Fixed vs Floating Interest Rates: Which is Better?

When applying for loans, one of the most important decisions borrowers face is choosing between a fixed interest rate and a floating interest rate. The decision affects monthly repayments, overall borrowing cost and financial planning.

Understanding the difference between fixed and floating interest rates can help borrowers select the most suitable loan structure based on their financial goals.

What are fixed interest rate loans?

Fixed interest rate loans are loans in which the interest rates remain constant throughout the loan tenure or for a predetermined period. This means that your monthly instalments remain unchanged regardless of fluctuations in market interest rates.

Fixed interest rate loans provide certainty and predictability. Borrowers know exactly how much they need to pay every month, making budgeting easier.

Example:

If a borrower takes a loan at a fixed rate of 8% for ten years, the interest rate will remain the same throughout the agreed period, even if the repo rate or bank rate fluctuates.

What are floating interest rate loans?

Floating interest rate loans are loans in which the interest rate changes according to benchmark rates set by the financial institutions. As these benchmark rates increase or decrease, the loan interest rates also change.

Floating interest loans are typically linked to external benchmarks such as the RBI repo rate. Therefore, either the monthly instalments or the loan tenure may vary during the repayment period.

A floating-rate loan can help borrowers benefit when interest rates decline. However, rising interest rates can increase borrowing costs.

How are fixed and floating rates determined?

Fixed interest rates are determined by lenders based on factors such as current market interest rates, funding requirements, competition, credit risk, and the loan or investment tenure.

For example, banks determine fixed deposit rates according to their liquidity requirements and prevailing market conditions, while bond issuers set coupon rates based on borrowing costs and investor demand. Once the borrower or the investor accepts the offer, the fixed rate remains unchanged for the agreed period.

Floating interest rates work differently. They are linked to an external benchmark, such as the RBI repo rate, Treasury bill yields, or other market-based rates, along with an additional spread charged by the lender.

These rates are reviewed and reset at regular intervals, meaning your borrowing cost can increase or decrease over time depending on changes in the benchmark rate.

The RBI promotes transparency in floating-rate lending. Banks are required to clearly disclose the benchmark used for determining interest rates in applicable loan products. This ensures that borrowers understand how and why their loan rates may change during the repayment period.

Fixed vs Floating Interest Rates: Direct Comparison

The debate around fixed vs floating interest rate loans depends largely on an individual’s financial situation and expectations regarding future interest rate movements.

A fixed-rate loan offers stability and predictability. It is ideal for borrowers who prioritise budgeting certainty and wish to avoid surprises caused by market fluctuations.

In contrast, floating interest loans offer flexibility and the possibility of lower borrowing costs when interest rates decline. Borrowers comfortable with some uncertainty may find floating-rate loans more attractive.

Here is the difference between fixed and floating interest rates in a tabular format:

When to choose fixed-interest rate loans?

Here are the scenarios when you should consider fixed-interest rate loans:

Individuals who require certainty in household finances benefit from fixed rates.

• Low risk tolerance:

Conservative borrowers may prefer a fixed rate to avoid repayment fluctuations.

• Short to medium tenure:

Fixed rates can offer peace of mind during shorter loan periods.

When to choose floating interest rate loans?

Here are the scenarios when you should consider floating interest rate loans:

• Declining rate outlook:

Floating interest loans may help reduce borrowing costs when interest rates are expected to fall.

• Long-term borrowing:

Extended loan tenures may benefit from favourable market movements.

• Income flexibility:

Borrowers with flexible financial resources may be better equipped to handle repayment variations comfortably.

Fixed vs Floating Interest Rate Loans: Which is Better?

There is no universal answer to the fixed vs floating interest rate debate because the better option depends on individual circumstances. Borrowers who value stability, predictable repayments, and protection against rising rates may prefer a fixed-interest-rate loan.

On the other hand, borrowers who expect interest rates to decline, have financial flexibility, and are comfortable with changing repayment obligations may benefit from floating interest rate loans.

Before making a decision, borrowers should carefully evaluate their personal financial goals, market expectations, and risk tolerance.
