FD laddering: how to spread money across fixed deposits

FD laddering means splitting one sum into several fixed deposits that mature in different years. One comes free every year or so, and you either use the money or renew it at the rate the bank offers then. It does not raise your interest by itself, and it does not remove the risk that rates fall by the time a deposit renews.

Spreading deposits across different banks or companies is a separate idea. This article covers both.

What is FD laddering?

A ladder is a set of fixed deposits of different lengths, so that one matures every year or so instead of all on one day. Each deposit is a rung. The name comes from the picture: maturity dates climb one step at a time.

Two words first. Maturity is the date a deposit ends and the bank returns your money with interest. Renewal is putting that money into a fresh deposit instead of taking it out.

A single large FD ties up everything until one date. With a ladder, only part of the money falls due in any one year, and the other rungs keep running.

How do you build an FD ladder?

You pick the total and the span, split the sum into equal deposits that end one year apart, and renew each as it matures if you do not need the money. The example is an illustration, not a suggestion on rungs or amounts.

Take a 49-year-old with ₹6,00,000 set aside as a family reserve that may be needed in any year. Suppose it goes into five deposits of ₹1,20,000, for 1, 2, 3, 4 and 5 years. Every rung is assumed to earn 7% a year, compounded yearly. Real rates differ by bank and tenure.

In year one, rung 1 matures. If the family does not need it, the money can go into a new five-year deposit. Repeat that each year and, from year six, a five-year deposit matures every year. Nobody knows the rate on those renewals in advance.

A renewed rung does not keep its old rate. It earns the rate under the bank's renewal policy, and the bank must state the renewal terms, including the rate, when it accepts the deposit. See auto-renewal of fixed deposits. The fixed deposit calculator lets you try other amounts and tenures.

What does a ladder do, and what does it not do?

A ladder gives you money back at regular intervals and spreads your renewals across several years. It does not, by itself, earn more than the same money would in a single FD.

Take the example above. Every rung earns the same assumed 7%, so the ladder earns no more than five deposits of the same tenure would. The gain is access, not extra interest.

The ladder also averages your renewal rates. When a rung matures, the rate on offer could be higher or lower than before. Only one rung renews at a time, so no single renewal sets the rate on your whole sum. That is averaging, not protection: if rates fall across the board, every renewal feels it.

A rate card does not always rise with tenure. SBI's general rates from 15 December 2025 were 6.25% for 1 to under 2 years, 6.40% for 2 to under 3 years, 6.30% for 3 to under 5 years and 6.05% for 5 to 10 years. Those figures are SBI's alone, for that date.

Breaking a rung early still costs you. Under the RBI's rules, a bank that pays out early pays the rate for the period the deposit actually ran, not the contracted rate, and any penalty must be disclosed when you open the deposit. SBI, for one, takes 0.50% off the rate for deposits up to ₹5 lakh and 1% for larger ones below ₹2 crore. See breaking a fixed deposit before maturity.

Why spread FDs across banks?

Deposit insurance covers up to ₹5 lakh per depositor per bank, principal and interest together, so money above that at one bank has no cover. DICGC (the Deposit Insurance and Credit Guarantee Corporation), a subsidiary of the RBI, runs this insurance. The bank pays the premium, not you.

In rupees: someone has ₹8,00,000 in fixed deposits at one bank. At most ₹5,00,000 of it, interest included, is insured there, leaving about ₹3,00,000 without cover. Now put ₹4,00,000 at each of two banks. With one year of interest at an assumed 7%, each deposit grows to ₹4,28,000, inside each bank's ₹5 lakh. That holds only if no other deposits in the same name sit at those banks.

How the limit counts:

• All your deposits in one name at one bank are added together, across every branch. FDs at different branches of the same bank add nothing to your cover.
• Two banks are two separate limits, even if both fail on the same day.
• A joint account, or an account you hold for a minor as guardian, has its own ₹5 lakh limit.
• Small finance banks and payments banks appear on the insurer's list dated 29 September 2026. Primary co-operative societies are not insured.

Spreading across banks is not a tax device. A bank on core banking counts all its branches together for TDS (tax deducted at source before money reaches you), and each bank counts only its own. Splitting changes where tax is cut at source, not how much tax you owe. Interest is taxed at your slab rate wherever it sits. See tax on fixed deposits.

How do you spread corporate FDs?

Company and NBFC fixed deposits have no deposit insurance, so spreading across several issuers limits how much any one failure can cost you. It does not make any single deposit more secure. An NBFC is a non-banking financial company: a finance company that is not a bank.

An NBFC needs a credit rating of at least BBB-, obtained at least once a year, to take deposits. A credit rating is the rating agency's opinion on whether a debt will be repaid in full and on time. It is not a recommendation to buy, hold or sell, and it can change quickly. If it falls below BBB-, the NBFC must immediately stop accepting fresh deposits and renewing existing ones. Existing deposits run to maturity.

More rules from the RBI's directions on NBFC deposits: they run for 12 to 60 months, and early repayment in the first three months is allowed only on the depositor's death. A matured deposit cannot be renewed without your "express and voluntary consent", and the NBFC must tell you at least 14 days before maturity. The application form shows the credit rating and the agency's name.

The corporate fixed deposits article covers ratings and what to check before booking. Koshex offers fixed deposits, both bank and corporate, from ₹10,000. Only the bank deposits are insured, up to ₹5 lakh per depositor per bank. You can see what is on offer at fixed deposits.

When does a ladder not fit?

A ladder suits money you may need in pieces over several years. Two factors decide whether it fits: when you might need the money, and how many maturity dates you are willing to track.

If you need all of it on one known date, one deposit of that tenure ends on that date; opening a fixed deposit explains how to pick one. If a large part may be needed in a hurry, a ladder fits poorly, because breaking a rung costs interest. Where to keep emergency savings and liquid funds versus fixed deposits cover other places for money you may need at short notice.

Tax-saving deposits are a special case. Each is locked for five years, so a ladder of them opened one a year frees one deposit a year only from year six. See what a tax-saving fixed deposit is.
