When you book a fixed deposit, there's one choice most people rush through: how do you want your interest paid? The form usually offers "cumulative" or "non-cumulative" (with a monthly, quarterly, half-yearly or yearly option). It looks like an admin detail — but at the same interest rate, it changes how much you earn, when you get it, and how you plan your taxes.
This guide explains both options in plain language, runs a real ₹5 lakh example, covers the tax and TDS rules people often get wrong, and helps you pick the right one for your goal.

1. What Is a Cumulative FD?
In a cumulative FD, the bank does not pay out your interest along the way. Instead, interest is added to your deposit — usually every quarter — and from then on it earns interest too. You receive one lump sum at maturity: your principal plus all the compounded interest. It's also called a reinvestment deposit or interest-on-maturity FD.
2. What Is a Non-Cumulative FD?
In a non-cumulative FD, the interest is paid out to your savings account at a fixed interval — monthly, quarterly, half-yearly or yearly. Because interest leaves the deposit, it doesn't compound. At maturity you get back only your original principal. Monthly-payout versions are often called monthly income FDs.
3. ₹5 Lakh Example — Side-by-Side Returns
Let's take ₹5,00,000 for 5 years at 7.00% p.a. and see what each option delivers:
| Payout Option | You Receive | Total Interest (5 yrs) | At Maturity |
|---|---|---|---|
| Cumulative (quarterly compounding) | Nothing until maturity | ₹2,07,389 | ₹7,07,389 |
| Non-cumulative — Quarterly | ₹8,750 every quarter | ₹1,75,000 | ₹5,00,000 |
| Non-cumulative — Monthly | ≈ ₹2,900 every month | ≈ ₹1,73,990 | ₹5,00,000 |
* Illustrative calculation at 7.00% p.a. before tax. Actual payouts depend on the bank's rate and day-count method.
The cumulative FD earns about ₹32,000 more than the quarterly-payout option — purely from compounding. But the non-cumulative investor has had ₹8,750 in hand every quarter for five years. Neither is "better"; they solve different problems.
4. Why the Monthly Payout Rate Is Slightly Lower
Bank FD rates are quoted assuming quarterly compounding. If you choose monthly payouts, you receive interest earlier than the quarter-end — so banks pay a slightly discounted rate that is worth the same in value. At a 7.00% quoted rate, the monthly-payout equivalent is roughly 6.96%, which is why ₹5 lakh pays about ₹2,900 a month rather than ₹2,917.
Similarly, a yearly-payout option may show a slightly higher effective rate on some bank rate cards, because you wait longer for the money. Always check the exact payout amount the bank shows before you confirm.
5. Key Differences at a Glance
| Feature | Cumulative FD | Non-Cumulative FD |
|---|---|---|
| Interest payout | At maturity, with principal | Monthly / quarterly / half-yearly / yearly |
| Compounding | Yes (usually quarterly) | No |
| Total returns | Higher | Lower |
| Regular income | None | Yes — predictable |
| Maturity amount | Principal + all interest | Principal only |
| Income tax | Taxable every year on accrual | Taxable every year as received |
| Premature withdrawal | Penalty reduces accrued interest | Excess interest already paid may be recovered from principal |
| Ideal for | Wealth building for a goal | Retirees and income seekers |
6. Tax and TDS — The Rule Most People Miss
A common myth is that cumulative FD interest is taxed only when you receive it at maturity. It isn't. Interest accrues every year, and banks deduct TDS each financial year on the accrued amount if it crosses the threshold — currently ₹50,000 per bank per year for regular depositors and ₹1 lakh for senior citizens.
For both types, if your total income is below the taxable limit you can submit Form 15G (or Form 15H if you're 60+) to stop TDS. Read our detailed guide on TDS on FD interest for the full rules.

7. Which Option Should You Choose?
📈 Choose Cumulative if…
- You're saving for a goal 2+ years away
- You have a salary or other income for daily expenses
- You want the maximum maturity amount
- You can leave the money untouched till maturity
💵 Choose Non-Cumulative if…
- You're retired and need a pension-like income
- FD interest pays rent, EMIs or monthly bills
- You want to reinvest payouts elsewhere yourself
- You're supporting parents with a fixed monthly amount
⚖️ Mix Both if…
- You need some income but also want growth
- You're building an FD ladder
- You're nearing retirement and shifting gradually
- You want flexibility across tenures
8. Smart Tips
Payout + RD combo
If you choose monthly payouts but don't need all of it, route the surplus into a recurring deposit so it keeps earning.
Pick quarterly over monthly if you can
Quarterly payouts earn the full quoted rate. Choose monthly only if you truly need money every month.
Seniors: split for safety
Keep enough in monthly-payout FDs to cover expenses, and put the rest in cumulative FDs to fight inflation. See our Senior Citizen FD Guide.
Decide before you book
The payout option usually can't be changed later without breaking the FD — read our guide on breaking an FD early to know the cost.
Tax-saving FDs
5-year tax-saving FDs also offer both options — but either way the money stays locked for 5 years. See our Section 80C FD guide.
