Key Takeaways
- Fixed rates give certainty; floating rates move with a benchmark.
- Floating rates fall when benchmarks fall — and rise when they rise.
- Fixed-rate loans may carry a slightly higher starting rate.
- The right choice depends on rate outlook and your need for certainty.

Fixed rate
With a fixed interest rate, the rate — and therefore your EMI — stays the same for the agreed period. This gives budgeting certainty and protection if market rates rise, but you will not benefit if rates fall.
Floating rate
A floating rate is linked to a benchmark, so it moves up or down as that benchmark changes. When rates fall, your interest cost drops; when they rise, it increases. Lenders typically adjust either the EMI or the tenure to absorb the change.
How to decide
If you value predictable payments and expect rates to rise, a fixed rate can be reassuring. If you can tolerate variability and expect rates to fall or stay stable, a floating rate may cost less overall. Because rate outlooks are uncertain, many borrowers weigh their own need for certainty most heavily. Model different rates in the EMI calculator to see how sensitive your EMI is to rate changes.

How Is EMI Calculated?
An EMI is calculated with a standard formula from the loan amount, the monthly interest rate, and the number of months. Each EMI pays some interest and some principal.
loansHow Loan Interest Works
Most loans charge interest on the reducing outstanding balance, so interest falls as you repay. A flat rate charges on the original amount throughout and is effectively costlier.
loansHow Loan Prepayment Works
Prepaying a loan reduces the outstanding principal, which lowers future interest. You can usually choose to shorten the tenure or reduce the EMI — shortening tenure saves the most interest.
