When it comes to loans, you may have heard of the term “principal payment.”

Understanding principal payments is helpful for managing personal finances and ensuring that you pay off your debt in a timely manner. Keep reading to explore what principal payment is, its importance, and how it impacts loan repayment.

Key takeaways

  • When you make a loan payment, you’re paying toward two parts: the principal and the interest.
  • Principal payment is the part of a loan payment that reduces the original loan amount.
  • Interest payment is the part of a loan payment that goes toward paying interest charges.
  • A repayment plan determines how payments toward principal and interest are distributed, and it varies between products and lenders.

What is a loan principal?

The principal refers to the amount of money borrowed, excluding interest. When you take out a loan, such as a mortgage, car loan, or personal loan, the principal is the original sum you agree to repay over a specified period. Even as you pay it down, that borrowed amount is still called the principal.

Say your car cost $10,000. You put $1,000 down and finance $9,000. The principal amount is $9,000. As you pay it back, your principal will go down.

Understanding principal payments

At its core, the principal payment refers to the portion of a loan payment that goes toward reducing the original amount borrowed. In other words, it’s the repayment of the initial sum borrowed, excluding interest.

What components make up a loan payment?

A loan payment is generally composed of two main parts: The principal payment and the interest payment.

Principal payment

The principal payment is the portion of the loan payment that reduces the outstanding balance. For example, if you borrow $1,000 and pay $100 toward the principal, the remaining balance would be $900.

Interest payment

The interest payment is the portion of the loan payment that goes toward the interest charged by the lender. Interest is the cost of borrowing and is usually expressed as a rate of the principal. For example, you may have a 10% interest rate. How much you end up paying in interest depends on the length of the repayment period.

Fixed principal payments vs. fixed total payments

There are different ways to structure loan repayments. Said another way, there are different calculations used for how a loan is repaid. For example, two such structures have fixed principal payments or fixed total payments (also called even principal payments or even total payments).

Fixed principal payments

When the size of a loan payment decreases over time, it’s a fixed principal payment plan. The principal amount paid each period remains constant, but the total payment amount decreases because the interest is calculated on the decreasing principal balance.

Consider a $10,000 loan with a term of 5 years and an annual interest rate of 5%:

Year Principal Payment Interest Payment Total Payment
Year 1 $2,000 $500 $2,500
Year 2 $2,000 $400 $2,400
Year 3 $2,000 $300 $2,300
Year 4 $2,000 $200 $2,200
Year 5 $2,000 $100 $2,100

Fixed total payments

When the size of the loan payment remains the same over the whole repayment schedule, it’s a fixed total payment. The total amount paid each period remains the same but the portion going toward the principal and interest changes. Early payments mostly cover interest, while later payments cover more principal.

Consider a $10,000 loan with a term of 5 years and an annual interest rate of 5%:

Year Principal Payment Interest Payment Total Payment
Year 1 $1,528 $500 $2,028
Year 2 $1,605 $432 $2,028
Year 3 $1,688 $340 $2,028
Year 4 $1,776 $252 $2,028
Year 5 $1,872 $156 $2,028

These basic examples are for understanding only. Repayment calculations can consider other factors, like whether the interest is compounding.
