How much youll pay will depend on the type of loan you choose Part of the Series Using a Mortgage Calculator
When you buy a home with a mortgage, you dont just pay back the amount you borrowed, known as the principal. You also pay mortgage interest on the loan amount you havent yet repaid. This is the cost of borrowing money. How much you will pay in mortgage interest varies depending on factors like the type, size, and duration of your loan, as well as the size of your down payment.
Typically, a bank or mortgage lender will finance 80% or more of the price of the home, and you agree to pay it back—with interest—over a specific period. As you compare lenders, mortgage rates, and loan options, its helpful to understand how mortgages work and which kind may be best for you.
Buying a home is an exciting milestone in life. But it also involves navigating the complex world of mortgages and interest rates. As a homebuyer, it’s important to understand how interest on home loans works so you can make informed decisions. This guide will explain in simple terms the basics of mortgage interest and how it impacts your home loan.
What is Interest on a Home Loan?
When you take out a mortgage to buy a home, you are borrowing money from a lender. The lender charges you interest on top of the amount you borrowed (known as the loan principal). This interest is the cost you pay for borrowing the money.
The interest rate is expressed as a percentage of the loan amount. For example, if you take out a $200,000 mortgage with a 5% interest rate, you will pay $10,000 in interest charges for the first year of the loan (5% of $200,000)
As you make monthly payments part of each payment goes towards the loan principal and part goes towards paying the interest owed. Over the life of the loan you will end up paying significantly more than the original amount you borrowed due to all the accumulated interest charges.
How is Mortgage Interest Calculated?
There are a few key factors that determine how much interest you will pay on your home loan
-
Loan amount – The larger your loan, the more interest you will pay overall.
-
Interest rate – The higher the rate, the more interest you will be charged each month and over the life of the loan. Rates are generally lower for borrowers with good credit and higher down payments.
-
Loan term – Mortgages are commonly offered in 15 or 30 year terms. The longer the term, the more interest you will pay over time.
-
Amortization – This is the schedule of how much of your payment is applied to interest vs principal each month. In the early years, more goes to interest. In later years, more goes to principal.
Your lender will use a formula called amortization to calculate your monthly payment amount. This factors in the loan amount, interest rate, and loan term to determine how much of each payment covers interest costs.
As an example, on a $200,000 loan at 5% interest over 30 years, your monthly payment would be around $1,073. In the first month, $833 would go towards interest and $240 would reduce the loan principal. But in the final month, only $40 would go to interest while $1,033 would pay down the principal.
Why Do Mortgage Rates Vary?
Mortgage interest rates fluctuate daily based on the broader economy and policies set by the Federal Reserve. But when you apply for a loan, the rate you are offered will depend mainly on your personal financial situation.
Lenders assess your credit score, income, assets, debts, and other factors to determine your risk level as a borrower. The lower the risk you pose, the lower the rate since the lender feels more confident you will repay the loan. Those with excellent credit and 20% down payments tend to get the very best rates.
Rates also vary by loan type. Fixed-rate mortgages lock in an interest rate for the full term while adjustable-rate mortgages have rates that change periodically. Jumbo loans for higher home values tend to have slightly higher rates as well.
Should I Choose a Fixed or Adjustable Rate Mortgage?
This is one of the big decisions borrowers face. Here is a quick comparison of the two options:
Fixed-rate mortgage
- Interest rate stays the same for full term
- Monthly payments do not change
- Provides predictable budgeting
- Typically higher initial rates than adjustable loans
- Best if staying in home long-term
Adjustable-rate mortgage (ARM)
- Initial interest rate is low but will vary over time
- Monthly payments change with rate fluctuations
- Unpredictable long-term costs
- Risk of much higher payments if rates rise
- May make sense if staying only short-term
Fixed-rate mortgages provide stability while ARM rates can start low but become risky. Consider your time horizon in the home and risk tolerance to decide which works better.
How Much Interest Will I Pay Over the Life of My Loan?
The total amount of interest paid over the full loan term depends on the factors we’ve covered like the rate, loan amount, and term length. But as a general guideline:
-
On a $200,000 fixed-rate loan at 4% interest, you would pay about $215,000 in total interest payments over 30 years.
-
On a $300,000 loan at 6% interest over 15 years, you would pay approximately $160,000 in interest.
An online mortgage calculator can help you estimate total interest costs based on your specific loan details. Be sure to look at the total interest paid over the full term, not just monthly or annual interest.
Tips for Minimizing Interest Costs
Here are some tips to get the lowest interest rate possible and reduce the total interest paid:
-
Improve your credit – Work on increasing your credit score to get better rate offers
-
Shop lenders – Compare interest rates from multiple lenders
-
Make a larger down payment – Putting 20% down or more if possible to get the best rates
-
Lower your debt – Pay down other debts so you qualify for a lower mortgage rate
-
Pick shorter term – Opt for a 15-year mortgage over 30 years to pay interest for less time
-
Make extra payments – Paying additional principal voluntarily reduces interest faster
-
Refinance when rates drop – Consider refinancing if rates fall at least 0.5-1% below your current mortgage rate
Understanding how interest on home loans works is key to making the best borrowing decision and keeping costs low when you buy a property. With the right loan choice and smart financial moves, you can minimize the impact of interest and keep your dream home affordable.

What Interest Rate Will I Get When I Take out a Mortgage?
The interest rate you get on your mortgage depends on a variety of factors. The economic climate and interest rates set by the Federal Reserve impact mortgage rates, as do other things.
From there, lenders will calculate your interest rate based on your financial situation, including your credit score, any other debts you have, and your likelihood of defaulting on a loan. The less risky a lender thinks it is to lend your money, the lower your interest rate will be.
Jumbo Mortgage Loans
A jumbo mortgage is usually for amounts over the conforming loan limit. In 2024, this limit is $766,550 for most parts of the U.S., a $40,350 increase over the 2023 limit of $726,200. The 2024 maximum conforming loan limit is $1,149,825 for high-cost areas. This is 150 percent of $766,550 and an increase over the 2023 maximum limit of $1,089,300.
Jumbo loans can be either fixed or adjustable. Their interest rates tend to be slightly higher than those on smaller loans of the same type.
Interest-only jumbo loans are also available, though usually only for the very wealthy. They are structured similarly to an ARM, and the interest-only period lasts as long as 10 years. After that, the rate adjusts annually, and payments go toward paying off the principal. Payments can go up significantly at that point.
Even with a fixed-rate mortgage, your monthly payment can change if it also includes taxes or insurance.
