What is a Fixed Deposit?

A Fixed Deposit (FD) is a popular savings tool offered by banks and financial institutions. When you invest in an FD, your money is locked in for a specific duration, typically ranging from 7 days to 10 years. In return, you earn a higher rate of interest than regular savings accounts.

FDs are ideal for individuals looking for a low-risk, stable investment option to grow their money steadily over time.

Frequently Asked Questions

What is a Fixed Deposit (FD)? +

A Fixed Deposit is a savings instrument offered by banks and NBFCs where you invest a lump sum for a fixed tenure at a fixed interest rate, receiving the principal plus interest at maturity.

What is the difference between simple and compound interest FDs? +

Simple interest is calculated only on the principal amount for the entire tenure, while compound interest is calculated on the principal plus previously accumulated interest, resulting in higher overall returns for the same rate and tenure.

Is the FD interest rate fixed for the entire tenure? +

Yes, once booked, most fixed deposits carry a fixed interest rate for the entire tenure, so your returns remain predictable and unaffected by later changes in market interest rates.
