## Introduction

In finance, the principal is the amount of money that is borrowed or invested, not including any interest or other fees. In loans and mortgages, the principal is the initial amount of money that is borrowed, before any interest or other fees are added. The term “principal” can also refer to the primary amount of money invested in a security, before any income or capital gains are earned on that investment.

## What is Principal Amount?

The principal amount is the total amount of money that you borrowed from the lender. This does not include any interest or fees that may have been charged. The principal amount is important because it is used to calculate the amount of interest that you will owe on your loan.

### The Meaning of Principal

When you take out a loan, the principal is the sum of money you borrow. With each loan payment, part of your payment goes to reducing the principal while the rest covers the interest owed. The amount of each payment that pays down the principal is called the “amortized payment.” The table below shows how your amortized payments change over time as you pay down your loan.

Loan amount: \$100,000
Annual interest rate: 5%
Term of loan: 30 years

Amortization schedule for a \$100,000 loan with a 5% annual interest rate and 30-year term

Year1: \$536.82 paid toward principal; \$477.61 in interest paid; outstanding balance: \$99,463.18
Year2: \$552.27 paid toward principal; \$462.16 in interest paid; outstanding balance: \$98,910.91
Year3: \$567.90 paid toward principal; \$446.53 in interest paid; outstanding balance: \$98,343.00

### How Principal is Used in Loans

The principal is the original sum of money borrowed in a loan. Interest is charged on the outstanding principal amount, which is the principal plus any accumulated interest. When a borrower makes a loan payment, a portion of the payment goes toward reducing the outstanding principal balance, and the rest covers the interest charged on the loan.

## How the Principal is Calculated

When you take out a loan, the principal is the sum of money that you borrow. This amount doesn’t include the interest, which is the fee you’re charged for borrowing the money. The interest is calculated as a percentage of the principal.

### The Formula for Calculating Principal

The principal of a loan is the amount of money that you borrow from a lender. The interest rate is the percentage of the loan that you pay to the lender as interest. The formula for calculating principal is simple:

P = L – I

where P is principal, L is the total loan amount, and I is the interest paid on the loan.

### How to Use the Principal Formula

To calculate the principal amount of a loan, you’ll need to know the original loan amount, the interest rate, and the term of the loan. You can use this formula:

P = L[1 – (1 + i)^-n]] / i

where:

P = Principal Amount
L = Loan Amount
i = Interest Rate (as a decimal)
n = Loan Term (in months)

## The Benefits of Knowing Your Principal

Your principal is the amount of money you borrow from a lender. Your interest rate is based on your creditworthiness and the prime rate. Principal is important because it’s the amount of money you’ll need to repay, not including interest. Keep reading to learn more about your principal and how it can affect your loan.

### You Can Make Informed Decisions

If you know how much your loan payments are going to be, you can make informed decisions about your monthly budget. When you know how much you have to work with each month, it is easier to make choices that allow you to live within your means. This can help you avoid debt problems in the future.

A loan’s principal is the original sum of money borrowed. For example, if you take out a loan for \$100,000, the principal is \$100,000. Each loan payment you make applies first to any interest owed, and the remainder of the payment (if any) goes toward reducing the principal. The lower your principal balance becomes, the less interest accrues on your loan over time.

### You Can Negotiate a Lower Interest Rate

If you have a good relationship with your banker or loan officer, you may be able to negotiate a lower interest rate on your loan. This is especially true if you have been a loyal customer of the bank for many years. It’s always worth asking if you can get a lower rate.

## Conclusion

The principal amount of a loan is the original amount that you borrowed, before any interest or other fees are added. If you’re still paying off your loan, the principal is the remaining balance that you owe. Once you’ve paid off your loan in full, the principal is the total amount that you originally borrowed.
