Getting a loan seems like an easy solution when you are short of money. But it is a serious commitment that can affect your finances today and in the future. Understanding the long-term impact of borrowing is important when you decide to go for any kind of loan, whether it is a line of credit or something as significant as a mortgage.

What is a loan?

A loan is a financial instrument that provides capital to the borrower. It means that a lender, such as a bank or financial institution, gives you an amount of credit with an agreement that it will be paid at a later stage. It is usually repaid in installments.

The repayment, however, also includes some interest in addition to the principal amount. Mortgages, auto loans, personal loans, lines of credit, and business loans are all examples of various types of loans.

Components of a Loan

So now that we have an idea of what a loan is, let us see some essential parts that define how much you’ll borrow, pay back, and owe over time.

  • Principal amount: This is the original amount that you have borrowed. So, if you borrowed $20,000 for a car, the $20,000 will be called the principal amount.
  • Interest: The interest is the cost of borrowing. This is the amount that you have to pay in addition to the principal amount. Interest depends on various factors and is expressed as an annual percentage rate (APR).
  • Term or Loan Duration: The period that you have to repay the loan is called the loan term or loan duration. Loan term is usually expressed in months or years.
  • Monthly Payments or Installments: The repayment of the loan is spread over multiple periods, usually expressed in months. It includes the principal and the interest. Each month you pay off a portion of the loaned amount plus interest till all debt is paid off.
  • Additional fees: Besides the principal and the interest, loan disbursements also include other fees. These could be administrative charges, penalties for late payment, origination fees, etc.
  • Collateral: Collateral is something that a borrower pledges to secure a loan. If a borrower fails to make repayments, the lender can recover the loaned amount by selling the collateral.

Types of Loans

Loans are of different types, and their costs depend on the nature of the loan and its purpose. For more clarity, we will split them into two categories: secured and unsecured, and revolving vs. term loans.

Secured vs Unsecured Loans

Collateral is used to protect the lender from losses. Such a loan is called a secured loan because the amount is protected in case of default by the borrower. The collateral is usually the asset for which the loan is taken out, such as the house for a mortgage. Secured loans are usually long-term and have a lower interest rate.

An unsecured loan is not backed by any valuable asset. Because such loans have a higher risk, they are offered at a higher interest rate. These loans are not always easy to obtain. A credit card is an example of such a loan. Usually, a credit card application will not be entertained from someone who has a poor credit history, or if extended, it will be offered at a very high interest rate.

Revolving vs Term Loans

Loans are also differentiated on the basis of how credit is made available to the borrower. If the credit access is continual, it is referred to as a revolving credit facility. This flexible arrangement allows businesses to borrow, spend, and repay, and then borrow again in an agreed-upon period. However, the downside is that it has a varying interest rate that fluctuates with market conditions, often higher than other types of loans.

Extending such a facility requires full scrutiny of the health of the business or an individual’s credit history. Banks examine income statements, cash flow statements, and balance sheets for businesses. For individual borrowers, their credit history, income, and debt-to-income ratio are assessed.

The opposite of a flexible line of credit facility is a fixed-term loan. These loans are a lump sum upfront payment with certain terms and conditions. Small businesses often use term loans for needs like purchasing machinery, building new premises, or buying fixed assets. Term loans can have a fixed or variable interest rate and are usually repaid through monthly or quarterly payments.

Understanding Interest

One term always present in any discussion of any type of loan is the interest rate. Now, let us understand what is meant by an interest rate and why it is critical to consider when borrowing money.

The concept of interest is perhaps best explained by John Keynes. According to him, the rate of interest is the reward for parting with liquidity for a specified period of time.

Simply put, interest is the amount given to the lender as a reward for taking the risk of lending money and sacrificing the chance of using it. Higher-risk loans usually carry a higher interest rate.

Types of Interest Rates

Fixed Interest Rate

The interest rate remains the same throughout the life of the loan. It has predictable monthly payments.

Example: A $20,000 car loan at a fixed 6% annual rate means your payments won’t change for the loan term.

Variable (or Adjustable) Interest Rate

The interest rate can change over time, often tied to a benchmark like the prime rate. Payments can rise or fall as the benchmark changes.

Example: A HELOC with a variable rate of 5% could increase to 6% if the benchmark rises, increasing your payments.

Simple Interest

Interest is calculated only on the principal amount, not on accumulated interest.

Example: Borrow $10,000 at 5% simple interest for one year. Interest = $500. Total repayment = $10,500.

Compound Interest

Interest is calculated on both the principal and any previously accumulated interest. It increases the total loan cost.

Example: Borrow $10,000 at 5% annual compound interest. After one year, Total = $10,500. If compounded monthly, the total interest would be slightly higher.
