What Is Interest on a Loan?

Borrowing money is not free. When someone takes a loan, they usually pay an extra amount in addition to the money they borrowed.
This extra amount is called interest.
To understand this better, it helps to first know
what a loan is
and how borrowing works.
This beginner-friendly guide explains what interest on a loan means, why it exists, and how it works, using very simple words and examples.

What Does Interest Mean in Simple Words?

Interest is the extra money a borrower pays to the lender for using borrowed money.
It is paid on top of the original loan amount, which is called the principal.
Interest is usually charged over time, such as monthly or yearly, until the loan is fully repaid.

In simple terms, interest is the cost of borrowing money.

Why Do Lenders Charge Interest?

Lenders charge interest for several basic reasons.
First, when a lender gives money to someone else, they cannot use that money themselves during that time.
Interest is a way to compensate the lender for waiting.

Second, there is always a risk that the borrower may not repay the loan fully or on time.
Interest helps cover this risk.
Finally, money today is generally more valuable than money received later, which is known as the time value of money.

How Interest on a Loan Works

When a borrower takes a loan, they receive a certain amount of money called the principal.
Interest is then applied to this principal amount over the loan period,
which is part of
how loans work.

The borrower repays the loan by paying back both the original principal and the interest.
This repayment usually happens in parts, such as monthly payments, until the loan ends.

For example, if someone borrows money for a personal need, they return the borrowed amount along with an extra amount as interest for using that money.

Key Terms Related to Loan Interest

Understanding a few basic terms can make loan interest easier to understand.

• Principal: The original amount of money borrowed.
• Interest Rate: The rate used to calculate how much interest is charged.
• Loan Tenure: The total time given to repay the loan, also known as
  loan tenure.
• Total Repayment: The full amount paid back, including principal and interest.

Types of Interest on a Loan

Simple Interest

Simple interest is calculated only on the original loan amount.
The interest amount remains straightforward and does not change based on previous interest.
This type of interest is easier to understand for beginners.

Compound Interest

Compound interest is calculated on both the original loan amount and the interest added over time.
This means interest can grow faster compared to simple interest.
The concept is important, even without knowing any formulas.

Fixed Interest Rate

A fixed interest rate stays the same throughout the loan period.
This means the interest portion does not change, making repayments predictable.

Variable Interest Rate

A variable interest rate can change over time.
It may increase or decrease depending on certain conditions, such as market changes.

Interest on a Loan vs Interest Earned

Loan interest and savings interest are often confused.
When someone takes a loan, they pay interest to the lender.
When someone saves money in a bank or investment, they may earn interest on their savings.

One is a cost, and the other is income.

Is Interest the Same for All Loans?

Interest is not the same for all loans.
Different types of loans can have different interest structures,
depending on the
types of loans.

Factors such as loan duration, loan purpose, and level of risk can influence how interest is applied.

This is why education loans, home loans, and personal loans may all work differently.
