Cumulative or non-cumulative: which FD pays more
One compounds and pays at maturity, the other pays interest out and never compounds. The rate is usually identical; the return is not, and the tax timing catches people out.

Every fixed deposit application asks you to choose between two options, usually described in a single line and often left on whichever the bank has set as the default. It is not a formatting preference. It changes what the deposit returns, when you are taxed on it, and whether the word “compounding” applies to your money at all.
The difference in one sentence
A cumulative deposit retains the interest and compounds it, paying everything as one sum at maturity. A non-cumulative deposit pays the interest out at intervals — monthly, quarterly, half-yearly or annually — so the balance never grows and nothing compounds.
On ₹10,00,000 at 7% for five years, the cumulative option matures at roughly ₹14.1 lakh. The non-cumulative option pays out about ₹3.5 lakh in interest over the same period and returns the ₹10 lakh principal. The gap is not the bank being generous to one group; it is what happens when interest is allowed to earn interest.

When non-cumulative is the right answer anyway
The lower return is not a mistake if you need the income. A retiree replacing a salary needs money arriving monthly, and a deposit that pays nothing for five years does not do that however good the arithmetic looks. Choosing the lower total return in exchange for predictable cash flow is a legitimate trade, and the only one that matters for someone living on it.
| Choose cumulative when | Choose non-cumulative when |
|---|---|
| The money is for a goal with a date | You are living on the interest |
| You have other income covering expenses | You need a predictable monthly or quarterly sum |
| You want the largest maturity value | Cash flow matters more than total return |
| The deposit is long — the gap widens with time | The deposit is short, where the gap is small |
One thing that is not a good reason: choosing non-cumulative because you expect to need the money early. Breaking a cumulative deposit is no harder than breaking a non-cumulative one, and both are penalised the same way.
The tax treatment surprises people
Interest on a deposit is taxed in the year it accrues, not the year you receive it. That sentence does most of the damage. On a five-year cumulative deposit you receive nothing until maturity, but you are liable for tax on the interest each year along the way.
The bank will typically deduct TDS annually on the accrued interest even though it has paid you nothing, so the tax leaves before the money arrives. People who assume a cumulative deposit defers tax to maturity get an unwelcome surprise, and occasionally a demand for advance tax they had not planned for.
The threshold and reclaim mechanics are the same for both options — TDS on FD interest is a withholding, not a final bill — but the mismatch between accrual and receipt only bites on the cumulative side.

Because a cumulative deposit compounds quarterly, the gap between the two options widens with tenure rather than growing in a straight line. Over one year the difference is small enough to ignore. Over ten it is substantial, and over a long enough horizon the compounded option returns close to half as much again in interest.
If you are undecided and the money genuinely has no date on it, the compounded option is the safer default — you can always break it if circumstances change, and you will have given up nothing in the meantime.
Frequently asked questions
- Do both options pay the same interest rate?
- Almost always yes — banks quote one rate for the tenure and let you pick the payout mode. A few offer a marginally different rate for monthly payout, because paying monthly costs them more in administration. Check the rate card rather than assuming.
- Can I switch after opening the deposit?
- Generally not. The payout mode is fixed at opening. Changing it means closing the deposit and opening a new one, which usually triggers a premature withdrawal penalty and re-prices the deposit at the rate for the period actually completed.
- Is a cumulative deposit taxed only at maturity?
- No, and this is the most common misunderstanding. Interest is taxed as it accrues each year, and the bank generally deducts TDS annually even though no money has reached you. You may need to plan for the tax before you see the interest.
- Which one is better for a senior citizen?
- It depends entirely on whether the interest is needed as income. Senior citizens often choose non-cumulative for exactly that reason, and they also get a higher TDS threshold on deposit interest, which reduces the withholding either way.
- What happens to a cumulative deposit if I break it early?
- The accumulated interest is recalculated at the rate applicable to the period actually completed, less the bank's penalty — typically 0.5% to 1%. The compounding you had accrued is not protected; it is recomputed at the lower rate.
