Principal and Interest Payments

Learn how a loan payment applies each month

‍

As we head toward Christmas, many families are spending money and putting a fair amount of those purchases on credit cards. Whether or not a person pays off their credit card debt immediately or over time is a matter of personal choice, but it does remind us of interesting mortgage questions that Orion's brokers often hear from clients: “Why are mortgage payments mostly interest?” and “Can I pay off my mortgage early over time?”

‍

The way mortgages are structured in the United States, for Orion and other lenders, is that each monthly payment is a fixed amount, assuming it's a fully amortizing fixed-rate mortgage, which most tend to be. This setup keeps the total monthly mortgage payment more affordable and predictable as the principal and interest payments are spread evenly over a long loan term, such as 30 years. This means that each monthly mortgage payment includes both principal and interest, ensuring that the loan's principal balance is gradually reduced over time.

‍

Principal and Interest Within Fixed Payments

‍

However, even though the monthly payment is fixed, the composition of principal and interest within that payment will change monthly until the loan term ends. Each month, borrowers are required to make the same principal and interest payment to the lender to satisfy the entire balance over 30 years. While the total monthly payment remains constant, the allocation between principal and interest does not. Initially, the first mortgage payment consists of "mostly interest." As the months progress, the portion of the payment going toward the principal increases while the interest portion decreases.

Example of Principal and Interest on a Mortgage Loan

‍

Let's consider an example to illustrate how principal and interest work on a mortgage loan. Suppose you take out a mortgage loan of $300,000 with a fixed interest rate of 4% over a 30-year term.

In this scenario, your monthly mortgage payment would be approximately $1,432.25. This payment is calculated using a loan calculator that factors in the principal amount, interest rate, and loan term.

• In the early years: The majority of your monthly payment goes toward interest. For instance, in the first month, about $1,000 of your payment would go toward interest, while only $432.25 would reduce the principal balance. This is because the interest is calculated on the outstanding balance of the loan, which is initially high.
• As time progresses: The portion of the payment allocated to the principal increases as the outstanding balance decreases. By the midpoint of the loan term, the principal repayment starts to surpass the interest payment.
• Towards the end of the loan term: The payments are primarily applied to the principal, with very little going toward interest. This is because the loan balance has been significantly reduced, resulting in less interest being charged.

This example highlights how a fixed-rate mortgage amortizes over time, with the principal and interest payments fluctuating based on the outstanding balance. Understanding this can help borrowers make informed decisions, such as whether to make extra payments to pay down the principal faster and potentially save on total interest costs.

Key Takeaways

• To calculate the principal and interest on a simple interest loan, multiply the principal by the interest rate and multiply the result by the loan term.
• Divide the principal by the months in the loan term to get your monthly principal payment on a simple interest loan.
• A loan calculator is helpful when calculating amortized loans to determine the amortized interest payments, which gradually decrease over the course of the loan.
• With fixed-rate loans, your monthly payment will be consistent for simple or amortized interest-based loans.

Principal and Interest Payments Lowers Principal Balance?

‍

Why is this? Well, brokers should tell clients to remember that the first month's principal and interest payment lowered the outstanding principal balance. As a result, the interest due on the second monthly payment dropped, and the principal increased, because as noted earlier, the principal and interest payment amount stays constant. Over time, this trend continues. The principal portion of the monthly mortgage payment increases while the interest portion drops. It's pretty minimal in the beginning because little principal is paid each month with such a large balance demanding so much interest each month. This is the “front loaded” argument your clients hear about: how interest makes up the lion's share of early principal and interest payments. It's not a gimmick, just the way math works.

Understanding this concept is essential for borrowers aiming to optimize their personal finance strategies. As the loan progresses, the shift from interest-heavy to principal-heavy payments becomes more pronounced. This gradual transition is a result of the amortization process, where the principal balance decreases, leading to less interest being calculated on the remaining balance. Consequently, more of each monthly payment is allocated toward reducing the principal.

Help Your Clients Make the Right Decision

‍

Moreover, this understanding can guide borrowers in making decisions about additional principal and interest payments. By making extra payments toward the principal, borrowers can accelerate the reduction of their loan balance, thereby decreasing the total interest paid over the life of the loan. This strategy not only saves money but also helps in shortening the loan term, allowing borrowers to achieve financial freedom sooner.

For those considering refinancing, this knowledge is invaluable. Refinancing can be an effective way to secure a lower interest rate, further reducing the interest portion of monthly payments and enhancing the impact of each principal payment. However, it's crucial to weigh the costs of refinancing against the potential savings to ensure it aligns with long-term financial goals.

Ultimately, a thorough understanding of how principal and interest payments work empowers borrowers to make informed decisions, optimize their mortgage strategy, and potentially achieve homeownership more efficiently.

‍

Making Extra Mortgage Payments

‍

Understanding this dynamic is crucial for borrowers who are considering making extra payments to reduce their loan balance more quickly. By paying more than the required monthly payment, borrowers can directly reduce their principal balance, which in turn reduces the interest calculated on future payments. This can lead to significant savings over the life of the loan. Additionally, some borrowers opt for biweekly payments, which can also accelerate the reduction of the principal balance and decrease the total interest paid on their principal and interest payments.

‍

Extra Payments Applied to Principal and Interest

‍

It's important for borrowers to communicate with their mortgage lender or servicer to ensure that any extra payments are applied directly to the principal. This proactive approach can help borrowers manage their personal finance more effectively and potentially shorten their loan term. Many borrowers find that by understanding how principal and interest payments work, they can make informed decisions about their mortgage strategy, ultimately leading to lower total interest costs and a faster path to homeownership.

But in month 153, or nearly 13 years into a 30-year mortgage, the principal portion of the mortgage payment finally surpasses the interest portion. In other words, the lender or servicer still very much owns your client's home, even though they think they're the “king of your castle.

However, this is where the principal really starts to get paid down, as interest finally takes a back seat. During the final year of the loan term, each monthly payment is more than 96% principal, with very little interest due because the outstanding balance is so low.

‍

The Realty of Mortgage Terms

‍

In reality, many homeowners don't hold their mortgages for the full loan term. Most borrowers typically maintain their loans for only a fraction of the term, such as seven or eight years, before refinancing, prepaying the mortgage, or selling the home. During this period, many borrowers choose to make additional payments throughout the year, often due to receiving a bonus, which directly reduces the outstanding principal balance. This behavior is precisely why principal and interest payments tend to be predominantly interest in the early years. Since many borrowers never reach the point where the principal portion of their monthly payments surpasses the interest portion, the principal and interest payments remain skewed towards interest.

‍

Interested in Refinancing?

‍

For those considering refinancing, it's important to evaluate whether the new terms will actually save money over the long run, taking into account the costs associated with refinancing. Prepaying the mortgage can be a strategic move to reduce the principal balance faster, thereby decreasing the total interest paid over the life of the loan. Selling the home and paying off the mortgage early can also free up equity that can be used for other investments or purchasing a new property.

Additionally, understanding the amortization schedule can empower homeowners to make informed decisions about their mortgage's principal and interest. By examining this schedule, borrowers can see exactly how much of each monthly payment is going toward interest versus principal, helping them strategize about when and how much extra to pay to achieve their financial goals. If your clients have questions about how principal and interest payments amortize and pay off over time, it is a great way for brokers to add value!
