How to Calculate Your Mortgage Payment

Three main factors determine your monthly mortgage payment: the size of your loan, your interest rate, and the length — or term — of your loan. Your credit score and your home’s location will also affect your interest rate and, in turn, how much you pay. Lastly, additional expenses such as homeowner’s association fees and mortgage insurance should be factored in with your monthly housing expenses.

Mortgage Calculator 101

Our mortgage calculator can help you determine if you can realistically afford a home you have your eye on. If you’re at the start of your search, it allows you to see how different inputs — home price, credit score, interest rate, and down payment size — might impact your monthly payment and help you determine how much home you can comfortably afford.

Keep in mind that mortgage rates change every day and vary from lender to lender, so use this calculator to get a ballpark estimate and then make sure to get quotes from multiple lenders. (We recommend one of the top mortgage lenders of the year.) Once you start actively looking for a home, make sure to get pre-approved, so you can move quickly once you find a home you want to bid for.

To see your estimated mortgage payment, you will need to input the following values:

  • Your starting mortgage balance will be the price you pay for the house minus your down payment
  • Down Payment: Putting 20% down allows you to avoid paying for mortgage insurance. More equity also gives you more financing options down the road, but the average down payment is about 6%, and it is possible to secure a loan with as little as 3% down. With our calculator, you can enter the portion of the home’s cost you plan to pay upfront either as a percentage or a dollar value.
  • Interest Rate: This is the cost of your loan. Interest on a mortgage is calculated monthly. Our calculator will auto-populate with an average mortgage rate based on the information you enter, but you can override this to see how rate changes could impact your costs.
  • Zip Code: Your location can impact your mortgage rate.
  • Loan Type: The most common mortgage is a 30-year fixed-rate conventional loan, but some people opt for 15-year loans to pay off debt faster or adjustable rate loans to snag a lower rate. In most of the country, if your mortgage is larger than $510,400 you’ll need to take out a jumbo loan.
  • Credit Score: An estimation of your credit health. Fair (580-669), Good (670-739), Very Good (740-799), and Excellent (800 and above).

How Your Mortgage Payment Is Calculated

While our calculator takes the computing out of your hands, math whizzes can do so with the following formula:

M = P*[(i/12*(1+i/12)n)]/[(1+i/12)n-1]

M – your monthly mortgage payment

P – the principal loan amount

i – the interest rate, which should be divided by twelve (corresponding to the months of the year) since lenders give an annual rate

n – the number of payments over the life of the loan. For instance, for a 30-year mortgage, n would be 360 payments, (12 payments a year over 30 years, or 12*30).

How Mortgage Interest Rates Changed in 2020

As the economy came to a halt in March of 2020 due to the Coronavirus pandemic, the Federal Reserve cut short-term interest rates to zero. This move led average mortgage rates to drop below 3% for the first time. This also caused multiple record lows, as well as a boom in home sales and refinance applications that’s still going strong.

Despite the low rates, the housing market is not without its challenges. A shortage of new listings has led to bidding wars and rapidly rising prices in many places across the U.S. Meanwhile, increasing unemployment rates have driven lenders to adopt more stringent qualification requirements, keeping mortgages out of reach for many.

In light of these developments, potential homebuyers who already have their eyes set on a property should act fast, especially if they’re well-positioned to get the lowest mortgage rate.

How To Lock in the Lowest Mortgage Rates in History

Before applying for a mortgage, we suggest you follow these steps:

  1. Get loan estimates from different lenders and compare offers by APR.
  2. Keep track of these offers in a spreadsheet to easily see them side by side. Aside from the advertised rate, consider appraisal fees, property taxes, potential penalties, insurance, and any other closing costs. All lenders are required to disclose these numbers as part of your Loan Estimate, a form they must provide you within three business days of receiving your loan application. Since all lenders follow the same form, comparing all the numbers to find the offer that best suits your needs should be simple. After you select a lender, make sure to get pre-approved, so you can act quickly when you find a home you want to buy.
  3. Consider getting a rate lock once you’ve accepted an offer. These can help you secure a low rate during a specified timeframe (30, 45, 60 days) or until the mortgage’s closing. If your lock expires before closing, some lenders offer to extend it at no cost, while others might charge a fee. Read up on all these details to have a full picture of a lender before deciding to begin this process with them.

Understanding Mortgage Payments

Interest Rates

Your mortgage rate will play a vital role in determining your monthly payment. Interest rates are influenced by several factors. One of them is your credit score — the lower it is, the higher the interest you’ll pay on your loan. A low credit score represents a risk, and your rates will go up to compensate for being seen as a high-risk borrower.

The loan type you choose will also affect your rates. A shorter, 15-year loan represents less risk than a 30-year one. Likewise, whether you choose a fixed-rate or adjustable-rate will also have an impact. Furthermore, the down payment amount you can afford will be important in determining the interest rate you end up locking in.

Down Payments

Speaking of down payments, if you put less than 20% of the home value upfront, you’ll need to pay private mortgage insurance (PMI). This type of insurance may cost upwards of 3% of the loan amount per year. It’s worth noting that this insurance is put in place to protect the lender, not the borrower. The only exception to this would be an FHA loan, which does not require private mortgage insurance.

Mortgage Points

One way to lower your interest rate and, as a result, your monthly payment is to buy mortgage points from your lender at closing. These points are fees that essentially buy you a lower interest rate. The cost of each mortgage point is 1% of the loan’s total value.

Mortgage Calculator FAQs

What’s the best loan term for my mortgage?

More than 90% of mortgages are 30-year conventional loans. Still, you may find that a 15-year fixed-rate mortgage suits you best because you’ll pay less interest over the life of the loan — though you will have higher monthly payments.

How much should my down payment be?

In general, lenders require a minimum down payment of at least 3% of the home price. To avoid paying private mortgage insurance — which protects the lender, not the homeowner — borrowers will usually need to put 20% down (though low-downpayment, no-PMI options exist for qualified borrowers). The average homeowner pays a down payment of between 3% and 7%.

Can my monthly payment change over the life of the loan?

If you take out a fixed-rate loan and do not refinance, your monthly payment will stay the same for the entire loan term. If you opt for an adjustable-rate mortgage, your payment will stay the same for a set period, commonly five or seven years. Once that time is up, your mortgage rate resets annually based on market conditions, sending your monthly payment up or down. The risk of a higher rate later is why it only makes sense to get an adjustable-rate mortgage if you plan to move or refinance before the fixed term is up.

If you refinance to a lower mortgage rate, your monthly payments will go down. If you refinance to a shorter loan term, they will go up.

How accurate are the estimates in this calculator?

Rates are very individualized and are based on your specific circumstances, such as credit score, down payment, and location. While our estimates are within range of what a lender will ultimately offer you, the best way to find out is to get a quote from one of our top partners and get pre-qualified.

How do I reduce my monthly payment?

Buying a less expensive home will mean lower monthly payments. Putting more money down upfront also reduces the amount of money you need to borrow. Finally, longer loan terms will reduce your monthly payment (though you will ultimately pay more interest over 30 years than 15). A better rate also means a lower monthly payment, so if you're not in a rush, do what you can to increase your credit score.
