Frequently Asked Questions

How often is FD interest compounded?

It varies by bank and product, but quarterly compounding is the most common default for fixed deposits — check your specific FD's terms, since this affects the final maturity value.

Is FD interest taxable?

In many jurisdictions FD interest is taxable as income, often with tax deducted at source above a threshold — confirm the current rules that apply to you with a tax advisor.

What happens if I withdraw an FD early?

Most banks apply a penalty (often a reduced interest rate) for premature withdrawal — check your specific FD's terms, since this calculator assumes the deposit runs to full maturity.
