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.


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.

Sammamish Mortgage is extremely fast, experienced, and professional. They work around the clock to make sure you close when you need to. We closed over a week ahead of schedule on an already short timeline. I highly recommend doing business with them.

Sammamish set the high-water mark for mortgage experiences. Friends in the neighborhood recommended them. One of the best decisions of our entire home-buying process! Proactive and clear communication. Warm, kind, understanding, hard-working team of professionals. Fantastic technology that allows for easy to upload and review documents. The entire process felt like Sammamish was working with and for us and did so in a way that centered on relationships and care. They'll be our first call always.

We had a great experience with Sammamish! We shopped multiple lenders (NavyFed, Rocket, Envoy) and Sammamish had the most competitive rates. Ryan was very helpful and approachable for me as a first-time homebuyer and we will definitely use them in the future for our home lending needs.

My realtor was hearing great feedback from her clients, and she recommended that I reach out. I was just like you searching which lender to go with. Then you are in the right spot! They provide the best rates and service. Since the townhouse that I purchased was a new construction home, my process was complicated. But they were always there for you to clearly communicate. Ryan, Barb and all the staff members were so nice, knowledgeable, reliable, and professional. I really like that their website offers a tool to check rates timely. The end-to-end process for closing was very quick and smooth. I will go back to Sammamish Mortgage if I have another opportunity.


How can Sammamish Mortgage offer such low rates and fees?

Since 1992 Sammamish Mortgage has offered excellent service at very competitive rates and fees. Over this time, our proven track record and quality loans have helped us build exceptional relationships with the lenders that provide you with home loans. These relationships have been built on trust, integrity, and most of all, exceptional business practices. Our long standing business partnerships allow us the ability to offer unrivaled pricing on home mortgages. This pricing, in addition to utilizing top of the line technology and low overhead, enables us to pass the savings on to you, our clients.

We do not have a large team of loan officers. Instead we have a small team of highly experienced and trained professionals to handle your home loans.

When you show no points, does that also mean no origination fees and/or mortgage broker fees?

Yes. At Sammamish Mortgage you will find that anytime we offer or advertise no points, it assumes no origination fees. Many banks, credit unions and mortgage companies will advertise and offer no point loans on their website only to disclose later in the loan process or in fine print that there is a minimum 1% origination fee added to the loan. We feel that this is a deceptive practice and although it is legal, we feel strongly that it should not be allowed.

Do you guarantee your closing costs?

Yes. At the time of your pre-approval, we can guarantee all lender and 3rd party costs associated with your loan. Your costs may change if there is a valid change in circumstance such as a lower than expected appraised value, or if you decide to change your loan amount as your loan to value is a key factor in pricing your loan. Your loan specialist can go over all the different scenarios with you if you are unsure of your value on a refinance. We rarely have issues with the value on a purchase.

Who would benefit from choosing a loan with no points vs. paying points and/or origination fees?

Choosing a loan with 0 points/origination fees generally benefits the borrower for the first 4 to 7 years of the loan. This is because you exchange lower up front closing costs for a slightly higher interest rate and monthly payment. This is a great option for people that do not have excess liquid cash or emergency funds and people that are not sure how long they are planning on keeping the loan. Since most people either refinance or sell their home every 3 to 5 years, this plan can be of great value. When determining whether a no point, no origination fee and/or no mortgage broker fee loan would work for you, you have to carefully consider the following:

• How long you plan on staying in the property?

• Do you think that you might refinance in the near future?

• Do you have enough emergency funds saved to warrant paying higher up front costs?

If you are uncertain as to which is best for you, one of our loan specialists can assist you in making the decision that best suits your needs.

What are the main factors that can affect my interest rate?

There are several key points that can affect your rate. Below is a detailed breakdown of some attributing factors that may apply:

• Credit Score: Your credit score is one of the most important factors that will determine your rate.
• Loan to Value: Your down payment in a purchase transaction or your equity in a refinance transaction also plays a key role in determining your rate. The lower your loan to value (LTV), the better your rate may be.
• Rate/term refinance vs. Cash out refinance: A rate/term refinance has a loan amount that is just enough to repay the balance of your existing mortgage. You may include all third party fees, taxes, insurance and interest into the loan amount. A cash-out refinance, on the other hand, has a loan amount that exceeds your current mortgage balance.
• Purchase vs. Refinance: There are times when lenders offer purchase specials, which allow us to offer even lower rates than we already do.
• Property type: Often times there can be pricing adjustments for condos and multi-family properties.
• Escrow Reserve: Paying your property taxes and homeowners insurance on your own rather than having them included in your house payment may cost you an additional fee. Most lenders charge a onetime fee for the impound waiver.

• Loan amount: Your loan amount can affect your pricing. If you have a large loan amount (over $417,000) there will be pricing adjustments. If your loan amount is low, there can also be pricing adjustments generally starting at $165,000 and lower.

• Subordinate financing: Having a second mortgage or Home Equity Line of Credit tied to the property can impact the terms of the first mortgage even if no money is owed on the equity line. The line is still considered a lien against your property and impacts your Combined Loan to Value.

What can cause my loan to be considered a cash-out refinance?

The obvious trigger for a cash-out refinance is borrowing more than your existing loan balance; however, consolidating debt that was not obtained as part of the original purchase is also considered a cash-out refinance. This includes second mortgages or Home Equity Line of Credits opened after you purchased the property.
