Fixed vs Floating Interest Rate: What’s the Difference?

When taking a home loan, personal loan, or business loan, one of the most important decisions you make is choosing between a fixed interest rate and a floating interest rate.

This choice directly affects your EMI, total interest paid, and financial flexibility over the loan tenure. With changing repo rates and evolving lending norms in India, understanding this difference has become more important than ever.

At Saarathi.ai, we have observed that many borrowers select an interest type without fully understanding how it impacts long-term repayment. In this guide, we break down fixed vs floating interest rates in simple terms so you can make an informed decision in 2026.

What Is a Fixed Interest Rate?

A fixed interest rate remains constant throughout the loan tenure or for a defined initial period.

This means:

• Your EMI stays the same

• Your interest rate does not change with market fluctuations

• Your repayment schedule remains predictable

Lenders regulated by the Reserve Bank of India must clearly disclose whether the rate is fixed or floating in loan agreements.

Advantages of Fixed Interest Rate

• Predictable EMI

• Easier budgeting

• Protection against rising interest rates

Disadvantages of Fixed Interest Rate

• Usually higher than floating rates

• Limited benefit if market rates fall

• Possible prepayment charges

Fixed rates are common in personal loans where tenure is shorter.

What Is a Floating Interest Rate?

A floating interest rate changes based on market conditions. It is typically linked to an external benchmark such as the repo rate set by the Reserve Bank of India.

If the repo rate:

• Increases → Your interest rate may rise

• Decreases → Your interest rate may fall

As per RBI guidelines, most new home loans in India are linked to external benchmark rates.

Advantages of Floating Interest Rate

• Usually lower starting rate

• Benefit when rates fall

• Often lower foreclosure penalties

Disadvantages of Floating Interest Rate

• EMI may increase unexpectedly

• Budget planning becomes harder

• Total repayment may increase if rates rise

How Repo Rate Affects Floating Loans

The repo rate is the rate at which RBI lends money to banks.

When RBI increases repo rate:

• Banks increase lending rates

• Floating loan EMIs may rise

When RBI reduces repo rate:

• Floating loan rates may reduce

Financial updates frequently covered by The Economic Times highlight how repo rate changes directly impact home loan borrowers.

Example: Fixed vs Floating Comparison

Assume you take a Rs 20 lakh home loan for 20 years.

Fixed Rate at 9.5 percent

• EMI remains constant

• No change regardless of market movement

Floating Rate starting at 9 percent

• EMI lower initially

• If rates rise to 10 percent, EMI increases

• If rates drop to 8.5 percent, EMI reduces

The difference over 20 years can amount to lakhs.

Which Option Is Better for Personal Loans?

Most personal loans in India come with fixed interest rates because:

• Tenure is short

• Risk for lenders is higher

• EMI predictability is important

You can compare personal loan offers on Saarathi.ai to see interest type and tenure options across lenders.

Which Option Is Better for Home Loans?

Floating rates are more common in home loans because:

• Tenure is long

• Market rates fluctuate over time

• RBI repo rate linkage ensures transparency

However, borrowers who prefer stability may choose fixed rates.

Factors to Consider Before Choosing

1. Interest Rate Trend

If rates are expected to rise, fixed rate may protect you.

If rates are expected to fall, floating rate may benefit you.

2. Loan Tenure

• Short tenure: Fixed may work well

• Long tenure: Floating may offer flexibility

3. Risk Appetite

If you prefer predictable budgeting, a fixed rate is safer.

If you can handle EMI fluctuations, floating may reduce long-term cost.

4. Prepayment Plans

Floating loans often have lower or zero foreclosure charges for individuals.

5. Credit Profile

Lenders assess your credit history through TransUnion CIBIL before offering rates. A higher score may fetch better pricing in both options.

Can You Switch Between Fixed and Floating?

Some lenders allow switching between rate types for a fee.

Options include:

• Conversion charges

• Balance transfer to another lender

• Refinancing

Always calculate total cost before switching.

How EMI Changes in Floating Loans

When rates rise, lenders may:

• Increase EMI

• Extend tenure

• Or adjust both

Understanding this clause in your loan agreement is important.
