Fixed deposits, without the fine print

A fixed deposit trades access for predictability: you lend money for a set term at a stated rate. The details still matter — how interest compounds and is paid out, who issues the deposit, what happens if you need the money early, and how the interest is taxed.

FAQs

Common questions

All FAQs

Fixed deposits are less volatile than market-linked investments, but they are not free of risk. Under current rules, bank deposits are covered by DICGC deposit insurance up to ₹5 lakh per depositor per bank; amounts above that depend on the bank’s health. Corporate and NBFC deposits are not covered by that insurance and carry the issuer’s credit risk, so check their credit rating. All FDs also carry inflation risk and reinvestment risk at maturity.

A cumulative FD reinvests interest and pays principal plus all interest at maturity, so interest compounds and the final amount is higher. A non-cumulative FD pays interest out monthly, quarterly, half-yearly or yearly, which suits anyone who needs regular income, and returns the principal at maturity. The FD Calculator shows both for the same rate and term.

Usually, yes. Most banks allow premature withdrawal but pay a reduced rate — often the rate for the period the deposit actually ran, less a penalty. Some deposits, such as tax-saving FDs, cannot be withdrawn early at all. The exact terms are set by each bank or company and stated when you open the deposit, so check them before you invest.

FD interest is generally added to your income and taxed at your slab rate, year by year as it accrues — even in a cumulative FD that pays out only at maturity. Under current rules, banks deduct TDS once interest at that bank exceeds ₹50,000 in a year, or ₹1,00,000 for senior citizens. If your total income is below the taxable limit, you can usually submit a self-declaration so tax isn’t deducted. Check the latest provisions.

Rates change often and differ by issuer, tenure, amount and depositor category. Rather than show figures that may be out of date, CompoundX displays FD rates only when they come from a configured provider, with the source and date shown. Until then, the FD Calculator lets you enter any rate you are considering and see the maturity amount, interest earned and payout schedule.
