FD vs RD: Which Fixed-Income Option Should You Choose?

Fixed Deposits (FD) and Recurring Deposits (RD) are the two most popular safe savings options offered by banks and the post office. Both give you a guaranteed, fixed rate of interest with no market risk. The difference is not really about which is “better” — it is about whether you have a lump sum to invest now, or you want to save a fixed amount every month.

What a Fixed Deposit is

In an FD, you deposit a single lump sum once — say ₹1 lakh — and lock it in for a chosen tenure, from a few months to several years. It earns a fixed rate for the whole period, and the interest is usually compounded quarterly. Because the entire amount is working from day one, an FD earns the most interest in absolute terms.

What a Recurring Deposit is

In an RD, you deposit a fixed amount every month — say ₹5,000 — for a chosen tenure. Each monthly installment earns interest for the time it stays invested, so your first installment earns for the full term while your last earns for only a month. RD is built for disciplined, regular saving rather than parking a windfall.

Why an FD earns more than an RD (for the same total)

Suppose you compare putting ₹60,000 into an FD today versus saving ₹5,000 a month into an RD for a year (also ₹60,000). The FD earns more, because the full ₹60,000 compounds for the entire year, whereas in the RD only the early installments get a full year of growth. That does not make the RD worse — it simply reflects that you did not have the whole amount available up front.

What they have in common

• Both offer a fixed, pre-agreed interest rate with no market risk.
• Both let you choose the tenure and are offered by banks and the post office.
• The interest is fully taxable at your income-tax slab rate, and banks deduct TDS once the interest crosses the annual threshold.
• Premature withdrawal is allowed on both, usually with a small penalty on the rate.

How to decide

Choose an FD when you already have a lump sum — a bonus, maturity proceeds, or savings sitting idle — that you want to grow safely for a fixed period. Choose an RD when you want to build a habit of setting aside a fixed sum every month, for a goal a year or two away. Many people use both: an FD for existing savings and an RD to keep adding to them.
