When you take a loan, you usually face a choice: fixed rate or floating rate. Banks love offering both because most borrowers pick based on gut feeling rather than analysis. Here’s how to think about it properly.

How They Work

Fixed rate: Your interest rate stays the same for the entire loan tenure (or a specified period). Your EMI never changes.

Floating rate: Your rate moves with a benchmark (like the RBI repo rate). When the benchmark changes, your EMI or tenure adjusts.

The Pricing Gap

Banks almost always price fixed rates higher than floating rates. Typically 1-2% higher. This isn’t generosity toward floating-rate borrowers. It’s the bank pricing in their own risk. With a fixed rate, the bank bears the risk of rates going up. They charge a premium for that.

When Fixed Rates Win

  • Rates are at historic lows: If rates are at the bottom of their cycle, locking in makes sense. You’re buying certainty at the cheapest possible price.
  • You need payment predictability: If your budget is tight and a 20% EMI increase would cause real stress, fixed gives you peace of mind.
  • Short to medium tenure loans: On a 3-5 year car loan, the rate environment won’t shift dramatically. The premium for fixed is small and the certainty is valuable.

When Floating Rates Win

  • Rates are high or rising from mid-cycle: If rates have room to fall, floating lets you benefit from the decline.
  • Long tenure loans: Over 15-20 years, rate cycles go up and down multiple times. The lower starting rate of floating usually wins over full cycles.
  • You can absorb payment changes: If your income comfortably covers potential EMI increases, the lower average cost of floating is worth taking.

The Historical Pattern

In India, floating rates have been cheaper than fixed rates for the majority of the last 20 years. The RBI cuts and hikes in cycles. Borrowers who took floating rates in most periods ended up paying less total interest, even accounting for the high-rate phases.

A Practical Framework

Ask yourself three questions:

  1. Where are rates in the cycle? Near historic lows? Lean fixed. Average or high? Lean floating.
  2. What’s your tenure? Under 5 years? Fixed is fine. Over 10 years? Floating usually wins.
  3. Can you handle EMI volatility? If a 15-20% EMI swing would hurt, fixed is safer.

The Hybrid Option

Some banks offer a fixed rate for the first 2-3 years that then converts to floating. This gives you near-term certainty while capturing the long-term advantage of floating rates. Worth considering if you can find a competitive one.

One Thing People Miss

With floating rates, when rates rise, many banks extend your tenure instead of increasing your EMI. This seems painless, but it means you’re paying interest for more years. Always check whether your bank adjusts EMI or tenure, and request EMI adjustment if possible.
