamish Mortgage for my recent home purchase. Barb and Trevor went above and beyond to make sure everything went smoothly. They provide a level of dedicated, personalized service that you just won't find with big box lenders. Because they handle their loan underwriting completely in-house, the entire process was so much easier, faster, and more streamlined than dealing with a massive bank. I highly recommend Sammamish Mortgage to anyone looking to purchase or refinance a home!

My partner and I had a great experience with Dave Walz and the rest of the team at Sammamish Mortgage. I can't recommend them highly enough! They really went above and beyond for us, and were able to make our home buying dreams a reality. We wouldn't work with any one else again in the future.
