Principal and interest are the two components that make up a mortgage. The principal is the amount borrowed; interest is the payment for the debt. The portion of the monthly payment which goes to the principal varies depending on the loan. Find out more about what all a mortgage payment consists of below.

‍

What Is the Principal of a Mortgage Payment?

The principal is the amount borrowed when you took out the home loan. The formula for calculating the total is the home's selling price minus the down payment.

‍

The principal is the deciding factor in how much one can afford. For example, if you qualify for a $300,000 mortgage, that is the principal. As soon as you take out the mortgage, it begins accumulating interest at an agreed rate. 

‍

What Is the Interest on a Mortgage Payment?

When taking out a loan, the interest is the amount the lender charges for using their service. Most creditors will calculate mortgage interest rates through APR (annual percentage rate). APR is the loan's interest, including annual fees.  For instance, the $300,000 mortgage, at an APR of 5%, would be $15,000 annually. 

‍

How Does Interest Affect the Total Paid Over the Life of the Loan?

Over time, your interest payment will go down while your principal will go up. Let's say the $300,000 home loan has a fixed-rate, 30-year mortgage at 3 percent. The payments will be $1,264.81. The first payment, $749.81, will cover the interest, while $515 goes toward the principal. 

‍

However, by year 20 of the mortgage, the principal will be higher than the interest. While the payments stay the same (on a fixed-rate mortgage), the money going toward the principal increases across the life of the loan.

‍

How Does the Principal Affect the Interest?

Although several factors (credit score, work history, etc.) influence it, a general rule is that the higher the principal, the higher the interest. That is because lenders take on higher risk when they lend more money and want ample compensation. 

‍

The more secure a loan, the less interest. So higher down payments, good credit scores, and solid work history will lower interest rates when applying.

‍

Understanding Amortization

Why does the payment stay the same if the interest rate is paid on a declining balance? It is due to a process called "Amortization."

‍

How Does Amortization Work?

Lenders use amortization to distribute mortgages across the loan life in equal payments. It works by increasing the principal (payment on the actual amount owed) while decreasing the interest (payment on the amount the lender charges).

‍

Adjustable vs. Fixed-Rate Mortgages

The mortgage type affects the way amortization works on a loan. With a fixed-rate mortgage, amortization happens as outlined above. However, with an Adjustable-Rate Mortgage (ARM), the payment changes based on interest rates. Although you still pay more toward the principal throughout the loan, the monthly payment will fluctuate.

Refinancing to Lower Principal Payments

Refinancing a home can lower principal payments and the interest rate. Alas, there are also many fees, such as closing costs. Refinancing is beneficial if you save more across the rest of the loan term than the fees and closing costs.

Strategies for Paying Off Principal Faster

Several effective strategies can pay off the principal quicker. These include rounding up, making bi-weekly payments, and making extra payments. All of these methods involve paying more than is required.

‍

Specify that the payment goes to the principal. Although standard, check with your lender to ensure the money goes where you requested.

‍

• Rounding up: The principal will be paid faster by rounding off the payment. The benefit of this method is that you still pay once a month.
• Bi-weekly payments: Pay half the monthly amount every two weeks to follow this strategy. This system will result in you making 13 payments per year. The benefit of bi-weekly payments is that they maintain regularity, but you are more active in lowering the principal.
• Making extra payments: As long as the required monthly payment is paid, you can make additional payments of any amount at any time.

‍

Who Determines How Big of a Payment Goes to the Principal?

The lender decides how much of the payment goes to the principal based on your amortization schedule. The amount depends on the loan size, interest rate, and terms.
