Interest rate is one of those financial terms that directly affects everyone—whether you’re taking a home loan, keeping money in a fixed deposit, or even using a credit card. Yet, many people in India don’t fully understand what an interest rate actually is and how it works behind the scenes.
In this blog, we’ll break down what an interest rate means, how interest rates work in India, and why RBI decisions matter to you, using simple, real-life explanations.
What Is an Interest Rate?
An interest rate is the cost of borrowing money or the return earned on savings, expressed as a percentage.
If you borrow money (home loan, personal loan), interest is the extra amount you pay to the bank.
If you save or invest money (FD, savings account), interest is the income you earn.
Example: If you borrow ₹10 lakh at an interest rate of 8% per year, you pay ₹80,000 annually as interest (excluding principal repayment).
How Interest Rates Work in India
In India, interest rates don’t change randomly. They follow a structured system influenced by the Reserve Bank of India (RBI), banks, inflation, and market conditions.
1. Role of the Reserve Bank of India (RBI)
The RBI is the central authority that controls monetary policy in India. It does this mainly through:
Repo Rate – the rate at which RBI lends money to banks
Reverse Repo Rate – the rate at which banks park money with RBI
When RBI changes the repo rate, banks adjust their lending and deposit interest rates accordingly.
Types of Interest Rates in India
1. Fixed Interest Rate
Remains the same throughout the loan tenure
EMI stays predictable
Usually slightly higher than floating rates
2. Floating Interest Rate
Changes with RBI rate movements
EMI may increase or decrease over time
More common for home loans in India
How Interest Rates Affect Common People
Home Loan Borrowers
Higher interest rate = higher EMI
Even a 1% increase can cost lakhs over long tenure
Savings & Fixed Deposits
Higher rates benefit FD investors
Lower rates reduce savings income
Businesses & Economy
High interest rates slow borrowing and spending
Low interest rates encourage growth but may increase inflation
Why Interest Rates Change Frequently
Interest rates in India change mainly due to:
Inflation levels
Economic growth
Global interest rate trends
Rupee stability
Liquidity in banking system
RBI balances growth and inflation—keeping rates too low or too high can harm the economy.
Interest Rate vs EMI: What’s the Real Connection?
EMI depends on:
Loan amount
Interest rate
Loan tenure
Even a small interest rate change can significantly alter:
Monthly EMI
Total interest paid
Loan affordability
That’s why understanding interest rates is crucial before applying for any loan.
