How Do Loans Actually Work?

Imagine you want to buy a ₹1 lakh laptop, but you don't have ₹1 lakh saved. Instead of waiting until you can afford it, you could take a loan from a bank and repay the money over time.

That sounds simple, but borrowing ₹1 lakh does not usually mean paying back exactly ₹1 lakh. The lender charges interest, which is the cost of borrowing the money.

So, what are you actually paying back?

A loan usually has three important parts:

• Principal: the amount you originally borrowed.

• Interest: the additional cost charged for borrowing.

• Repayment period: how long you have to pay the money back.

  
  

Suppose you borrow ₹1,00,000 and, over the repayment period, you end up paying ₹1,12,000 in total. The original ₹1,00,000 is the principal, while the extra ₹12,000 is the interest.

The exact amount of interest depends on factors such as the interest rate, loan amount and repayment period.

What are EMIs?

For many loans, you don't repay everything at once. Instead, you make regular payments called EMIs (Equated Monthly Instalments).

For example, if you take a loan and agree to repay it over 12 months, you would make a payment each month until the loan is fully repaid.

Each EMI generally includes a portion of the amount you borrowed and the interest charged on it.

A longer repayment period can make each monthly payment smaller, but it can also mean paying interest for longer. So a loan with a lower monthly EMI isn't automatically cheaper overall.

Why does the interest rate matter?

Imagine two people each borrow ₹1 lakh for the same period. If one gets a lower interest rate, they will generally pay less interest over the life of the loan.

This is why comparing loans isn't just about asking, “How much will I pay each month?” You also need to look at the total amount you will repay.

What happens if you don't repay?

A loan comes with an agreement to repay on time. Missing payments can lead to late fees, additional interest and damage to your credit history. Repeatedly failing to repay can make it harder or more expensive to borrow money in the future.

So before taking a loan, it's important to think beyond “Can I get the money?” and ask:

“Can I comfortably repay it?”

That question becomes even more important when we look at credit scores, which help lenders decide how trustworthy someone is at repaying borrowed money.
