Rates Affect My Loan What Is an Interest Rate?

Definition of Interest Rate
An interest rate is the cost of borrowing money, expressed as a percentage of the principal (original loan amount). It is what the lender charges you for using their funds.
Types of Interest Rates
- Fixed Interest Rate: Remains constant throughout the loan term.
- Variable Interest Rate: Can fluctuate based on market conditions or benchmarks like the RBI repo rate.
Factors That Influence Interest Rates
1. Central Bank Policy
Central banks (e.g., Reserve Bank of India) adjust interest rates to control inflation and stimulate or slow down economic activity.
2. Inflation
Lenders raise interest rates during inflationary periods to maintain the real value of money.
3. Loan Term
Shorter-term loans usually come with lower interest rates than long-term loans due to reduced risk exposure.
4. Credit Score
A higher credit score often translates into lower interest rates because you’re seen as a low-risk borrower.
5. Loan Type and Purpose
Mortgages, student loans, and personal loans all have different typical rates. Secured loans usually have lower rates than unsecured loans.
How Interest Rates Affect Loan Repayment
Monthly Payments (EMIs)
Higher interest rates result in higher Equated Monthly Installments (EMIs), increasing your monthly financial burden.
Total Interest Paid
Over the life of the loan, even a small increase in interest rate can mean thousands more in interest payments.
Loan Affordability
A higher interest rate may reduce the amount of loan you’re eligible for, especially if you have a limited income.

- Private education loans usually come with higher interest rates.
Fixed vs Variable Interest Rates

Fixed Rate Loans
- EMI remains constant.
- Ideal when interest rates are expected to rise.
Variable Rate Loans
- EMI may increase or decrease based on benchmarks.
- Beneficial in a falling rate environment.
Interest Rate and Credit Score Relationship
Credit Score Range | Likelihood of Approval | Expected Interest Rate |
---|---|---|
750–900 | Very High | Low |
700–749 | High | Moderate |
650–699 | Medium | Higher |
Below 650 | Low | Very High |
Improving your credit score can help you secure a lower interest rate, saving you significant money.
Economic Impact on Interest Rates
Government Policies
Changes in taxation, monetary policy, and deficit financing can push interest rates up or down.
Market Demand and Supply
If demand for loans increases, banks may raise interest rates to manage risk and liquidity.
How to Minimize Interest Costs
1. Shop Around
Compare interest rates from different lenders and check offers from online aggregators.
2. Opt for Shorter Tenure
A shorter loan term typically attracts lower interest, reducing the total interest paid.
3. Prepayment and Part Payment
If your loan allows it, making lump sum payments can reduce principal and lower total interest.
4. Choose the Right Loan Product
Secured loans generally offer better rates than unsecured ones.
5. Maintain a Good Credit Profile
Pay EMIs and credit card bills on time to maintain a healthy credit score.
