1. What Is a Fixed Interest Rate?
A fixed interest rate is a rate that remains unchanged for a specified period of the loan, depending on the terms offered by the lender.
Because the rate remains fixed during that period, the borrower has greater predictability when planning monthly loan payments. However, the exact terms of a fixed-rate loan can vary between lenders and products.
2. What Is a Floating Interest Rate?
A floating interest rate can change over time based on the applicable benchmark, lending rate or other terms specified in the loan agreement.
When the applicable rate changes, the borrower may see a change in the EMI, repayment tenure or both, depending on how the loan is structured.
3. Fixed vs Floating: Key Differences
The main difference is how the interest rate behaves over time. A fixed rate provides more stability during the applicable fixed period, while a floating rate can move as market or benchmark-linked rates change.
This means the monthly payment and total borrowing cost may be easier to estimate with a fixed rate during the fixed period. With a floating rate, future payments may change as the applicable interest rate changes.
4. How Interest Rate Changes Affect a Loan
Even a relatively small change in the interest rate can affect the cost of a loan, particularly when the outstanding principal is large or the remaining tenure is long.
For a floating-rate loan, an increase in the applicable rate can increase the repayment burden or extend the repayment period. A decrease in the rate may have the opposite effect, depending on the loan terms.
5. What to Check Before Choosing a Rate
Before choosing between fixed and floating rates, review the loan agreement carefully. Check how long a fixed rate applies, how a floating rate is determined and what happens when the applicable rate changes.
You should also consider processing fees, conversion or switching conditions, prepayment terms and other applicable charges. Looking at the complete loan structure can provide a better comparison than focusing only on the initial interest rate.
6. Compare Loan Options
A loan comparison calculator can help you compare different interest rates, loan amounts and repayment tenures. You can use different assumptions to understand how changes in the rate may affect EMI and total interest.
Comparing multiple scenarios can make it easier to understand the potential cost of each loan rather than looking at the advertised interest rate alone.
Example: Fixed vs Floating Rate
Suppose two loans have the same principal amount and repayment tenure. One loan uses a fixed interest rate while the other uses a floating rate.
The fixed-rate loan may provide more predictable payments during its fixed period. The floating-rate loan may have a different repayment cost later if the applicable interest rate changes.
Comparing the EMI, interest rate and total repayment under different rate scenarios can help you understand how each loan could behave over time.
The Bigger Picture
The choice between fixed and floating interest rates involves more than comparing the initial rate. Understanding rate changes, repayment flexibility, loan tenure and the overall cost of borrowing can help you evaluate different loan structures more carefully.
Things to Consider
- Check how long a fixed interest rate applies.
- Understand how a floating interest rate is determined.
- Consider how a rate change could affect your EMI or loan tenure.
- Compare total interest and total repayment, not only the initial rate.
- Review fees, switching conditions and prepayment terms before choosing a loan.
Compare Your Loan Options
Compare EMI, interest rate, total interest and total repayment to understand the overall cost of different loan options.
Frequently Asked Questions
What is the main difference between fixed and floating interest rates?
A fixed interest rate generally remains unchanged for the applicable fixed period, while a floating interest rate can change based on the applicable benchmark or lending rate.
Can a floating interest rate increase?
Yes. A floating rate can increase when the applicable benchmark or lending rate increases, subject to the terms of the loan.
Can a floating interest rate decrease?
Yes. A floating rate can decrease when the applicable benchmark or lending rate decreases, subject to the terms of the loan.
Does a fixed interest rate always remain fixed for the entire loan?
Not necessarily. The applicable fixed period and any later rate changes depend on the terms of the specific loan agreement.
What should I compare before choosing a loan?
Compare the interest rate, EMI, loan tenure, total interest, total repayment, fees and other terms that may affect the overall borrowing cost.
